Title: Manufacture of semiconductor device
Inventor: SATO MASAHARU
IPC: H01L21/331
Filed: 1989-03-28
Abstract: PURPOSE:To form a microscopic emitter region without limited by photolithography technique by determining the width of the region according to an interval size between the side face of a laminated film and an insulating film and a thickness size of the insulating film of the side face. CONSTITUTION:First and second silicon nitride films 8, 9 are removed by etching, an epitaxial layer 3 of the part in contact with the film 9 is exposed, and boron is ion implanted into the exposed layer 3 to form a base region 12. Then, a third silicon nitride film 13 is formed on the whole surface, and the film 13 remains only on the sides of laminated films 6, 7 by anisotropically etching. After a second polycrystalline silicon film 14 is formed on the whole surface, arsenic is ion implanted to diffuse the arsenic from the film 14 into the region 12 to form an emitter region 15. Thus, the region 15 can be formed in width size obtained by subtracting the thickness of the film 13 formed on the side faces of the films 6, 7 from a predetermined interval, thereby miniaturizing the region 15.
