Abstract:
A semiconductor device production apparatus comprising:a base; a cover on the base forming an enclosure; a dicing unit which dices a wafer stuck to a tape stretchable by a physical process; a physical process unit which stretches the tape by performing the physical process on the tape by physical process means; a grinding unit which grinds a rear surface of the wafer by a grinder, with the tape stuck to the wafer; the dicing unit, physical process unit and grinding unit located in the enclosed with the physical process unit located between the dicing unit and the grinding unit; and an infrared camera disposed on the dicing unit to pick up an image in accordance with reflected infrared rays from the wafer when infrared rays are emitted to the wafer, so that a dicing line formed on the wafer can be recognized from the rear surface of the wafer without reversing a direction of the wafer during the dicing and grinding of the wafer.
