Latest Patents

Qing Zhang's latest patents include groundbreaking technologies such as a method for forming through substrate vias (TSVs). This method involves etching a via opening into the backside of a semiconductor substrate, which exposes a surface of a metal landing structure. A conductive layer is then deposited over the backside of the substrate and the sidewalls of the via opening. The process continues with the application of a polymer material that fills the via opening, followed by the development of the polymer to leave the opening filled with undeveloped material. The final step involves removing the conductive layer to create a planar backside surface of the semiconductor substrate. Another notable patent involves integrating a copper plating process in a TSV on a CMOS wafer, which enhances the interconnect capabilities of semiconductor devices.
