Electronic Grade IPA (IPA UP/SEMI G5)

Description

1. Product Overview

Electronic Grade IPA (Isopropyl Alcohol), SEMI G5 / UP grade, is an ultra-high-purity solvent engineered for critical contamination control in semiconductor and microelectronics manufacturing. Primarily used in wafer rinsing, precision cleaning, and drying processes, it delivers sub-10 ppb total metal impurity levels and minimal particle counts. Strategically vital as global chipmakers push toward sub-5nm nodes, this product directly enhances device yield, reduces defect density, and ensures process stability—making it an indispensable consumable in advanced fabs and display fabs worldwide.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Isopropyl Alcohol (C₃H₈O), ≥99.999% purity (anhydrous)

• Purity Grade: SEMI G5 / UP (Ultra-Pure) – metals <10 ppt (parts per trillion) per element; anions <1 ppb

• Particle Count: ≤10 particles/mL (>0.1 µm)

• Water Content: ≤100 ppm (Karl Fischer)

• Physical Characteristics: Clear, colorless liquid; characteristic alcohol odor; density 0.785 g/mL @20°C; evaporation residue ≤1 ppm

• Packaging Options:

  • 4L HDPE bottle (nitrogen-purged, double-bagged, cleanroom class 10)

  • 20L stainless steel drum (inner electropolished)

  • 200L stainless steel drum

  • 1000L IBC (stainless steel or fluorinated liner)

  • Bulk ISO tank for direct fab delivery

• Shelf Life: 24 months from manufacture when stored in sealed, inert containers under nitrogen atmosphere at 15–25°C

3. Core Industrial Applications

• Semiconductor Wafer Fabs: Final rinse after wet etching or CMP to eliminate metal ions and organic residues before lithography—reduces killer defects by up to 40% vs. standard IPA.

• Flat Panel Display (FPD) & OLED Manufacturing: Precision cleaning of glass substrates and mask plates; G5 purity prevents pixel defects and improves luminous efficiency.

• Hard Disk Drive (HDD) & MEMS Production: Ultrasonic cleaning of heads, sliders, and micro-structures; low residue ensures stiction-free operation and longer device life.

• Pharmaceutical & Medical Electronics (High-Reliability Devices): Used in cleanroom assembly of implantable electronics where ionic contamination must be zero.

• Performance Advantage: Lower surface tension than water enables faster drying without water marks; evaporates completely, leaving no trace—unlike lower-grade IPA or acetone.

4. Competitive Advantages

• Quality Consistency: Lot-to-lot statistical process control (SPC) with COA on every shipment; 100% tested via ICP-MS and particle counter; guaranteed <5 ppb per critical metal (Fe, Na, Al, Cu, Cr).

• Supply Reliability: Dual-source manufacturing (Asia + Europe) with buffer stock in regional hubs (US, EU, SEA) to mitigate geopolitical or logistics disruptions.

• Logistics Capability: Cleanroom-certified filling lines; temperature-controlled shipping; real-time tracking via IoT-enabled containers.

• Price Competitiveness: Tier-1 quality at 8–12% lower landed cost vs. incumbent G5 suppliers due to automated filtration and scale.

• Sustainability: Returnable stainless steel drum program reduces container waste by 70%; recycling option for spent IPA (closed-loop solvent recovery system available with major clients).

• Technical Support: Full validation package (metals, particles, FTIR, GC-MS) + on-site compatibility testing for your existing filtration and dispensing equipment.
