    摘要: Disclosed is a transistor with a raised collector pedestal in reduced dimension for reduced base-collector junction capacitance. The raised collector pedestal is on the top surface of a substrate, extends vertically through dielectric layer(s), is un-doped or low-doped, is aligned above a sub-collector region contained within the substrate and is narrower than that sub-collector region. An intrinsic base layer is above the raised collector pedestal and the dielectric layer(s). An extrinsic base layer is above the intrinsic base layer. Thus, the space between the extrinsic base layer and the sub-collector region is increased. This increased space is filled by dielectric material and the electrical connection between the intrinsic base layer and the sub-collector region is provided by the relatively narrow, un-doped or low-doped, raised collector pedestal. Consequently, base-collector junction capacitance is reduced and, consequently, the maximum oscillation frequency is increased.

    摘要: A variable capacitance device including a plurality of FETs, the sources and drains of each FET being coupled to a first terminal, the gates of each FET being coupled to a second terminal, the capacitance of said device between said first and second terminals varying as a function of the voltage across said terminals, the device further including a biasing providing a respective backgate bias voltage to each the FETs setting a respective gate threshold voltage thereof. The aggregate V-C characteristic can be tuned as desired, either at design time or dynamically. The greater the number of FETs forming the varactor, the greater the number of possible Vt values that can be individually set, so that arbitrary V-C characteristics can be more closely approximated.

The method may comprise forming a first gate oriented in a first direction over an active region of a semiconductor substrate, forming a second gate extending perpendicular to the first gate over a second active region, using a dual-directional implant process to form a reduced-HALO doped area on a drain side of the first gate and also for a HALO doped area for the second gate, while the source side of the first gate is covered by a resist. Additionally, the method may comprise forming a HALO doped area on the source side of the first gate using a quad-directional implant process using the mask also used for HALO implants of other digital-logic devices on the substrate, while the drain side of the gate is blocked by a resist.
