Sulfonyldiazomethane compounds containing a long-chain alkyl- or alkoxy-naphthyl group are novel and useful as photoacid generators. Chemical amplification type resist compositions comprising the same are suited for microfabrication because of many advantages including improved resolution, improved focus latitude, and minimized line width variation or shape degradation even on long-term PED.
