  • Patent number: 6686606
    Abstract: The Mo or MoW composition layer has a low resistivity of less than 15 &mgr;&OHgr;cm and is etched to have a smooth taper angle using an Al alloy enchant or a Cr enchant, and the Mo or MoW layer is used for a wiring of a display or a semiconductor display along with an Al layer or 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 be 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 polymer layer, an etch gas system using CF4+O2 can prevent the etch of the Mo or MoW alloy layer, and an etch gas of SF6+HCl (+He) or SF6+Cl2 (+He) can form the edge profile of contact holes to be smoothed.
