Abstract
Methods for forming self-aligned photosensitive material spacers about protruding structures in semiconductor devices. One embodiment of the invention is a method for forming a LDD structure, utilizing disposable photosensitive material spacers. A second embodiment of the invention includes a method for forming a transistor, having salicided source/drain regions, utilizing photosensitive polyimide spacers for forming the salicided source/drain regions, without disposing of the spacers. A third embodiment of the invention includes a method for creating an offset from a protruding structure on a semiconductor substrate, using disposable photosensitive material spacers.
