Abstract

PURPOSE:To eliminate the need for occupying area for forming a contacting section by a method wherein a semiconductor layer made up on a semiconductor substrate through an insulating film with an opening is annealed by lasers or electron beams, the semiconductor layer of the opening section is changed into a single crystal and an element is manufactured. CONSTITUTION:An insulating film 2 with an opening is made up on a semiconductor substrate 1, the film 2 is coated with a polycrystal or amorphous Si, an Si layer of the opening section is changed into a single crystal by annealing by lasers or electron beams, B, etc. are diffused and a base region 7 and a P type polycrystal Si layer 6 are built up, P, etc. are introduced and an N type emitter region 10 is formed, the polycrystal Si layer 6 is used as a wiring conductor as it is, and wiring bodies 11, 11' are made up. Thus, occupying area for forming a contacting section of an electrode and positioning allowance are not required, and high density is obtd.
