Abstract
A method for manufacturing a semiconductor structure is disclosed. The method comprises: providing an SOI substrate, which comprises, from top to bottom, an SOI layer (100), a BOX layer (110) and a base layer (130); forming a dummy gate stack on the SOI substrate and an implantation barrier layer on both sides of the dummy gate stack; removing the dummy gate stack to form a gate recess (220); and performing, via the gate recess (220), implantation of stress inducing ions to the semiconductor structure and annealing to form, right below the gate recess (220), a stress inducing region (150) under the BOX layer (110) of the SOI substrate. Accordingly, the present invention further provides a semiconductor structure manufactured according to the above method.
