Abstract:
1. A method of manufacturing a semiconductor device including a pickup step of: after dicing a semiconductor wafer of a thickness of 100 μm or less, to which an adhesive sheet is attached, into individual semiconductor chips, vacuuming and holding each semiconductor chip using a vacuuming jig to collect each semiconductor chip from the adhesive sheet, wherein the pickup step further includes: using an upthrow jig so as to upheave the semiconductor device via the adhesive sheet while holding a portion of the adhesive sheet corresponding to a peripheral region of the semiconductor chip using a vacuuming stage; and imparting ultrasonic vibration, having been applied to the upthrow jig, to the semiconductor chip; imparting ultrasonic vibration, having been applied to the upthrow jig, to the semiconductor chip.
