  • Contact features of semiconductor device and method of forming same
    Patent number: 12272600
    Abstract: A method includes forming a dielectric layer over an epitaxial source/drain region. An opening is formed in the dielectric layer. The opening exposes a portion of the epitaxial source/drain region. A barrier layer is formed on a sidewall and a bottom of the opening. An oxidation process is performing on the sidewall and the bottom of the opening. The oxidation process transforms a portion of the barrier layer into an oxidized barrier layer and transforms a portion of the dielectric layer adjacent to the oxidized barrier layer into a liner layer. The oxidized barrier layer is removed. The opening is filled with a conductive material in a bottom-up manner. The conductive material is in physical contact with the liner layer.

  • SEMICONDUCTOR DEVICE AND METHOD FOR FORMING THE SAME
    Publication number: 20250096155
    Abstract: A method for forming a semiconductor device is provided. The method includes forming a device layer over a device substrate and forming a front-side interconnect structure over the device layer. The method also includes forming a bevel oxide over an edge portion of the device substrate, an edge portion of the device layer, and an edge portion of the front-side interconnect structure. The method further includes forming an oxide layer over the device layer, the front-side interconnect structure, and the bevel oxide, polishing the bevel oxide and the oxide layer until a top surface of the bevel oxide is substantially level with a top surface of the oxide layer, and attaching a carrier substrate to the bevel oxide and the oxide layer.
