  • Publication number: 20200388497
    Abstract: First, second, and third trenches are formed in a layer over a substrate. The third trench is substantially wider than the first and second trenches. The first, second, and third trenches are partially filled with a first conductive material. A first anti-reflective material is coated over the first, second, and third trenches. The first anti-reflective material has a first surface topography variation. A first etch-back process is performed to partially remove the first anti-reflective material. Thereafter, a second anti-reflective material is coated over the first anti-reflective material. The second anti-reflective material has a second surface topography variation that is smaller than the first surface topography variation. A second etch-back process is performed to at least partially remove the second anti-reflective material in the first and second trenches. Thereafter, the first conductive material is partially removed in the first and second trenches.

  • Publication number: 20190244068
    Abstract: A method, apparatus, and computer readable medium are provided. The method includes receiving, from a terminal, target information to be coded in a graphic identification code, and personalized effect information. First lattice data is generated according to the target information. Each data point in the first lattice data is processed according to first-type effect information included in the personalized effect information, to obtain second lattice data. The second lattice data is processed according to second-type effect information included in the personalized effect information, to obtain the graphic identification code.

  • Patent number: 10311348
    Abstract: A graphic identification code generation method and apparatus are provided. The method includes receiving, from a terminal, target information and personalized effect information for a graphic identification code. The target information represents information displayed after the graphic identification code is scanned, and the personalized effect information is used to represent a display effect of the graphic identification code. Lattice data of the graphic identification code is generated according to the target information, and the graphic identification code is generated according to the lattice data and the personalized effect information.

  • Patent number: 6776483
    Abstract: A pair of spectacles includes a rim, two angle adjusting devices each mounted on the rim, and two temples each mounted on a respective angle adjusting device. Each of the angle adjusting devices includes a connecting member formed with a locking pawl, and a pivot member pivotally mounted on the connecting member and formed with locking grooves. Thus, the locking pawl of the connecting member is detachably locked in either one of the locking grooves of the pivot member, so that the included angle between the connecting member and the pivot member is changed arbitrarily so as to adjust the angle of the rim relative to the temples.
