Abstract:
This paper discusses the removal of the doped-polysilicon of a gate transistor by wet chemical etching containing the spacer oxide and nitride that remain. This technique significantly improves the image quality of 2-D doping profile of SCM that properly provides the results of the desired device structures for inline monitoring and failure analysis or for product characterization.
