Patents by Inventor Ming-Kai LO

Ming-Kai LO 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: 20240371867
    Abstract: An integrated circuit die includes a FinFET transistor. The FinFET transistor includes an anti-punch through region below a channel region. Undesirable dopants are removed from the anti-punch through region during formation of the source and drain regions. When source and drain recesses are formed, a layer of dielectric material is deposited in the recesses. An annealing process is then performed. Undesirable dopants diffuse from the anti-punch through region into the layer of dielectric material during the annealing process. The layer of dielectric material is then removed. The source and drain regions are then formed by depositing semiconductor material in the recesses.
    Type: Application
