Latest Patents

Wang holds a patent for a novel method aimed at preventing the formation of voids in metal interconnects. This method is particularly relevant during the thermal anneal process, which is essential for reducing electrical resistance in interconnects. The patent describes a technique where metal interconnects are fabricated between metal lines on a wafer. During the thermal anneal process, the wafer is positioned in a spaced-apart relationship to a wafer heater. This configuration enhances stability and uniformity in heating, thereby reducing the presence of particles and ensuring a uniform flow of heated air or gas against the wafer's backside. As a result, this method effectively eliminates or significantly reduces the formation of voids in the interconnects.
