摘要:
A thin film transistor (TFT) and a method of fabricating the same are disclosed. The TFT includes a substrate, a gate electrode disposed over the substrate, a gate insulating layer disposed over the gate electrode, a semiconductor layer disposed over the gate insulating layer and including a polycrystalline silicon (poly-Si) layer, an ohmic contact layer disposed over a predetermined region of the semiconductor layer, an insulating interlayer disposed over substantially an entire surface of the substrate including the ohmic contact layer, and source and drain electrodes electrically connected to the ohmic contact layer through contact holes formed in the interlayer insulating layer. A barrier layer is interposed between the semiconductor layer and the ohmic contact layer. Thus, when an off-current of a bottom-gate-type TFT is controlled, degradation of characteristics due to a leakage current may be prevented using a simple process.

An ion implanting system includes an ion generating system that generates ion beams and an ion implanting chamber in which a work-piece that is irradiated with the ion beams generated from the ion generating system is provided and into which the ion beams generated from the ion generating unit are directed. The ion generating system includes a first ion generating unit that irradiates ions to an upper portion of the work-piece and a second ion generating unit irradiating ions to a lower portion of the work-piece. The ion implanting system a can implant ions into a large work-piece through one ion implantation process with ion generating units arranged alternately with respect to each other in the transfer direction of the work-piece.
