CAUTION

Incorrect rotation direction with the stops disabled will cause permanent damage rendering transducer inoperative. See Figure 1-2 on page 1-5 for proper direction of rotation.

The CrystalSix® sensor is a (six crystal) quartz crystal deposition monitor transducer. When the monitor crystal being used fails a new crystal is advanced into position, fully replacing that crystal’s function. The mechanism used for providing this motion is pneumatically powered. The logic for automatic operation of this transducer is conveniently provided on most current INFICON Deposition Controllers. It is manufactured under US Patent #5,025,644, with foreign patents pending.

Chapter 2

Sensor Installation

Successful operation of any crystal sensor depends on proper placement, compatibility of its construction with its operating environment and connection to proper utilities.

NOTE: The sensor head, water tubes, cable, etc. should be clean and grease free when installed in the vacuum chamber. These parts should be handled while wearing clean nylon gloves. If parts do become contaminated, clean them thoroughly using a suitable solvent to avoid outgassing and excessive peeling of deposition material from the sensor’s surfaces.

CAUTION

Incorrect rotation direction will cause permanent damage rendering transducer inoperative. Refer to Figure 1-2 on page 1-5 for proper direction of rotation.

2.1 Crystals in the CrystalSix Sensor

2.1.1 Handle the Crystal with Care

Always use clean nylon lab gloves and clean plastic tweezers when handling the crystal. Handle the crystals only by their edges. Anything that comes in contact with the crystal surfaces may leave contamination, which may lead to poor film adhesion. Poor film adhesion will result in high rate noise and premature crystal failure.

CAUTION

Do not use metal tweezers to handle crystals. Metal tweezers may chip the edge of the crystal.

2 - 1

CrystalSix Operating Manual

2.1.2 Care of the Ceramic Retainer

CAUTION

Do not use excessive force when handling the Ceramic Retainer Assembly since breakage may occur. Always use the crystal snatcher.

To prevent scratching the crystal electrode, do not rotate the ceramic retainer after installation.

Always use clean nylon lab gloves and plastic tweezers for handling the crystal. This avoids contamination which may lead to poor adhesion of deposited material to the electrode.

Follow the procedure below to install or replace the crystals in the CrystalSix sensor. (Reference Figure 1-3 on page 1-6).

CAUTION

Rotating the unit in the wrong direction with the stops disabled will cause severe damage! Do not rotate the unit by hand to install the crystals or to check indexing.

1Remove the heat shield (item #8) by gently pulling on the outside circumference of the shield. The shield should snap off.

2Since the crystal holders are packaged separately, skip the remainder of this step for first-time installations. Using the crystal puller (IPN 750-279-P1, provided in ship kit 750-268), remove the crystal holder by pushing the tips of the crystal puller over the outside circumference of the crystal holder (see Figure 2-2 on page 2-4). Gently pull the crystal holder from its receptacle. A slight amount of pressure applied to collapse the tips of the crystal puller may be required to extract the crystal holder.

3Insert the tapered end of the crystal snatcher (part number 008-007) into the ceramic retainer (A) and apply a small amount of pressure. This locks the retainer to the snatcher and allows the retainer to be pulled straight out (B). See Figure 2-1.

CrystalSix Operating Manual

Figure 2-1 Using the Crystal Snatcher

4Invert the crystal holder and the crystal will drop out. (Skip this step for first-time installations.)

5Install the new crystal per section 2.1.1 on page 2-1 and section 2.1.2 on page 2-2.

6Using clean nylon gloves, grasp the edge of the new crystal with a clean pair of plastic tweezers. Orient the crystal so the patterned electrode is facing up. Gently insert the edge of the crystal beneath one of the wire segments that protrude into the crystal cavity. Release the crystal.

7Replace the ceramic retainer. Initially orient it at an angle to displace the spring wire segments in the crystal holder.

8Release the crystal snatcher with a slight side-to-side rocking motion. Using the backside of the crystal snatcher, push on the ceramic retainer to ensure it is completely seated.

9Position the crystal holder between the tips of the crystal puller as illustrated in Figure 2-2.

10Push the crystal holder into the receptacle of the CrystalSix sensor until completely seated. “Snap” the crystal puller to one side to release the crystal holder from the crystal puller. Using the non-slotted end of the crystal puller, apply pressure to the crystal holder until it is completely seated. Verify that the crystal fail signal on the controller display disappears. If the crystal fail signal does not disappear, consult section 4.5 on page 4-9.

11Press the crystal switch button on the hand held controller or the controller front panel. The sensor will advance to the next crystal position. Repeat procedure from Step 2 until all six new crystals have been installed.

12Install the heat shield (item #8) by first orienting the slot in the heat shield to accommodate the water tubes, then secure the heat shield by applying pressure near the center of the shield. The shield should snap in place.
