Abstract:
A semiconductor-chip supporting substrate for packaging comprising:an insulating supporting substrate having at least one through-hole as a vent hole, said through-hole being disposed directly under a semiconductor chip and defining an inner side surface of the substrate;at least two wirings being disposed on one surface of said insulating supporting substrate and having a semiconductor chip mounting region; andan insulating film adhesive material provided on the surface of said semiconductor chip mounting region,wherein said insulating film adhesive material has a glass transition temperature of 100.degree. C. or above and a residual volatile component of 2.0% (weight by weight) or less at the time when a semiconductor chip is mounted via the insulating film adhesive material; andwherein a bottom surface of the insulating film adhesive material, said inner side surface of said substrate and an inner side surface of said wirings form an empty space therein which communicates to an open air through said through-hole.
