    摘要: A semiconductor device structure, along with methods of forming such, are described. The structure includes an interconnect structure disposed over a substrate, a first conductive feature disposed in the interconnect structure, a dielectric layer disposed on the interconnect structure, and a second conductive feature having a top portion and a bottom portion. The top portion is disposed over the dielectric layer, and the bottom portion is disposed through the dielectric layer. The structure further includes an adhesion layer disposed over the dielectric layer and the second conductive feature. The adhesion layer includes a first portion disposed on a top of the second conductive feature and a second portion disposed over the dielectric layer, the first portion has a thickness, and the second portion has a width substantially greater than the thickness.
