Abstract: Apparatus for detecting a defect in the outer peripheral edge of a wafer includes a rotary mechanism by which the wafer can be rotated, a wafer edge contact device, and a controller. The wafer edge contact device includes a string that is pressed against the edge of the wafer. One end of the string is fixed in place, and a sensor is operatively associated with the other end of the string so as to sense movement of the other end of the string. This other end of the string will be pulled by a defect at the outer peripheral edge of the wafer when the wafer is rotated. Thus, a defective edge of the wafer can be detected before/after the wafer is processed. Accordingly, the wafer can be prevented from being further damaged, wafer particles are prevented from polluting the fabricating equipment, and the operating efficiency and productivity of the fabricating equipment are enhanced.

Abstract: Disclosed is an image sensor module applied to a thin image sensor device. A method of fabricating the image sensor module consists of the steps of forming a bump on a glass, attaching the glass to an image sensor at a wafer level, and firstly and secondly dicing the resulting structure. Therefore, the present invention is advantageous in that fabrication of an inferior image sensor module is reduced, thus improving a quality of the image sensor module, productivity of the image sensor module is improved because the image sensor module is fabricated at the wafer level, and a gold wiper process is omitted, thus reducing fabrication costs of the image sensor module.

Abstract: Disclosed herein is a chip on board lead package for optical mice and lens cover for the same. A semiconductor chip on board package for optical mice has a board, a semiconductor chip, at least one circuit pattern, at least one bonding wire, and a lens cover. The board has top and bottom surfaces, and a pair of via holes. The semiconductor chip is attached to a center portion on the top surface of the board and provided with a plurality of electrode terminals. The circuit pattern is formed on the top surface of the board. The bonding wire electrically connects the electrode terminals of the semiconductor chip with the circuit pattern. The lens cover encloses the top surface of the board and has a lens disposed on the same axis as that of the semiconductor chip, a plurality of electrode pins formed at positions of the lens cover corresponding to the positions of the via holes in the board to be integrated with the lens cover, and an opening formed in a center portion within the lens cover.
