FIELD: semiconductor devices. SUBSTANCE: one emitter region is placed on each radial direction in symmetry relative to region positioned centrally. One contact to base region is arranged between contacts to emitter regions. Contacts to collector region are placed over periphery of collector region in symmetry at certain distance from each other and from base region. EFFECT: improved capability of parameter programming. 2 cl, 2 dwg, 2 tbl
