Abstract

PURPOSE:To improve connecting operability in an electric connection of various types of packages, etc., and to prevent the package from swelling or cracking by laminating a conductive metal layer, a low melting point metal material layer on an insulating substrate. CONSTITUTION:A copper layer 3a of conductive metal is provided by vacuum vapor on an insulating substrate 1, and an indium layer 3a of low melting point metal material is laminated by vacuum depositing in response to a conductor pattern on a layer 2. When an IC chip 4 or the like is placed on the layer 3a, heated to approx. 160 deg.C, and then cooled, the chip 4 is electrically and mechanically rigidly connected to the substrate 1 through the aluminum electrode 4a of the chip 4 and a conductor pattern. With this configuration, connecting operability in the electric connection of various packages is enhanced, and it can prevent the package from swelling or cracking.
