BASE RESIN FOR PHOTORESIST USING ULTRA-VIOLET RAY FORFABRICATION OF SEMICONDUCTOR DEVICE, ITS MANUFACTURINGMETHOD AND PHOTORESIST USING ULTRA-VIOLET RAY COMPRISING THE BASE RESIN |
摘要 |
PURPOSE: A structural resin for deep UV exposing photoresist composition and its preparation method are provided to use the resin to accomplish the exposure process by using deep UV as light source in the photolithographic process in the semiconductor production. CONSTITUTION: The structural resin comprises t-butoxycarbonyl oxystyrene (TBS) chain extended resin represented by the following formula 1 (R1 and R2 are hydrogen or alkyl group having C1-C5 including methyl or ethyl group; R5 is isopropyl group; m is natural number of 100-1,000,000 and n is natural number of 1-100). The resin is prepared by polymerizing TBS with inifer containing disulfide to synthesize TBS oligomer having TBS repeating units by deep UV as a light source in the lithographic process. The resin is prepared by extending chains of TBS oligomer to 4-thiol-alpha,alpha'-alkylbenzyl-4-thiolphenyl ester as a connector molecules. |
