    • A semiconductor layout structure for an electrostatic discharge (ESD) protection circuit is disclosed. The semiconductor layout structure includes a first area, in which one or more devices are constructed for functioning as a silicon controlled rectifier, and a second area, in which at least one device is constructed for functioning as a trigger source that provides a triggering current to trigger the silicon controlled rectifier for dissipating ESD charges during an ESD event. The first area and the second area are placed adjacent to one another without having a resistance area physically interposed or electrically connected therebetween, such that the triggering current received by the silicon controlled rectifier is increased during the ESD event.
    • 公开了一种用于静电放电(ESD)保护电路的半导体布局结构。 半导体布局结构包括第一区域,其中构造一个或多个器件用作可控硅整流器,以及第二区域,其中构造至少一个器件用作触发源,该触发源提供触发电流 触发可控硅整流器,以在ESD事件期间耗散ESD电荷。 第一区域和第二区域彼此相邻放置,而不会在其间物理地插入或电连接电阻区域,使得在ESD事件期间由可控硅整流器接收的触发电流增加。

    • A process for fabricating a BiCMOS device, on a semiconductor substrate, featuring PFET and NFET devices, and an NPN bipolar junction transistor, has been developed. The process features the integration, or the sharing of process steps, used for both the CMOS and bipolar devices, such as the creation of an N type buried layer, used in one region for isolation of PFET devices, and used in a second region, of the semiconductor substrate, as a subcollector region, for the bipolar device. Features of the BiCMOS process include the formation of N well, and P well regions, for CMOS device, as well as the use of an epitaxial silicon layer, to allow optimum bipolar characteristics to be achieved.
