  • Patent number: 8428984
    Abstract: Described herein are methods and systems for SOA to SOI transformation. The transformation is performed by a transformation engine, driven by a transformation algorithm. A “used case database”, to provide the current know-how information for such transformations, and a “performance database”, to describe new hardware parts with more powerful metrics are incorporated into the transformation algorithm. In addition, a business engine supports the transformation engine with business analyzing features using a “business value database”.

  • Patent number: 8420495
    Abstract: This invention disclosed a manufacturing approach of collector and buried layer of a bipolar transistor. One aspect of the invention is that a pseudo buried layer, i.e, collector buried layer, is manufactured by ion implantation and thermal anneal. This pseudo buried layer has a small area, which makes deep trench isolation to divide pseudo buried layer unnecessary in subsequent process. Another aspect is, the doped area, i.e, collector, is formed by ion implantation instead of high cost epitaxy process. This invention simplified the manufacturing process, as a consequence, saved manufacturing cost.

  • Patent number: 8222114
    Abstract: This invention disclosed a novel manufacturing approach of collector and buried layer of a bipolar transistor. One aspect of the invention is that an oxide-nitride-oxide (ONO) sandwich structure is employed instead of oxide-nitride dual layer structure before trench etching. Another aspect is, through the formation of silicon oxide spacer in trench sidewall and silicon oxide remaining in trench bottom in the deposition and etch back process, the new structure hard mask can effectively protect active region from impurity implanted in ion implantation process.

  • Publication number: 20110156163
    Abstract: This invention disclosed a kind of electrode picking up structure in LOCOS isolation process. The active region is isolated by local oxide of silicon (LOCOS). A pseudo buried layer under the bottom of LOCOS is formed. The pseudo-buried layer extends into active region and connects to doping region one which needs to be picked up by an electrode. This is achieved by deep trench contacts which etch through LOCOS and get in touch with pseudo buried layer. This invention can reduce the device size, pick up electrode resistance, collector parasitic capacitance, and increase device cut off frequency.

  • Publication number: 20110156151
    Abstract: This invention disclosed a kind of electrode pick up structure in shallow trench isolation process. The active region is isolated by shallow trench. A pseudo-buried layer under the bottom of shallow trench is formed. The pseudo-buried layer extends into active region and connects to doping region one which needs to be picked up by an electrode. The pick up is realized by deep trench contacts which etch through STI and get in touch with pseudo buried layer. This invention can reduce the device size, pick up electrode resistance, collector parasitic capacitance, and increase device cut off frequency.
