Filed: 1979-08-29
Abstract: PURPOSE:To eliminate breakage of metal by evaporating a part of metals coated on the bottom surfaces of windows to adhere again on the thin metal on the side surface when an oxidized film is applied on a semiconductor substrate formed in the element region, windows are opened and an electrode metal contacting a predetermined region is coated. CONSTITUTION:A base region 13 is diffused and formed on an Si substrate 14 which becomes a collector region, an emitter region 12 is provided in the base region 13, and is covered with an SiO2 film 11 to correspond to the regions 12 and 13 to open the window for adhering to electrode metals 15. Then, while electrode metals 15 contacting these regions 12 and 13 are applied thereon, only this metals 15 adhere to the side walls of the windows even if they are applied thickly on the upper surfaces of the films 11 and the bottom surfaces of the windows. Accordingly, radiations 17 such as laser light, electron beams, particle beams and the like are applied to the metals 15 at the bottom surfaces of the windows to evaporate them and cause them to adhere again to the thin metals at the window side walls to increase the thickness of these parts. Thereafter, a photoresist 16 for patterning is used to perform etching, thereby metals 15 having substantially the same thickness remains within the window and peripheral parts.
