    • A process for prohibiting amino group transport from the top surface of a layered semiconductor wafer to a photoresist layer introduces a thin film oxynitride over the silicon nitride layer using a high temperature step of nitrous oxide (N2O) plus oxygen (O2) at approximately 300° C. for about 50 to 120 seconds. By oxidizing the silicon nitride layer, the roughness resulting from the adverse affects of amino group transport eliminated. Moreover, this high temperature step, non-plasma process can be used with the more advanced 193 nanometer technology, and is not limited to the 248 nanometer technology. A second method for exposing the silicon nitride layer to an oxidizing ambient, prior to the application of antireflective coating, introduces a mixture of N2H2 and oxygen (O2) ash at a temperature greater than or equal to 250° C. for approximately six minutes. This is followed by an O2 plasma clean and/or an Ozone clean, and then the subsequent layering of the ARC and photoresist.
    • 用于禁止从层状半导体晶片的顶表面到光致抗蚀剂层的氨基转移的方法使用一氧化二氮(N 2 O 2 O)的高温步骤在氮化硅层上引入薄膜氧氮化物, 在约300℃下加氧气(O 2 H 2)约50至120秒。 通过氧化氮化硅层,消除了由氨基转移的不利影响产生的粗糙度。 此外,这种高温步骤,非等离子体工艺可以采用更先进的193纳米技术,并不限于248纳米技术。 在施加抗反射涂层之前,将氮化硅层暴露于氧化环境的第二种方法是引入N 2 H 2 O 2和氧的混合物(O 2℃)灰分,温度大于或等于250℃约6分钟。 之后是等离子体清洁和/或臭氧清洁,然后再分层ARC和光致抗蚀剂。

    • A combination of gases including at least a fluorocarbon gas, oxygen, and an inert sputter gas is employed to etch at least one opening into an organic photoresist. The amount of oxygen is controlled to a level that limits conversion of a metallic nitride material in an underlying hard mask layer to a metal oxide, and causes organic polymers generated from the organic photoresist to cover peripheral regions of each opening formed in the organic photoresist. The hard mask layer is etched with a taper by the oxygen-limited fluorine-based etch chemistry provided by the combination of gases. The taper angle can be controlled such that a shrink ratio of the lateral dimension by the etch can exceed 2.0.
