Patent number: 8823166Abstract: Apparatus and methods for providing solder pillar bumps. Pillar bump connections are formed on input/output terminals for integrated circuits by forming a pillar of conductive material using plating of a conductive material over terminals of an integrated circuit. A base portion of the pillar bump has a greater width than an upper portion. A cross-section of the base portion of the pillar bump may make a trapezoidal, rectangular or sloping shape. Solder material may be formed on the top surface of the pillar. The resulting solder pillar bumps form fine pitch package solder connections that are more reliable than those of the prior art.Type: GrantFiled: August 30, 2010Date of Patent: September 2, 2014Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Cheng-Chung Lin, Chung-Shi Liu, Meng-Wei Chou, Kuo Cheng Lin, Wen-Hsiung Lu, Chien Ling Hwang, Ying-Jui Huang, De-Yuan Lu

Patent number: 8560997Abstract: Among other things, one or more techniques for conditional cell placement are provided herein. In an embodiment, a conditional boundary is created for a first cell. For example, the conditional boundary enables the first cell to be placed relative to a second cell based on a conditional placement rule. In an embodiment, the first cell is placed in a first manner relative to the second cell based in a first scenario. In a second scenario, different than the first scenario, the first cell is placed in a second manner relative to the second cell. In this manner, conditional cell placement is provided, thus providing flexibility and improved layout efficiency with regard to semiconductor fabrication, for example.Type: GrantFiled: July 25, 2012Date of Patent: October 15, 2013Assignee: Taiwan Semiconductor Manufacturing Company LimitedInventors: Ping-Lin Yang, Ming-Zhang Kuo, Cheng-Chung Lin, Jimmy Hsiao, Jia-Rong Hsu
