Federico Faggin developed a theory of physics which posits that consciousness, not matter, is the ground of being. He developed the silicon chip, the microprocessor at the heart of all electronic devices today such as your computer. He led the 4004 (MCS-4) project and the design group during the first five years of Intel‘s microprocessor effort. He created the self-aligned metal–oxide–semiconductor(MOS) silicon-gate technology (SGT), which made possible MOS semiconductor memory chips, CCD image sensors, and the microprocessor.
