Anti-Foaming Agents (ELECTRONIC GRADE)

Description

1. Product Overview

This Electronic Grade Anti-Foaming Agent is a high-purity, non-contaminating formulation engineered specifically to eliminate process foam in semiconductor, flat-panel display, and printed circuit board (PCB) manufacturing. Its primary industrial use is to prevent microbubble-induced defects in critical wet processes such as photoresist development, etching, and CMP slurry handling. The key value proposition is a 0.1µm filtration rating and ultra-low metal ion content, ensuring zero defect generation on sensitive wafers. Strategically, this product is essential for achieving sub-5nm node yields, directly reducing scrappage rates and increasing fab throughput—a non-negotible input for advanced foundries.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Non-ionic, silicone-free polyether dispersion (100% active, no hydrocarbon diluents)

• Purity Level: Electronic Grade (SEMI C46-0306 compliant); Metal ions < 1 ppb per element (Na, K, Fe, Cu, Zn)

• Physical Characteristics:

  • Form: Transparent low-viscosity liquid

  • Color: APHA ≤ 10

  • Particle Size: 100% < 0.1 µm (filtered)

  • Viscosity: 50–150 cP @ 25°C

  • Density: 1.01–1.05 g/cm³

• Packaging Options: 1L, 5L, 20L HDPE bottles (cleanroom double-bagged); 200L drums (Class 10 cleanroom filled); 1,000L IBCs

• Shelf Life: 18 months when stored in original sealed container at 5–30°C (non-humidity sensitive)

3. Core Industrial Applications

• Primary Industries: Semiconductor foundries, wafer-level packaging (WLP), advanced substrate manufacturing, LCD/OLED display fabs.

• Specific Operational Use Cases:

  • Photoresist development bath foam suppression (reduces pinhole defects by 99.7%).

  • CMP slurry transport and dispensing (prevents settling-induced foaming, ensuring uniform particle distribution).

  • High-aspect-ratio etching (eliminates bubble masking effects in deep silicon trenches).

• Performance vs. Alternatives: Unlike silicone-based agents (which cause residue defects) or hydrocarbon defoamers (incompatible with photochemicals), this polyether formulation rinses completely without post-process contamination. It achieves foam knockdown in < 30 seconds vs. 120 seconds for standard grades, directly increasing wet station throughput by up to 12%.

4. Competitive Advantages

• Quality Consistency: ISO 9001:2025 + IATF 16949 certified; each batch includes ICP-MS metal scan and particle count certificate (COA provided with shipment).

• Supply Reliability: Dedicated electronic-grade production line (no crossover with industrial grades). Safety stock held in three regional hubs (Asia, EU, NA) ensuring 5-day lead time.

• Logistics Capability: ESD-safe, climate-controlled cleanroom packaging; full UN-certified for air, sea, and ground transport.

• Price Competitiveness: Direct-from-manufacturer pricing—30% lower than incumbent specialty chemical distributors for equivalent 20MT volumes.

• Sustainability: 100% VOC-free; REACH and TSCA compliant; recyclable HDPE packaging with take-back program available.

• Technical Support: On-call field application engineers (previous 10+ years at Tier 1 fabs) for process integration support.
