Abstract

Apparatus for mounting wafers in an epitaxial reactor is disclosed. The apparatus includes a wafer carrier for holding the wafer during the epitaxial deposition, including a depressed region for the wafer, and a positioning wire located in the depressed region to maintain the position of the wafer without interfering with the epitaxial deposition process itself.
