Abstract:
1. A method for fabricating a semiconductor device comprising the steps of: (a) forming a compound layer including a semiconductor element and a nonmetal element on a semiconductor layer; (b) distributing said nonmetal element included in said compound layer in the region in the vicinity of the surface portion of said semiconductor layer through recoil by irradiating said compound layer with a particle energy beam; (c) after the step (b), removing said compound layer; (d) after the step (c), depositing a metal film on said semiconductor layer; and (e) after the step (d), epitaxially growing a semiconductor-metal compound layer in the surface portion of said semiconductor layer by causing a reaction between an element included in said semiconductor layer and a metal included in said metal film through annealing carried out on said metal film, wherein said region in the vicinity of the surface portion of said semiconductor layer is within a depth of 0.5 nm to 5 nm from the surface of the semiconductor layer, and a dosage of said nonmetal element per unit area is between 4×10
