Abstract
The semiconductor device si formed by forming a first metal film over a first main surface of a semiconductor wafer having a first thinkness, performing back grinding to a second main surface of the semiconductor wafer thereby making a second thickness thinner than the first thickness and forming an insulation film pattern having a first insulation film and containing an annular insulation film pattern along the periphery of a second main surface of the semiconductor wafer over the second main surface along the periphery thereof. The second main surface of the semiconductor wafer is bonded to a pressure sensitive adhesive sheet thereby holding the device semiconductor wafer by way of the pressure sensitive adhesive sheet to a dicing frame in a state where the insulation film pattern is present.
