Latest Patents

Liu Wuping's latest patents focus on the structure and method for fabricating a bond pad structure. This invention provides an improved bond pad structure that includes a top wiring layer and a top dielectric (IMD) layer over a semiconductor structure. The process involves forming a buffer dielectric layer over the top wiring layer and the top dielectric layer. A buffer opening is created in the buffer dielectric layer, exposing a portion of the top wiring layer. A barrier layer is then formed over the buffer dielectric layer and the top wiring layer in the buffer opening. Following this, a conductive buffer layer is applied over the barrier layer, which is subsequently planarized to create a buffer pad in the buffer opening. A passivation layer is formed over the buffer pad and the buffer dielectric layer, with a bond pad opening created in the passivation layer over the buffer pad. Finally, a bond pad support layer and a bond pad layer are formed and patterned to establish a bond pad and bond pad support.
