A method of fabricating a copper interconnect on a substrate is disclosed in which the interconnect and substrate are subjected to a low temperature anneal subsequent to polarization of the interconnect and prior to deposition of an overlying dielectric layer. The low temperature anneal inhibits the formation of hillocks in the copper material during subsequent high temperature deposition of the dielectric layer. Hillocks can protrude through passivation layer, thus causing shorts within the connections of the semiconductor devices formed on the substrate. In one example, the interconnect and substrate are annealed at a temperature of about 200 ° C. for a period of about 180 seconds in a forming gas environment comprising hydrogen (5 parts per hundred) and nitrogen (95 parts per hundred).

A method of fabricating notching free metal interconnection lines by utilizing aluminum nitride (AlN) as an anti-reflection coating. First, field oxide regions are formed on a semiconductor silicon wafer. Then, electrical element structures such as transistor, capacitor and resistor are formed on the predetermined area. Next, a barrier layer, a metal layer and an anti-reflection layer are successively deposited overlaying the entire silicon wafer surface. Next, the photoresist pattern is formed by the conventional lithography technique. By using photoresist pattern as an etching protection mask, the barrier layer, metal layer and anti-reflection layer are also patterned to form metal interconnection lines. Thereafter, the photoresist is stripped by oxygen plasma and sulfuric acid.
