Case Study: Advanced Packaging, Purification and testing for Ultra-Pure Hazardous Chemicals

When a semiconductor industry customer needed to enhance the usability, traceability, and safety of a hazardous chemical used in precision manufacturing, they turned to Trace Zero for a custom solution. The bulk-supplied material, while functional, presented four key challenges:

• Potential foreign debris and suspended particulate.

• A lack of detailed Certificate of Analysis (COA) data, including trace metals and physical characteristics

• Difficult handling due to bulk packaging.

• Inconsistent cleanliness and presentation of packaging in their cleanroom environment.

  
  

Beyond the Original COA: What Trace Zero Adds

Trace Zero began by filtering the chemical to remove foreign debris and turbidity, using application-specific purification or filtration options tailored to semiconductor purity expectations. Depending on the material and its use case, these may include:

• 10 µm to 1 µm pre-filtration for removal of gross particulates,

• Advanced purification steps to remove trace metals,

• Sub-micron filtration for fine particulate control,

• Ultrafiltration to 20 nm for critical-grade polishing and contaminant removal,

These staged options ensure the final material meets or exceeds semiconductor-level clarity and cleanliness, supporting high-precision manufacturing environments.

The product is then subjected to enhanced COA verification including:

• Trace Element Analysis (ICP-MS)

• Anion Analysis

• pH & Concentration Validation

• Moisture Content Measurement

• Turbidity Check & Visual Inspection

  
  

These extended tests are critical to semiconductor device performance, yield, and reliability.

Safer, Scalable Packaging

To improve usability and global logistics, Trace Zero down packed the filtered chemical into user manageable pails, making it:

• Easier and safer to handle

• Optimized for process integration

• Eligible for global shipping

  
  

Each unit is filled with precision, meeting a fill sensitivity tolerance of ±0.2 kg, ensuring accurate dosing for the end user and reducing the risk of process variability. This level of control supports consistency across batches and enhances operator confidence in single-use applications.

This packaging reduces accident risk, minimizes contamination or transpiration from repeated tote or drum access, and eliminates product waste from overuse or exposure. Each pail is custom labeled per the end user's requirements, ensuring clear traceability and regulatory compliance. Trace Zero is even able to provide labels translated to end user language requirements.

Process Controls that Meet Semiconductor Demands

Trace Zero doesn’t stop at packaging. Additional engineering control testing is performed to meet industry expectations, even when not explicitly required. These may include:

• Advanced ICP-MS Trace Metal Screening

• Moisture & Assay Testing with Stability Studies

• Shelf-Life Validation for Long-Term Reliability

• Method Specific Gage Repeatability & Reproducibility

  
  

These steps result in tight batch-to-batch consistency, early detection of quality deviations, and lower rework and waste rates, leading to:

• Reduced costs

• Improved device performance

• Supply chain assurance
