Patent number: 8101018Abstract: In a method for fabricating a semiconductor device and an apparatus for inspecting a semiconductor, laser processing is performed at different laser powers at different positions on a monitor substrate from a plurality of substrates having undergone an SPC step, to form polycrystalline silicon film over the entire area of the substrate. Thereafter, in an optimum power inspection/extraction step, the polycrystalline silicon film formed with varying film quality on the monitor substrate is inspected on inspection equipment to determine the optimum laser power. Then, in a laser processing step, the surface of the subsequent substrates having undergone the SPC step is irradiated with laser at the optimum laser power. Thus, high-quality polycrystalline silicon film is formed over the entire area of the substrate.Type: GrantFiled: March 2, 2005Date of Patent: January 24, 2012Assignee: Sharp Kabushiki KaishaInventor: Yasunobu Tagusa

Patent number: 6587161Abstract: A pixel substrate has a plurality of scanning lines and a plurality of reference signal lines which are arranged parallel with each other. A counter substrate includes a plurality of signal lines. Moreover, the pixel substrate has a connecting line for connecting the plurality of the reference signal lines to each other. The connecting line is provided in each of two regions outside of two sides among the peripheral sides of a region where a plurality of pixel electrodes are formed, the two sides being perpendicular to the reference signal lines. In this structure, a reference signal is input from both ends of the reference signal line. It is therefore possible to provide a liquid crystal display device which reduces the occurrence of a short circuit between the lines on the substrate and decreases the signal delay due to the load capacitance.Type: GrantFiled: April 23, 1999Date of Patent: July 1, 2003Assignee: Sharp Kabushiki KaishaInventors: Tomohiko Yamamoto, Keiichi Tanaka, Naoto Inoue, Kouji Fujiwara, Yasunobu Tagusa
