  • Patent number: 8017568
    Abstract: Supercritical carbon dioxide may be utilized to remove resistant residues such as those residues left when etching dielectrics in fluorine-based plasma gases. The supercritical carbon dioxide may include an oxidizer in one embodiment.
    Type: Grant

  • Patent number: 7361455
    Abstract: Anti-reflective materials such as bottom anti-reflective coatings (BARC's) and sacrificial light absorbing materials (SLAM) may be made more effective at preventing coherent light or electron beam reflection from a substrate by including in the anti-reflective material an additive to alter the radiation beam path of the reflected light or electrons. The radiation beam path altering additive may be a reflective material or a refractive material. The inclusion of such a radiation beam bath altering additive may reduce line width roughness and increase critical dimension (CD) control of interconnect lines and vias.

  • Patent number: 7241707
    Abstract: 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.

  • Patent number: 7241560
    Abstract: A basic developer/quencher solution formulated to include at least one supercritical fluid or liquid solvent and a base may be used to quench a photo-generated acid within a photoresist as well as develop the photoresist. The supercritical fluid or liquid solvent may be carbon dioxide and the base may be quaternary ammonium salt that has side groups that increase the solubility of the quaternary ammonium salt in carbon dioxide.

  • Publication number: 20040265734
    Abstract: A system, method, and software to form photoresist resin which has a more uniform distribution of polymers are disclosed. In one embodiment, the method includes introducing a first monomer into a reaction vessel; introducing a second monomer into the reaction vessel; and introducing an initiator into the reaction vessel to cause a polymerization of the first and second monomers, wherein the introducing the first and second monomers into the reaction vessel is performed in a manner that a concentration ratio of the first and second monomers is a function of a predetermined inverse relationship to a reactivity ratio of the first and second monomers. In another embodiment, the method includes introducing an initiator into the reaction vessel to cause a living or pseudo-living polymerization of the first and second monomers.

  • Publication number: 20040079388
    Abstract: Supercritical carbon dioxide may be utilized to remove fluorine-based etch residues such as those residues left when etching dielectrics in fluorine-based plasma gases. The supercritical carbon dioxide may have dissolved in it various reagents and fluorocarbon materials that, together, cause the residue to swell and to be exposed for reactions with the reagents, the supercritical carbon dioxide, and the fluorocarbons. As a result, relatively hard to penetrate fluorine-based residues may be entered and removed using aggressive chemistries.

  • Patent number: 6409316
    Abstract: A thermal ink jet printhead having an upper substrate and a lower substrate in which one surface thereof has an array of heating elements and addressing electrodes formed thereon. The lower substrate has an insulative layer deposited on the surface thereof and over the heating elements and addressing electrodes and patterned to form recesses therethrough to expose the heating elements and terminal ends of the addressing electrodes. The upper and lower substrates are bonded together to form a thermal ink jet printhead having droplet emitting nozzles defined by the upper substrate, the insulative layer on the lower substrate, and the heating elements in the lower substrate. At least one of the upper substrate and the insulative layer comprises a crosslinked polymer formed by crosslinking a precursor polymer which is a phenolic novolac resin having glycidyl ether functional groups on the monomer repeat units thereof.
