Product Overview
HCL 36% CMOS grade is a high-purity hydrochloric acid solution specifically formulated for critical semiconductor and microelectronics applications. This lab-grade acid undergoes rigorous purification to eliminate trace metal contaminants, ensuring minimal interference in sensitive processes. With a precise 36% concentration, it delivers consistent etching performance and reliable reactivity for CMOS fabrication workflows. The solution is stabilized to prevent degradation during storage, maintaining its efficacy over extended periods. Its low particulate content and controlled impurity profile make it ideal for advanced laboratory settings where precision and reproducibility are paramount. The acid is packaged in high-density polyethylene containers to prevent contamination and ensure safe handling. Whether used in photoresist stripping, surface cleaning, or selective material removal, this CMOS-grade HCL provides the purity and performance required for high-tech research and development environments.
FAQs
1. What is the typical shelf life of HCL 36% CMOS grade?
The product maintains its specified purity for 12-18 months when stored in its original sealed container at room temperature, away from direct sunlight and moisture.
2. Can this acid be used for general lab cleaning purposes?
While technically possible, this CMOS-grade HCL is specifically optimized for semiconductor applications and may be cost-prohibitive for routine cleaning tasks where lower purity grades would suffice.
3. What safety precautions should be taken when handling this chemical?
Always use in a well-ventilated fume hood with proper PPE including acid-resistant gloves, goggles, and lab coat. Neutralize spills immediately with sodium bicarbonate solution.
4. How does this compare to reagent-grade HCL?
CMOS grade has significantly lower metal ion content (typically <1 ppb for most metals) compared to reagent grade, which may contain up to 100 ppm of various impurities.
5. What container material is recommended for long-term storage?
The original HDPE container is optimal, but PTFE or PFA bottles can be used for smaller aliquots to prevent potential leaching of contaminants from other plastic types.
