METHOD FOR CO-FABRICATING STRAINED AND RELAXED CRYSTALLINE AND POLY-CRYSTALLINE STRUCTURES

摘要

One embodiment of the present invention provides a system for co fabricating strained and relaxed crystalline, poly-crystalline, and amorphous structures in an integrated circuit device using common fabrication steps. The system operates by first receiving a substrate. The system then fabricates multiple layers on this substrate. A layer within these multiple layers includes both strained structures and relaxed structures. These strained structures and relaxed structures are fabricated simultaneously using common fabrication steps.
