He is best known for inventing <a href="/facts/CMOS/NJIWYgBl">CMOS</a> (complementary <a href="/facts/MOSFET/eTDJT2Km">MOS</a>) logic in 1963. CMOS has since become the standard <a href="/facts/Semiconductor_device_fabrication/Jd23Mu1z">semiconductor device fabrication</a> process for <a href="/facts/MOSFET/eTDJT2Km">MOSFETs</a> (metal–oxide–semiconductor field-effect transistors). </p>
