Method and system for sequential processing in a two-compartment chamber
First Claim
1. A method for sequentially processing a plurality of workpieces, the method comprising the steps of:
- a) processing a first plurality of workpieces on a workpiece mover in a first compartment and a second plurality of workpieces on the workpiece mover in a second compartment;
b) rotating the workpieces on the workpiece mover between the first and second compartments through a plurality of internal pathways, the first and second compartments being isolated from each other by a plurality of pathway doors coupled to the workpiece mover, with said pathway doors closing the internal pathways at a first side;
c) processing the first plurality of workpieces in the second compartment and the second plurality of workpieces in the first compartment; and
d) rotating back the workpieces on the workpiece mover between the first and second compartments through the internal pathways, the first and second compartments being isolated from each other by the pathway doors, with said pathway doors closing the internal pathways at a second side.

Abstract
An apparatus and method for sequential and isolated processing of a workpiece comprises a two compartment chamber and a mechanism to transfer the workpiece from a fist compartment to a second compartment by rotating the workpiece on a workpiece mover through an internal pathway. The transfer mechanism comprises two doors coupled to the workpiece mover to seal the internal pathway between the first and second compartments so that the two compartments are isolated and the workpiece can be processed sequentially and in isolation. The apparatus further comprises components to enable the processing of a workpiece. The preferred method of processing a workpiece is to deposit or adsorb a thin layer in the first compartment and then transfer by rotating the workpiece on the workpiece mover to the second compartment for further processing. The workpiece can then be transferred once again to the first compartment for further processing, and again to the second compartment, repeating the processing and transferring steps until a desired thin film is achieved.
