摘要:
A semiconductor chip having an adhesive layer previously formed on an element forming surface thereof and having a bump exposed from the surface of the adhesive layer is wire-bonded to a printed circuit board. Another semiconductor chip is stacked on the above semiconductor chip with the adhesive layer disposed therebetween and is wire-bonded to the printed circuit board by wire bonding. Likewise, at least one semiconductor chip is sequentially stacked on the thus attained semiconductor structure to form a stack MCP.

摘要:
A manufacturing method of a semiconductor device to electrically connect a semiconductor chip and a wiring board via a first bump electrode, at least one of the semiconductor chip and the wiring board having a second bump electrode or a connection electrode, the method includes: collectively performing flip chip bonding of the semiconductor chip to the wiring board and resin sealing processing between the semiconductor chip and the wiring board; wherein the collective processing includes controlling viscosity of a sealing resin with ultrasonic vibration so that the first bump electrode penetrates the sealing resin; and using the ultrasonic vibration to electrically connect the first bump electrode to the second bump electrode when at least one of the semiconductor chip and the wiring board has the second bump electrode, or using the ultrasonic vibration to electrically connect the first bump electrode to the connection electrode when at least one of the semiconductor chip and the wiring board has the connection electrode.

摘要:
A bump is formed on at least one of a semiconductor chip and printed circuit board. A sealing material is applied to the surface of one of the semiconductor chip and printed circuit board. The printed circuit board is flip-chip-connected to the semiconductor chip via the sealing material while ultrasonic waves are applied to the printed circuit board to promote bonding by the bump.
