Hl. Maynard et N. Hershkowitz, NEW ALTERNATIVE GRAPHING METHODS FOR THIN-FILM INTERFEROMETRY DATA, IEEE transactions on semiconductor manufacturing, 6(4), 1993, pp. 373-377
Thin-film interferometry has long been used to monitor deposition and
etching processes. This paper presents Lissajous and phase-space graph
s of thin-film interferometry traces and discusses some of the practic
al implications of graphing the data in these non-traditional formats.
These types of graphs can highlight certain process events and provid
e a more user-friendly operator interface for the control of thin-film
etching and deposition processes.
