Abstract: Various embodiments disclose a molding compound comprising a resin, a filler, and a carbon nano-tube dispersion and methods of forming a package using the molding compound is disclosed. The carbon non-tube dispersion has a number of carbon nano-tubes with surfaces that are chemically modified by a functional group to chemically bridge the surfaces of the carbon nano-tubes and the resin, improving adhesion between the carbon nano-tubes and the resin and reducing agglomeration between various ones of the carbon nano-tubes. The carbon nano-tube dispersion achieves a low average agglomeration size in the molding compound thereby providing desirable electro-mechanical properties and laser marking compatibility. A shallow laser mark may be formed in a mold cap with a maximum depth of less than about 10 microns. Other apparatuses and methods are disclosed.
