1. Semiconductor Wafer Cleaning and Etching Solutions

Semiconductor facilities depend on ultra-high-purity fluorinated liquids for precision cleaning and selective etching throughout integrated circuit fabrication. Its consistent chemical properties, low surface tension, and minimal residue profile meet the technical demands of deep sub-micron device geometries and advanced logic node migration, supporting defect reduction and electrical yield improvement in wafer production lines.

Industry compliance standards

• SEMI C3 (Specification for Specialty Gases and Liquids Used in Semiconductor Processing)
• IEC 60749-30 (Cleanliness of semiconductor surfaces)
• ISO 14644 (Cleanroom and controlled environments certification)
• JEITA guidelines for microcontamination control

Typical usage ratio

• Ranges from 3% to 7% by volume in aqueous or solvent cleaning/etching baths; precise concentration depends on target materials (e.g., silicon, tungsten, copper) and required rate of removal or cleaning aggressiveness

Downstream process integration

• Added to wet bench tanks or ultrasonic cleaning/etching equipment immediately following photolithography, CMP (chemical mechanical planarization), or before dielectric layer deposition; bath composition tailored per wafer processing step

Final product types

• Etched silicon wafers for memory, logic, or sensor ICs
• Cleaned semiconductor substrates for display panels
• MEMS device wafers

2. Precision Cooling Dielectric for High-Performance Computing Electronics

Data center and high-frequency module manufacturers utilize fluorinated dielectric fluids as cooling media inside immersion systems and direct-chip cooling enclosures for FPGAs, GPUs, and 5G/AI server nodes. Its dielectric constant, chemical inertia, and non-flammability support reliable heat removal while preventing short circuits, crucial for stable server operation and component longevity.

Industry compliance standards

Typical usage ratio

• Immersion system fill ratios between 100% fluid volume and variable topping-off schedules based on evaporative losses; leak-safe systems operate at 95%-100% charge to ensure continuous flow and cooling

Downstream process integration

• Pumped and circulated within closed-loop immersion tanks or direct-to-chip cold plates, maintained at stable pressures and flow rates for live operation cooling cycles

Final product types

• Immersion-cooled servers for cloud and AI computing
• Base stations for 5G and edge computing
• Cooler modules for supercomputing arrays

3. Environmental Test Fluid for Connector and Device Hermeticity Verification

Electronic fluorinated liquid functions as an oxygen- and moisture-impervious immersion medium in leak testing, thermal shock, and environmental simulation for hermetic electronic packages and microelectronic connectors. Its low boiling point and high chemical stability outperform hydrocarbon-based alternatives in simulating demanding application extremes without creating corrosive byproducts.

Final product types

• Hermetically sealed semiconductor packages for automotive and aerospace
• High-reliability microelectronic connectors
• Critical sensors and relays validated for harsh environments

4. Optical Lens Manufacturing and Precision Cleaning

Optical and photonics companies inject specialty fluorinated liquids into the cleaning and rinsing stages of high-precision optical glass and lens element production. The excellent non-reactivity and ultra-low residue help achieve flawless lens surfaces, critical for camera modules, medical imaging optics, and high-power laser assembly, where trace oil or dust cannot be tolerated.

Final product types

• Multi-element camera module lenses for mobile and surveillance products
• Medical imaging endoscope lenses

5. Electronic Component Encapsulation and Moisture Barrier Formulation

Manufacturers of advanced chip-scale packages and electronic encapsulants integrate fluorinated liquid as a dispersed phase in low-k dielectric or moisture-resistant polymer matrices. Its role is to reduce dielectric constant and block water ingress during underfill, potting, and overmolding of sensitive microelectronic devices, key to reliability for automotive, aerospace, and telecommunications assemblies.
