Patent number: 9287154Abstract: Embodiments of an ultraviolet (UV) curing system for treating a semiconductor substrate such as a wafer are disclosed. The curing system generally includes a processing chamber, a wafer support for holding a wafer in the chamber, a UV radiation source disposed above the chamber, and a UV transparent window interspersed between the radiation source and wafer support. In one embodiment, the wafer support is provided by a belt conveyor operable to transport wafers through the chamber during UV curing. In another embodiment, the UV radiation source is a movable lamp unit that travels across the top of the chamber for irradiating the wafer. In another embodiment, the UV transparent window includes a UV radiation modifier that reduces the intensity of UV radiation on portions of the wafer positioned below the modifier. Various embodiments enhance wafer curing uniformity by normalizing UV intensity levels on the wafer.Type: GrantFiled: June 1, 2012Date of Patent: March 15, 2016Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Ming Huei Lien, Chia-Ho Chen, Shu-Fen Wu, Chih-Tsung Lee, You-Hua Chou

Patent number: 9218998Abstract: An electrostatic chuck for clamping a warped workpiece has a clamping surface comprising a dielectric layer. The dielectric layer has a field and one or more zones formed of differing dielectric materials. One or more electrodes are coupled to a power supply, and a controller controls a clamping voltage supplied to the one or more electrodes via the power supply. An electrostatic attraction force associated with each of the field and one or more zones of the dielectric layer of the electrostatic chuck is induced, wherein the electrostatic attraction force varies based on the dielectric material of each of the field and one or more zones. The electrostatic attraction force is greater in the one or more zones than in the field, therein attracting warped regions of the workpiece to the clamping surface and clamping the warped workpiece to the clamping surface across a surface of the warped workpiece.Type: GrantFiled: October 3, 2014Date of Patent: December 22, 2015Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Chia-Ho Chen, Ming Huei Lien, Shu-Fen Wu, Chih-Tsung Lee, You-Hua Chou

Publication number: 20130239889Abstract: A semiconductor manufacturing tool and method for operating the tool are provided. The semiconductor manufacturing tool includes a process chamber in which plasma operations or ion etching operations are carried out and a valve assembly for opening and closing a valve that provides for loading and unloading substrates into and out of, the semiconductor manufacturing tool. While a processing operation is being carried out in the chamber, a valve assembly purge operation also takes place. The valve assembly purge operation involves inert gases being directed to the valve assembly area to prevent the buildup of particles and contaminating films in the valve assembly. Because the valve assembly is maintained in a clean condition, particle contamination is reduced or eliminated.Type: ApplicationFiled: March 14, 2012Publication date: September 19, 2013Applicant: TAIWAN SEMICONDUCTOR MANUFACTURING CO., LTD.Inventors: Ming Huei LIEN, Chia-Ho CHEN, Shu-Fen WU, Chih-Tsung LEE, You-Hua CHOU
