Abstract:
1. A thin film transistor (TFT), comprising: an active layer including a source region, a drain region, and a channel region, the active layer including a plurality of doped regions and at least one undoped region; a first metal member arranged on the active layer to correspond to a portion of each of the source region and the drain region, wherein the at least one undoped region includes a first portion of the active layer that corresponds to the first metal member; an upper insulating layer arranged on the first metal member, the upper insulating layer being perforated by a pair of contact holes that expose portions of the first metal member; a gate electrode arranged to correspond to the channel region of the active layer; and a second metal member to electrically connect each of the source region and the drain region to an external element.
