Microelectronic package electrostatic discharge (ESD) protection
Embodiments may relate to a microelectronic package comprising: a die and a package substrate coupled to the die with a first interconnect on a first face. The package substrate comprises: a second interconnect and a third interconnect on a second face opposite to the first face; a conductive signal path between the first interconnect and the second interconnect; a conductive ground path between the second interconnect and the third interconnect; and an electrostatic discharge (ESD) protection material coupled to the conductive ground path. The ESD protection material comprises a first electrically-conductive carbon allotrope having a first functional group, a second electrically-conductive carbon allotrope having a second functional group, and an electrically-conductive polymer chemically bonded to the first functional group and the second functional group permitting an electrical signal to pass between the first and second electrically-conductive carbon allotropes.
Methods for Making Functionalized Fluorinated Monomers, Fluorinated Monomers, and Compositions for Making the Same
A method of making a functionalized fluorinated monomer for use in making oligomers and polymers that can be used to improve surface properties of polymer-derived systems, such as coatings. The method of making a functionalized fluorinated monomer includes reacting at least one fluorinated nucleophilic reactant, such as a fluorinated alcohol, with at least one compound containing at least one epoxide group. Other methods include reaction of a fluorinated alcohol with a cyclic carboxylic anhydride. In another embodiment, a method includes reacting a fluorinated mesylate, tosylate or triflate with an amine, alkoxide or phenoxide. In other embodiments, the method includes reacting a fluorinated alcohol with an alkyl halide, or reacting a fluorinated alkyl halide with an amine.
