Abstract: The processing of radiation patternable organometallic coatings is shown to be improved through the appropriate selection of post processing conditions between coating and development of the pattern. In particular, a coated wafer can be subjected to process delays to allow aging of the coating at various process points, in particular following irradiation. Process delays can be combined and interspersed with heating steps. The atmosphere above the coated wafer at various process steps can be adjusted to obtain desired improvements in the development of the pattern. Reactive gases can be beneficial with respect to improvement of coating properties.

Abstract: The present invention provides a modular handguard for a firearm which allows a portion of the length of the handguard to be quickly and easily added or removed. The improved modular handguard of the present invention has a base which attaches to the barrel nut of the firearm. An extension slidably mates with the base such that the longitudinal bores of the base and the extension are generally aligned. A latch removably connects the base and the extension.
