Latest Patents

One of Zhou's most recent patents is titled "Pulse Reverse Electrodeposition for Metallization and Planarization of Semiconductor Substrates". This invention describes a novel method for electroplating a smooth layer of metal onto a microrough electrically conductive substrate. The method involves immersing both the substrate and a counterelectrode in an electroplating bath, followed by applying a modulated reversing electric current. This current consists of cathodic and anodic pulses, with specific duty cycles and ratios that optimize the plating process. Notably, the plating bath may be devoid of levelers and brighteners, indicating a more streamlined approach.

Another significant patent by Zhou is "Electrodeposition of Metals in Small Recesses Using Modulated Electric Fields". This invention details how a layer of metal can be electroplated onto a substrate with small recesses, where the transverse dimension does not exceed approximately 350 micrometers. Similar to the previous patent, it utilizes modulated reversing electric currents, emphasizing cathodic and anodic pulse duty cycles and frequency ranges. These methods offer improvements in the precision and efficiency of electroplating in challenging micro-scale applications.
