Patents by Inventor Wen-Chia Ou

Wen-Chia Ou 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).

  • Publication number: 20250072295
    Abstract: A method of fabricating a semiconductor device includes the following steps. A plurality of doped regions are formed in a substrate. A first dielectric layer is formed on the substrate. A plurality of first contacts and second contacts are formed in the first dielectric layer to be connected to the plurality of doped regions. A memory element is formed on the first dielectric layer. The memory element is electrically connected to the second contact. A second dielectric layer is formed on the first dielectric layer. The second dielectric layer surrounds the memory element. A conductive line is formed in the second dielectric layer. A top surface of the conductive line is at a same level as a top surface of the memory element, and the conductive line is electrically connected to the plurality of first contacts.
