Abstract:
A semiconductor device manufacturing method comprising:forming stud bumps electrically connected to elements on a main surface of a wafer on which the elements are formed, forming grooves with depths which do not reach the back surface of the wafer in the wafer on the main surface side thereof along dicing lines or chip dividing lines of the wafer, coating a stud bump forming surface side of the wafer with a seal member, performing a back side grinding process for the wafer to make the wafer thin, and at the same time, divide the wafer into individual chips, picking up one of the chips which are discretely divided by said performing the back side grinding process, and heating to melt the stud bumps of the picked-up chip to bond and mount the chip to and on a base board, and at the same time, melting the seal member to seal a gap between the picked-up chip and the base board.
