In some embodiments, a backside annealing process such that a first heat source is placed along a backside of the substrate. In other embodiments, the first heat source is used in combination with an anti-reflection dielectric (ARD) layer is deposited over the substrate. In yet other embodiments, a second heat source is placed along a front side of the substrate in addition to the first heat source placed on the backside of the substrate. In yet other embodiments, a heat shield may be placed between the substrate and the second heat source on the front side of the substrate. In yet further embodiments, a single heat source may be used on the front side of the substrate in combination with the ARD layer. A reflectivity scan may be performed to determine which anneal stage (RTA or MSA or both) to place thermal leveling solution.Type: ApplicationFiled: July 15, 2010Publication date: January 19, 2012Applicant: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chun Hsiung Tsai, Han-Pin Chung, Ming-Hsi Yeh, De-Wei Yu, Kuan-Yu Chen

Publication number: 20120015461Abstract: Projection systems and methods with mechanically decoupled metrology plates according to embodiments of the present invention can be used to characterize and compensate for misalignment and aberration in production images due to thermal and mechanical effects. Sensors on the metrology plate measure the position of the metrology plate relative to the image and to the substrate during exposure of the substrate to the production image. Data from the sensors are used to adjust the projection optics and/or substrate dynamically to correct or compensate for alignment errors and aberration-induced errors. Compared to prior art systems and methods, the projection systems and methods described herein offer greater design flexibility and relaxed constraints on mechanical stability and thermally induced expansion. In addition, decoupled metrology plates can be used to align two or more objectives simultaneously and independently.Type: ApplicationFiled: July 16, 2010Publication date: January 19, 2012Applicant: Azores Corp.Inventors: J.

Publication number: 20120015457Abstract: A method and apparatus (20) for testing the mounting of an integrated circuit (16) on a printed circuit board (12) using a ball grid array comprises measuring the change in height, or drop, of the integrated circuit (16) relative to the printed circuit board (12) following soldering of the ball grid array and comparing the measured drop with a predetermined range. The integrated circuit is deemed to have been successfully mounted to the printed circuit board if the change in height falls within the predetermined range.Type: ApplicationFiled: March 23, 2010Publication date: January 19, 2012Applicant: TWENTY TWENTY VISION LIMITEDInventors: Paul Rawlinson, David Hall

Publication number: 20120006396Abstract: A method to determine the cleanness of a semiconductor substrate and the quantity/density of pin holes that may exist within a patterned antireflective coating (ARC) is provided. Electroplating is employed to monitor the changes in the porosity of the ARC caused by the pin holes during solar cell manufacturing. In particular, electroplating a metal or metal alloy to form a metallic grid on an exposed front side surface of a substrate also fills the pin holes. The quantity/density of metallic filled pin holes (and hence the number of pin holes) in the patterned ARC can then be determined.Type: ApplicationFiled: July 8, 2010Publication date: January 12, 2012Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: John M. Cotte, Laura L. Kosbar, Deborah A. Neumayer, Xiaoyan Shao
