  • Patent number: 8466501
    Abstract: An asymmetric silicon-on-insulator (SOI) junction field effect transistor (JFET) and a method. The JFET includes a bottom gate on an insulator layer, a channel region on the bottom gate and, on the channel region, source/drain regions and a top gate between the source/drain regions. STIs isolate the source/drain regions from the top gate and a DTI laterally surrounds the JFET to isolate it from other devices. Non-annular well(s) are positioned adjacent to the channel region and bottom gate (e.g., a well having the same conductivity type as the top and bottom gates can be connected to the top gate and can extend down to the insulator layer, forming a gate contact on only a portion of the channel region, and/or another well having the same conductivity type as the channel and source/drain regions can extend from the source region to the insulator layer, forming a source-to-channel strap).

  • Patent number: 8030167
    Abstract: Methods are disclosed for forming a varied impurity profile for a collector using scattered ions while simultaneously forming a subcollector. In one embodiment, the invention includes: providing a substrate; forming a mask layer on the substrate including a first opening having a first dimension; and substantially simultaneously forming through the first opening a first impurity region at a first depth in the substrate (subcollector) and a second impurity region at a second depth different than the first depth in the substrate. The breakdown voltage of a device can be controlled by the size of the first dimension, i.e., the distance of first opening to an active region of the device. Numerous different sized openings can be used to provide devices with different breakdown voltages using a single mask and single implant. A semiconductor device is also disclosed.

  • Patent number: 7709930
    Abstract: Disclosed is a method of forming a semiconductor structure that includes a discontinuous non-planar sub-collector having a different polarity than the underlying substrate. In addition, this structure includes an active area (collector) above the sub-collector, a base above the active area, and an emitter above the base. The distance between the discontinuous portions of the discontinuous sub-collector tunes the performance characteristics of the semiconductor structure. The performance characteristics that are tunable include breakdown voltage, unity current gain cutoff frequency, unity power gain cutoff frequency, transit frequency, current density, capacitance range, noise injection, minority carrier injection and trigger and holding voltage.

  • Patent number: 7701015
    Abstract: Disclosed is a method and structure for an integrated circuit structure that includes a plurality of complementary metal oxide semiconductor (CMOS) transistors and a plurality of vertical bipolar transistors positioned on a single substrate. The vertical bipolar transistors are taller devices than the CMOS transistors. In this structure, a passivating layer is positioned above the substrate, and between the vertical bipolar transistors and the CMOS transistors. A wiring layer is above the passivating layer. The vertical bipolar transistors are in direct contact with the wiring layer and the CMOS transistors are connected to the wiring layer by contacts extending through the passivating layer.

  • Publication number: 20090057815
    Abstract: Methods of manufacturing a semiconductor structure are disclosed including a deep trench isolation in which a channel stop is formed in the form of an embedded impurity region in the substrate prior to the deep trench etch and formation of transistor devices (FEOL processing) on the substrate. In this fashion, the FEOL processing thermal cycles can activate the impurity region. The deep trench isolations are then formed after FEOL processing. The method achieves the reduced cost of forming deep trench isolations after FEOL processing, and allows the practice of sharing of a collector level between devices to continue. The invention also includes the semiconductor structure so formed.

  • Patent number: 7479439
    Abstract: A semiconductor-insulator-silicide (SIS) capacitor is formed by depositing a thin silicon containing layer on a salicide mask dielectric layer, followed by lithographic patterning of the stack and metallization of the thin silicon containing layer and other exposed semiconductor portions of a semiconductor substrate. The thin silicon containing layer is fully reacted during metallization and consequently converted to a silicide alloy layer, which is a first electrode of a capacitor. The salicide mask dielectric layer is the capacitor dielectric. The second electrode of the capacitor may be a doped polycrystalline silicon containing layer, a doped single crystalline semiconductor region, or another doped polycrystalline silicon containing layer disposed on the doped polycrystalline silicon containing layer. The SIS insulator may further comprise other dielectric layers and conductive layers to increase capacitance per area.

  • Patent number: 7253096
    Abstract: A bipolar transistor with raised extrinsic base and selectable self-alignment between the extrinsic base and the emitter is disclosed. The fabrication method may include the formation of a predefined thickness of a first extrinsic base layer of polysilicon or silicon on an intrinsic base. A dielectric landing pad is then formed by lithography on the first extrinsic base layer. Next, a second extrinsic base layer of polysilicon or silicon is formed on top of the dielectric landing pad to finalize the raised extrinsic base total thickness. An emitter opening is formed using lithography and RIE, where the second extrinsic base layer is etched stopping on the dielectric landing pad. The degree of self-alignment between the emitter and the raised extrinsic base is achieved by selecting the first extrinsic base layer thickness, the dielectric landing pad width, and the spacer width.
