    摘要: A method for forming a nickel silicide layer on a MOS device with a low carbon content comprises providing a substrate within an ALD reactor and performing an ALD process cycle to form a nickel layer on the substrate, wherein the ALD process cycle comprises pulsing a nickel precursor into the reactor, purging the reactor after the nickel precursor, pulsing a mixture of hydrogen and silane into the reactor, and purging the reactor after the hydrogen and silane pulse. The ALD process cycle can be repeated until the nickel layer reaches a desired thickness. The silane used in the ALD process functions as a getterer for the advantageous carbon, resulting in a nickel layer that has a low carbon content. The nickel layer may then be annealed to form a nickel silicide layer with a low carbon content.

    摘要: A deliberately engineered placement and size constraint (molecular weight distribution) of photoacid generators, solubility switches, photoimageable species, and quenchers forms individual pixels within a photoresist. Upon irradiation, a self-contained reaction occurs within each of the individual pixels that were irradiated to pattern the photoresist. These pixels may take on a variety of forms including a polymer chain, a bulky cluster, a micelle, or a micelle formed of several polymer chains. Furthermore, these pixels may be designed to self-assemble onto the substrate on which the photoresist is applied.

    摘要: Multiple-layer films in integrated circuit processing may be formed by the phase segregation of a single composition formed above a semiconductor substrate. The composition is then induced to phase segregate into at least a first continuous phase and a second continuous phase. The composition may be formed of two or more components that phase segregate into different continuous layers. The composition may also be a single component that breaks down upon activation into two or more components that phase segregate into different continuous layers. Phase segregation may be used to form, for example, a sacrificial light absorbing material (SLAM) and a developer resistant skin, a dielectric layer and a hard mask, a photoresist and an anti-reflective coating (ARC), a stress buffer coating and a protective layer on a substrate package, and light interference layers.
