Abstract

1,273,199. Semi-conductor devices. HITACHI Ltd. 17 Oct., 1969 [21 Oct., 1968 (2)], No. 51239/69. Heading H1K. A method of manufacturing transistors comprises preparing a high resistivity, e.g. 10 # cm., N-type, silicon substrate 11, and diffusing into it, either from the gas phase or from a coating on the surface, an N-type impurity, e.g. phosphorus, to form a shallow, heavily doped region; a drive in step at 1200‹ C. in a nitrogen atmosphere follows to form an N<SP>+</SP> region 13 with an impurity concentration of 10<SP>20</SP> atoms/c.c.; the other surface is exposed and a diffusion of a P- type impurity, e.g. boron, takes place to form a base region 14; another N-type diffusion follows to form a plurality of emitter regions 15; contact is made to the regions, the collector region comprising a part of the original substrate 11, and the region 13; and the substrate is divided up by slots 19 to form a plurality of transistors. Grown oxide layers may be used as masking material. A substrate of P or I type material alternatively may be used.
