The Bootstrap Load
Home Back The Intel 4004 Microprocessor and the Silicon Gate Technology A testimonial from Federico Faggin, designer of the 4004 and developer of its enabling technology Quick Links: Silicon Gate Technology The Buried Contact The Gilbert Hyatt Patent The Bootstrap Load At Fairchild, Faggin also built bootstrap load devices in early 1970, using the silicon gate technology . Bootstrap load is a circuit technique that allows building logic gates with the output voltage equal to the full supply voltage compared with a normal resistive load where the output voltage reaches about 60% of the supply voltage.
At Fairchild, Faggin also built bootstrap load devices in early 1970, using the silicon gate technology. The bootstrap load devices required the fabrication of good-quality capacitors on a chip that were thought impossible to manufacture with SGT without using an extra masking layer. "(Faggin, in a 2007 oral panel interview with David House CHM), and he showed how to make bootstrap load devices without an extra masking layer.
