Product Overview
Glacial acetic acid (CMOS grade) is a high-purity, ultra-low metal impurity solvent designed for critical applications in semiconductor manufacturing, microelectronics, and precision cleaning processes. With a minimum purity of 99.7%, this reagent ensures consistent performance in sensitive environments where trace contaminants can compromise results. Its anhydrous nature eliminates water interference, making it ideal for etching, photoresist stripping, and surface preparation in advanced fabrication workflows. The CMOS-grade specification guarantees compliance with stringent industry standards, reducing particulate and ionic contamination risks. Packaged in high-density polyethylene (HDPE) bottles, it maintains stability and prevents leaching, ensuring long-term reliability. This product is compatible with most standard lab glassware and automated dispensing systems, offering seamless integration into existing workflows. Its low volatility and controlled evaporation rate enhance process repeatability, while the absence of stabilizers or additives preserves the integrity of delicate substrates. Whether used in research labs or production facilities, this glacial acetic acid delivers the precision and purity required for high-yield, high-performance applications.
FAQs
1. What is the difference between CMOS-grade and reagent-grade acetic acid?
CMOS-grade acetic acid undergoes additional purification to remove metal ions and particulate contaminants below 10 ppb, whereas reagent-grade may contain higher impurity levels suitable for general lab use but not semiconductor applications.
2. Can this product be used for photoresist development?
Yes, its ultra-low metal content and high purity make it suitable for photoresist stripping and development processes in microfabrication without leaving residual contaminants.
3. How should this be stored to maintain its purity?
Store in a cool, dry place away from direct sunlight and oxidizing agents. Keep the bottle tightly sealed to prevent moisture absorption and contamination from ambient air.
4. Is this acetic acid compatible with stainless steel equipment?
While short-term contact is generally safe, prolonged exposure may cause corrosion. Use PTFE-lined or glass containers for long-term storage or processing to avoid metal leaching.
5. What is the typical shelf life of unopened CMOS-grade acetic acid?
When stored under recommended conditions, the product retains its specifications for at least 24 months from the date of manufacture, as indicated on the label.
