This parameter provides the time value when the map parameter Indexer Synchronization Mode is

set to DELAY. The indexer allowed a predetermined pocket search time. This is a parameter with global
scope.???

Parameter

CH

ANNEL

x START MODE

[where x = any of 1 through 8]

Channel Start Mode: Off, Active, Standby

Units

None

Channel x Start Mode

This indicates which of the crystal sensor channels will be active when a deposition run starts.

Unless the crystal fails, or an I/O program processing event causes a configuration change, this crystal state
will remain in effect throughout the process.

Parameter

CH

ANNEL

x FAIL ACTION

[where x = any of 1 through 8]

Channel Fail Action: None, Abort Film

Units

None

Channel x Fail Action

This indicates what will occur when a channel fails for whatever reason. NONE provides no fail

action. Abort Film provides a film abort when a failure occurs on this channel.

BACKUP

LIST

[where

x = any of 1 through 8]

Channel Backup List: Z – ZZZZZZZZ (1 item list to 8 item list)
[where Z = 1 to 8 (in each position w/o redundancies, list extends to 0-8 for a 1 item list)]

Units

None

Channel x Fail Action

This parameter provides a list of potential backup crystal sensors should this channel fail for

whatever reason. The crystal sensor channel switching is automatic when there is a sensor failure.
Thickness and rate control is maintained during the switching operation. Also, for those multiple material
depositions requiring extreme accuracy of measurement that mixing of materials on one sensor could
degrade, it is possible to use a specific sensor for each material type.
Example backup lists:

comments:

0

(zero) no backups are defined

3

channel 3 is the one and only backup channel

237

backup channels are 2 then 3 then 7

2345678

backup channels are sequentially: 2345678

235637

incorrect list: 3 is repeated

x TOOLING

[where x = any of 1 through 8]

Tooling Value: RANGE IS 10.0 - 400.0

Units

Percent

Channel x Tooling

This TOOLING parameter is used in conjunction with the MASTER TOOLING parameter as a

correction factor to compensate for geometric position differences between the location of the sensor and
the target substrate. All of the 8 possible sensors have their own tooling factor. If no correction is required,
both the substrate and sensor see the material source in an identical manner and the Tooling Parameter is
set to 100%. Generally, if the sensor is farther from the source than the substrate, the tooling will be set to
>100%. If the sensor is closer to the source, the tooling will be set to < 100%. See Section x4.2 for
calibration information.

x WEIGHT

[where x = any of 1 through 8]

Weight Value: RANGE IS 10.0 - 400.0

Units

Percent

Channel x Weight

This parameter is used during a multi-sensor averaging process. Programming 2 or more crystal

sensor channels as active automatically invokes an averaging mode. Weight provides the user with a
method to assign each of the sensors a contribution percentage of the total used to determine thickness.
When not in averaging mode, this parameter has no effect.
