Latest Patents

One of Dubois' latest patents is titled "Surface modification by polymer anchoring on porous substrates." This invention discloses a method for mechanically anchoring polymers on the surface of a porous substrate by trapping polymer chains within the pores of the substrate under capillary forces. The method allows for surface modification of the porous substrate by anchoring one end of the polymer chains within the pores while allowing one or more other ends to dangle from the surface. This unique approach modifies the surface of a material without the need for chemical reactions or precursor-substrate interactions.

Another significant patent is "Semiconductor interconnect structure having enhanced performance and reliability." This invention outlines an interconnect structure and method for fabricating it, which enhances performance and reliability by minimizing oxygen intrusion into a seed layer and an electroplated copper layer. The process involves forming at least one opening in a dielectric layer, creating a sacrificial oxidation layer to minimize oxygen intrusion, and subsequently forming a barrier metal layer, seed layer, and electroplated copper layer. The result is a planarized surface that improves the overall reliability of semiconductor interconnects.
