    • A Zener diode comprising a semiconductor substrate having an n-type region partly exposed at a main force of the substrate, a p.sup.+ -type region disposed contiguous to the n-type region and exposed at the main face of the semiconductor substrate, and an n.sup.+ -type region also exposed at the main face of the substrate and contiguously surrounded by the p.sup.+ -type region besides being contiguous to the p.sup.+ -type region. The arrangement of the semiconductor regions in relation to one another, and an an insulating layer on the main face of the substrate and to a pair of electrodes thereon, is such that the breakdown voltage is free from the influence of temperatures and of the ions contained in the insulating layer.
    • 一种齐纳二极管,包括:半导体衬底,其具有以衬底的主力部分地暴露的n型区域,与所述n型区域邻接并暴露在所述半导体衬底的主面处的p +型区域,以及n + 型区域也暴露在基板的主面上,并连续地被p +型区域包围,除了与p +型区域相邻。 半导体区域相对于彼此的布置,以及基板的主面上的绝缘层和其上的一对电极,使得击穿电压不受温度和所含离子的影响 在绝缘层中。
