The EIES-IV Guardian uses Electron Impact Emission Spectroscopy (EIES) to
control vacuum deposition of thin films.
In EIES, the material being deposited is energized by a thermionic emitter, which
creates optical emission spectra. An optical filter passes a characteristic
wavelength of the spectra to a detector, which measures the intensity of the
emission. The measured intensity is fed to a PID control loop, which generates a
control signal for the material's evaporation power supply. By proper filter selection,
multiple detectors can control deposition of multiple materials simultaneously.
The EIES-IV Guardian consists of five basic elements: controller, sensor(s),
detector(s), software, and an optional quartz crystal monitor. A four channel, two
sensor system is shown in Figure 1-1. Actual installation must consider source to
sensor alignment requirements, see section 4.2.1, Sensor Position, on page 4-3.
The EIES-IV Guardian Controller serves as the interface between the EIES
sensor(s) and detector(s), the evaporation power supply, and the computer running
the EIES software. See Figure 1-2.
Figure 1-2 Guardian Controller with Detector
The controller supplies power to both the filament of the sensor assembly and to
the detector modules. It communicates with each detector, passing the detector
measurements to the computer running the EIES program. Control voltages for
evaporation power supplies are also generated in the controller. Finally, relays and
digital inputs to operate shutters, etc., are included in the controller.
The controller is operated from a computer running the EIES software via RS-232
or Ethernet. Other than a power switch and a few status LEDs, there are no
operator controls on the EIES-IV Guardian Controller.
1.3 EIES Sensor
In the sensor assembly, see Figure 1-4, high-energy electrons from a hot filament
excite the valence electrons of the deposited material. These excited electrons
emit light at wavelengths that are characteristic of each material. A light tube
conducts the light to a feedthrough with a viewport, where it is measured by the
Photomultiplier Tube (PMT) of the detector module(s). A single sensor, see Figure
1-3, can be used to create emissions from multiple materials.

The sensor assembly consists of a 1.33 in. sapphire viewport attached to a 2.75 in.

flange. On the vacuum side of the flange, a telescoping light tube and two
electrical connections are attached to the thermionic emitter. The telescoping tube
can be adjusted to locate the thermionic emitter in the vapor flux.
In the Gas Compensating Sensor, Figure 1-5, two sensors are stacked on the same
optical tube with the gas compensating sensor rotated 90 degrees out of the vapor
stream.
NOTE: The sensor will not pass through the 2.75 in.CF (NW35CF) port. If the
chamber is too small to allow installation from the inside, a 4.5 in. CF
(NW63CF) or larger flange adapted to the 2.75 in. CF flange is required to
For multiple materials, a fiber optic beam splitter is attached to the viewport. The
split signal is then fed to multiple detectors. Splitting the signal reduces its intensity.
Each detector is fitted with a filter specific to the material it measures.
1.5 EIES Software
The EIES software provides the user interface, see Figure 1-7, for operating the
EIES-IV Guardian system. The program provides all of the functions required for
an eight sensor, eight output, multi-layer co-deposition controller. Process settings,
numeric data, and graphs can be displayed during all phases of deposition.
®
The EIES software stores process recipes in a Microsoft
database. Process data is logged to disk in comma-delimited format for easy import
IPN 074-517-P1D
into spreadsheet and graphing programs, such as Microsoft Excel
In the EIES system, rate is proportional to light intensity, measured as detector
current. To calibrate the detector current to actual rate, an optional quartz crystal
monitor (QCM) is available.
The EIES system uses the INFICON SQM-242
for QCM calibration of the EIES detector(s). QCM calibration can be initiated by the
user, or automatically at regular intervals during deposition. Control of a source is
also possible with a QCM input.
A separate Operating Manual covers installation of the SQM-242 or Q-pod, and
hook up of the quartz sensors.
1.7 Analog Measurements
The INFICON SAM-242™ analog input card measures four 0 to +/-10 V (dc)
signals. The SAM-242 card can be used to measure process parameters, such as
temperature and pressure, to control those process variables. The SAM-242 card
is an add-on for the SQM card and is not a stand-alone card.
The SAM-242 card is also installed in the computer running the EIES software.
Installation is covered in the SQM-242 Operating Manual.

