Patent ID: 7060528

Claim:
A method comprising: performing wire bonding and thereby forming stud bumps on electrodes of semiconductor elements of a wafer; temporarily compression-bonding said semiconductor elements and an interposer, by applying a first pressure and heat at a first temperature, such that said semiconductor elements and said interposer are brought into contact with an insulative resin sheet positioned therebetween; and curing insulative resin of said insulative resin sheet by applying a second pressure and heat at a second temperature, with said second pressure being greater than said first pressure and said second temperature being greater than said first temperature, whereby said wafer and said interposer are finally compression-bonded to each other such that individual ones of said electrodes and individual electrodes of said interposer become bonded to each other, respectively, so as to form a bonded unit; and dicing said bonded unit such that said bonded unit is cut and separated into individual chips for semiconductor devices, with each of said chips including one of said semiconductor elements, wherein grooves are provided in at least one of said wafer and said interposer coincident with lines along which said bonded unit is diced, and wherein applying said second pressure and heat at said second temperature results in some of said insulative resin flowing in said grooves so as to provide a uniform flow of said insulative resin.
