Abstract

The present invention provides a structure for forming an optical splitting lens. Through changing the material of a lens material layer and the shape of a lens, the light splitting characteristics of different light wave ranges can be obtained, and the requirement from ultraviolet light to infrared light is satisfied. The invention also provides a method for forming an optical splitting lens, through forming different recesses with lens shapes by using crystal orientation etching in a substrate and depositing lens materials in the recesses to form lenses, various optical splitting lenses can be formed conveniently, and the method can be fully compatible with an existing integrated circuit manufacturing process.

Description

technical field [0001] The invention belongs to the technical field of semiconductor integrated circuit manufacturing technology, and in particular relates to a structure and method for forming an optical beam splitting lens. Background technique [0002] Silicon-based optical sensors (CCD / CIS, charge-coupled device / CMOS image sensor) are the mainstream of optical image sensors. In order to obtain a color image, an optical splitter lens is required to split the light. At present, optical splitter lenses are all formed during packaging, can only reflect light of a specific wavelength, and are not compatible with existing integrated circuit manufacturing processes. As the size of the sensor continues to shrink, the size of the lens must also shrink accordingly, which puts forward higher requirements for materials and processes. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects, and proposes a structure and me...
