  • Publication number: 20090241075
    Abstract: Embodiments of an IC design system for test row/structure layout design are described in this application. The design system may include a test chip complier database, a test chip complier engine (TCCE), and a user interface module. The TCCE may be configured to communicate with at least the test chip compiler database and the user interface module, and configured to allow a user to automatically generate a test chip layout by providing an integrated circuit design system. With the system, a user can automatically generate a design by specifying the test row or test structure layout requirements for the design using sets of predefined templates, changing design template parameters using a table driven input format, scheduling generation of the design on a preferred layout design tool, visually inspecting the generated design for errors, and/or applying version controls to the generated design. Other embodiments are described.

  • Patent number: 7517768
    Abstract: A bipolar transistor with a SiGe:C film and a seed layer forming beneath the SiGe:C film and methods of making same. The method includes placing a substrate in a reactor chamber and introducing a silicon source gas into the reactor chamber to form a silicon seed layer. The reactor chamber is maintained at a pressure below 45 Torr and a temperature between about 700° C. and 850° C. After the seed layer is formed, the silicon source gas is stopped. The reactor chamber is then simultaneously adjusted to a pressure between about 70 Torr and 90 Torr and a temperature between about 600° C. and 650° C. The silicon source gas, a germanium source gas, and a carbon source gas are introduced to form the SiGe:C film on the seed layer.

  • Patent number: 7202514
    Abstract: The invention relates to a process of forming a bipolar junction transistor (BJT) that includes forming a topology over a substrate. Thereafter, a spacer is formed at the topology. A base layer is formed from epitaxial silicon above the spacer and at the topology. A leakage block structure is formed in the substrate by out-diffusion from the spacer. Thereafter a BJT is completed with the base layer and the spacer.

  • Publication number: 20060113634
    Abstract: A bipolar transistor and its fabrication are described. The extrinsic base region is formed by growing a second, more heavily doped, epitaxial layer over a first epitaxial layer. The second layer extends under, and is insulated from, an overlying polysilicon emitter pedestal.
