The Material’s display is frozen at the last thickness value. NOTE: In STOP Cygnus 2 will accept a START provided a valid crystal is available for the Material being started. 3.5 Special Features Cygnus 2 has several special features to enhance the performance of the instrument.
Power-up initialization is performed on a dual sensor to verify that the secondary crystal is good. If a crystal fail occurs while in Deposit, Cygnus 2 will switch to the second crystal and continue. The Failed Crystal list can be cleared while in Deposit by pressing the F4 function key on the Sensor Information screen with the cursor positioned on the appropriate Sensor number.
Cygnus 2 pulses again and rechecks the position. If position 1 is not detected or after 13 pulses of the wrong value, Cygnus 2 reports a Crystal Sw Fail message. In that case, all crystals are also marked as failed, except for current position status.
After a crystal switch sequence, Cygnus 2 will attempt to find the resonant frequency for the crystal in this position. If Cygnus 2 does not find a good resonant frequency for this crystal, it will again pulse the Crystal Switch Output and attempt to find a resonant frequency at the next position.
The selection of a particular crucible for a Material is defined in the Material page. 3.5.3 Auto-Z The Auto-Z feature of Cygnus 2 automatically determines the Z-Ratio of a crystal. This feature is enabled on the SENSOR page of the SENSOR screen. For the theory behind Auto-Z, see section 14.1.6, Auto-Z Theory, on page...
Page 75
As mass is deposited onto the crystal, the oscillation is damped. This damping may be severe enough that the resonance can no longer be determined. If Cygnus 2 loses the ability to measure the first anharmonic frequency, but is still able to determine the fundamental frequency, the “unable to Auto-Z” message is displayed.
2. The Handheld Controller serves as a wired remote to manually control power, switch crystals and produce a STOP. The Handheld Controller is attached to Cygnus 2 with a modular plug to the front panel. Power is affected only when in Manual mode by moving the POWER/STOP switch laterally.
Test mode is active. 3.5.6.1 Standard or Time Compressed This Cygnus 2 contains a software-controlled test mode which simulates actual operation. In Time Compressed mode, all Material times are sped up so that a long process can be simulated in one tenth of the time. The purpose of the test mode is to verify basic operation and to demonstrate typical operation.
The parameter set may be stored under a new or existing filename and retrieved from an existing file. A file containing the Cygnus 2 parameter set is referred to as a configuration file. Datalog information will be saved only if the USB Datalog Format setting in the Datalog page of the USB Storage screen is set to Comma or Page.

The tooling factor can be experimentally established by following the guidelines in section 10.3 on page 10-2. In Cygnus 2, if the Z-Ratio is not known it could be estimated from the procedures outlined in section 10.4 on page 10-3, or, typically, the Auto-Z function can be used to determine the Z-Ratio.
A quick check of the calculated density may be made by programming Cygnus 2 with the new density value and observing that the displayed thickness is equal to the measured thickness, provided that Cygnus 2's thickness has not been zeroed between the test deposition and entering the calculated density.
Cygnus 2 Operating Manual 10.4 Laboratory Determination of Z-Ratio NOTE: On Cygnus 2, the Auto-Z function is available to automatically calculate the Z-Ratio. Especially when precise Z-Ratio values are significant, Auto-Z is recommended. See section 14.1.6 on page 14-9 for a description of Auto-Z theory.
Page 199
Cygnus 2 Operating Manual Using the density value from step 1 and the recorded values for F and F adjust the Z-Ratio value in thickness equation [5] to bring the calculated thickness value into agreement with the actual thickness. If the calculated value of thickness is greater than the actual thickness, increase the Z-Ratio value.

