  • Patent number: 10304885
    Abstract: The present disclosure is directed to a method for reducing the surface deformation of a color filter after a baking process in an image sensor device. Surface deformation can be reduced by increasing the surface area of the color filter prior to baking. For example, forming a grid structure over a semiconductor layer of an image sensor device, where the grid structure includes a first region with one or more cells having a common sidewall; disposing one or more color filters in a second region of the grid structure; recessing the common sidewall in the first region of the grid structure to form a group of cells with the recessed common sidewall; and disposing another color filter in the group of cells.

  • Patent number: 10086559
    Abstract: A system for online monitoring powder-based 3D printing processes and method thereof are disclosed. A uniform light source having a single wavelength provided by the system is irradiated onto the powder layer before and after applied with glue. Intensities of such reflected images are obtained and subtracted from each other in an image process procedure. A difference obtained through the subtraction is compared with an original 3D model in a computer. If any defect is found such as being larger than a threshold value, the powder-based 3D printing processes will be terminated. Therefore, the technical effects of online printing processes monitoring, time saving and printing resources saving will be achieved.

  • Patent number: 9269857
    Abstract: Disclosed are a method and system for eliminating yellow ring phenomenon occurring on the white light emitting diode (LED) based on a blue light chip exciting yellow phosphor powders and having a packaging surface enclosing thereon. Lightspot images are repeatedly acquired outside the white LED, and then each analyzed to see if the yellow ring still exists on a lightspot. If yes, a further atomization process is performed on the packaging surface of white LED, until the acquired and analyzed image shows no yellow ring exists. A lightspot-by-lightspot basis is used in the yellow ring elimination task. In the image analysis, a look up table may be provided in advanced or established at the same time simultaneously with the yellow ring elimination task. The atomization performed on the lightspot may also consider a width issue.