This section covers the minimum system connections and software setup needed
to run the EIES-IV Guardian system. Consult later chapters for more detailed
installation and operating instructions.
2.2 Installation
2.2.1 Sensor Installation
Placement of the EIES sensor is the most significant factor determining EIES
system performance. The sensor must be placed so that the material vapor flux
reaches the sensor without obstruction. The sensor opening must be oriented so
that material can pass through the sensor without accumulating inside the sensor,
with the smaller sensor cutout toward the flux. See Figure 2-1. See Chapter 4 for
detailed installation instructions.
To install the sensor, loosen the collar that secures the telescoping tube and
separate the 2.75” flange from the sensor assembly. Install the 2.75 in. CF
feedthrough to the vacuum chamber port, with the telescoping tube inside the
chamber.
2.2.1.1 Sensor Covers, High Rate and Standard Rate
The High Rate cover 016-205-P1 is shipped installed on the flux sensor. The
Standard Rate cover 016-205-P2 is shipped separately in a poly bag. For MBE and
other applications where the sensor receives deposition rates below 10 Å/s or the
emission signal is weak, the Standard Rate cover may be preferable as it allows
more evaporant to enter the sensor. When replacing covers, be sure the cover is
securely snapped in place.
Figure 2-2 High Rate and Standard Rate Covers
2 - 2
In the vacuum chamber, slide the sensor assembly onto the telescoping light tube
and adjust the length so that the vapor flux passes through the sensor. The smaller
opening in the sensor cover points toward the evaporant. If necessary, provide
mechanical support to stabilize the sensor assembly. However, do not block the
flux path. Secure the assembly by tightening the tube collar.
Attach the cables from the feedthrough to the sensor. For a standard sensor, attach
the in-vacuum cable to the pins marked "F" (Flux). For a gas compensating sensor,
attach the cable from the outermost sensor to the pins marked "F". Attach the
in-vacuum cable from the inner sensor to the pins marked "G" (Gas). Assure there
are no potential shorting paths to the chamber. The outermost sensor’s cover must
be aligned to allow evaporant material to pass through it, entering at the smaller
rectangular opening and exiting at the large opening. The gas sensor will be
oriented at a right angle relative to the flux sensor and its cover will have several
small holes to permit residual gas to enter, but no evaporant material.
For single detector applications, the detector may be mounted directly to the
sensor assembly viewport. Please see section 4.3.2, Single-Detector Systems, on
page 4-8 for detailed installation instructions.
2.2.3 Sensor to Fiber Optic Installation
In multi-material applications, a fiber optic beam splitter attached to the viewport
can tailor signal transmission and detector mounting to your needs. Contact
INFICON for fiber optic beam splitting requirements and capabilities. Please see
section 4.3.3, Multiple-Detector Systems, on page 4-8 for detailed installation
instructions.
Be sure power to the PMT Detector Module is turned off
whenever the PMT is exposed to room light to avoid
damage to the PMT.
Mount the controller in a location that allows easy wiring access to the EIES sensor
and detector assemblies. The controller may be placed up to 25 ft. from the EIES
computer. See section 4.6, Controller Installation, on page 4-17
Properly ground the system. Connect a heavy braided
cable from the EIES controller to vacuum chamber
ground. If you are using multiple power supplies, be sure
that the outer conductor of each BNC cable is at system
ground potential.
Digital Inputs and Relays: Consult Chapter 4 for information on digital I/O wiring.
A system interlock must be present. Plug the Interlock
connector 782-505-077 (jumpers pin 1 to 10 and pin 3 to
16) supplied in the 782-703-G1 Ship Kit into the Inputs
connector. Emission cannot be turned on unless this
connector or an equivalent system interlock is present.
Power: With the power switch OFF, connect the AC mains to the controller power
input. The controller automatically accepts 100-240 V (ac), 50-60 Hz.
NOTE: Observe the power-up sequence described below to avoid power glitches
appearing at the evaporation power supply outputs during startup.
Power up in this sequence: Press the power switch on
the Guardian controller. Next, start the EIES Software.
Last, turn on the evaporation power supplies.
Verify that the power cable provided is connected to a
properly grounded mains receptacle.
