A COMPARATIVE STUDY BETWEEN SILICON, METALS AND SOME BIODEGRADABLE MATERIALS IN THE GATE FABRICATION PROCESS OF THE VOLTAGE CONTROLLED SWITCH TRANSISTOR: EXPERIMENTALLY AND THEORETICALLY

Abstract

Recently, sustainable issues are the significant subject of the environmental attributes which encourage manufacturers to look for biodegradable and bio-sourced products in any application besides lower costs and improved performance.In this paper a comparative study between using the silicon material instead of metal in the formulation of the gate of the Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) has been presented. Substitution of traditional materials to manufacture the gate of the voltage controlled switch (MOSFET) by alternative polymers to meet environmental requirements and understood the need for sustainable issues are also introduced.A theoretical review was involving mathematical calculations to realize the difference in employing the silicon and other metals such as copper in fabrication process. The experimental test process in this approach was focused on the characteristics of the selective material to provide the required electrical properties with respect to specific layout dimensions of the sheet of the gate.
