ABSTRACT:
A method of fabricating polysilicon patterns. The method includes depositing polysilicon on a substrate. The polysilicon may be doped or pre-doped depending upon the application. A mask layer is applied and patterned. Thereafter, the polysilicon is etched to form the polysilicon patterns and an oxidizing step is performed. The mask layer is removed after the oxidizing step is performed.
