Abstract:
The present invention relates to a dicing die bonding film employed in a semiconductor packaging process, and a semiconductor device using the same. The dicing die bonding film is configured such that a ratio X/Y of adhesive power X between the wafer and the adhesive layer of the die bonding portion to tacky power Y between the die bonding portion and the tacky layer of the dicing portion is 0.15 to 1, and the adhesive layer of the die bonding portion has a storage modulus of 100 to 1000 MPa at a normal temperature. The dicing die bonding film according to the present invention reduces burr generation in dicing process, and thereby preparing a semiconductor device having excellent reliability without inferiority caused by bad connection reliability due to the burr covering a bonding pad.
