Abstract

An algorithm for end-point detection is described in the IBM Technical Disclosure Bulletin 20, 113-138 (June 1977). Described herein is an algorithm which makes it possible to quench a quartz via etch process at a precise time, which leaves the required amount of quartz at an endpoint detect test site.
