Popis: The properties of a nanocomposite resist formed by the addition of ruthenium metal clusters, [Ru11H(CO)27]3−, to PMMA has been investigated. Depending on the amount added, the nanocomposite resist displayed a reduction in rate of dry etching of between 20% and 55%. The sensitivity of the resist was found to be 7 C/m2. Contrast was not affected. Gratings of 80 nm pitch have been fabricated.
