Abstract

Some results of simultaneous measurement of polyimide etch rates, temperature, and O− and F− atom emission intensities in CF4/O2 plasma discharges are described. Several process variables have been investigated both during steady and unsteady plasma reactor operation. Atomic compositions on the polymer surface have been determined as a function of time of exposure to the plasma using ESCA, and the C IS spectra apalyzed to identify the various C-O and C-F bonds.
