摘要:
The present invention provides a method for manufacturing a semiconductor device and method for manufacturing an integrated circuit including the semiconductor device. The method for manufacturing a semiconductor device (100), among other steps, includes forming a gate structure (130) over a substrate (110), the gate structure (130) having sidewall spacers (210 or 410) on opposing sidewalls thereof and placing source/drain implants (310, 510) into the substrate (110) proximate the gate structure (130). The method further includes removing at least a portion of the sidewall spacers (210 or 410) and annealing the source/drain implants (310, 510) to form source/drain regions (710) after removing the at least a portion of the sidewall spacers (210 or 410).
