Abstract: In a semiconductor structure, a first conductive feature is formed in a trench by PVD and a glue layer is then deposited on the first conductive feature in the trench before CVD deposition of a second conductive feature there-over. The first conductive feature acts as a protection layer to keep silicide from being damaged by later deposition of metal or a precursor by CVD. The glue layer extends along the extent of the sidewall to enhance the adhesion of the second conductive features to the surrounding dielectric layer.
