Parameter 20

Rate Ramp Time

access:

RRTM rate ramp time

Value Range

0:00 - 99:59

Units

Min:Sec

This parameter sets the duration of the rate ramp. The rate ramp starts at the rate control
value at the time that the rate ramp trigger is reached and ends at the value set by the new
Dep rate parameter.

Parameter 21

Rate Ramp Trigger

access:

RRTG rate ramp thickness trigger

Value Range

0 - 999.999

Units

Kilo

angstroms

This parameter sets the trigger point for a rate ramp to begin during deposit.

Parameter 22

Ctl Loop -P-

access:

PROP control loop proportional term gain

Value Range

1 - 9999

Units

None

This parameter sets the closed loop rate control proportional gain.

Parameter 23

Ctl Loop -I-

access:

INTG control loop integral term

Value Range

0.0 - 99.9

Units

Seconds

This parameter sets the closed loop rate control integral term time constant.

______________________________________________________________________

Parameter 24

Ctl Loop -D-

access:

DRIV control loop derivative term

Value Range

0.0 - 99.9

Units

Seconds

This parameter sets the closed loop rate control derivative term time constant.

______________________________________________________________________

Parameter 25

Max. Power Limit

access:

MAXP max power limit

Value Range

0.0 - 100.0

Units

Percent

This parameter sets the absolute maximum power level that will be allowed to occur at
any time from the instrument (film dependent).

______________________________________________________________________

Parameter 26

Abort Max. Pwr Switch

access:

ABMP abort on max power on/off

Value Range

0,1

Units

0 is Off, 1 is On

This parameter is a switch value. When set to Off it has no effect on the deposition
sequence and the programming data window will not access the associated max. power
dwell parameter. When set to on a maximum power condition will be allowed for the
time duration set by the now accessible max. power dwell parameter and then the STC-
2000A will abort the deposition sequence and power will be set to zero.
