    Abstract: PURPOSE: A process for forming a resist pattern using exposure radiation having a wavelength below 180 nm, and a resist composition suited therefor are provided. CONSTITUTION: A resist composition comprises: (A) a polymer comprising recurring units having an alicyclic hydrocarbon backbone to which a carboxylate moiety capable of generating carboxylic acid when decomposed under acidic conditions is attached through a C1-C20 alkylene spacer; (B) a photoacid generator; and (C) an organic solvent which is sensitive to high-energy radiation, and has excellent sensitivity and resolution at a wavelength below 180nm, and good plasma etching resistance. Because these features of the inventive resist composition enable its use particularly as a resist at the exposure wavelength of a F2 excimer laser, a finely defined pattern can easily be formed, making the resist ideal as a micropatterning material in VLSI fabrication.

    Abstract: KrF엑시머레이저가 조사되면 산을 발생하고, 상기 산에 의해 반응하는 화학증폭형 레지스트를 사용하여 반도체 기판상에 레지스트막을 형성한다. 마스크를 사용하여 KrF 엑시머레이저를 조사하면 레지스트막의 노광부 표면에서 산이 발생하고, 이 산에 의해 노광부 표면은 친수성으로 변화한다. 레지스트막의 표면에 수증기를 공급하면, 노광부에서 표면으로부터 깊은 부위까지 물이 확산한다. 상대습도 95%의 공기중에서 메틸트리에톡시시란 증기를 레지스트막 표면으로 내뿜으면 노광부 표면에 막두께가 큰 산화막이 선택적으로 형성된다.
