Manufacturing method of device chip |
| abstract |
A manufacturing method of a device chip includes a die bonding resin providing step of supplying a die bonding resin in a liquid state to a back surface side of a wafer with device chips formed on a front surface thereof and solidifying the die bonding resin, a water-soluble resin providing step of covering the die bonding resin with a water-soluble resin, a laser processing step of applying a laser beam from the back surface side of the wafer to remove the die bonding resin and the water-soluble resin, an etching step of etching an exposed portion on the back surface side of the wafer to divide the wafer, and a water-soluble resin removing step of supplying water on the back surface side of the wafer to remove the water-soluble resin. |
