Summary: | PROBLEM TO BE SOLVED: To provide a thermosetting sheet for hollow sealing of a semiconductor device, excellent in sealing properties, flux resistance, flux cleaning solution resistance, resistance against sealing material ingress pressure, and reliability, and a semiconductor device hollow-sealed using the same.SOLUTION: A thermosetting sheet for hollow sealing of a semiconductor device includes a thermosetting resin layer and a support layer having one side on which the thermosetting resin layer is formed. The support layer is selected from among glass, or aluminum, copper, stainless steel and an alloy of the metals. The thickness of the thermosetting resin layer is 3-30 μm, the thickness of the support layer is 5-50 μm, and the flow amount after the thermosetting resin layer before thermosetting thereof is pressed at 160°C and 2 MPa for 18 seconds is 100-1,500 μm.SELECTED DRAWING: Figure 4
