  • Patent number: 11996298
    Abstract: A method for processing an integrated circuit includes forming a plurality of transistors.

  • Publication number: 20240145470
    Abstract: A method for processing an integrated circuit includes forming first and second gate all around transistors. The method forms a dipole oxide in the first gate all around transistor without forming the dipole oxide in the second gate all around transistor. This is accomplished by entirely removing an interfacial dielectric layer and a dipole-inducing layer from semiconductor nanosheets of the second gate all around transistor before redepositing the interfacial dielectric layer on the semiconductor nanosheets of the second gate all around transistor.
