摘要： A cooling structure for cooling a multichip module for effectively removing heat generated from integrated circuit chips. A suction plate formed with minute grooves on one of its surfaces is disposed between each integrated circuit chip and an associated cooling block and is brought into contact at a grooved surface with the integrated circuit chip through a layer of a liquid such as silicone oil interposed therebetween, thereby producing negative hydrostatic pressure by capillary action of the minute grooves. The suction plate has a thickness small enough to be bent under influence of the negative hydrostatic pressure to follow a warping of the integrated circuit chip, so that the clearance between the opposing surfaces of the suction plate and the integrated circuit chip can be minimized. Thus, an integrated circuit chip cooling device of surface-to-surface contact type operable with a low thermal resistance is provided, which can improve the maintainability and reliability without sacrificing the cooling efficiency.

摘要： A semiconductor integrated circuit device is equipped with a cooling system which serves to cool a plurality of integrated circuit chips mounted on a circuit board. The cooling system is kept in contact with the upper surfaces of the plurality of integrated circuit chips. A chip surface arranging plate of uniform thickness is formed with apertures smaller than the integrated circuit chips mounted on the circuit board. The cooling system is fixed on the chip surface arranging plate. The upper surfaces of the integrated circuit chips are substantially kept flush by the chip surface arranging plate. Further, the integrated circuit chips are thermally joined to the cooling system so that heat generated by the integrated circuit chips is removed by the cooling system. The plurality of integrated circuit chips are joined to the chip surface arranging plate by applying a vacuum that causes suction of air through the apertures formed in the chip surface arranging plate. Thereafter, the cooling system is fixed to the chip surface arranging plate.

摘要： A structure for connecting an integrated circuit chip to a wiring substrate which implements high-density packaging, high-density connection, high-speed signal transmission, and low cost. An integrated circuit is connected to a wiring substrate by means of flip-chip die bonding using an adhesive film. A direct through-hole connection is formed directly below a connecting pad so as to pass through the adhesive film and the wiring substrate. This direct through-hole connection directly connects the connecting pad to the wire. As a result of reduced area and thickness of the chip, the chip is mounted in high density, and high-density inputs and outputs are implemented by means of minute two-dimensional connections. Short wire connections directly connected to the chip permit high speed signal transmission, and high reliability is ensured by the dispersion of stress. Low-cost packaging can be effected by simple processes and facilities.