Counters and Timers 11.1 Introduction Cygnus 2 has twenty counters and twenty timers. These counters and timers enable you to customize logic statements. Timers and counters are "up/increasing" value variables. You can increment a counter or start a timer on any event via a logic statement.
USB port storage device. To prevent loss of data, no more than 500 data log files should be written to the USB device. Cygnus 2 will only display the first 120 files (15 per page) and a message "More Files on the USB". All files will be displayed on a computer.
Cygnus 2 Operating Manual 12.3 Configuration Files With all Materials in the READY or STOP state, the configuration of Cygnus 2 may be sent to a storage device attached to the USB port. Configuration files will be written with the default name CYGNUS2.ISC. The configuration file can be named within the eight-character limitation that exists in the USB file handling firmware.
DD = day of month, MM = month, YY = year, C# represents the Material# where # is from 1 to 6. If a file with the same name exists, the new data log information will be appended to the existing file. Cygnus 2 will use the .IDL extension to identify Datalog files. See Figure 12-2.
DD = day of month, MM = month, YY = year, xx is a number that increments from 0 to 99, resetting to 0 every day. Cygnus 2 will use the .BMP extension to identify screen capture files. The +++ indicates that additional files exist on the USB device beyond those displayed.

The Crystal Sensor Emulator option is used in conjunction with the Thin Film Deposition Controller to rapidly diagnose problems with the Deposition Controller's measurement system.
Cygnus 2 Operating Manual 13.8.1 Diagnostic Procedures The following diagnostic procedures employ the Crystal Sensor Emulator to analyze a constant Crystal Fail message. The symptom is a Crystal Fail message that is displayed by the Deposition Controller even after the monitor crystal has been replaced with a new good monitor crystal.
Cygnus 2 Operating Manual 13.8.1.2 Feedthrough Or In-Vacuum Cable Diagnostic Procedure Refer to Figure 13-8 on page 13-26. Remove the in-vacuum cable from the Sensor Head at point B. Connect the Crystal Sensor Emulator to the in-vacuum cable. If the Crystal Fail message disappears after approximately five seconds, the feedthrough and in-vacuum cable are working properly.
There must be electrical isolation between the center pin of the Microdot connector and the Sensor Head body. If the Sensor Head is found to be defective, contact INFICON to have the Sensor Head repaired—refer to section 1.3 on page 1-5.

Cygnus 2 Operating Manual Chapter 14 Measurement and Control Theory 14.1 Basics The Quartz Crystal deposition Monitor, or QCM, utilizes the piezoelectric sensitivity of a quartz monitor crystal to added mass. The QCM uses this mass sensitivity to control the deposition rate and final thickness of a vacuum deposition. When a voltage is applied across the faces of a properly shaped piezoelectric crystal, the crystal is distorted and changes shape in proportion to the applied voltage.
Cygnus 2 Operating Manual effect provides a means of determining how much material is being deposited on a substrate in a vacuum system, a measurement that was not convenient or practical prior to this understanding. 14.1.1 Monitor Crystals No matter how sophisticated the electronics surrounding it, the essential device of the deposition monitor is the quartz crystal.

Figure 14-5 Crystal frequency near series resonance point 14.1.5 ModeLock Oscillator INFICON created a new technology that eliminates the active oscillator and its limitations. This new system constantly tests the crystal’s response to an applied frequency in order to not only determine the resonant frequency, but also to verify that the crystal is oscillating in the desired mode.
Page 247
Cygnus 2 Operating Manual measurement system uses the phase/frequency properties of the quartz crystal to determine the resonant frequency. It operates by applying a synthesized sine wave of specific frequency to the crystal and measuring the phase difference between the applied signal’s voltage and the current passing through the crystal. At series resonance, this phase difference is exactly 0 degrees;...

Cygnus 2 Operating Manual assignment refer to the number of phase reversals in the wave motion along the three axes of the crystal. The above-referenced papers by Wilson and Tiersten & Smythe are examinations of modal properties, relating the various properties of the radius of curvature to the placement of the anharmonics relative to the fundamental.
Cygnus 2 Operating Manual Needless to say, similar errors occur with the Z-match™ technique under similar circumstances. However, the automatic Z-Ratio estimate is somewhat more prone to error, because the amplitude distribution of the mode [102] is asymmetric, whereas that of the mode [100] is symmetric over the active area of the crystal.
