Active matrix type display device and fabrication method of the same
摘要:
There is provided an active matrix type display in which thin film transistors having required characteristics are provided selectively in a pixel matrix portion and a peripheral driving circuit portion. In a structure having the pixel matrix portion and the peripheral driving circuit portion on the same substrate, N-channel type thin film transistors having source and drain regions formed through a non-self-alignment process and low concentrate impurity regions formed through a self-alignment process are formed in the pixel matrix portion and in an N-channel driver portion of the peripheral driving circuit portion. A P-channel type thin film transistor in which no low concentrate impurity region is formed and source and drain regions are formed only through the self-alignment process is formed in a P-channel driver portion of the peripheral driving circuit portion.
