Welcome
What is the F20 used for?
The Filmetrics F20 is used to measure the thickness and optical constants (n and k) of dielectric and
semiconductor thin films. Measured films must be optically smooth and within the thickness range
set by the system configuration requirements specified in Performance Specifications. Commonly
measured films include semiconductor process films such as oxides, nitrides, resists, and polysilicon, optical coatings such as hardness and anti-reflection coatings, flat panel display films such
as polyimides, resist, and cell gaps, and the various coatings used in CD and DVD manufacture.

Disclaimer:Use of this instrument in a manner inconsistent with the information and directions
included in this manual may impair the protections designed into the product resulting in danger to
the operator or damage to the instrument
Installation Location: When deciding on a location for the instrument, ensure that the instrument
in installed in a well-ventilated location. Enclosing the unit, or blocking the vent holes, may impair
the performance of the instrument of damage the internal components.
Cleaning:The need for periodic cleaning of the system is based on the cleanliness of the environment in which the system is installed. Only the external surfaces are to be cleaned. Cleaning
and maintenance of all internal components is to be performed by a trained service technician. Do
not use aerosol, or spray, cleaners as they may contaminate the sensitive optical surfaces on the
instrument.
Before performing any service on the instrument ensure that the main power is disconnected.
Cleanroom, or low lint, wipes should be used to wipe down the system. A mixture of Isopropyl
Alcohol (IPA) and De-ionized Water (DI H2O) at 70% DI H2O: 30% IPA is to be used for cleaning. Undiluted IPA may be used, if the 70:30 DI and IPA mixture is not available, but extra care
must be taken. Avoid using stronger solvents, such as acetone, as these may compromise the surface finish.
Avoid excessive pressure on any surface when cleaning. Excessive force may bend a component,
which would damage the system, or cause the system to be out of alignment.
Start with the top of the system and work down. Use slow motions, in a straight line, from the back
to the front of the surface being cleaned. Change the cleaning wipe periodically to avoid re-depositing material back onto the surface being cleaned. Allow all cleaned surfaces to dry completely
before restoring power to the system.

Software Overview
The way that light reflects off of a thin film is determined by the characteristics of the film, such as
its thickness, optical constants, and roughness. The F20 is able to determine thin-film characteristics by first carefully measuring the amount of light reflected from the thin film over a range
of wavelengths (i.e., by measuring the reflectance spectrum), and then analyzing this data by comparing it to a series of calculated reflectance spectra. Most of the features of the FILMeasure software that runs the F20 can be divided into reflectance acquisition and reflectance analysis
functions. The following pages outline the main features of the FILMeasure software.
The basic steps for any F20 measurement are selecting and editing the film structure, taking a baseline measurement, and then making and evaluating the measurement. The details of each of these
steps are explained below, followed by descriptions of other FILMeasure functions.

16. Deletes the selected layer
17. This pulldown menu allows the user to select the desired material file. Also, left-clicking on the
text will open the Search Materials dialog box.
Editing Film Structures
The description of the nominal film structure, as well as the measurement parameters, is specified
in the Edit Recipe dialog box. Dozens of different film structures and their measurement specifications may be saved using the Edit Recipe dialog box.
The Edit Recipe dialog box is accessed with the Edit Recipe button on the Measure Tab. The
Edit Recipe dialog box lists an initial guess at the specifications of the film structure to be measured. These specifications include the name of the film structure (which identifies it in the Recipe:
list), the number of films in the structure, the specifications of individual films, and the quantities to
be measured.
Adding, Changing, or Deleting a Structure
When the dialog box is opened, it shows the stored specifications of the structure selected from the
Recipe: list, along with any changes made since the program was started. Changes to the structure
selected can be permanently stored by making the desired changes and then clicking on Save
Changes. New structures may be added to the Recipe: list by opening the Edit Recipe dialog
box, setting the desired specifications, and then clicking on Save As. Similarly, a structure may be
deleted (removed from the Recipe: list) by clicking on the Delete Recipe button.
Edit Recipe>Film Stack window.
Film Stack
The Film Stack tab is used to define the film structure, as well as the starting guesses and constraints for thickness, n and k. This is also where you determine your analysis method, Grid, FFT ,
or None, as well as any Non-Uniformity that may be present in the sample. Additional options for
Composition, Thickness and Non-Uniformity can be selected or hidden by using the + and - buttons.
