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.
摘要翻译： Mo或MoW组合物层具有小于15μOMEGAcm的低电阻率，并且使用Al合金蚀刻剂或Cr蚀刻剂蚀刻以具有平滑的锥角，并且Mo或MoW层用于显示器或半导体的布线装置以及Al层和Cr层。由于可以通过调整沉积压力来沉积Mo或MoW层以对基底施加低应力，所以可以单个MoW层自身用作布线。当在钝化层或栅极绝缘层中形成接触孔时，通过使用聚合物层减少横向蚀刻，蚀刻气体系统CF4 + O2可以防止Mo或MoW合金层的蚀刻，并且蚀刻气体SF6 + HCl（+ He）或SF6 + Cl2（+ He）可以形成要平滑的接触孔的边缘轮廓。此外，当通过使用Mo或MoW层作为掩模蚀刻形成在Mo或MoW层下面的非晶硅层时，使用蚀刻气体系统如卤化氢和选自CF 4，CHF 3，CHClF 2，CH 3 F 和C2F6产生TFT的良好特性，并且H2等离子体处理可以导致TFT的特性得到改善。
