Filed: 1973-04-09
Abstract: 1394160 Integrated circuits RAYTHEON CO 9 April 1973 [26 April 1972] 16942/73 Heading H1K In the manufacture of an integrated circuit comprising semi-conductor elements formed in a semi-conductor layer on a semi-conductor substrate of the opposite conductivity type and mutually isolated by isolation regions (e.g. grooves) extending through the layer into the substrate, the formation of the layer and of the isolation regions is carried out below the plasticity temperature of the semi-conductor layer (1050‹ C. for silicon). A typical method of making a circuit comprises first forming N type subcollector regions 11 in a 100 face of a 1 ohm. cm. P type silicon wafer 10 by masked diffusion of deposited antimony and then depositing silicon at 1010‹ C. from a mixture of silane and arsine to a depth of 2À5 Á. Base regions 1 Á deep are next formed by oxide masked diffusion from boron tribromide at 1000‹ C. under oxidizing conditions. Triangular section isolation grooves extending into the substrate are etched through apertures in an oxide coating the straight sides of which are parallel to 111 axes using sodium or potassium hydroxide or an organic solution. After removing the oxide 500 A of silica, 1500 Š of silicon nitride and 8000 Š of silica are deposited at less than 1000‹ C., suitable apertures formed therein, and phosphorus diffused in at 970‹ C., if desired after etching to expose part of the subcollector regions, to form emitter regions and collector contact regions. After exposing part of the base region and reopening the previously formed apertures by sputter etching using a titanium electrode, the wafer is dipped in hydrofluoric acid to remove traces of titanium. Then after a further period of sputter etching with an inert electrode platinum is sputter deposited and heated to form platinum silicide on the contact regions. Conventional metallization is then carried out. The process may be adapted to form the memory cells described in Specification 1,383,893.
