Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A semiconductor device, comprising:
a first source/drain contact extending out of a semiconductor substrate;
a gate electrode;
a dielectric layer disposed over the first source/drain contact and the gate electrode, having a first conductive structure over the first source/drain contact and a second conductive structure over the gate electrode, comprising oxygen, wherein a first oxygen percentage of a sidewall of the first conductive structure is equal to or greater than a second oxygen percentage of a top surface of the dielectric layer, wherein the second oxygen percentage is greater than zero;
a first conductive fill material disposed in the first conductive structure; and
a second conductive fill material disposed in the second conductive structure.
