Isopropyl Alcohol (IPA) – Semiconductor Grade

Semiconductor Grade IPA is used for rinsing, drying, and water displacement during wafer cleaning and surface preparation. It must meet ultra-high purity standards to prevent contamination.

Key Details:
• Chemical Formula: C₃H₈O
• Molecular Weight: 60.10 g/mol
• CAS Number: 67-63-0
• Appearance: Clear, colorless liquid
• Purity: ≥99.999% (5N Semiconductor Grade)
• Boiling Point: 82.5°C

Applications:
• Wafer drying and cleaning in semiconductor fabrication
• Removal of moisture from wafer surfaces before lithography
• Final cleaning step to minimize particle contamination

Safety Note: Highly flammable; keep away from ignition sources. Use in well-ventilated environments.
