Patents by Inventor Chao-Kai Wu

Chao-Kai Wu 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: 11978664
    Abstract: A method includes forming a first conductive feature over a semiconductor substrate, forming an ILD layer over the first conductive feature, patterning the ILD layer to form a trench, and forming a conductive layer over the patterned ILD layer to fill the trench. The method further includes polishing the conductive layer to form a via contact configured to interconnect the first conductive feature with a second conductive feature, where polishing the conductive layer exposes a top surface of the ILD layer, polishing the exposed top surface of the ILD layer, such that a top portion of the via contact protrudes from the exposed top surface of the ILD layer, and forming the second conductive feature over the via contact, such that the top portion of the via contact extends into the second conductive feature.

  • Patent number: 11968817
    Abstract: A semiconductor device includes a fin structure. A source/drain region is formed on the fin structure. A first gate structure is disposed over the fin structure. A source/drain contact is disposed over the source/drain region. The source/drain contact has a protruding segment that protrudes at least partially over the first gate structure. The source/drain contact electrically couples together the source/drain region and the first gate structure.

  • Patent number: 11961886
    Abstract: Semiconductor structures and methods for manufacturing the same are provided. The semiconductor structure includes a substrate and nanostructures suspended over the substrate. The semiconductor structure also includes a gate structure wrapping around the nanostructures and a source/drain structure attached to the nanostructures. The semiconductor structure also includes a contact vertically over the source/drain structure and a first conductive structure vertically over the gate structure. The semiconductor structure also includes a second conductive structure in contact with a top surface of the first conductive structure and a top surface of the contact and including an extending portion laterally sandwiched between the first conductive structure and the contact.

  • Publication number: 20240008169
    Abstract: An electronic device is provided in this disclosure. The electronic device includes a display panel, a transmission line, a universal motherboard, and an optional panel power management module. The display panel is a first type display panel or a second type display panel. The transmission line is a first transmission line or a second transmission line. The universal motherboard is connected to the first type display panel through the first transmission line, or connected to the second type display panel through the second transmission line. When the display panel is the first type display panel, the panel power management module is connected to the universal motherboard and the first type display panel through the first transmission line, so that the panel power management module provides power management required for the first type display panel according to the universal motherboard.
