Abstract: A process of forming a CMOS integrated circuit by forming a first stressor layer over two MOS transistors of opposite polarity, removing a portion of the first stressor layer from the first transistor, and forming a second stressor layer over the two transistors. A source/drain anneal is performed, crystallizing amorphous regions of silicon in the gates of the two transistors, and subsequently removing the stressor layers. A process of forming a CMOS integrated circuit by forming two transistors of opposite polarity, forming a two stressor layers over the transistors, annealing the integrated circuit, removing the stressor layers, and siliciding the transistors. A process of forming a CMOS integrated circuit with an NMOS transistor and a PMOS transistor using a stress memorization technique, by removing the stressor layers with wet etch processes.
