  • Publication number: 20090321847
    Abstract: The present invention relates to complementary metal-oxide-semiconductor (CMOS) devices having gapped dual stressors with dielectric gap fillers. Specifically, each CMOS device of the present invention includes at least one n-channel field effect transistor (n-FET) and at least one p-channel field effect transistor (p-FET). A tensilely stressed dielectric layer overlays the n-FET, and a compressively stressed dielectric layer overlays the p-FET. A gap is located between the tensilely and compressively stressed dielectric layers and is filled with a dielectric filler material. In one specific embodiment of the present invention, both the tensilely and compressively stressed dielectric layers are covered by a layer of the dielectric filler material, which is essentially free of stress. In an alternatively embodiment of the present invention, the dielectric filler material is only present in the gap between the tensilely and compressively stressed dielectric layers.

  • Patent number: 7563558
    Abstract: The present invention provides polymers that are useful in negative resist compositions. Polymers of the present invention comprise (1) a first monomer having a polar functional group; (2) a second monomer; and optionally, (3) a third monomer that imparts at least one characteristic selected from crosslinkable functionality, etch resistance, and solubility modulation. The first monomer provides an acid catalyzed polarity switch upon elimination of the polar functional group, whereas, the second monomer provides aqueous dissolution. The polymers of the present invention may be incorporated into negative resist compositions, which may also include photoacid generators, crosslinking agents, basic compounds, solvents, dissolution accelerators, photobase generators, latent basic compounds, surfactants, adhesion promoters, and anti-foaming agents.

  • Publication number: 20090093114
    Abstract: A method of forming a dual-damascene wire. The method includes forming a via opening in a dielectric layer, filling the via opening with a polymeric formation including at least about 6% by weight of solids of thermal acid generator; heating the polymeric underlayer to a temperature greater than room temperature but less than about 180° C.; lithographically forming a trench in the dielectric layer and filling the via opening and the trench with an electrical conductor, a top surface of the electrical conductor substantially co-planer with the top surface of the second dielectric capping layer.

  • Publication number: 20080292825
    Abstract: The present invention provides a process for preparing a melt-processed organic-inorganic hybrid material including the steps of maintaining a solid organic-inorganic hybrid material at a temperature above the melting point but below the decomposition temperature of the organic-inorganic hybrid material for a period of time sufficient to form a uniform melt and thereafter, cooling the uniform melt to an ambient temperature under conditions sufficient to produce the melt-processed organic-inorganic hybrid material.