Setting Up a Film Stack
When measuring a layer, the specifications (d, n, k, and roughness) of the known films (including
the incident medium and substrate) must be entered into the proper fields in the Edit Recipe dialog
box, as well as initial guesses for the values to be measured. The refractive index (n) and extinction
coefficient (k) values for common materials can be selected automatically with the pull-down
menus on the left-hand side of the Edit Recipe dialog box, or by clicking on the box and using the
Search function.
If a material is being measured which is not present in the material library there are three possible
approaches:
a) choose a material in the library that is similar.
b) if the material is transparent (an insulator), select “Enter Refractive Index Value” from
the material list and enter a value for the refractive index (n will automatically be varied by
FILMeasure to account for dispersion effects, with the entered value being n at 632 nm).
c) in the Edit>Material Library… dialog box, enter the refractive index values for n and k as
a function of wavelength and save the files so that they may be selected as in a). See Creating
and Editing n and k Files for more information.
Choosing the Films to be Measured
To measure a film's thickness, check the Vary box on the right-hand side of the Film Stack field
in the Edit Recipe dialog box. When no boxes are checked, the theoretical spectrum for the specified layer stack and thicknesses will be displayed.
As with most measurements, the uncertainty of the measured data increases as the number of simultaneously measured values increases. Thus it is best to provide as much information about the film
structure as possible.
Constraints
By setting constraints, the user can limit the possible values of the measured film properties. The
constraints are set in conjunction with the values entered in the Range dialog box for thickness.
For example, if the initial guess of the measured thickness of a film is 100 nm and the thickness
constraint is set at 50%, FILMeasure will only consider possible thicknesses in the range 50 nm to
150 nm. The constraints for n and k are set using the n and k dialog boxes under Composition.
These boxes are only visible when the Composition option is expanded. You can select between
constraining by a percent of the thickness guess, or by a selected thickness by clicking on the % or
measurement unit above the constraints dialog box. Constraining the measurement range can speed
up the measurements and can also help exclude non-physical solutions.
nk Model
When measuring n and k for a film, the general dependence of these values upon wavelength must
be specified. This dependence is determined by the type of material to be measured. For example,
insulators, semiconductors, and metals all have a unique type of n and k wavelength dependence.
Dozens of models for these different dependencies have been proposed and used over the years.
FILMeasure uses a few of the most versatile and accepted of these models. For insulators, the Cauchy model is used, for semiconductors, either the Amorphous or Bridge-Lorentzian model, and for
metals, the Drude model. There are also a number of special-purpose models for specific applications. These models, and starting coefficients values, are selected automatically when a material
is chosen from the Material lists in the Edit Recipe dialog box. Other models may also be spec-
ified by selecting them from the nk Model pulldown menu under the Composition tab which is
accessed by right clicking on the Vary checkbox.
Fourier search for thickness
The FFT option in the thickness dropdown is an alternative option to let FILMeasure choose an initial thickness for analysis. The Fourier Transform method analyzes the oscillations present in the
spectrum and determines the film thicknesses based on the periodicity of those oscillations. It is
somewhat less robust than the Grid method, but is better at finding the correct thickness in cases
where the shape of the initial theoretical spectrum is different than the measured data (i.e., the reflectance spectrum is non-ideal in some way) or in cases where there is more than one film thickness is
being measured.
Grid search for thickness
There are a number of methods that FILMeasure can use to determine thickness. None is perfect –
each is a different trade-off between speed, accuracy, and robustness (i.e., the ability to find the
best solution among many that are nearly as good). Because thickness can vary over many orders
of magnitude and many near-solutions exist, it is often best to use a very robust method to get close
to the best solution, and then let a more accurate method take over. One very robust method is the
Grid method, which can be activated by selecting the Grid option in the thickness dropdown. The
Grid method searches the entire allowed thickness range (as defined by the initial guess and the
constraints) to find the best initial thickness. However, on some very complex multilayer spectra, it
is possible for the Grid method to become confused and give the wrong answer. In such cases it is
best to use the Fourier Transform method to determine initial thicknesses, or to provide them
manually.
Non-Uniformity
Selecting this option enables modeling of thickness non-uniformity within the measurement spot.
An initial guess for Non-Uniformity must first be made, and then solving can be enabled or dis-
abled by toggling the check box.
