Patent number: 10700033Abstract: The present disclosure relates a method of forming an integrated chip packaging device. In some embodiments, the method may be performed by forming a conductive trace on a surface of a packaging component. The conductive trace has an angled surface defining an undercut. A molding material is deposited over an entirety of the conductive trace and within the undercut. The molding material is removed from an upper surface of the conductive trace. The molding material has a sloped outermost sidewall after removing the molding material from the upper surface. A solder region is formed on the upper surface of the conductive trace.Type: GrantFiled: August 13, 2018Date of Patent: June 30, 2020Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Chang-Chia Huang, Tsung-Shu Lin, Ming-Da Cheng, Wen-Hsiung Lu, Bor-Rung Su
