Claim 0:
1. A method of manufacturing semiconductor structure, comprising:
providing a semiconductor substrate;
forming a contact structure on the semiconductor substrate, the contact structure having a first side and a second side opposite to the first side; and
forming a dielectric spacer adjacent to the contact structure and having a first concave surface;
forming a first conductive element on the semiconductor substrate, wherein the first conductive element is partially surrounded by the first concave surface of the dielectric spacer;
wherein forming the dielectric spacer comprises:
forming a first dielectric layer at the first side of the contact structure; and
forming a second dielectric layer on the first dielectric layer, wherein the second dielectric layer has a U-shape structure from a top view perspective.
