Patent number: 7728359Abstract: In a nitride semiconductor based bipolar transistor, a contact layer formed so as to contact an emitter layer is composed of n-type InAlGaN quaternary mixed crystals, the emitter layer and the contact layer are selectively removed so that the barrier height with the emitter formed thereon is small, and the ohmic electrode contact resistance can be lowered on the InAlGaN quaternary mixed crystals, for example, so that a WSi emitter electrode becomes an eave. A base electrode is formed by a self-aligned process using the emitter electrode as a mask. By such a configuration, the distance between the emitter and the edge of the base electrode is sufficiently shortened, and the base resistance can be lowered. As a result, a bipolar transistor having favorable high-frequency characteristics can be realized.Type: GrantFiled: June 20, 2007Date of Patent: June 1, 2010Assignee: Panasonic CorporationInventors: Tatsuo Morita, Tetsuzo Ueda

Patent number: 7728364Abstract: The present invention provides structures and methods for a transistor formed on a V-shaped groove. The V-shaped groove contains two crystallographic facets joined by a ridge. The facets have different crystallographic orientations than what a semiconductor substrate normally provides such as the substrate orientation or orientations orthogonal to the substrate orientation. Unlike the prior art, the V-shaped groove is formed self-aligned to the shallow trench isolation, eliminating the need to precisely align the V-shaped grooves with lithographic means. The electrical properties of the new facets, specifically, the enhanced carrier mobility, are utilized to enhance the performance of transistors. In a transistor with a channel on the facets that are joined to form a V-shaped profile, the current flows in the direction of the ridge joining the facets avoiding any inflection in the direction of the current.Type: GrantFiled: January 19, 2007Date of Patent: June 1, 2010Assignee: International Business Machines CorporationInventors: Huilong Zhu, Thomas W.

Patent number: 7705361Abstract: A heterojunction bipolar transistor (HBT) has a (In)(Al)GaAsSb/InGaAs base-collector structure. A discontinuous base-collector conduction band forms a built-in electric field to infuse electrons into a collector structure effectively, while a discontinuous base-collector valence band prevents holes from spreading into the collector structure at the same time. Thus, a current density is increased. In addition, the small offset voltage of the base-emitter and base-collector junctions reduce a power consumption.Type: GrantFiled: June 7, 2007Date of Patent: April 27, 2010Assignee: National Central UniversityInventors: Sheng-Yu Wang, Jen-Inn Chyi, Shu-Han Cheng
