Title: Preparation of semiconductor device
Inventor: HIRAO TADASHI
IPC: H01L21/331
Filed: 1978-12-06
Abstract: PURPOSE: To improve integration degree and frequency characteristic by making a two-step structure separation film and reducing a distance between emitter layer and separation film oxide.  
     CONSTITUTION: An n + -buried layer is formed in a p-type Si substrate 1, an n- epitaxial layer 3 is laminated, SiO 2  film 10, Si 3 N 4  film 20 are laminated and an opening is made with a mask of a resist 30. After selectively etching Si 3 N 4  film 20 the n-layer is etched removing the mask. Next a deep separation film 11, which reaches the collector buried layer is formed by means of selective oxidation. Further normally an npn-transistor is prepared. As a result thereof the prepared film 11 is of two-step constitution: one part 11 reaching the buried layer 2 and the other part 12 surrounding the emitter layer in the periphery of the former to reduce the leak generating rate between collector and emitter as well as a distance between the edge of emitter layer and the separation film thus improving frequency characteristic. Also the resulting reduced base area serves to lower collector-base capacity and to improve frequency characteristic.
