Bipolar transistor semiconductor device with polysilicon emitter region
A recently granted patent (Publication Number: US11996474B2) discloses a novel bipolar transistor semiconductor device. The device comprises a substrate layer, a collector epitaxial layer, a base region, and an emitter region. The emitter region is made of polysilicon material and is supported by the base region. Additionally, a layer of Titanium (Ti) and/or Aluminium (Al) is present, supported by the collector epitaxial layer, base region, and emitter region, with the layer further comprising AlSi and/or AlSiCu. The device's construction and materials used offer unique properties and performance enhancements.
Furthermore, the patent includes a method for fabricating the bipolar transistor semiconductor device. The method involves forming the collector epitaxial layer directly on the substrate layer, creating the base region within the collector epitaxial layer, and developing the emitter region with a polysilicon material on top of the base region. A layer of Titanium (Ti) and/or Aluminium (Al) is then added, supported by the collector epitaxial layer, base region, and emitter region, with additional components like AlSi and/or AlSiCu. The fabrication process outlined in the patent ensures precise construction and functionality of the semiconductor device, showcasing advancements in manufacturing techniques for such components.
