Publication number: 20140363966Abstract: 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: ApplicationFiled: August 25, 2014Publication date: December 11, 2014Inventors: Cheng-Chung Lin, Chung-Shi Liu, Meng-Wei Chou, Kuo Cheng Lin, Wen-Hsiung Lu, Chien Ling Hwang, Ying-Jui Huang, De-Yuan Lu
