  • Patent number: 7651919
    Abstract: A method for fabricating a heterojunction bipolar transistor (HBT) is provided. The method includes providing a substrate including a collector region; forming a compound base region over the collector region; and forming an emitter region over the compound base region including forming a first emitter layer within the emitter region and doping the first emitter layer with a pre-determined percentage of at least one element associated with the compound base region. In one implementation, an emitter region is formed including multiple emitter layers to enhance a surface recombination surface area within the emitter region.

  • Patent number: 7408812
    Abstract: The present invention is an electronic memory cell and a method for the cell's fabrication comprising a first transistor configured to be coupled to a bit line. The first transistor has an essentially zero voltage drop when activated and is configured to control an operation of the memory cell. A second transistor is configured to operate as a memory transistor and is coupled to the first transistor. The second transistor is further configured to be programmable with a voltage about equal to a voltage on the bit line.

  • Patent number: 7208795
    Abstract: An EEPROM memory transistor having a floating gate. The floating gate is formed using a BiCMOS process and has a first sinker dopant region proximate to a tunnel diode window, and a second sinker dopant region proximate to a coupling capacitor region. An optional third sinker region may be formed proximate to a source junction of the EEPROM memory transistor. Also, a shallow trench isolation (STI) region may be formed between the first and second sinker dopant regions.

  • Publication number: 20060292809
    Abstract: A method, and a resulting device, for fabricating a heterojunction bipolar transistor (HBT). HBT devices have a high transconductance typical of bipolar devices and are additionally capable of high-power operation. To achieve the aforementioned characteristics, HBT devices are generally of the npn type, preferably with a thin, heavily doped base. The thin, heavily doped base maintains a low base-spreading resistance, leading to a high maximum oscillation frequency. In order to maintain a high doping concentration while minimizing outdiffusion of the dopant material, carbon is remotely doped into the base region. Details of the carbon dopant techniques and procedures are described with respect to fabrication of an exemplary HBT device.
