    • A bipolar transistor (1) comprising a subcollector layer (3), a collector layer (4, 5), a base layer (6) and an emitter layer (7) which are successively built up and having: the subcollector layer (3) formed with a projection (3A) and recesses (3B), an upper part above the projection constituting an intrinsic transistor region (1A) of the bipolar transistor; insulator layer (10) buried between the recesses of the subcollector layer and the collector layer (4); a boundary interface between the subcollector layer and the collector layer held between the insulator layers; the base layer (6) made of a single crystal layer and provided with a base electrode (12) on a region becoming an extrinsic base layer (6B) of the base layer; and the subcollector layer provided with a collector electrode (11). The bipolar transistor has advantages of its emitter made finer in width, a reduced parasitic capacitance between its base and collector and improved high-frequency characteristics.
    • 一种双极晶体管(1),包括分别集电极层(3),集电极层(4,5),基极层(6)和发射极层(7),它们被连续地构建并具有:子集电极层(3) 形成有突起(3A)和凹部(3B),在突出部上方的上部构成双极晶体管的本征晶体管区域(1A); 埋置在子集电极层的凹部和集电体层(4)之间的绝缘体层(10); 子集电极层和保持在绝缘体层之间的集电极层之间的边界界面; 所述基底层(6)由单晶层制成,并且在成为所述基底层的外在基底层(6B)的区域上设置有基极(12) 以及设置有集电极(11)的子集电极层。 双极晶体管的优点在于其发射极宽度较窄,其基极和集电极之间的寄生电容降低,并提高了高频特性。
