摘要： A photoconductive member is provided with increased sensitivity to radiation incident thereupon and with increased photo-yield in response thereto by means of a multi-layered, sandwich-type construction based upon the provision of successive layers of sensitizing material over corresponding successive layers of conducting material. The photoconductive member comprises at least two composite layers formed one above the other on an insulating substrate, each composite layer comprising a first layer of material capable of conducting charge and a second layer of material comprising polar molecules disposed upon the charge-conducting material layer in such a manner that successive layers of polar molecules are adsorbed and retained in an oriented fashion on successive layers of the charge-conducting material. In combination, the alternating layers of charge-conducting material and polar molecules increase photo-yield in response to a given quantum of incident radiation and also increase the range of wavelength of incident radiation to which the photoconductive member is responsive. The sandwich-type construction permits photoconductor sensitivity to be increased as a function of the number of layers of conducting material and polar molecules used to form the photoconductive surface. The multi-layered construction also exhibits reduced sensitivity to the degrading effects of impurities, is adapted to convenient fabrication, and exhibits extended lifetime.

摘要： In a method of manufacturing a polysilicon thin film and a method of manufacturing a TFT having the thin film, a laser beam is irradiated on a portion of an amorphous silicon thin film to liquefy the portion of the amorphous silicon thin film. The amorphous silicon thin film is on a first end portion of a substrate. The liquefied silicon is crystallized to form silicon grains. The laser beam is shifted from the first end portion towards a second end portion of the substrate opposite the first end portion by an interval in a first direction. The laser beam is then irradiated onto a portion of the amorphous silicon thin film adjacent to the silicon grains to form a first polysilicon thin film. Therefore, electrical characteristics of the amorphous silicon thin film may be improved.

摘要： The Mo or MoW composition layer has the low resistivity less than 15 &mgr;&OHgr;cm and is etched to have a smooth taper angle using an Al alloy etchant or a Cr etchant, and the Mo or MoW layer is used for a wiring of a display or a semiconductor device along with an Al layer and a Cr layer. Since the Mo or MoW layer can be deposited so as to give low stress to the substrate by adjusting the deposition pressure, a single MoW layer can used as a wiring by itself. When contact holes are formed in the passivation layer or the gate insulating layer, a lateral etch is reduced by using a polymer layer, an etch gas system CF4+O2 can prevent the etch of the Mo or MoW alloy layer, and an etch gas SF6+HCl(+He) or SF6+Cl2(+He) can form the edge profile of contact holes to be smoothed. Also, when an amorphous silicon layer formed under the Mo or MoW layer is etched by using the Mo or MoW layer as a mask, to use an etch gas system such as hydrogen halide and at least one selected from CF4, CHF3, CHClF2, CH3F and C2F6 yield the good characteristics of TFT, and H2 plasma treatment can cause the characteristics of the TFT to be improved.
