Abstract

A manufacturing method of a chip package includes patterning a wafer to form a scribe trench, in which a light-transmissive function layer below the wafer is in the scribe trench, the light-transmissive function layer is between the wafer and a carrier, and a first included angle is formed between an outer wall surface and a surface of the wafer facing the light-transmissive function layer; cutting the light-transmissive function layer and the carrier along the scribe trench to form a chip package that includes a chip, the light-transmissive function layer, and the carrier; and patterning the chip to form an opening, in which the light-transmissive function layer is in the opening, a second included angle is formed between an inner wall surface of the chip and a surface of the chip facing the light-transmissive function layer, and is different from the first included angle.
