3D LITHOGRAPHY WITH LASER BEAM WRITER FOR MAKING HYBRID SURFACES |
摘要 |
A method of etching a feature in a surface of a substrate. The substrate is provided. A photoresist layer is formed on the surface of the substrate. A thickness profile of the formed photoresist layer is determined. A grayscale scanning pattern is determined based on the feature and the thickness profile of the photoresist layer. The determined grayscale scanning pattern is laser written on the photoresist layer to expose a portion of the photoresist layer. The exposed portion of the photoresist layer is removed to form a grayscale pattern in the photoresist layer. The photoresist layer and the surface of the substrate are etched to form the feature in the surface of the substrate.
