Abstract
A method and device comprising an easily reworkable alpha particle barrier is provided. The easily reworkable alpha particle barrier is applied in the space between the surface of the chip and the surface of the substrate, and reduces soft error rate (SER). Further, the easily reworkable alpha particle barrier material is chosen from the group of an organic material, a hydrocarbon, more specifically a polyalphaolefin (PAO) oil, and a polymer or filled polymer; wherein the polyalphaolefin oil has a viscosity below 1000 cSt (at 100° C.). The easily reworkable alpha particle barrier material can be used with multichip modules (MCM's) allowing easy device rework of one or more dies without affecting other dies on the same substrate.
