Abstract

To improve the reliability and yield of a thin-type semiconductor device as used for a stack-type flash memory, the semiconductor device is manufactured by upheaving each of semiconductor chips (semiconductor devices) obtained by dicing a semiconductor wafer on an adhesive sheet from a backside via the adhesive sheet using an upthrow jig to which ultrasonic vibration is applied so as not to break through the adhesive sheet, and by picking up each semiconductor chip.
