US Patent 7560302 Semiconductor device fabricating method

To improve the fabrication yield of semiconductor devices. A semiconductor device where a desired number of semiconductor chips are laminated in the thickness direction thereof is fabricated by repeating, an arbitrary number of times such as one time or two or more times, a step of bonding and mounting another support substrate laminate on first bumps exposed by separating and removing one support substrate from a support substrate laminate composite where second bumps of two support substrate laminates including plural semiconductor wafers mounted on support substrates have been made to face each other and are electrically connected.
