    摘要: An SiO.sub.2 insulating layer is formed on an Si substrate, and an Si.sub.3 N.sub.4 insulating layer is formed on the SiO.sub.2 layer. A notch is formed in the Si.sub.3 N.sub.4 layer using a resist film as a mask. The SiO.sub.2 layer is etched using the Si.sub.3 N.sub.4 layer as a mask, thereby forming an opening larger than the notch cut in the SiO.sub.2 layer. As a result, the Si.sub.3 N.sub.4 layer extends over the opening in an overhanging manner. When As.sup.+ ions are implanted in the periphery of the notch of the Si.sub.3 N.sub.4 layer, the ion-implanted portion of the Si.sub.3 N.sub.4 layer is arcuated toward the base region. When a metal such as Ti is deposited on the arcuated portion, the metal is also deposited on the arcuated portion and the portion of the emitter region matching with the notch, thereby forming an emitter electrode portion.

    摘要: A method of etching away a selected portion of silicon oxide from a body of silicon oxide and tapering the edge of the remaining silicon oxide that delineates the selected portion comprises the steps of (a) delineating the selected portion with a coating of a photoresist on a surface of the body, and (b) etching away the selected portion with a composite solution that contains both an etchant for the silicon oxide and a component for lifting only the edge of the photoresist from the interface between the photoresist and the silicon oxide at the delineation of the selected portion.
