Abstract
PURPOSE:To improve yield on manufacture by a method wherein a base region and an insulating film are formed onto a semiconductor substrate, a mask with first and second opening sections is shaped onto the insulating film, the ions of an impurity are implanted obliquely, the insulating film is etched and an emitter contact and a base contact are formed. CONSTITUTION:A p<-> type base region 12 and an insulating film 13 are formed onto an n<-> type epitaxial layer 11 constituting a semiconductor substrate in succession. A photo-resist film 14 is shaped onto the insulating film 13 and patterned, and a first opening section 15 for an emitter contact and a second opening section 16 for a base contact are formed. Boron ions 17 are implanted to the semiconductor substrate from the direction opposite to the first opening section 15 to the second opening section 16, using the photo-resist film 14 as a mask, and a p<+> type graft base region 18 is shaped into the base region 12. The insulating film 13 is etched, employing the photo-resist film 14 as a mask, thus forming an emitter contact 15A and a base contact 16A. Accordingly, the yield in manufacture can be improved.
