Patent ID: 8135560

Claim:
A system for monitoring the rotation of substrate supports in substrate processing chambers, comprising: a first rotating substrate support positioned in a first processing chamber; a second rotating substrate support positioned in a second processing chamber; a first sensor monitoring the first rotating substrate support; a second sensor monitoring the second rotating substrate support; a first sensor line coupling the first sensor to a first chamber board; a second sensor line coupling the second sensor to a second chamber board; a central control unit coupled to the first sensor line and the second sensor line, the central control unit processing first rotation data associated with the first rotating substrate support and second rotation data associated with the second rotating substrate support and determining rotation rates associated with the first and second rotating substrate supports; and one or more remote control systems connected to the central control unit, the one or more remote control systems receiving the first rotation data and the second rotation data from the central control unit, wherein the one or more remote control system transmits control parameters to the central control unit.
