Patent number: 9026971Abstract: The present disclosure relates to a method and apparatus for forming a multiple patterning lithograph (MPL) compliant integrated circuit layout by operating a construction validation check on unassembled IC cells to enforce design restrictions that prevent MPL conflicts after assembly. In some embodiments, the method is performed by generating a plurality of unassembled integrated circuit (IC) cells having a multiple patterning design layer. A construction validation check is performed on the unassembled IC cells to identify violating IC cells having shapes disposed in patterns comprising potential multiple patterning coloring conflicts. Design shapes within a violating IC cell are adjusted to achieve a plurality of violation free IC cells. The plurality of violation free IC cells are then assembled to form an MPL compliant IC layout. Since the MPL compliant IC layout is free of coloring conflicts, a decomposition algorithm can be operated without performing a post assembly color conflict check.Type: GrantFiled: January 7, 2014Date of Patent: May 5, 2015Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Chien Lin Ho, Chin-Chang Hsu, Hung Lung Lin, Wen-Ju Yang, Yi-Kan Cheng, Tsong-Hua Ou, Wen-Li Cheng, Ken-Hsien Hsieh, Ching Hsiang Chang, Ting Yu Chen, Li-Chun Tien

Patent number: 8511958Abstract: A screw with double notches includes a head portion, a shank portion extended outward from the head portion, a threaded section spirally surrounded on the shank portion. Wherein, a raw section on the shank portion is provided with a cambered surface formed integral with the shank portion in cross-section, and a notched section relative to the raw section has two cutting notches separately depressed into the shank portion and disposed near an end of the shank portion, thereby forming a protrudent part between the two cutting notches. By means of the cooperation of the cutting notches and the raw section, the cutting capability and the removal of debris are increased so that a fastened object is prevented from split. Thereby, the drilling speed is promoted, and the effort to rotate the screw is lessened. While the supporting strength of the screw is improved, the screw does not break easily while screwing.Type: GrantFiled: November 23, 2010Date of Patent: August 20, 2013Assignee: Essence Method Refine Co., Ltd.Inventor: Ching-Hsiang Chang

Patent number: 8348573Abstract: A versatile fastener including at least two flat areas formed on a cutting part, and an accommodating area disposed between any two of the flat areas. At least two cutting faces are convergent to form the accommodating area, and first and second cutting edges are respectively formed at a connection between each cutting face and flat area. In operation, the flat areas facilitate the first and the second cutting edges to promote a stable balance with the object, thereby allowing the debris to be swiftly guided out of the accommodating areas. Consequently, it is difficult to crack the object while imparting forces thereon, so as to lower the screwing resistance and the fastening torque as well as increase the combining efficiency.Type: GrantFiled: March 26, 2010Date of Patent: January 8, 2013Assignee: Essence Method Refine Co., Ltd.Inventor: Ching-Hsiang Chang
