    摘要: An improved NPN bipolar transistor integratable with CMOS FET processing is achieved. The transistor is formed on a substrate using a CMOS process and one additional masking and implant step. The CMOS N wells are used to form the collector contacts (reachthrough) and the P wells are used to form the base. N doped third wells are formed under the N wells, P wells, and shallow trench isolation regions to provide subcollectors. Since the P wells are not implanted through the STI, basewidths are reduced and current gain is increased. Gate electrode masking elements, formed over the base, separate the emitter and base contact regions, improving the emitter-to-base breakdown voltage. The CMOS source/drain N type implants then form emitters in the emitter regions and ohmic contacts in the collector contacts. The source/drain P type implants form the ohmic base contacts to complete the bipolar transistor.

    摘要: Disclosed is a technology by which rules on communication permission or control are enforced to network internal devices such that an environment which looks as if to have a virtual firewall existing between network internal devices can be established. A communication control apparatus for this is located on the same level in the network as other devices are located. By using this communication control apparatus, an address resolution protocol (ARP) packet in which a data link layer address is manipulated is provided to devices that are the objects of communication cut-off, such that data packets transmitted by the communication cut-off object devices are transmitted to manipulated abnormal addresses. By doing so, communication with the communication cut-off object devices is cut off. For a device which is in a communication cut-off state although the device is not an object of communication cut-off any more, the communication control apparatus transmits an ARP packet including normal address information to the device such that the communication cut-off state is canceled.

    摘要: A process for simultaneously forming a polysilicon gate structure, for a transfer gate transistor, and a polysilicon top plate, for a capacitor structure, on an underlying planar surface, has been developed. The process features the formation of a polysilicon bottom plate, for the capacitor structure, embedded in a first opening in composite insulator layer, and the formation of an active device region, for a transfer gate transistor structure, via the selective growth of an epitaxial silicon layer, in a second opening of the composite insulator layer, resulting in a planar top surface topography. The presence of this topography reduces the risk of residual polysilicon, present after patterning of the polysilicon gate structure, and of the capacitor, polysilicon top plate.
