Abstract

PURPOSE:To enable efficient heat radiation and reduction of the size of a multichip LSI package by pressing and fixing a heat sink to a thermally conductive chip carrier secured onto a multilayer wiring substrate. CONSTITUTION:An IC chip 1 is placed on a chip carrier 2, and is connected to a bonding pad 4 via an IC lead 3 onto a multilayer wiring substrate 8. The chip carrier 2 is formed of a material having good thermal conductivity, and is secured to the substrate 8 with four projections. A heat sink 5 provided with a radiation fin 5-1 is held by a holding mechanism 7, and is intimately contacted with the chip carrier 2 via a heat absorber 5-2 provided at one end by the pressing force of a spring 6.
