Apparatus and method for supporting, positioning and rotating a substrate in a processing chamber

Abstract

Embodiments of the invention contemplate a method, apparatus and system that are used to support, position, and rotate a substrate during processing. Embodiments of the invention may also include a method of controlling the transfer of heat between a substrate and substrate support positioned in a processing chamber. The apparatus and methods described herein remove the need for complex, costly and often unreliable components that would be required to accurately position and rotate a substrate during one or more processing steps, such as an rapid thermal processing (RTP) process, a chemical vapor deposition (CVD) process, a physical vapor deposition (PVD) process, atomic layer deposition (ALD) process, dry etching process, wet clean, and / or laser annealing process.

Description

technical field [0001] The present invention relates generally to the field of semiconductor processing, and more particularly to apparatus and methods for supporting, positioning or rotating substrates in processing chambers during the production of semiconductor devices. Background technique [0002] In integrated circuit and display production, semiconductor, dielectric and conductive materials are formed on substrates such as silicon or glass. Materials can be formed using chemical vapor deposition (CVD), atomic layer deposition (ALD), physical vapor deposition (PVD), ion implantation, plasma or thermal oxidation and nitridation processes. The deposited material is then etched to form features such as gates, vias, contacts, and interconnects. In a typical deposition or etch process, a substrate is exposed to a plasma in a substrate processing chamber to deposit or etch material on the surface of the substrate. Other typical processes performed on the substrate include ...
