Abstract: Lateral PNP bipolar junction transistors, methods for fabricating lateral PNP bipolar junction transistors, and design structures for a lateral PNP bipolar junction transistor. An emitter and a collector of the lateral PNP bipolar junction transistor are comprised of p-type semiconductor material that is formed by a selective epitaxial growth process. The source and drain each directly contact a top surface of a device region used to form the emitter and collector. A base contact may be formed on the top surface and overlies an n-type base defined within the device region. The emitter is laterally separated from the collector by the base contact. Another base contact may be formed in the device region that is separated from the other base contact by the base.

Abstract: A hybrid transistor (58) has a substrate (42) with a first (e.g., P type) well region (46) and a second (e.g., N type) well region (44) with an NP or PN junction (43) therebetween. A MOS portion (70-3) of the hybrid transistor (58) has an (e.g., N type) source region (48) in the first well region (46) and a gate conductor (52) overlying and insulated from the well regions (46, 44) that extends laterally at least to the junction (43). A drain or anode (D/A) portion (71-3) in the second well region (44) collects current 56 from the source region (48), and includes a bipolar transistor (78) having an (e.g., N+) emitter region (64), a (e.g., P type) base region (59) and a (e.g., N type) collector region (62) laterally separated from the junction (43). Different LDMOS-like or IGBT-like properties are obtained depending on whether the current 56 is extracted from the hybrid transistor (58) via the bipolar transistor (78) base (59) or emitter (64) or both.

Abstract: An integrated circuit arrangement and fabrication method is provided. The integrated circuit arrangement contains an NPN transistor and a PNP transistor. The PNP transistor contains an emitter connection region and a cutout. The cutout delimits the width of the emitter connection region. The electrically conductive material of the connection region laterally overlaps the cutout.

Abstract: A semiconductor structure is fabricated with two different portions. The first portion forms a first transistor, while the second portion forms a second transistor. Notably, portions of the first transistor also a make up portions of the second transistor. That is, both the first transistor and the second transistor are made of portions of the same structure.

Abstract: A high fT and fmax bipolar transistor includes an emitter, a base, and a collector. The emitter has a lower portion and an upper portion that extends beyond the lower portion. The base includes an intrinsic base and an extrinsic base. The intrinsic base is located between the lower portion of the emitter and the collector. The extrinsic base extends from the lower portion of the emitter beyond the upper portion of the emitter and includes a continuous conductor that extends from underneath the upper portion of the emitter and out from underneath the upper portion of the emitter. The continuous conductor provides a low electrical resistance path from a base contact (not shown) to the intrinsic base. The transistor may include a second conductor that does not extend underneath the upper portion of the emitter, but which further reduces the electrical resistance through the extrinsic base.

Abstract: The present invention relates to a lateral PNP transistor and the method of manufacturing the same. The medium doping N-type base area and the light doping P? collector area were first introduced in the structure before the formation of P+ doping emitter area and the collector area. The emitter-base-collector doping profile in the lateral and the base width of LPNP were similar to NPN. The designer can optimize the doping profile and area size of each area according to the request of the current gain (Hfe), collector-base breakdown voltage (BVceo), and early voltage (VA) of LPNP transistor. These advantages may cause to reduce the area and enhance performance of the LPNP transistor.

Abstract: The invention relates to a field effect transistor in which the planar channel region on the upper surface of the elevation is extended in width by means of additional vertical channel regions on the lateral surfaces of the elevation. Said additional vertical channel regions connect directly to the planar channel region (vertical extended channel regions). Said field effect transistor has the advantage that a significant increase in the effective channel width for the current flow ION can be guaranteed relative to conventional transistor structures used up until the present, without having to accept a reduction in the achievable integration density. Said field effect transistor furthermore has a low reverse current IOFF. The above advantages are achieved without the thickness of the gate insulators up to the region of the charge transfer tunnels having to be reduced or a reduced stability.
