Chemical restrictions are reshaping semiconductor and microelectronics industries.

New chemical restrictions are rapidly reshaping the semiconductor and microelectronics industries, elevating expectations for chemical transparency, emissions control, and material accountability. As fabrication processes grow more complex and materials are used at increasingly small scales, manufacturers face mounting pressure to understand chemical risk proactively—across processes, products, and supply chains.

Regulators are moving from just reacting to chemical rules to requiring companies to show they understand and manage chemicals better, with new rules about PFAS  bans, “forever chemicals,” and supply-chain transparency.

In the United States, the EPA’s TSCA Section 8(a)(7) PFAS reporting rule requires manufacturers and importers to disclose detailed information on PFAS identity, uses, volumes, byproducts, worker exposure, and environmental releases—even for historical or low-concentration uses. PFAS are also being added to the Toxics Release Inventory (TRI), increasing public and stakeholder scrutiny of emissions, waste streams, and pollution prevention practices. At both the state and global levels, laws requiring disclosure of PFAS products and proposed EU-wide restrictions under REACH create extra challenges for semiconductor supply chains that depend on specialty chemicals, coatings, process aids, and fluorinated materials.

RJ Lee Group: Proactive Product Stewardship and Regulatory Readiness

RJ Lee Group helps semiconductor and microelectronics companies translate regulatory complexity into actionable, defensible strategies. Our services are designed to support proactive product stewardship, regulatory readiness, and business continuity—without disrupting innovation or manufacturing performance.

Our experts support clients through:

• Chemical risk assessments and regulatory gap analyses aligned with TSCA, TRI, and state PFAS requirements.
• Product and process chemical characterization to identify regulated, emerging, or unknown substances.
• Supply-chain transparency initiatives, including material verification and impurity screening.
• Data generation and documentation to support regulatory reporting, customer disclosures, and ESG claims.

This integrated approach allows manufacturers to anticipate regulatory changes, reduce compliance uncertainty, and engage confidently with regulators and stakeholders.

Advanced Analytical Services for Ultra-Trace Chemical Insight

At the heart of RJ Lee Group’s offering is advanced chemical characterization and contamination analysis, purpose-built for high-precision manufacturing environments.

Using real-time analytical technologies—including Proton-Transfer-Reaction Time-of-Flight Mass Spectrometry (PTR-TOF-MS) and Aerosol Ionization and Mobility Spectrometry (AIMS)—RJ Lee Group can:

• Detect, identify, and quantify ultra-trace volatile and semi-volatile compounds at parts-per-trillion (ppt) levels.
• Characterize PFAS precursors, breakdown products, and next-generation process chemicals.
• Rapidly screen emissions, cleanroom environments, tools, materials, and process streams.
• Identify unknown contaminants that may not appear on standard target analyte lists.

PTR-TOF-MS enables continuous, high-resolution monitoring of VOCs and SVOCs with minimal sample preparation—making it ideal for early-stage risk identification and real-time process insight.

These capabilities support RJ Lee Group’s broader services in:

• Root cause analysis of contamination events
• Process optimization and emissions reduction
• Evaluation of alternative chemistries and materials
• Pre-compliance and pre-market risk screening

Turning Regulatory Pressure into Strategic Advantage

In an era of accelerating chemical restrictions, proactive insight is a competitive advantage. Relying solely on historical data or legacy testing approaches exposes companies to unexpected changes in reporting obligations, customer requirements, or supply-chain disruptions.

By integrating regulatory expertise, advanced analytical testing, and risk-based decision support, RJ Lee Group enables semiconductor and microelectronics manufacturers to:

• Stay ahead of evolving PFAS and emerging contaminant regulations.
• Reduce uncertainty in product and process decisions.
• Protect market access and customer trust.
• Strengthen sustainability and ESG initiatives.
• Safeguard innovation while demonstrating environmental responsibility.

RJ Lee Group helps you move from reactive compliance to informed control—supporting resilient operations, regulatory confidence, and long-term performance in a rapidly changing chemical landscape.
