  • 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.

  • Publication number: 20210214865
    Abstract: This disclosure relates to techniques for designing and manufacturing an elastic fabric, and fabric manufactures therefrom. An example method includes (i) determining a density ratio of the elastic fabric based on a set of rules; (ii) determining a weft density of a weft yarn of the elastic fabric based on the set of rules and the density ratio; (iii) determining a warp density of a warp yarn of the elastic fabric based on the density ratio, the weft density, and the set of rules; (iv) forming warp yarns of the elastic fabric based on the warp density; and (v) forming weft yarns of the elastic fabric based on the weft density. Example multi-directional elastic woven fabrics may have a density ratio of the elastic fabric from a range of 1.1 to 2.625, depending on the weaving pattern and a set of rules disclosed here.

  • Patent number: 9075474
    Abstract: A portable electronic device including a touch screen, a micro processing unit, a central processor and a display is provided. The central processor can operate in a normal operation mode or a sleep mode. The touch screen overlays the display, and includes a first touch area, a second touch area and at least one electrode. When the central processor operates in the sleep mode and one of the first and second touch areas senses a touch, the at least one electrode generates a touch signal. The micro processing unit determines whether the touch is sensed by the first or the second touch area according to the touch signal. If the touch is sensed by the second touch area, the micro processing unit outputs a wake-up signal to the central processing unit, so as to switch the central processor from the sleep mode to the normal operation mode.

  • Publication number: 20130108795
    Abstract: A hydrophobic auxiliary, a hydrophilic auxiliary and a penetrant agent are applied to manufacture a fabric. Both hydrophilicity and hydrophobicity are thus obtained at the same time for the fabric. Water absorbed by the fabric is spread in a stereo way. Conclusively, hygroscopicity is kept with a constant function of quick drying.
