  • Method and system for integrated circuit packaging
    Patent number: 7402270
    Abstract: According to one embodiment of the invention, a mold tool for packaging integrated circuits includes a first mold press die including a first non-planar surface and a second mold press die including a second non-planar surface. The first and second non-planar surfaces form the upper and lower surfaces of a mold cavity when the first and second mold press die are engaged. The mold tool also includes a bright TiN coating disposed on the first non-planar surface. The bright TiN coating operates to decrease residue on the first non-planar surface from a mold compound.
