IQM-233 Operating Manual

Sif142Simulate (long Mode)

Sets the operating mode. Normal mode requires the IQM-233 card(s), sensors,
and a source power supply for proper operation. In simulate mode, no IQM-233
card is required. The DLL simulates the frequency readings and power output
required for PID loop control. The initial sensor frequency is fixed at 5.95 MHz
and approximately 50% output power is required to start simulating deposition.

Mode . . . . . . . . . . . . . . . . . . . . . 1 turns on simulate mode

0 turns on normal mode

Sif142StartMeas ()

Starts the card measuring frequency and zeros the sensor thickness reading.

Sif142ZeroSensor (long SensorNum)

Sets a sensor (0 to 23) thickness reading to zero.

Sif142Zero2 (long OutputNum)

Sets a control output (0 to 17) thickness reading for each assigned sensor to
zero.

Sif142Material (long Sensor, double Density, double
Zfact, double Tooling)

Sets up the material-specific parameters for each sensor.

Sensor . . . . . . . . . . . . . . . . . . . . A bit-weighted value for sensor(s). The three

lowest bits determine the selected sensor(s).
Add the bits to select multiple sensors, for
example, send 111 to select all three
sensors.
001 = Sensor 1
010 = Sensor 2
100 = Sensor 3

Density. . . . . . . . . . . . . . . . . . . . Sets the density of the material. Values are

from 0.4 to 99.99 g/cm

3

. Refer to

Appendix

A, Material Table

.

Zfact . . . . . . . . . . . . . . . . . . . . . . Z-Ratio (Z-Factor) of the material. This

number has no units, and can be found in

Appendix A, Material Table

. Values are from

0.100 to 9.999.

Tooling. . . . . . . . . . . . . . . . . . . . Accounts for the difference in deposition rate

at the sensor vs. the substrate. Values are a
range from 0 to 9.99, representing 0 to 999%.
