  • Publication number: 20180039172
    Abstract: Stabilized precursor solutions can be used to form radiation inorganic coating materials. The precursor solutions generally comprise metal suboxide cations, peroxide-based ligands and polyatomic anions. Design of the precursor solutions can be performed to achieve a high level of stability of the precursor solutions. The resulting coating materials can be designed for patterning with a selected radiation, such as ultraviolet light, x-ray radiation or electron beam radiation. The radiation patterned coating material can have a high contrast with respect to material properties, such that development of a latent image can be successful to form lines with very low line-width roughness and adjacent structures with a very small pitch.

  • Publication number: 20170261850
    Abstract: High etch contrast materials provide the basis for using pre-patterned template structure with a template hardmask having periodic holes and filler within the holes that provides the basis for rapidly obtaining high resolution patterns guided by the template and high etch contrast resist. Methods are described for performing the radiation lithography, e.g., EUV radiation lithography, using the pre-patterned templates. Also, methods are described for forming the templates. The materials for forming the templates are described.

  • Publication number: 20160216606
    Abstract: Organometallic solutions have been found to provide high resolution radiation based patterning using thin coatings. The patterning can involve irradiation of the coated surface with a selected pattern and developing the pattern with a developing agent to form the developed image. The patternable coatings may be susceptible to positive-tone patterning or negative-tone patterning based on the use of an organic developing agent or an aqueous acid or base developing agent. The radiation sensitive coatings can comprise a metal oxo/hydroxo network with organic ligands. A precursor solution can comprise an organic liquid and metal polynuclear oxo-hydroxo cations with organic ligands having metal carbon bonds and/or metal carboxylate bonds.

  • Patent number: 9281207
    Abstract: Solution processible hardmasks are described that can be formed from aqueous precursor solutions comprising polyoxometal clusters and anions, such as polyatomic anions. The solution processible metal oxide layers are generally placed under relatively thin etch resist layers to provide desired etch contrast with underlying substrates and/or antireflective properties. In some embodiments, the metal oxide hardmasks can be used along with an additional hardmask and/or antireflective layers. The metal oxide hardmasks can be etched with wet or dry etching. Desirable processing improvements can be obtained with the solution processible hardmasks.

  • Publication number: 20110275046
    Abstract: The present disclosure describes methods, systems, and techniques for evaluating content, such as audio and video content. The content is presented to a respondent for evaluation. Feedback is collected from the respondent using a feedback collection device that presents different kinds of reactions to the respondent for selection during presentation of the content. Feedback is collected using a collection server and stored in a collection database. The feedback can be analyzed and summarized in a report to a pollster. Beneficially, the described methods, systems, and techniques allow for real-time collection of multiple respondent reactions, which facilitates accurate, efficient, and quick evaluation of the content.

  • Publication number: 20050157288
    Abstract: Methods and apparatuses for mounting a pellicle to a reticle is provided. A multi-support point pellicle holder supports a pellicle, such as a fused silica pellicle, and a multi-support point holder supports the reticle, where each point on the respective frame provides a substantially equal-force. An adhesive is added to the pellicle, where upon attaching the reticle pellicle, the weight of the reticle causes the adhesive spots to form a wider bonding layer, adhering the pellicle to the reticle. The adhesive layer is cured and a sealant is added in the spaces between the adhesive spots.
