The principle of complementary symmetry was first introduced by George Sziklai in 1953 who then discussed several complementary bipolar circuits. Paul Weimer, also at RCA, invented in 1962 thin-film transistor (TFT) complementary circuits, a close relative of CMOS. He invented complementary flip-flop and inverter circuits, but did no work in a more complex complementary logic. He was the first person able to put p-channel and n-channel TFTs in a circuit on the sam… Websoc工艺课件双阱CMOS工艺晶横完片截整的面横放晶截大片面晶片 Page 2 N阱的制作衬底上生长SiO2 涂敷光刻胶 1-NN阱阱掩膜版(N-Well) 氧化层光刻胶 P型衬底剖面图 N阱掩膜版 Page 3 版图 N阱的制作衬底上生长SiO2 涂敷光刻胶曝光 N阱掩膜版显影涂敷光刻胶
