Patent number: 9607873Abstract: An apparatus includes a body and a surface for receiving a semiconductor wafer carrier is provided. A nozzle and a venting hole are provided on the surface. The semiconductor wafer carrier has at least one selectively closable capped opening at a bottom, top and/or side surface thereof. The capped opening is configured to couple to, and be accessible by, the nozzle and receive gas output from the nozzle so as to create a substantially oxygen free environment within the semiconductor wafer carrier. The vent hole is configured to allow gas to flow out of the semiconductor wafer carrier. In addition, the apparatus includes a sensor and a controller. The sensor is configured to monitor an ambient condition in the semiconductor wafer carrier, and the controller is configured to adjust a control valve based on the ambient condition so as to control the gas flow or output from the nozzle.Type: GrantFiled: February 7, 2014Date of Patent: March 28, 2017Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.Inventors: Si-Wen Liao, Jia-Wei Xu, Mao-Cheng Lin, Chien-Cheng Wu, Lan-Hai Wang, Ding-I Liu, Fu-Shun Lo

Patent number: 9573144Abstract: A method of forming a coating film over a substrate is provided. The method includes spinning the substrate. The method further includes providing a central coating liquid spray over a central portion of the substrate. The method also includes providing first coating liquid sprays over the substrate. The first coating liquid sprays surround the central coating liquid spray and are spaced apart from the central coating liquid spray by a same first distance.Type: GrantFiled: May 30, 2014Date of Patent: February 21, 2017Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING CO., LTD.Inventors: Lan-Hai Wang, Yong-Hung Yang, Ding-I Liu, Si-Wen Liao, Po-Hsiung Leu, Mao-Cheng Lin

Patent number: 9490152Abstract: A production tool includes a chamber, a heater in the chamber, and a pumping outlet on a side of the heater. A pumping liner is in the chamber and encircling the heater. The pumping liner and the heater have a first gap therebetween and a second gap therebetween. The second gap is different from the first gap, and the second gap is farther away from the first pumping outlet than the first gap.Type: GrantFiled: May 29, 2012Date of Patent: November 8, 2016Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Lan-Hai Wang, Ding-I Liu, Si-Wen Liao, Yong-Hung Yang, Jia-Wei Hsu

Patent number: 9324559Abstract: A multi chamber thin film deposition apparatus and a method for depositing films, is provided. Each chamber includes a three dimensional gas delivery system including process gases being delivered downwardly toward the substrate and laterally toward the substrate. A pumping system includes an exhaust port in each chamber that is centrally positioned underneath the substrate being processed and therefore the gas flow around all portions of the edge of the substrate are equally spaced from the exhaust port thereby creating a uniform gas flow profile which results in film thickness uniformity of films deposited on both the front and back surfaces of the substrate. The deposited films demonstrate uniform thickness on the front and back of the substrate and extend inwardly to a uniform distance on the periphery of the backside of the substrate.Type: GrantFiled: June 21, 2013Date of Patent: April 26, 2016Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Lan Hai Wang, Ding-I Liu, Si-Wen Liao, Po-Hsiung Leu, Yong-Hung Yang, Chia-Ming Tai
