  • Thin film transistor, and manufacturing method thereof
    Publication number: 20010022361
    Abstract: The present invention relates to minimizing a leakage current in a floating island portion formed in a thin film transistor. More specifically, the present invention is directed to a thin film transistor including: a source electrode 14 and a drain electrode 15 disposed above an insulating substrate 11 at a predetermined interval; an s-Si film 16 disposed in relation to the source electrode 14 and drain electrode 15; a gate insulating film 17 overlapping the a-Si film 16; and a gate electrode 18 overlapping the gate insulating film 17, in which the a-Si film 16 is disposed between the source electrode 14 and the drain electrode 15 and has a floating island portion 20 above which or beneath which the gate electrode 18 is not formed, and boron ions are implanted into this portion to form a boron-ion-implanted region 19.
