Abstract: A fuse for semiconductor devices in accordance with the present invention includes a substrate having a conductive path disposed on a surface thereof, a dielectric layer disposed on the substrate and a vertical fuse disposed perpendicularly to the surface through the dielectric layer and connecting to the conductive path, the vertical fuse forming a cavity having a liner material disposed along vertical surfaces of the cavity, the vertical surfaces being melted to blow the fuse. Methods for fabrication of the vertical fuse are also included.

Abstract: In integrated circuits having copper interconnect and low-k interlayer dielectrics, a problem of open circuits after heat treatment was discovered and solved by the use of a first liner layer of Ti, followed by a conformal liner layer of CVD TiN, followed in turn by a final liner layer of Ta or TaN, thus improving adhesion between the via and the underlying copper layer while reducing the increase in resistance caused by alloying between the Ti and the Copper to an acceptable amount.

Abstract: Disclosed is a method for depositing a metal layer on an interconnect structure for a semiconductor wafer. In the method, a metal conductor is covered by a capping layer and a dielectric layer. The dielectric layer is patterned so as to expose the capping layer. The capping layer is then sputter etched to remove the capping layer and expose the metal conductor. In the process of sputter etching, the capping layer is redeposited onto the sidewall of the pattern. Lastly, at least one layer is deposited into the pattern and covers the redeposited capping layer.
