Classification: CPC H  C | IPC C  H

Claim 16:
17. A system for reducing particle accumulation on a semiconductor substrate during processing of the semiconductor substrate in a material deposition processing tool, the system comprising:
a plurality of processing stations;
a spindle mechanism including a fluid actuated cylinder and an electric driven motor;
a plurality of carrier rings, each carrier ring configured to receive a semiconductor substrate, the carrier rings mechanically cooperating with the spindle mechanism to raise or lower the carrier rings at a station of the plurality of stations or to rotate the carrier rings from one station of the plurality of stations to another station of the plurality of stations; and
one or more sensor selected from:
a sensor to detect pressure of fluid to be delivered to the fluid actuated cylinder, a sensor to detect pressure of fluid within the fluid actuated cylinder, a sensor to detect electric current received by the electric driven motor, a sensor to detect a period of time needed to raise, lower or raise and lower one of the plurality of carrier rings, and a sensor to detect vibration of the spindle mechanism.
