ISOLATED TRANSISTORS AND DIODES AND ISOLATION AND TERMINATION STRUCTURES FOR SEMICONDUCTOR DIE |
摘要 |
Various integrated circuit devices, in particular a transistor, are formed inside an isolation structure which includes a floor isolation region and a trench extending from the surface of the substrate to the floor isolation region. The trench may be filled with a dielectric material or may have a conductive material in a central portion with a dielectric layer lining the walls of the trench. Various techniques for terminating the isolation structure by extending the floor isolation region beyond the trench, using a guard ring, and a forming a drift region are described. |
