Abstract:
A semiconductor device is provided. The semiconductor device can have a substrate including dielectric material. A plurality of narrow interconnect openings can be formed within said dielectric material. In addition, a plurality of wide interconnect openings can be formed within said dielectric material. The semiconductor device can include a first metal filling the narrow interconnect openings to form an interconnect structure and conformally covering a surface of the wide interconnect openings formed in the dielectric material, and a second metal formed over the first metal and encapsulated by the first metal to form another interconnect structure within the wide interconnect openings.

Claim (Index 15):
The method of  claim 10 , wherein forming the interconnect opening within the dielectric material comprises:\n forming a hard mask stack over the dielectric material; performing a first etching process to etch the hard mask stack to form a hard mask pattern; coating a spin on carbon (SOC) hard mask layer over the patterned hard mask stack and patterning the SOC layer; performing a second etching process to etch down into the dielectric material by using the patterned SOC layer as a mask; removing the SOC layer; and performing a third etching process to etch down into the dielectric material by using the patterned hard mask stack as a mask to complete the formation of the interconnect opening having a trench opening, a via opening or a dual damascene opening.
