    摘要: A manufacturing method of a chip package includes the following steps. A light transmissive substrate is bonded to a first surface of a wafer, such that a dam element between the light transmissive substrate and the wafer covers a conductive pad of the wafer. A second surface of the wafer facing away from the first surface is etched, such that a hollow region and a trench selectively communicated with the hollow region are synchronously formed in the wafer. A first isolation layer on the conductive pad is etched to expose the conductive pad through the hollow region.

    摘要: A chip package including a substrate is provided. The substrate has a first surface and a second surface opposite thereto. The substrate includes a sensing region. A cover plate is on the first surface and covers the sensing region. A shielding layer covers a sidewall of the cover plate and extends towards the second surface. The shielding layer has an inner surface adjacent to the cover plate and has an outer surface away from the cover plate. The length of the outer surface extending towards the second surface is less than that of the inner surface extending towards the second surface, and is not less than that of the sidewall of the cover plate. A method of forming the chip package is also provided.

    摘要: An embodiment of this invention provides a separation apparatus for separating a stacked article, such as a semiconductor chip package with sensing functions, comprising a substrate and a cap layer formed on the substrate. The separation apparatus comprises a vacuum nozzle head including a suction pad having a top surface and a bottom surface, a through hole penetrating the top surface and the bottom surface of the suction pad, and a hollow vacuum pipe connecting the through hole to a vacuum pump; a stage positing under the vacuum nozzle head and substantially aligning with the suction pad; a control means coupling to the vacuum nozzle head to lift upward or lower down the vacuum nozzle head; and a first cutter comprising a first cutting body and a first knife connecting to the first cutting body. The cap layer is pressed against by the bottom surface of the suction pad and sucked by the suction pad of the vacuum nozzle head after the vacuum pump begins to vacuum the air within the hollow vacuum pipe and the through hole. Then, the first cutter cuts into the interface between the substrate and the cap layer, and the cap lay is separated from the substrate by the suction force of the vacuum nozzle head and the lift force generated by the upward movement of the vacuum nozzle head.
