Abstract

Provided is an amorphous silicon thin-film transistor including an amorphous silicon semiconductor layer, a source electrode, and a drain electrode that are successively disposed on a base substrate. Ions doped by an ion implantation process are present in a region, proximal to the source electrode and the drain electrode, of the amorphous silicon semiconductor layer. A concentration of the ions in a surface region, proximal to the source electrode and the drain electrode, of the amorphous silicon semiconductor layer is greater than or equal to 5*10{circumflex over ( )}20 atoms/cc.
