  • 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...

  • Vacuum-deposited aluminum-oxide MOS transistors

    Creator:
    Hwang, Yun-sheng
    Abstract:
    The properties of evaporated aluminum-oxide films were investigated. The characteristics of MOS devices made with single-layer aluminum-oxide films and double-layer films which were made by evaporating aluminum oxide over thermally-grown silicon dioxide as gate insulation have been investigated. Vacuum-evaporated aluminum oxide has features which are suitable for fabricating MOS devices....

  • Acoustic surface wave delay device

    Creator:
    Bhaskar, Eldurkar Vamanrao
    Abstract:
    This thesis is an experimental study of an acoustic surface wave delay line using a Lithium Niobate crystal. A brief theory of operation of the interdigital transducer with its advantages over the other methods of exciting and detecting acoustic surface waves is discussed. The experimental procedure used for evaluation of...

  • Influence of surface fields on shallow planar-junction breakdown voltages

    Creator:
    Kim, Sŭng-yŏng
    Abstract:
    The influence of surface fields on the breakdown voltage is studied experimentally for p⁺-n silicon diodes with a junction depth of 0.5μ in order to improve the curvature- limited breakdown of the diffused, shallow-collector junction of a microwave transistor. Devices with a gap in the gate metal electrode are also...

  • The high frequency performance of a Schottky diode detector

    Creator:
    Crane, Albert Sears
    Abstract:
    This paper analyzes the theory and performance of a Schottky barrier diode detector used over a frequency range extending from a few kilohertz into the gigahertz region. The process of large signal rectification is analyzed with the simplified detector circuit. Phenomena which can affect the rectification process at high frequencies,...

  • An integrated MOS voltage-controlled low frequency oscillator

    Creator:
    Araghi, Mehdi Najm
    Abstract:
    In this work the use of linear MOS integrated circuits in the design of a phase-shift oscillator is presented. By multiplying the capacitors of the RC feedback network through the use of the Miller effect, large effective capacitance values are obtained which enable the low frequency operation of the oscillator....

  • The MOS tetrode transistor

    Creator:
    Limvorapun, Thawee
    Abstract:
    The MOS tetrode transistor is studied in this project. This device is ideally suited for high frequency and switching application. In effect it is the solid state analogy of a multigrid vacuum tube performing a very useful multigrid function. A new structure is developed for p-channel 10 ohm-cm. silicon substrate...

  • Hall-effect devices for instructional use

    Creator:
    Dills, Gerald Frederick
    Abstract:
    Problems with Hall devices for instructional use in undergraduate laboratories stimulated this investigation for development of rugged, easily constructed, inexpensive, electrically reproducible Hall devices with high output voltage. Silicon was chosen as the Hall-plate material on the basis of cost and availability. Advantages and disadvantages of various plate shapes, sizes,...

  • 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....
