Plasma ashing process for removing photoresist and residues during ferroelectric device fabrication

摘要

A low temperature plasma ashing process for use with substrates comprising a ferroelectric material. The process generally includes plasma ashing the photoresist and residues at a temperature of about room temperature to about 140° C., wherein the plasma is generated from a gas mixture consisting essentially of hydrogen and an inert gas, and wherein the ferroelectric material is exposed to the plasma.
