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.

Abstract: An optical chip package is provided. The optical chip package includes a first transparent substrate, a second transparent substrate, and a spacer layer. The first and second transparent substrates each has a first surface and a second surface opposite the first surface. The first transparent substrate has a thickness that is different than that of the second transparent substrate. The second transparent substrate is disposed over the first transparent substrate, and the spacer layer is bonded between the second surface of the first transparent substrate and the first surface of the second transparent substrate. The recess region extends from the second surface of the second transparent substrate into the first transparent substrate, so that the first transparent substrate has a step-shaped sidewall. A method of forming an optical chip package is also provided.

Abstract: A chip package includes a chip, an adhesive layer, and a dam element. The chip has a sensing area, a first surface, and a second surface that is opposite to the first surface. The sensing area is located on the first surface. The adhesive layer covers the first surface of the chip. The dam element is located on the adhesive layer and surrounds the sensing area. The thickness of the dam element is in a range from 20 μm to 750 μm, and the wall surface of the dam element surrounding the sensing area is a rough surface.

Abstract: A chip package includes a chip, a first adhesive layer, a second adhesive layer, and a protection cap. The chip has a sensing area, a first surface, a second surface that is opposite to the first surface, and a side surface adjacent to the first and second surfaces. The sensing area is located on the first surface. The first adhesive layer covers the first surface of the chip. The second adhesive layer is located on the first adhesive layer, such that the first adhesive layer is between the first surface and the second adhesive layer. The protection cap has a bottom board and a sidewall that surrounds the bottom board. The bottom board covers the second adhesive layer, and the sidewall covers the side surface of the chip.
