Patent ID: 7445964

Claim:
A semiconductor device manufacturing method comprising: arranging, on a base plate, a plurality of semiconductor structures each including a semiconductor substrate and a plurality of connection pads, such that the semiconductor structures are separated from each other, and arranging at least one insulating sheet member having opening portions at positions corresponding to the semiconductor structures, the at least one insulating sheet member comprising a lower sheet member and an upper sheet member provided on the lower sheet member; heating and pressing the insulating sheet member from an upper side of the insulating sheet member to melt and set the insulating sheet member between the semiconductor structures; forming at least one layer of upper interconnections, each of which has a connection pad portion and is connected to a corresponding one of the connection pads of one of the semiconductor structures so as to arrange the connection pad portion on the insulating sheet member; and cutting the insulating sheet member between the semiconductor structures to obtain a plurality of semiconductor devices, in each of which the connection pad portion of at least one of the upper interconnections is arranged on the insulating sheet member.
