    摘要: An electrical structure and method of forming. The method includes providing a semiconductor structure comprising a semiconductor substrate, a buried oxide layer (BOX) formed over the semiconductor substrate, and a silicon on insulator layer (SOI) formed over and in contact with the BOX layer. The SOI layer comprises shallow trench isolation (STI) structures formed between electrical devices. A first photoresist layer is formed over the STI structures and the electrical devices. Portions of said first photoresist layer, portions of the STI structures, and portions of the BOX layer are removed resulting in formed trenches. Ion implants are formed within portions of the semiconductor substrate. Remaining portions of the first photoresist layer are removed. A dielectric layer is formed over the electrical devices and within the trenches. A second photoresist layer is formed over the dielectric layer. Portions of the second photoresist layer are removed.

    摘要: A backside contact structure and method of fabricating the structure. The method includes: forming a dielectric isolation in a substrate, the substrate having a frontside and an opposing backside; forming a first dielectric layer on the frontside of the substrate; forming a trench in the first dielectric layer, the trench aligned over and within a perimeter of the dielectric isolation and extending to the dielectric isolation; extending the trench formed in the first dielectric layer through the dielectric isolation and into the substrate to a depth less than a thickness of the substrate; filling the trench and co-planarizing a top surface of the trench with a top surface of the first dielectric layer to form an electrically conductive through via; and thinning the substrate from a backside of the substrate to expose the through via.

    摘要: Bipolar transistor structures, methods of designing and fabricating bipolar transistors, methods of designing circuits having bipolar transistors. The method of designing the bipolar transistor includes: selecting an initial design of a bipolar transistor; scaling the initial design of the bipolar transistor to generate a scaled design of the bipolar transistor; determining if stress compensation of the scaled design of the bipolar transistor is required based on dimensions of an emitter of the bipolar transistor after the scaling; and if stress compensation of the scaled design of the bipolar transistor is required then adjusting a layout of a trench isolation layout level of the scaled design relative to a layout of an emitter layout level of the scaled design to generate a stress compensated scaled design of the bipolar transistor.