Search
The Search Materials dialog box is accessible by left clicking on a material name in the Edit
Recipe > Film Stack tab. This feature allows the user to search for materials by using either the
materials name, or a keyword for a certain class of materials. The search function will also show a
brief Description of the material selected, as well as any Synonyms or Keywords related to the
material file. The Similar Materials box will list any materials that may have similar optical prop-
erties.
Analysis Options
Correct setting of the following options will help ensure accurate measurements. Many of the
options are set automatically when film information is supplied in the Edit Recipe dialog box, and
all of them can be saved so that subsequent measurements can be made as quickly and easily as
possible. If Robust (Adaptive; Thickness Only) or FFT (Thickness Only) is checked, only the
Data Selection settings will be accesible.
Data Selection
Wavelength Range
This sets the wavelength range of data that is to be analyzed. It may be either the range displayed
on the current graph or a fixed range. Wavelength range may also be changed by dragging the
ends of the gray bar near the bottom of the graph area.
Smooth ing
This function performs wavelength-dependent boxcar averaging on the measured spectra. This can
improve signal-to-noise levels and can filter out oscillations that correspond to optical thicknesses
(defined as index multiplied by thickness) equal or greater than the specified value. This value
should be lowered to increase smoothing, and raised to decrease smoothing. To eliminate smoothing, a very high value (for example, 1000 um) should be entered.
Source Dat a
If both are present, this tells the software whether to analyze the reflection data, transmission data,
or both. Only possible on spectra from the F10-VC, F10-RT, and F10-PARTS.

Analysis Options: Advanced
Advanced Analysis Options for SpectrumMatching.
Convergence Criteria
This sets the minimum GOF between the measured and calculated spectra that is attained before
the measurement routines consider the solution final. In most cases a value of 0.999 is sufficient.
For cases where the desired GOF is not attainable, the value in the Maximum Iterations field lim-
its the number of iterations performed by the analysis routine.
Solver Cycles
This option will enable multiple solver cycles, with the number of cycles being defined by the
number included in the box. When using this option, the software will run through the model for a
solution once, and then try again starting from the solution previously found. A greater number of
cycles will lead to a slower analysis.
Display Details
This feature controls the wavelength at which n and k are displayed in the Measurement Details
portion of the main screen. These values are only displayed if solving for n or k is enabled in the
Film Stack window.
Advanced Analysis Options for FFT Analysis.
FFT Analysis Window
When the FFTsolver is enabled, the advanced options gives you options to help Optimize the performance of the analysis. When optimize position is enabled, The solver with check for the best
possible GOFvalue in different areas across the spectrum as defined by the window size. For
example, if a window size of 200 nm is selected, the solver will look at six different 200nm sections of the spectrum, and then select the range the provides the best GOF.
If Optimize Size is enabled, the solver will instead begin with a minimum window size as defined
by the user. It will then start at the center of the analysis range, and then extend equally in both
directions six times to find the best GOF. When Optimize Position and Size is selected, the software does both functions, resulting in measuring thirty-one different combinations of location and
analysis range.
Exact Spectrum Matching
Unmodelled Back-Side Reflections
When measuring films in transparent substrates, reflectance off of the backside of the substrate may
occur. Selecting compensate for Unmodelled Back-Side Reflections allows the software to shift
the intensity of the reflectance curve to account for the additional light. This feature should not be
used when measuring very thin films (< 100 nm).
Tilted Sample/Lost Light
Samples with nonplanar surfaces scatter some of the light away from the collection optics. This
option automatically compensates for the light lost due to nonplanarity.
Lock Identical Layers
Samples comprised of repeating layers can be more accurately measured by activating this option.
By activating these options, all properties of any layers that initially have the same material or thickness are locked together.
Display Details
When solving for n and k, the values displayed in the Results Summary box of the Measure Tab
will be the values determined for the wavelength entered here.
Enable Robust (Adaptive; Thickness Only)
If thickness of a single-layer film is the only property to be measured and the film is greater than
150 nm, then the Robust (Adaptive;Thickness Only) mode is often recommended. This mode
can oftentimes result in successful measurements when the reflectance data is affected by non-ideal
film properties, such as thickness and composition non-uniformities and birefringence. The range
of thicknesses tested is constrained by the limits set in the Constraints field in the Film Stack tab.
