    摘要: Semiconductor-on-insulator device structures with enhanced electrostatic discharge protection, and design structures for an integrated circuit with device structures exhibiting enhanced electrostatic discharge protection. A device is formed in a body region of a device layer of a semiconductor-on-insulator substrate, which is bounded by an inner peripheral sidewall of an annular dielectric-filled isolation structure that extends from a top surface of the device layer to the insulating layer of the semiconductor-on-insulator substrate. An annular conductive interconnect extends through the body region and the insulating layer to connect the body region with the bulk wafer of the semiconductor-on-insulator substrate. The annular conductive interconnect is disposed inside the inner peripheral sidewall of the isolation structure, which annularly encircles the body region.

    摘要: A Silicon on Insulator (SOI) Integrated Circuit (IC) chip with devices such as a vertical Silicon Controlled Rectifier (SCR), vertical bipolar transistors, a vertical capacitor, a resistor and/or a vertical pinch resistor and method of making the device(s). The devices are formed in a seed hole through the SOI surface layer and insulator layer to the substrate. A buried diffusion, e.g., N-type, is formed through the seed hole in the substrate. A doped epitaxial layer is formed on the buried diffusion and may include multiple doped layers, e.g., a P-type layer and an N-type layer. Polysilicon, e.g., P-type, may be formed on the doped epitaxial layer. Contacts to the buried diffusion are formed in a contact liner.
