The compound (CAS No. 220155-95-3) is a specialized monomer primarily used in the formulation of chemically amplified photoresists (CARs) for semiconductor manufacturing. Its properties include:

• Reactivity: Designed to polymerize efficiently during photoresist formulation and contribute to controlled cross-linking or solubility changes under exposure.
• Compatibility: Highly compatible with acid generators (PAGs) and solvents used in ArF (193 nm) and DUV lithography resists.
• Thermal and Photochemical Stability: Stable under typical photoresist processing conditions but reactive under photogenerated acid catalysis, enabling fine pattern formation.
• Solubility: Soluble in common photoresist solvents such as propylene glycol monomethyl ether acetate (PGMEA), allowing homogeneous resist solutions.

Applications

The primary applications of CAS No. 220155-95-3 are in advanced photolithography processes:

1. ArF Photoresists (193 nm DUV Lithography)
   • Utilized in photoresists for the fabrication of semiconductor devices at feature sizes below 45 nm.
   • Functions as a monomer component that undergoes polymerization or cross-linking upon exposure to photogenerated acid.
2. DUV Lithography
   • Supports deep ultraviolet (DUV) patterning, enabling high-resolution features required in logic and memory device fabrication.
   • Works in conjunction with chemically amplified resist systems to improve sensitivity and resolution.
3. Photoacid Generator (PAG) Compatibility
   • Often incorporated with PAGs, which release acid upon exposure to light, initiating deprotection or crosslinking reactions in the resist polymer.
