    摘要: Bi-directional back-to-back stacked SCRs for high-voltage pin ESD protection, methods of manufacture and design structures are provided. The device includes a symmetrical bi-directional back-to-back stacked silicon controlled rectifier (SCR). An anode of a first of the back-to-back stacked SCR is connected to an input. An anode of a second of the back-to-back stacked SCR is connected to ground. Cathodes of the first and second of the back-to-back stacked SCR are connected together. Each of the symmetrical bi-directional back-to-back SCRs include a pair of diodes directing current towards the cathodes which, upon application of a voltage, become reverse biased effectively and deactivating elements from one of the symmetrical bi-directional back-to-back SCRs while the diodes of another of the symmetrical bi-directional back-to-back SCRs direct current in the same direction as the reverse biased diodes.

    摘要: Back gate triggered silicon controlled rectifiers (SCR) and methods of manufacture are disclosed. The method includes forming a first diffusion type and a second diffusion type in a semiconductor layer of a silicon on insulator (SOI) substrate. The method further includes forming a back gate of a first diffusion type in a substrate under an insulator layer of the SOI substrate. The method further includes forming raised diffusion regions of a first dopant type and a second dopant type, adjacent to the second diffusion type and the first diffusion type, respectively. The back gate is formed to cover the second diffusion type, the first diffusion type and the second dopant type of the raised diffusion regions.
