Polysilanes are a class of Si-Si backbone polymers that have been demonstrated to function as high resolution positive resists with excellent uv sensitivity. These materials have a unique photochemistry with high quantum yields and nonlinear bleaching. Polysilanes serve as excellent RIE barriers for bilevel resist applications because a protective layer of SiO2 is formed during exposure to an oxygen plasma. Aliphatic polysilanes have been applied to full wafer mid-uv lithography with 0.75 μm resolution.
