Latest Patents
Among his latest patents, Hung-Ju Chien has developed innovative semiconductor devices featuring post passivation interconnections and a buffer layer. This patent describes an integrated circuit that includes a passivation layer made of a non-oxide material, which is formed over the circuit that already has a first plurality of contact pads. A buffer layer, preferably a silicon oxide layer, is then created over the passivation layer, with a thickness significantly smaller than that of the passivation layer. A post passivation metal layer is subsequently deposited over the buffer layer, allowing for the formation of a second plurality of contact pads as part of a new connection pattern.
Another notable patent involves a method for reducing defects in the post passivation interconnect process. This method also utilizes a passivation layer of a non-oxide material, followed by the formation of a buffer layer and a post passivation metal layer. The connection pattern is then established in the post passivation metal layer, enhancing the reliability of integrated circuits.
