  • A MOS-transistor with submicron, and graded channel

    Creator:
    Chou, Pen Chao
    Abstract:
    The theoretical aspects and fabrication techniques of a new surface field-effect transistor were investigated. The new MOS-transistor uses a three-layer structure similar to those found in bipolar transistors. The new MOS structure introduces an impurity gradient in the channel region of the transistor and also makes it possible to reduce...

  • A complementary MOS random-access-memory cell wth double-diffused MOS transistors

    Creator:
    Tao, David Ming-Shih
    Abstract:
    The use of double-diffused n-type MOS transistor (DN-MOS) in a complementary MOS random-access-memory (CMOS RAM) cell is the main objective of this investigation. DN-MOS transistors and conventional p-channel MOS transistors on the same chip have been successfully fabricated. Process sequence effects on device threshold voltage and channel length are discussed....

  • Vacuum evaporated dielectrics in MOS structures

    Creator:
    Delzer, Dennis Richard
    Abstract:
    Vacuum evaporated dielectrics for use in MOS structures were studied in this research project. Dielectric films were deposited on substrates by electron bombardment evaporation of sapphire and quartz source materials. These deposited films were studied using infrared spectroscopy, index of refraction, density, and dielectric constant measurements. Etching tests were also...

  • High-efficiency radio-frequency power amplifiers

    Creator:
    Ewing, Gerald Dean
    Abstract:
    This dissertation describes a new radio-frequency power-amplifier circuit and mode of operation that exceeds the efficiency of the conventional class C amplifier in the low and medium h-f range. It will be found useful in applications where linearity between the input and output are not required, as in all applications...

  • Liquid-gated carbon nanotube transistor noise sources and sensitivity limits

    Creator:
    Sharf, Tal
    Abstract:
    Low-dimensional electronic materials offer a platform to observe biological processes with unprecedented spatial and temporal resolution. Carbon nanotubes (CNTs) are the closest physical analog to an ideal 1D system and can be scaled and integrated into multiplexed electronic circuitry. The molecular structure of a CNT is also biocompatible, making them...
