Inventor: TAKE MORIO
IPC: H01L21/60
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To dissipate generated heat by removing the resin overblown on the surface of a trapezoidal projection by a sandblasting method to expose parts of the surface of a metal plate corresponding to the area for mounting heat radiation bumps on a lower face of a semiconductor chip. SOLUTION: The resin overblown when heated on a trapezoidal projection for mounting a semiconductor chip having a double-sided copper-clad plate and/or on a copper foil in a through hole section (d) is removed preferably by a sandblasting method. Then, the whole surface is coated with plating resist except for at least the surface of the trapezoidal projection on the surface which becomes a semiconductor chip mounting section, a circuit to connect flip chip bumps to, and the surfaces of ball pads on the rear face to which solder balls are bonded. And then, nickel plating and gold plating are applied to complete a printed wiring board. The heat generated from the semiconductor chip is dissipated into the air on the upper face and, at the same time, heat is transmitted to a metal core through bumps formed on a lower face.  Due to this structure, a heat dissipation property, a heat-resisting property after absorption of moisture, and the adhesion of the solder balls can be increased.
