Publication number: 20240088187Abstract: 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.Type: ApplicationFiled: January 3, 2023Publication date: March 14, 2024Inventors: Chih Cheng Shih, Tsun-Kai Tsao, Jiech-Fun Lu, Hung-Wen Hsu, Bing Cheng You, Wen-Chang Kuo

Patent number: 9075474Abstract: 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.Type: GrantFiled: October 30, 2009Date of Patent: July 7, 2015Assignee: HTC CorporationInventors: Shu-Hsiang Yang, Chih-Chang Hsu, Chung-An Chien, Ming-Jer Yang
