Abstract: PURPOSE: To reduce the chip size by securing a perfect self-matching structure.  
     CONSTITUTION: P-epitaxial layer 7 is provided to P-type substrate 1 to which N +  buried layer 2 is formed and then covered with Si 3 N 4  film 10 after forming Si 3 N 4   film 9 selectively on SiO 2  film 8. Film 10 and 8 plus the exposed substrate are etched via resist mask 15. Then mask 15 is removed to then remove film 10, and P +  is  diffused to exposed parts A∼D via mask 9 to form heat oxide film 11. Thus, film  11a, 11c and 11d are mode to reach the buried layer. After this, film 9 and 8 are  removed entirely, and the concave areas of film 11 are etched to be smoothed.  Then n +  collector layer 14 and n +  emitter layer 13 are selectively formed. In this  way, the lateral direction between the base and emitter fearures the self-matching  structure, thus omitting the mask matching margin and thus reducing the chip size.  Furthermore, the pn-junction capacity is eliminated to esnure a high-speed sction  since the active region and the emitter layer of the base are partitioned by the oxide  film
