Latest Patents

Yu-Hsiang Wang holds a patent for a method titled "Via anchor profile control." This invention focuses on improving the control of via anchor profiles in metals at a contact layer. The method involves slowing down the anchor etching process and introducing a passivation operation. By first passivating a metallic surface, etchants are prevented from dispersing along grain boundaries, which can distort the shape of the via anchor. An iterative scheme that includes multiple cycles of alternating passivation and etching operations can effectively control the formation of optimal via anchor profiles. When a desirable anchor shape is achieved, it maintains the structural integrity of the vias, thereby improving the reliability of the interconnect structure.
