Abstract
A method for manufacturing a semiconductor structure comprises following steps: providing an SOI substrate, forming a gate stack on the SOI substrate, forming sidewall spacers on sidewalls of the gate stack, and forming source/drain regions on each side of the gate stack; depositing a first metal layer on surfaces of an entire semiconductor structure, and then removing the first metal layer; forming an amorphous semiconductor layer on surfaces of the source/drain regions; depositing a second metal layer on surfaces of the entire semiconductor structure, and then removing the second metal layer; and annealing the semiconductor structure. Accordingly, the present invention further provides a semiconductor structure. The present invention is capable of effectively reducing contact resistance at source/drain regions.
