Patents by Inventor Chia-Tung HSU

Chia-Tung HSU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11978703
    Abstract: A semiconductor structure includes a conductive line, a pad layer, and a barrier layer. The conductive line is embedded in a multi-level interconnect structure. The pad layer is over the conductive line. The barrier layer is between the conductive line and the pad layer. The pad layer is electrically connected to the conductive line through the barrier layer, and the barrier layer includes a first poly-crystalline layer and a second poly-crystalline layer. A boundary is between the first poly-crystalline layer and the second poly-crystalline layer.
    Type: Grant
    Filed: November 17, 2022
    Date of Patent: May 7, 2024

  • Patent number: 11908800
    Abstract: A semiconductor structure includes a multi-level interconnect structure, a passivation layer, a barrier layer, and a pad layer. The passivation layer is above the multi-level interconnect structure. The barrier layer lines an inner sidewall of the passivation layer, a top surface of the passivation layer and a top surface of a conductive line of the multi-level interconnect structure. The barrier layer includes a first layer, a second layer, a third layer, and a fourth layer. The first layer is in a nano-crystalline phase. The second layer is above the first layer and in an amorphous phase. The third layer is above the second layer and in a polycrystalline phase. The fourth layer is above the third layer and in a nano-crystalline phase. The pad layer is above the barrier layer.
