摘要
The present invention relates to a manufacturing method of a camera window and a camera window manufactured thereby. The manufacturing method of a camera window formed with a transmission portion on a central portion thereof and with a pattern around the transmission portion comprises the following steps of: forming a mask layer for cell unit pattern processing on a front surface or both surfaces of disk glass; forming a pattern layer by a cell unit on the disk glass by patterning the mask layer for pattern processing; forming a back pattern in a cell unit on the back surface of the disk glass by an etching process by using the pattern layer as a mask; removing the mask layer for pattern processing and forming a mask layer for shape processing on the front surface and the back surface of the disk glass formed with the back pattern; shape-processing the disk glass formed with the back pattern by a cell unit by patterning the mask layer for shape processing; removing the mask layer for shape processing and strengthening the disk glass formed with the back pattern; forming a functional layer in a cell unit on the back surface or both surfaces of the disk glass formed with the back pattern; and forming a camera window by separating the disk glass formed with the back pattern into cell units. According to the present invention, a back pattern and a single deposition layer are formed on a back surface of a glass substrate to increase reflectance and refractive index, thereby enabling recognition of a clearer pattern line. Also, it is possible to simplify an entire process and reduce process cost.;COPYRIGHT KIPO 2018
