20080213987 | Method of Fabricating a Sige Semiconductor Structure - A method of fabricating an integrated circuit includes providing a substrate and creating base-windows in a layer. The method also includes forming a monocrystalline SiGe base layer in each of the base layers, and polycrystalline SiGe elsewhere. Additionally, the method also includes forming a monocrystalline silicon layer over selectively exposed portions of the surface of the substrate. The integrated circuit beneficially includes silicon-based elements such as a lateral pnp transistor, a varactor, and a polysilicon transistor, which are formed on a common substrate with an npn SiGe bipolar transistor. | 09-04-2008 |
20090079031 | METHOD AND DEVICE WITH IMPROVED BASE ACCESS RESISTANCE FOR NPN BIPOLAR TRANSISTOR - A configuration composed of multiple short emitters still share common DTI regions and a single big piece of base poly. This allows for base current to flow in 4 directions (e.g., 2 dimensions) as opposed to only two. This significantly reduces the base resistance of the transistor that is crucial for better NPN transistor RF performance and high frequency noise performance. | 03-26-2009 |

20110147884 | Contacting and Filling Deep-Trench-Isolation with Tungsten - Electrically isolated, deep trench isolation (DTI) structures, are formed in a wafer, and a portion of the DTI structures are converted to electrically connected structures to provide a shielding function, or to provide connection to deep buried layers. In one aspect, DTI structures include a polysilicon filling over a liner layer disposed on the inner surface of a deep trench, the polysilicon is removed by isotropic etching, and the deep trench is re-filled with a conductive material. Alternatively, the polysilicon filling remains and a contact is formed to provide an electrical connection to the polysilicon. In another aspect, a deep trench is disposed in the wafer such that a lower portion thereof is located within a deep buried layer, and after the polysilicon is removed, an anisotropic etch removes a portion of the deep trench liner from the bottom of the deep trench, thereby allowing a tungsten deposition to make electrical contact with the deep buried layer. | 06-23-2011 |
