Top surface imaging process by selective chemisorption of diphenyl siloxane derivatives. |
초록 |
A new top surface imaging process has been developed in which a silicon-containing compound is adsorbed selectively on a patternwise exposed non-chemically amplified resist film. This approach offers a higher resolution because of the anisotropic pattern transfer of a thin imaging resist film containing silicon into the underlying polymer film. Upon irradiation in the deep UV, the polymer containing diazoketo groups become hydrophilic by the formation of carboxylic groups. An amine-functionalized diphenylsiloxane oligomer was chemisorbed using EDC/NHS coupling chemistry over the UV light-exposed regions of a diazoketo-functionalized photoresist surface. The chemisorbed diphenylsiloxane oligomer acts as the etch barrier during the subsequent O2-RIE process to generate patterns. In this system, we could avoid the problems of chemically amplified resists system and take the advantages of top surface imaging. |
