Semiconductor device and method of manufacturing the same

A method of manufacturing a semiconductor device comprising:

• (a) applying a first raw material gas to a surface of a Si substrate of n-conductive type while the substrate is heated in a vacuum container to form a first Si film of n-conductive type on the substrate;
• (b) applying a second raw material gas to a surface of the first n-conductive type Si film under heating to form a SiGe film of p-conductive type on the first Si film;
• (c) applying a third raw material gas to a surface of the SiGe film of p-conductive type under heating to form a second Si film of p-conductive type on the SiGe film;
• (d) applying a fourth raw material gas to a surface of the second Si film under heating to form a third Si film of n-conductive type on the second Si film of p-conductive type;
• (e) implanting a high concentration of phosphorus ion to a surface layer portion of the third Si film of n-conductive type and annealing the surface layer portion to activate the phosphorus ion implanted;
• (f) removing a part of the third Si film due to expose the second Si film or changing the conductive type of a part of third Si film to another conductive type;
• and
• (g) joining a metal terminal to a part of the second Si film exposed by removing the third Si film or the part of the third Si film of another conductive type to form a first electrode, joining a metal terminal to the third Si film to form a second electrode, and joining a metal terminal on a back surface of the Si substrate of n-conductive type to form a third electrode.
