Abstract

1,205,320. Semi-conductor devices. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP. 25 Oct., 1968 [28 Oct., 1967], No. 50752/68. Heading H1K. A method of producing a mesa type semiconductor element structure, wherein the sides of the mesa are covered with an insulating layer, comprises forming on that part of the surface of the semi-conductor element where the mesa is required a layer 3 of nitride and then oxidizing the remainder of the surface of the element to a depth H such that after the nitride layer 3 is removed to expose the semi-conductor surface the oxide layer 4 still remains over the rest of the surface to leave a mesa of height h whose side walls are protected by the oxide. A PN junction can then be formed in this mesa and a metal contact deposited on its top surface. The semi-conductor material may be silicon, germanium or gallium arsenide, and the nitride layer may be silicon nitride or tantalum nitride. In a further embodiment of the method, where accurately formed hollows are required in a silicon crystal surface, a silicon nitride mask is applied on the surface and apertures formed where the hollows are required. The silicon is then oxidized over these exposed regions into the crystal and then selectively removed to leave the required hollows. The nitride layers are grown from gases and the oxide layers by oxidation, and both are removed by etching processes. The method may be applied in the production of diodes, or transistors of the planar type
