A chemical amplification type resist composition contains as a photoacid generator a sulfonyldiazomethane compound of formula (1) wherein R is H or C
1-4
alkyl or alkoxy, G is SO
2
or CO, R
3
is C
1-10
alkyl or C
6-14
aryl, p is 1 or 2, q is 0 or 1, p+q=2, n is 0 or 1, m is 3 to 11, and k is 0 to 4. The composition is suited for microfabrication, especially by deep UV lithography because of many advantages including improved resolution and improved pattern profile after development.
