Publication number: 20090001604Abstract: An oxide layer and a metal layer composed of a gold- or platinum-group metal are formed in the stated order on a substrate. A wiring body having a wiring layer, insulating layer, via, and electrode is formed on the metal layer. A semiconductor element is then connected as a flip chip via solder balls on the wiring body electrode, and underfill is introduced between the semiconductor element and the wiring body. Subsequently, a sealing resin layer is formed so as to cover the semiconductor element and the surface of the wiring body on which the semiconductor element is mounted, thus producing a semiconductor package. A high-density, detailed, thin semiconductor package can thereby be realized.Type: ApplicationFiled: March 1, 2006Publication date: January 1, 2009Inventors: Daisuke Tanaka, Shintaro Yamamichi, Hideya Murai, Tadanori Shimoto, Kaichirou Nakano, Katsumi Maeda, Katsumi Kikuchi, Yoichiro Kurita, Kouji Soejima
