Abstract:
1. A method of reducing a likelihood that a die pad will be delaminated from a die in an integrated circuit die package for a structure design during an attachment of a heat sink member to the die pad using solder, wherein the heat sink member comprises metal, the method comprising: evaluating a sample structure of the structure design to determine whether a volume of last solidification for the solder is centrally located with respect to the die pad and is located at or near an interface of the solder and the die pad; and if the last solidification volume is centrally located and is located at or near the interface of the solder and the die pad, and if the die pad is delaminated from the die, modifying the structure design so that less metal of the heat sink member is centrally located than before the modifying.
