Abstract:
A resist composition comprising(A) a basic compound of the following general formula (1) or (2): ##STR38##whereinR.sup.1, R.sup.2, R.sup.3, R.sup.7, and R.sup.8 are each independently normal, branched or cyclic alkylene groups having up to 20 carbon atoms,R.sup.4, R.sup.5, R.sup.6, R.sup.9, and R.sup.10 are each independently hydrogen, alkyl groups having 1 to 20 carbon atoms or amino groups, or R.sup.4 and R.sup.5, R.sup.5 and R.sup.6, R.sup.4 and R.sup.6, or R.sup.4, R.sup.5, and R.sup.6, and R.sup.9 and R.sup.10, in each case taken together, may also independently form a ring, andletters k, m and n are integers of 0 to 20,with the proviso that hydrogen is excluded from R.sup.4, R.sup.5, R.sup.6, R.sup.9, and R.sup.10 when k, m or n is equal to 0,(B) an organic solvent,(C) a base resin having an acidic functional group protected with an acid labile group, which is substantially alkali insoluble, but becomes alkali soluble when the acid labile group is eliminated, and(D) a photoacid generator.
