A method and an apparatus are provided for manufacturing an active matrix device including a top gate type TFT. A manufacturing process of the top gate type TFT includes the steps of forming an oxide film on the inner wall of a CVD processing chamber and arranging a substrate having source and drain electrodes formed thereon in the processing chamber. Additional steps include doping the source and drain electrodes with P, and forming an a-Si layer and a gate insulating film in the processing chamber. Furthermore, an apparatus is provided for manufacturing an active matrix device including a top gate type TFT having the inner surface of the processing chamber coated with the oxide film.

The present invention improves a productivity in growing an a-Si film in a thin film transistor and to obtain an excellent thin film transistor characteristic. More specifically, disclosed is a thin film transistor in which an amorphous silicon film 2, a gate insulating film 3 and a gate electrode are sequentially stacked on an insulating substrate 1. The amorphous silicon film 2 includes a low defect-density amorphous silicon layer 5 formed at a low deposition rate and a high deposition rate amorphous silicon layer 6 formed at a deposition rate higher than that of the low defect-density amorphous silicon layer 5. The low defect-density amorphous silicon layer 5 in the amorphous silicon film 2 is grown closer to the insulating substrate 1, and the high deposition rate amorphous silicon layer 6 is grown closer to the gate insulating film 3.

The present invention reduces the number of necessary steps in a thin-film-transistor manufacturing process and prevents an abnormal potential from being generated due to a leak current from another data line. More particularly, the present invention is directed to a thin film transistor comprising a gate electrode 30 disposed on a predetermined substrate and formed in a predetermined pattern, a semiconductor layer formed correspondingly to patterning of the gate electrode 30, a pixel electrode 25 interposed by the semiconductor layer, and a signal electrode 26 interposed by the semiconductor layer and disposed at a predetermined interval from the pixel electrode 25, in which the signal electrode 26 is disposed at such a position where the signal electrode prevents crosstalk running from adjacent signal lines 32b and 32c to the pixel electrode 25 via the semiconductor layer.

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.

A thin film transistor and method of making the same is disclosed in which a contact hole is formed with a flattened interface between openings in an inorganic material passivation layer and an organic material interlayer insulating film thereabove. The method includes etching an opening in the interlayer insulating film, using that opening as a mask for subsequently etching a self-aligned opening in the passivation layer, and again etching the interlayer insulating film in a develop back process to obtain a contact hole having a flattened inner sidewall.
