Title: Semiconductor module
Inventor: MURAKAMI MASAHIRO
IPC: H01L25/04
Filed: 2009-02-10
Abstract: <P>PROBLEM TO BE SOLVED: To eliminate the warping accompanying temperature variation of a top plate 5 made of a dissimilar material, and thereby to reduce the defect of mounting of an electronic component 3 when a semiconductor module is mounted on a main substrate.  <P>SOLUTION: The top plate 5, which is arranged opposite a module substrate 1 via the electronic component 3, includes a resin layer 11 and metal layers 12 and 13, and has an insulating property. By the fact that the metal layers 12 and 13 are respectively formed on both sides of the obverse and reverse of the resin layer 11, in a reflow soldering step while mounting the semiconductor module on the main substrate, the warping of the top plate 5 occurring due to the difference in coefficient of thermal expansion between the resin layer 11 and metal layer 12 accompanying temperature variation is canceled by the warping of the top plate 5 occurring due to the difference in coefficient of thermal expansion between the resin layer 11 and metal layer 13, so that the warping of the top plate 5 is eliminated. Consequently, it is possible to avoid a case in which the electronic component 3, which is bonded to the top plate 5 via an adhesive 6, is pressed against the module substrate 1 or lifted due to the warping of the top plate 5.  <P>COPYRIGHT: (C)2010,JPO&INPIT
