  • Patent number: 12276913
    Abstract: Organometallic precursors are described for the formation of high resolution lithography patterning coatings based on metal oxide hydroxide chemistry. The precursor compositions generally comprise ligands readily hydrolysable by water vapor or other OH source composition under modest conditions. The organometallic precursors generally comprise a radiation sensitive organo ligand to tin that can result in a coating that can be effective for high resolution patterning at relatively low radiation doses and is particularly useful for EUV patterning. The precursors compositions are readily processable under commercially suitable conditions. Solution phase processing with in situ hydrolysis or vapor based deposition can be used to form the coatings.

  • Publication number: 20250093773
    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.

  • Publication number: 20250085627
    Abstract: Organotin patterning compositions can incorporate Sn—F bonds to improve pattering performance. A precursor solution for a radiation patterning composition can comprise a blend of an organic solvent, an organotin composition represented by the formula RSnL3, and a compound capable of generating Sn—F bonds wherein R is a substituted or unsubstituted hydrocarbyl ligand with 1 to 31 carbon atoms and an Sn—C bond and L is a hydrolysable ligand. The fluoride source can be an ammonium fluoride. The patterning structure on a substrate surface has RSnFn moieties, generally within an oxo-hydroxo network.

  • Publication number: 20250074930
    Abstract: Organotin patterning compositions have radiation sensitive ligands with acetal functional groups. Precursor compositions are compositions comprising (OR4)(OR3)R2CR1SnL3, where the R groups are substituted or unsubstituted hydrocarbyl groups and L is a hydrolysable ligand. The precursors can be formed into coating that can be patterned with radiation, in particular EUV radiation. Coatings formed with blended precursors with hydrocarbyl-based ligands with some having acetal groups and others lacking acetal groups can be particularly effective for improving positive tone patterning.

Solutions of these clusters are suitable for forming radiation sensitive coatings that can be used to pattern nanometer scale structures. The radiation sensitive coatings are particularly suitable for EUV patterning.

  • Patent number: 12184240
    Abstract: Low noise amplifiers (LNAs) with low noise figure are provided. In certain embodiments, an LNA includes a single-ended LNA stage including an input for receiving a single-ended input signal from an antenna and an output for providing a single-ended amplified signal, a balun for converting the single-ended amplified signal to a differential signal, and a variable gain differential amplification stage for amplifying the differential signal from the balun. Implementing the LNA in this manner provides low noise figure, high gain, flexibility in controlling gain, and less sensitivity to ground/supply impedance.

  • Publication number: 20240427237
    Abstract: Precursor solutions for radiation patternable coatings are formed with an organic solvent and monoalkyl tin trialkoxides in which the water content of the solvent is adjusted to be within 10 percent of a selected value. Generally, the water content of the solvent is adjusted through water addition, although water removal can also be used. In some embodiments, the adjusted water content of the solvent can be from about 250 ppm by weight to about 10,000 ppm by weight. With the appropriate selection of ligands, the adjusted precursor solutions can be stable for at least about 42 days, and in some cases at least 8 months.

  • Publication number: 20240386255
    Abstract: The present invention provides a hardware-aware mixed-precision quantization method and system based on a greedy search. It comprises quantizing all layers in the neural network to the uniform bit-width, conducting training-aware quantization, and acquiring the trained model, baseline inference accuracy, and total bit operation counts. Each layer in the neural network undergoes post-training quantization with low precision individually, and the corresponding inference accuracy and total bit operation counts for each layer are recorded. Single-layer sensitivity is computed based on the baseline inference accuracy, total bit operation counts, and the inference accuracy and total bit operation counts of each layer and guides the current total bit operation counts until reaching the preset maximum bit operation counts. Meanwhile, quantized layers and precision are recorded, determining the mixed-precision quantization strategy.

  • Publication number: 20240376135
    Abstract: Patterning compositions are described based on organo tin dodecamers with hydrocarbyl ligands, oxo ligands, hydroxo ligands and carboxylato ligands. Alternative dodecamer embodiments have organo tin ligands in place of hydrocarbyl ligands. The organo tin ligands can be incorporated into the dodecamers from a monomer with the structure (RCC)3SnQ, where R is a hydrocarbyl group and Q is a alkyl tin moiety with a carbon bonded to the Sn atom of the monomer and with a Sn bonded as a replacement of a quaternary carbon atom with bonds to 4 carbon atoms. Some or all of the carboxylato and hydroxyl ligands can be replaced with fluoride ions. Good EUV patterning results are obtained with the dodecamer based patterning compositions.

  • Patent number: 12119496
    Abstract: Present invention is related to a composite modified layer attached on a current collector comprising a lithiophilic particle being covered or coated by a polymer layer. The composite modified layer further could be coated with an additional carbon layer or artificial protective film as several suitable embodiments presented in this invention. The lithiophilic particle, such as sliver nano-particle, will firstly form a lithium-silver alloys to reduce a thermodynamic instability during the growth of lithium nuclei. The sliver nano-particle is able to be attached securely on the current collector by the polymer with high adhesion ability. The fuel cell including the composite modified layer in the present invention has higher average Coulombic efficiency and higher capacity retention.

  • Publication number: 20240337926
    Abstract: Organometallic radiation resist compositions are described based on tin ions with alkyl ligands. Some of the compositions have branched alkyl ligands to provide for improved patterning contrast while maintaining a high degree of solution stability. Blends of compounds with distinct alkyl ligands can provide further improvement in the patterning. High resolution patterning with a half-pitch of no more than 25 nm can be achieved with a line width roughness of no more than about 4.5 nm. Synthesis techniques have been developed that allow for the formation of alkyl tin oxide hydroxide compositions with very low metal contamination.
