  • A three-dimensional (3-D) CMOS integrated circuit with a structure, in which one type of transistor is fabricated directly above a transistor of the opposite type with separate gates and an insulator in between, has successfully been fabricated by using laser beam recrystallization. Seven-stage ring oscillators fabricated in the 3-D structure have a propagation delay of 8.2 ns. In the present experiment, a double-layer of silicon-nitride and phospho-silicate-glass (PSG) film has been used as an… CONTINUE READING
