    摘要： Disclosed are embodiments of an asymmetric field effect transistor structure and a method of forming the structure in which both series resistance in the source region (Rs) and gate to drain capacitance (Cgd) are reduced in order to provide optimal performance (i.e., to provide improved drive current with minimal circuit delay). Specifically, different heights of the source and drain regions and/or different distances between the source and drain regions and the gate are tailored to minimize series resistance in the source region (i.e., in order to ensure that series resistance is less than a predetermined resistance value) and in order to simultaneously to minimize gate to drain capacitance (i.e., in order to simultaneously ensure that gate to drain capacitance is less than a predetermined capacitance value).

    摘要： A field effect transistor (FET) has underlap regions adjacent to the channel doping region. The underlap regions have very low dopant concentrations of less than 1×1017/cc or 5×1016/cc and so tend to have a high resistance. The underlap regions reduce overlap capacitance and thereby increase switching speed. High resistance of the underlap regions is not problematic at subthreshold voltages because the channel doping region also has a high resistance at subthreshold voltages. Consequently, the present FET has low capacitance and high speed and is particularly well suited for operation in the subthreshold regime.

    摘要： Pixel sensor cells, methods of fabricating pixel sensor cells, and design structures for a pixel sensor cell. The pixel sensor cell has a gate structure that includes a gate dielectric and a gate electrode on the gate dielectric. The gate electrode includes a layer with first and second sections that have a juxtaposed relationship on the gate dielectric. The second section of the gate electrode is comprised of a conductor, such as doped polysilicon or a metal. The first section of the gate electrode is comprised of a metal having a higher work function than the conductor comprising the second section so that the gate structure has an asymmetric threshold voltage.
