  • Patent number: 10627719
    Abstract: Methods are described for removing edge bead on a wafer associated with a resist coating comprising a metal containing resist compositions. The methods can comprise applying a first bead edge rinse solution along a wafer edge following spin coating of the wafer with the metal based resist composition, wherein the edge bead solution comprises an organic solvent and an additive comprising a carboxylic acid, an inorganic fluorinated acid, a tetraalkylammonium compound, or a mixture thereof. Alternatively or additionally, the methods can comprise applying a protective composition to the wafer prior to performing an edge bead rinse. The protective composition can be a sacrificial material or an anti-adhesion material and can be applied only to the wafer edge or across the entire wafer in the case of the protective composition. Corresponding apparatuses for processing the wafers using these methods are presented.

  • Publication number: 20200064733
    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.

  • Publication number: 20190391486
    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: 20190369489
    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: 20190308998
    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.

  • Publication number: 20190153001
    Abstract: Organotin clusters are described with the formula R3Sn3(O2CR?)5-x(OH)2+x(?3-O) with 0?x<2; R=branched or cycloalkyl with 1 to 31 carbon atoms; R??H or alkyl with 1 to 20 carbon atoms. Three carboxylato ligands are bridging, and two OH ligands are bridging. The remaining two carboxylato ligands are in non-bridging configurations, and the non-bridging carboxylato ligands are exchangeable in solution. 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.

  • Publication number: 20190137870
    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.

  • 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.
