Optical end point detection of etched YBCO films

  • 1. Inst. fuer Electrotechnische Grundlagen der Informatik, Univ. Karlsruhe (Germany)

Description

A simple end point detection method for dry etching of YBCO layers on uniform substrates is presented. Reflectivity measurements of the etched layer with a He-Ne laser beam provides process control and end point detection. A possible application of this method to YBCO layers on substrates with buffer layers is discussed. (orig.)
