  • Publication number: 20240088187
    Abstract: Trenches in which to form a back side isolation structure for an array of CMOS image sensors are formed by a cyclic process that allows the trenches to be kept narrow. Each cycle of the process includes etching to add a depth segment to the trenches and coating the depth segment with an etch-resistant coating. The following etch step will break through the etch-resistant coating at the bottom of the trench but the etch-resistant coating will remain in the upper part of the trench to limit lateral etching and substrate damage. The resulting trenches have a series of vertically spaced nodes. The process may result in a 10% increase in photodiode area and a 30-40% increase in full well capacity.

  • Patent number: 11929000
    Abstract: The display system comprising a main control module and a display module is provided. The main control module comprises a display driving circuit and a timing control circuit. The display driving circuit is used to output a display driving signal. The timing control circuit is coupled to the display driving circuit to receive the display driving signal, and convert the display driving signal into a digital signal. The display module comprises a first display panel to an N-th display panel, coupled to the timing control circuit and receiving the digital signal, so as to display corresponding multimedia content according to the digital signal, wherein N is a positive integer greater than 1, and the main control module is independently coupled to the display module.

  • Patent number: 7886234
    Abstract: Methods for generating an embedded target image to be stored in a non-volatile memory device of an embedded system as firmware thereof are disclosed. A graphical user interface (GUI) editor is generated to facilitate a user in providing settings information for multiple pins of a chip installed in the embedded system. Source code is generated in response to operating results of the user of the GUI editor. Linking an object file compiled from the generated source code generates the embedded target image.

  • Publication number: 20080244301
    Abstract: A real-time clock (RTC) correction method is provided. Correction data for correcting an RTC of the electronic device is calculated and stored before a power off operation of an electronic device. When the power off operation is performed between two correction operations of the RTC, the period between the two correction operations of the RTC is also calculated. The RTC is corrected utilizing the correction data and the period.
