Patent ID: 7648889

Claim:
A production method for devices, comprising: a preparing process for preparing a wafer having plural semiconductor chips which have electronic circuits formed on circuit surfaces of the semiconductor chips and which are partitioned by predetermined division lines on a surface of the wafer, and for preparing other divided plural semiconductor chips having electronic circuits formed on circuit surfaces of the other semiconductor chips; a bonding process for placing the circuit surfaces of the other semiconductor chips onto the circuit surfaces of the semiconductor chips of the wafer and bonding the other semiconductor chips to the semiconductor chips of the wafer; a semiconductor chip grinding process for grinding rear surfaces of the other semiconductor chips by a grinding apparatus while the wafer having the other semiconductor chips bonded thereon is held such that the rear surface of the wafer faces a chuck table of the grinding apparatus; a resin filling process for filling a resin on the surface of the wafer having the other semiconductor chips bonded thereon so that a surface of the resin at least corresponds with the rear surfaces of the other semiconductor chips; a wafer grinding process for grinding the rear surface of the wafer having the resin filled on the surface by a grinding apparatus while the wafer is held such that the surface of the wafer on which the resin is filled faces a chuck table of the grinding apparatus; a wafer supporting process for supporting one of the surface and the rear surface of the wafer by a supporting member; and a dividing process for dividing the wafer along the predetermined division lines while the wafer, which is processed by the bonding process, the semiconductor chip grinding process, the resin filling process, the wafer grinding process, and the wafer supporting process, is supported by the support member, thereby obtaining devices having the semiconductor chips and the other semiconductor chips bonded on the semiconductor chips.
