Abstract
The present invention provides a method for manufacturing a semiconductor structure, which comprises: a) forming gate lines extending along one direction on a substrate; b) forming a photoresist layer that covers the semiconductor structure; patterning the photoresist layer to form openings that span over the gate lines: c) implanting ions into the gate lines, such that the gate lines are insulated at the openings. The present invention enables the gate lines to maintain complete shape at formation of electrically isolated gates, which will not cause defects that exist in the prior art when forming a dielectric layers at subsequent steps, thereby guaranteeing performance of semiconductor devices. Additionally, the present invention further provides a semiconductor structure manufactured according to the method provided by the present invention.
