  • Patent number: 9184331
    Abstract: A method for reducing the tilt of an optical unit during manufacture of an image sensor includes the steps of: providing a semimanufacture of the image sensor, carrying out a preheating process, carrying out an adhesive application process, carrying out an optical unit mounting process, and carrying out a packaging process. Due to the preheating process, the semimanufacture will be subjected to a stabilized process environment during the adhesive application process and the optical unit mounting process, so as for the optical unit to remain highly flat once attached to the semimanufacture. The method reduces the chances of tilt and crack of the optical unit and thereby contributes to a high yield rate.

  • Patent number: 8969120
    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.

  • Patent number: 8103159
    Abstract: The present invention is directed to a flashing control method for a digital camera. Indices respectively corresponding to sensitivity values are firstly determined. Subsequently, main-flash intensities are respectively obtained with respect to the sensitivity values such that their target brightness values are substantially the same after exposure, thereby constructing an energy table. Further, a predetermined preflash is fired to obtain a corresponding preflash brightness value with respect to each distinct distance. Main-flash indices are then respectively obtained according to maximum main-flash intensity and the energy table with respect to the distinct distances such that the target brightness values are substantially the same after exposure, thereby constructing a preflash table. During picture capturing, the main-flash intensity is obtained according to the preflash brightness value and the preflash table.

    Abstract: A thin film etching method is provided, which is used for manufacturing semiconductor device or thin film transistor (TFT) array and through which no undercut may be presented or a good after-etching shape may be achieved with respect to a thin film thus etched. The thin film etching method is performed in a two-stage manner by an etchant and between the two stages a photoresist removing process is inserted where another etchant is used. With execution of the photoresist removing process, the thin film may have an increased contact area with the etchant. As such, any undercut or undesired after-etching shape existed in the thin film etched by the prior art may be eliminated or improved.
