Filed: 1991-12-27
Abstract: PURPOSE:To provide a lens processing method which makes it possible to process a thick lens with comparatively high precision on the surface of a substrate for semiconductor devices, using a sheet mask by a photolithography process. CONSTITUTION:A photoresist film 5 is formed on the surface of a substrate 1 of InP, etc., to be processed. After it is processed into a specified shape by exposure, the substrate surface is wet-etched by a hydrogen bromide group water solution using the resist film as a mask. Then the solution creeps into the lower side of the resist film and the side walls of a protruding part la are etched. And the substrate l is drawn up from the solution, and the resist film is removed. After that, a series of treatments of forming a resist film again on the substrate surface, exposing it using the same mask, patterning, and wet etching are repeated, and the substrate surface is processed into the shape of a protrusion. When the resist film is removed and the substrate is dipped into an etching solution after that, the stepped parts of the surface of the protruding part 1a disappear and it is processed into a smooth lenslike shape. And it becomes possible to perform high-precision processing of a thick lens by increasing the number of the series of treatments repeated and reducing the each-time etching quantity.
