CONTACT FEATURES OF SEMICONDCUTOR DEVICES

Abstract:

A semiconductor device includes a conductive feature, a dielectric layer disposed over the conductive feature, and a contact feature extending through the dielectric layer. The contact feature has an upper portion and a lower portion. The upper portion is spaced apart from the dielectric layer with a spacer layer. The lower portion is electrically coupled to the conductive feature and in contact with the dielectric layer.
