Semiconductor Reactive Emulsifier COPS-2

Features Of Semiconductor Reactive Emulsifier COPS-2

1. Reactive surfactant with covalent bonding capability to polymer backbones, ensuring permanent stabilization and zero leaching in semiconductor-grade dispersions.

2. Ultra-low ionic impurity profile (<10 ppm total metals), meeting stringent requirements for photolithography and wafer cleaning formulations.

3. Thermally stable up to 220°C, enabling compatibility with high-temperature emulsion polymerization and post-cure processing steps.

4. pH-stable across 3.0–10.5, maintaining emulsion integrity under acidic etchants and alkaline developers used in front-end-of-line (FEOL) processes.

5. Hydrolytically robust ester-acrylate functionality enables rapid UV/thermal initiation without catalysts or side-product generation.

Typical Applications Of Semiconductor Reactive Emulsifier COPS-2

1. Stabilizer for photoresist-compatible acrylic and styrene-acrylic latexes used in advanced planarization layers.

2. Functional emulsifier in conductive polymer dispersions for antistatic spin-on coatings on silicon wafers.

3. Reactive compatibilizer in hybrid organic-inorganic nanoparticle suspensions (e.g., SiO₂, TiO₂) for EUV lithography topcoats.

4. Surface-modifying agent for polymeric CMP (chemical mechanical polishing) slurries to reduce defect density and improve particle adhesion control.

5. Anchor molecule in water-based dielectric barrier films for low-k material deposition via spray-coating or inkjet printing.

Semiconductor Reactive Emulsifier COPS-2 – Frequently Asked Questions (FAQ)

Q1: What is the CAS Registry Number for COPS-2?

A: The CAS Registry Number for Semiconductor Reactive Emulsifier COPS-2 is 2855372-89-1.

Q2: What is the recommended dosage range in semiconductor emulsion formulations?

A: Typical usage is 1.0–4.0 wt% relative to monomer charge; optimal performance is achieved at 2.2–2.8 wt% for most acrylic latex systems targeting <5 nm residual surfactant extractables.

Q3: How does COPS-2 compare to conventional nonreactive emulsifiers (e.g., SDS, Triton X-405) in semiconductor applications?

A: Unlike conventional emulsifiers, COPS-2 covalently incorporates into the polymer matrix—eliminating post-film formation migration, reducing rinse water contamination by >99%, and enabling sub-10 nm defect control in cleanroom environments.

Q4: Is COPS-2 compliant with SEMI S2/S8 safety standards and IEC 60175 migration limits for microelectronics packaging?

A: Yes—COPS-2 meets SEMI S2 (health & safety) and SEMI S8 (environmental impact) guidelines; validated per IEC 60175 Annex B for ≤0.5 µg/cm² extractable organics after 72 h at 60°C in deionized water.

Q5: Can COPS-2 be used in immersion lithography topcoat formulations without compromising water contact angle or leaching?

A: Yes—COPS-2 has been qualified in 193i topcoats at 0.8–1.5 wt%; it maintains water contact angle stability (>85°) and shows no detectable leaching (LOD <0.02 ppm) in immersion fluid after 1000-s exposure testing.
