Abstract

We introduce a new procedure to perform a design of experiments (DOE) for plasma etching processes. In particular, we use in situ etch rate estimations to maximize the number of observable setpoints during a single run of the etching process. This procedure is applied to characterize the spatial uniformity of a plasma chamber used in the manufacturing of flat panel displays.
