THIN-FILM TRANSISTOR AND LIQUID CRYSTAL DISPLAY AND CMOS CIRCUIT USING THIN-FILM TRANSISTOR THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a TFT(a thin-film transistor), reliability of which can be improved by reducing a partial temperature rise by self-heat generation without increasing the number of manufacturing processes, and a liquid crystal display with an active matrix substrate using the TFT for a driver circuit, etc. ;SOLUTION: Offset regions 7 are formed to sections (the sections oppositely faced to the end sections of a gate electrode 4) between the source-drain regions 8 and a channel region 5 in the TFT. Since a central section in the channel width direction is projected towards the sections of the source-drain regions 8 in the boundary sections 70 among the offset regions 7 and the source-drain regions 8 in high concentration, the offset regions 7 have structure, in which the offset length Loffc of the central section in the channel width direction is made longer than the offe of the edge sections.;COPYRIGHT: (C)1998,JPO
