DEVELOPMENT OF A BURIED-GATE POWER FIELD-EFFECT TRANSISTOR.
Abstract
Work began on development of a power FET using the buried-gate concept. During this quarter the work's main emphasis was on mask design and the development of a selective epitaxial process. Epitaxial lines, 12.7 micrometers wide, were selectively deposited with a minimum of extraneous epitaxial growth on the neighboring SiO2 mask. On a 5-ohms centimeters substrate the deposited films had average breakdown voltages of 100 volts, which reduced to 10-20 volts after epitaxial-source deposition. Devices fabricated using this process had triode characteristics because of the resulting channel shape. (Author)
