  • Publication number: 20110165516
    Abstract: A radiation-sensitive composition containing 1 to 80% by weight of a solid component and 20 to 99% by weight of a solvent. The solid component contains a compound B which has (a) a structure derived from a polyphenol compound A by introducing an acid-dissociating group to at least one phenolic hydroxyl group of the polyphenol compound A which is synthesized by a condensation between a di- to tetrafunctional aromatic ketone or aromatic aldehyde each having 5 to 36 carbon atoms with a compound having 1 to 3 phenolic hydroxyl groups and 6 to 15 carbon atoms, and (b) a molecular weight of 400 to 2000. The composition containing the compound B is useful as an acid-amplified, non-polymeric resist material, because it is highly sensitive to radiation such as KrF excimer lasers, extreme ultraviolet rays, electron beams, and X-rays, and provides resist patterns with a high resolution, high heat resistance, and high etching resistance.

  • Publication number: 20110159252
    Abstract: An orthogonal process for photolithographic patterning organic structures is disclosed. The disclosed process utilizes fluorinated solvents or supercritical CO2 as the solvent so that the performance of the organic conductors and semiconductors would not be adversely affected by other aggressive solvent. One disclosed method may also utilize a fluorinated photoresist together with the HFE solvent, but other fluorinated solvents can be used. In one embodiment, the fluorinated photoresist is a resorcinarene, but various fluorinated polymer photoresists and fluorinated molecular glass photoresists can be used as well. For example, a copolymer perfluorodecyl methacrylate (FDMA) and 2-nitrobenzyl methacrylate (NBMA) is a suitable orthogonal fluorinated photoresist for use with fluorinated solvents and supercritical carbon dioxide in a photolithography process.

  • Publication number: 20080206103
    Abstract: Methods for the preparation of a stable, self-assembled monolayer on the silicon surface or metallic coating of a microcantilever are disclosed. The methods produce a microcantilever suitable as a chemical sensor. In a microcantilever produced using one version of the method, a metallic coating is disposed on a side of the microcantilever, a bridging atom is bonded to the metallic coating, a first spacer group is bonded to the bridging atom, a second spacer group is bonded to the bridging atom, and a chemical recognition agent is bonded to the first spacer group. In another version of the method, a silicon surface of a microcantilever is hydrogen terminated, and a calixarene chemical recognition agent is carbon linked to the silicon surface using photochemical hydrosilylation. Among other things, the calixarene may be bonded to a crown ether for ion detection or bonded to a area for the recognition of explosives by hydrogen bonding to nitro groups.
