Abstract:

The report contains Microelectronics and all phases of thin film microelectronic circuit and system fabrication. A block diagram of the digital full adder chosen as a vehicle for this initial effort is shown. Digital circuits lend themselves to present day microelectronic fabrication techniques because of their low power consumption, wide allowable component tolerances and high circuit redundancy. There are no capacitors required in the circuit design chosen. The fabrication of capacitors is not difficult, however, the choice was made to simplify the preliminary investigation. The full adder system to be fabricated consisted of three dual inverters, seven NOR circuits, two OR circuits and two light circuits used to display the output of the digital addition. Author
