Claim:
1. A method for manufacturing a semiconductor device, the method comprising: bonding a first substrate to a first side of a second substrate; placing a first thermal interface material on the second substrate to a thickness of between about 5 μm and about 500 μm, wherein the placing the first thermal interface material places the first thermal interface material on the first side; and dispensing underfill material between the first substrate and the second substrate, the dispensing occurring after the placing the first thermal interface material on the second substrate, wherein during the dispensing the underfill material the first thermal interface material is part of a structure with a first exposed surface facing away from the first side, the first exposed surface being located a first distance away from the first side and wherein the first substrate has a second surface facing away from the first side, the second surface being located a second distance away from the first side, the second distance being greater than the first distance, wherein after the dispensing the underfill material the underfill material has a third surface facing away from the second substrate that is in contact with both the first thermal interface material and a sidewall of the first substrate perpendicular to the second substrate, the third surface being closer to second substrate than the second surface.
