Popis: Supercritical carbon dioxide (scCO2) solubility characteristics of various polyphenols and their derivatives were investigated for the sake of resist materials for scCO2 development. Some 3 nuclei-polyphenols were fairly soluble in scCO2 at the condition of pressure: 15MPa, temperature: 38 °C. Among various subustituent groups, only carboxylic acid COOH structure was a strong dissolution-inhibition factor, but other polar groups, hydroxyl, carboxylic-acid ester structures, such as methyl, ethyl, ter-butyl esters, were not fatal dissolution-inhibition factors in the films for scCO2. It was presumed that existence of hydrogen bonding interaction in the film strongly affect the film dissolution in scCO2.
