Semiconductor Pin Diode For High Frequency Applications

Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H01L 31075
US Classification:
257458, 257436, 257461
Abstract:
A microwave PIN diode having an increased intrinsic region volume for storing a charge. A semiconductor substrate has an N+ subcollector/cathode layer which encloses a region of the substrate. An N-skin formed over the interior of enclosed region. An Si layer is formed over the subcollector/cathode and N-skin to a thickness which defines the thickness for the intrinsic region of the diode. Implants are formed in the Si layer to permit contact with the subcollector/cathode layer. An anode is formed on the top of the Si layer. The total volume of the intrinsic region is increased by the N-skin which is positioned below the surface of the subcollector/cathode. The PIN diode may be formed as a lateral PIN diode thereby increasing the intrinsic region volume even further.
Dual Sidewall Spacer For A Self-Aligned Extrinsic Base In Sige Heterojunction Bipolar Transistors
Gregory G. Freeman - Hopewell Junction NY David R. Greenberg - White Plains NY Shwu-Jen Jeng - Wappingers Falls NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H01L 2976
US Classification:
257197, 257198
Abstract:
A method for forming a heterojunction bipolar transistor includes forming two sets of spacers on the sides of an emitter pedestal. After the first set of spacers is formed, first extrinsic base regions are implanted on either side of an intrinsic base. The second set of spacers is formed on the first set of spacers. Second extrinsic base regions are then implanted on respective sides of the intrinsic base. By using two sets of spacers, the first and second extrinsic base regions have different widths. This advantageously brings the combined extrinsic base structure closer to the emitter of the transistor but not closer to the collector. As a result, the base parasitic resistance is reduced along with collector-to-extrinsic base parasitic capacitance. The performance of the transistor is further enhanced as a result of the extrinsic base regions being self-aligned to the emitter and collector.

Abstract:
A method of fabricating a SiGe heterojunction bipolar transistor (HBT) is provided which results in a SiGe HBT that has a controllable current gain and improved breakdown voltage. The SiGe HBT having these characteristics is fabricated by forming an in-situ P-doped emitter layer atop a patterned SiGe base structure. The in-situ P-doped emitter layer is a bilayer of in-situ P-doped a:Si and in-situ P-doped polysilicon. The SiGe HBT structure including the above mentioned bilayer emitter is also described herein.

International Classification:
H01H 300
US Classification:
307139, 200181, 307134
Abstract:
A micro-electro mechanical switch having a restoring force sufficiently large to overcome stiction is described. The switch is provided with a deflectable conductive beam and multiple electrodes coated with an elastically deformable conductive layer. A restoring force which is initially generated by a single spring constant k upon the application of a control voltage between the deflectable beam and a control electrode coplanar to the contact electrodes is supplemented by adding to k additional spring constants k ,. . . , kn provided by the deformable layers, once the switch nears closure and the layers compress. In another embodiment, deformable, spring-like elements are used in lieu of the deformable layers. In an additional embodiment, the compressible layers or deformable spring-like elements are affixed to the deflecting beam facing the switch electrodes.
