Plasma etch movable substrate
First Claim
1. An apparatus for the manufacturing of semiconductor devices from semiconductor wafers having a plurality of semiconductor circuit patterns on at least a reacting surface of the semiconductor wafer, the apparatus comprises:
- reacting means for providing a stream of reacting gases to react with the semiconductor wafer to create circuit elements according to the semiconductor circuit pattern thereby;
handling means for handling the wafers and includes a chamber means for bringing the wafers into contact with the reacting gas, and the chamber means includes a plasma means for generating a plasma, and means for varying the volume of the chamber means;
degassing means for degassing of the semiconductor wafers, port means for preventing the contamination of the chamber means and to provide a port for the transfer of the semiconductor wafers from the degassing means to the chamber means;
exit means for isolating the semiconductor wafers and the circuit elements from the chamber means, second port means for providing a port for the transfer of the semiconductor wafer between the chamber means and the exit means, and transfer means for transferring the semiconductor wafer from the degassing means to the chamber means and from the chamber means to the exit means; and
ninth means for controlling the operation of the apparatus.

Abstract
A substrate that is a portion of an electrode of a plasma reactor has two positions, a low position and a process position. They are achieved without generating particulate contaminate and are achieved additionally while the reaction chamber is maintained at its process pressure.
Stainless steel bellows assemblies have an inter volume that are capped at both ends from a chamber between the bellows. One end of the bellows assembly is mounted to the process chamber in a fixed position and a substrate to the other end is attached and is movable. A positioning is achieved by introducing compressed air in the chamber between the bellows and overcoming the process pressure in the outer chamber. A second position is achieved by releasing the compressed air between the chamber between the bellows and allowing the process pressure in the process chamber to collapse the bellows assembly.
