  • Publication number: 20120270343
    Abstract: A polishing method and a method for forming a gate are provided. The method includes forming a dummy gate on a semiconductor substrate including a sacrificial oxide layer and a polysilicon layer which covers the sacrificial oxide layer, forming spacers around the dummy gate, and successively forming a silicon nitride layer and a dielectric layer covering the silicon nitride layer. The method further includes polishing the dielectric layer until the silicon nitride layer is exposed, polishing the silicon nitride layer on a fixed abrasive pad until the polysilicon layer is exposed by using a polishing slurry with a PH value ranging from 10.5 to 11 and comprising an anionic surfactant or a zwitterionic surfactant. Additionally, the method includes forming an opening after removing the dummy gate, and forming a gate in the opening. The method eliminates potential erosion and dishing caused in the polishing of the silicon nitride layer.

  • Patent number: 8293544
    Abstract: A method (and semiconductor device) of fabricating a semiconductor device utilizes a thermal proximity correction (TPC) technique to reduce the impact of thermal variations during anneal. Prior to actual fabrication, a location of interest (e.g., a transistor) within an integrated circuit design is determined and an effective thermal area around the location is defined. Thermal properties of structures intended to be fabricated within this area are used to calculate an estimated temperature that would be achieved at the location of interest from a given anneal process. If the estimated temperature is below or above a predetermined target temperature (or range), TPC is performed. Various TPC techniques may be performed, such as the addition of dummy cells and/or changing dimensions of the structure to be fabricated at the location of interest (resulting in an modified thermally corrected design, to suppress local variations in device performance caused by thermal variations during anneal.

  • Publication number: 20120248506
    Abstract: The present invention relates to integrating an inertial mechanical device on top of a CMOS substrate monolithically using IC-foundry compatible processes. The CMOS substrate is completed first using standard IC processes. A thick silicon layer is added on top of the CMOS. A subsequent patterning step defines a mechanical structure for inertial sensing. Finally, the mechanical device is encapsulated by a thick insulating layer at the wafer level. Comparing to the incumbent bulk or surface micromachined MEMS inertial sensors, the vertically monolithically integrated inertial sensors have smaller chip size, lower parasitics, higher sensitivity, lower power, and lower cost.
