Claim 0:
1. A semiconductor structure comprising:
a substrate, including a base and a plurality of fins discretely formed over the base, wherein each fin is made of a material including a first atom and contains openings therein; and
a source-drain doped layer, located in each opening and including a seed layer on a surface of an inner wall of the opening and a body layer on a surface of the seed layer, a material of the seed layer including the first atom, a second atom, and a third atom, and a material of the body layer including the first atom and the second atom but not including the third atom, the third atom including a germanium atom;
wherein a concentration percentage of the germanium atom respect to a total amount of atoms of the source-drain doped layer ranges from 5% to 10%.
