  • Patent number: 8860142
    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.

  • Patent number: 8823136
    Abstract: A set of metal line structures including a signal transmission metal line and a capacitively-grounded inductively-signal-coupled metal line is embedded in a dielectric material layer. A capacitor is serially connected between the capacitively-grounded inductively-signal-coupled metal line and a local electrical ground, which may be on the input side or on the output side. The set of metal line structures and the capacitor collective provide a frequency dependent inductor. The Q factor of the frequency dependent inductor has multiple peaks that enable the operation of the frequency dependent inductor at multiple frequencies. Multiple capacitively-grounded inductively-signal-coupled metal lines may be provided in the frequency-dependent inductor, each of which is connected to the local electrical ground through a capacitor. By selecting different capacitance values for the capacitors, multiple values of the Q-factor may be obtained in the frequency dependent inductor at different signal frequencies.

    Abstract: An ETSOI transistor and a combination of capacitors, junction diodes, bank end contacts and resistors are respectively formed in a transistor and capacitor region thereof by etching through an ETSOI and BOX layers in a replacement gate HK/MG flow. The capacitor and other devices formation are compatible with an ETSOI replacement gate CMOS flow. A low resistance capacitor electrode makes it possible to obtain a high quality capacitor, and devices. The lack of topography during dummy gate patterning are achieved by lithography in combination accompanied with appropriate etch.
