Latest Patents

One of her latest patents is titled "Epoxy-siloxanes based electrically conductive adhesives for semiconductor assembly and process for use thereof." This invention is directed towards enhancing conductive adhesives for solder-free interconnections in microelectronic assembly processes, such as chip carrier-to-substrate attachment. The adhesives are characterized by low tensile modulus, low resistivity, high adhesion strength, and durability under reliability stress conditions, including thermal shock and temperature/humidity exposure. The formulation includes a homogeneous solution of a siloxane containing epoxide, a curing agent, a curing catalyst, and an organic polymeric or oligomeric additive. Additionally, a conductive filler, preferably Ag coated with Pd or Au, is incorporated into the solution.

Another significant patent involves the use of conductive adhesive to form temporary electrical connections for temporary chip attach applications. This invention outlines a structure and method for converting a standard ceramic carrier into a temporary chip attach carrier. The process includes applying a secondary layer with holes on a substrate, filling these holes with conductive adhesive, and curing the adhesive before placing a chip with C4 solder bumps onto the layer. This innovative approach allows for the re-use of the secondary layer after the chip is separated.
