  • Patent number: 8053894
    Abstract: Apparatus for forming a semiconductor structure comprising a first layer on top of a substrate wherein the first layer defines conductive regions such as copper interconnect lines and non-conductive regions such as dielectric materials. The conductive regions are covered by a second layer of a material different than the first layer such as for example nickel and then the structure is heat treated such that the interconnect lines and second metal, such as a copper interconnect line and a nickel second layer, interact with each other to form an alloy layer. The alloy layer has superior qualities for adhering to both the copper interconnect lines and a subsequently deposited dielectric material.

  • Patent number: 7354847
    Abstract: A process for trimming a photoresist layer during the fabrication of a gate electrode in a MOSFET is described. A bilayer stack with a top photoresist layer on a thicker organic underlayer is patternwise exposed with 193 nm or 157 nm radiation to form a feature having a width w1 in the top layer. A pattern transfer through the underlayer is performed with an anisotropic etch based on H2/N2 and SO2 chemistry. The feature formed in the bilayer stack is trimmed by 10 nm or more to a width w2 by a HBr/O2/Cl2 plasma etch. The pattern transfer through an underlying gate layer is performed with a third etch based on HBr/O2/Cl2 chemistry. The underlayer is stripped by an O2 ashing with no damage to the gate electrode. Excellent profile control of the gate electrode is achieved and a larger (w1?w2) is possible than in prior art methods.