Selecting this feature will limit the Analysis Options tab settings available.
Enable FFT (Thickness Only)
If thickness is the only property to be measured and the film is greater than about 250 nm, then the
FFT (Thickness Only) mode can be used. This mode is usually the most effective technique when
the sample has multiple film thicknesses to be measured. Selecting this feature will limit the Anal-
ysis Options tab settings available.
Acquisition Settings
This menu lets the user control sampling settings, active spectrometers (on EXR and UVX systems), and required baseline reference.
Measurement Timing
Use Recommended Sampling Time
Selecting this option uses the sampling time that has been automatically calculated by the software
during the baseline procedure. This value is the total sampling time and not necessarily the integration time. To see the integration time and number of integration cycles go to the Help > Diag-
nostics menu.
Use Maximum Sampling Time
Users can set a maximum sampling time by selecting this option. This option allows the user to
tradeoff between measurement speed and improved signal-to-noise.
Use Manually Set Parameters
Users can set the integration time per acquisition cycle and set a number of integration cycles over
which to average. When using this option, the total sampling time is equal to the integration time
multiplied by the number of integration cycles.
To set the integration time manually, set the sample on the stage and select Setup>Raw Signal…
If the proper integration time is unknown, an initial value of 40ms is a good starting guess. The vertical scale of the spectrum extends from zero to 4095. Thus, a good working level is when the peak
height of the sample being measured, or the reference sample, whichever is greater, is 3000-3500
counts. (Note: if the reference measurement saturates – Detector Saturation error – then spurious
final measurements will result.) If the maximum signal is too low, increase the integration time.
Too large an integration time will result in excessive dark current, so it is sometimes necessary to
accept a smaller signal level to limit the dark current.
* * Note * * If the integration time is changed, it will be necessary to perform the baseline procedure, or re-acquire the background and reference scans.
Spectrometer Type
EXR and UVX systems have two spectrometers (VIS/UV and NIR). Here the user can choose to
use only one or both spectrometers.
Alarms
GOF Error
Constraining the GOF Error will exclude measurements where the calculated GOF does not
reach the specified limit. A warning or “Invalid” result will appear if the GOF constraint is not
met. Specify 0 to have all solutions reported.
Activate Alarms
When Activate Alarms is selected, an alarm will trigger if the measured thickness of the sample is
outside the specified Thickness Limits.
Thickness Limits
Setting the minimum and maximum allowable thickness limits will trigger an alarm if the measured
thickness is outside the limits when Activate Alarms is selected.
Understand and Evaluating Measurement Results
This section covers information on the Display of Measured Spectra and a more in depth look at
the Goodness Of Fit value.
Display of Measured Data
Once film stack and measurement information have been entered and baseline spectra taken, measurements may be made by clicking on the Measure button. After measurement, the measured and
calculated reflectance spectra are displayed on the graph. The thickness of the films are listed in the
results box. If any of the thickness values were measured, they are displayed in bold numbers.
Goodness of Fit
The accuracy of a calculation fit, and thus the reliability of the measurement, can be judged by the
match between the measured and calculated spectra, which is quantified by the GOF value. GOF
is a number between 0 and 1. 0 is a poor fit.
A perfect match between measured (blue) and theoretical (red) spectra will result in a GOF of 1.0.
To ensure accurate results the user may set a minimum acceptable GOF value by entering a
number between 0 and 1 into GOF Error on the Alarms Tab in Edit Recipe. A warning message will be displayed after each measurement where the GOF falls below the user-specified GOF
Error. If the GOF is less than 1.0 there are several possible causes as follows:
a) Nonuniformity – Any variation of layer thickness, or presence of roughness, within the
measurement spot will result in a reduction in reflectance. In severe cases the interference
peaks may disappear entirely.
b) Incorrect Structure Definition – If the refractive index of one or more layers in the struc-
ture is different from what is described in the layer structure, then there may be some mismatch between the blue curve and the red curve.
c) Graded Interfaces – The amplitude of the peaks in the spectrum depends on both the size
of the change in refractive index at each interface in the layer structure and the sharpness of
the interface. In many hardcoat samples you will find that there is some degree of layer intermixing at the interface, leading to a weaker than expected reflectance at that interface. In
severe cases the peaks may disappear entirely.
