发明名称 Etch-enhanced technique for lift-off patterning
摘要 An enhanced process forming a material pattern on a substrate deposits the material anisotropically on resist material patterned to correspond to an image of the material pattern. The material is etched isotropically to remove a thickness of the material on sidewalls of the resist pattern while leaving the material on a top surface of the resist pattern and portions of the surface of the substrate. The resist pattern is removed by dissolution thereby lifting-off the material on the top surface of the resist pattern while leaving the material on the substrate surface as the material pattern. Alternately, a first material layer is deposited on the resist pattern and a second material layer is deposited and planarized. The second material layer is etched exposing the first material while leaving the second material in features of the resist pattern. The first material and the resist are removed leaving the first material pattern.
