    Abstract: A two-stage packaging method of image sensors is disclosed. The packaging method includes the following steps: providing a substrate, fixing an image sensor chip on the substrate, fixing a transparent board on the image sensor chip, electrically connecting the image sensor chip and the substrate, forming a first encapsulant lay, and forming a second encapsulant layer. The two-stage packaging method prevents excessive pressure from being generated by formation of the encapsulant layers during the image sensor packaging process. Such excessive pressure, if generated, may result in position shift of the image sensor chip or damage of the bonding wires. The two-stage packaging method can increase the yield of the image sensor packaging process as well as the sensitivity of image sensors, thereby improving the quality and production of image sensor packaging while lowering the manufacturing costs.

    Abstract: A sensor package structure includes a substrate, a sensor chip disposed on the substrate, a plurality of metal wires electrically connecting the substrate and the sensor chip, a glass cover disposed on the sensor chip, and an adhesive layer connecting the glass cover to the substrate. The substrate is made of a material having a coefficient of thermal expansion (CTE) that is less than 10 ppm/° C. The glass cover includes a board body and an annular supporting body connected to the board body. The annular supporting body of the glass cover is fixed onto the substrate through the adhesive layer, so that the glass cover and the substrate jointly surround an enclosed accommodating space. The sensor chip and the metal wires are arranged in the accommodating space, and the sensing region of the sensor chip faces the light-permeable portion of the board body.

    Abstract: A sensor package structure includes a substrate, a sensor chip disposed on the substrate, a plurality of wires electrically connected to the substrate and the sensor chip, a transparent layer facing the sensor chip, a support disposed on the substrate, and a packaging compound disposed on the substrate and covering side edges of the support and the transparent layer. A part of each wire is embedded in the support. A height from the upper surface of the substrate to the top of the support is larger than a height from the upper surface of the substrate to the top of any of the wires. The bottom surface of the transparent layer has a central region facing the sensor chip and a ring-shaped supporting region surrounded by the central region. The support is arranged outside the sensor chip and abuts against the supporting region.
