Semiconductor Raw Material MS Reagent PGMEA

Features Of Semiconductor Raw Material MS Reagent PGMEA

1. Ultra-high purity (≥99.99% GC), rigorously tested for trace metal contaminants (Na, K, Fe, Cu < 10 ppt) to prevent device yield loss.

2. Low volatility and controlled evaporation rate ensure uniform photoresist film formation during spin-coating processes.

3. Excellent solvency for common positive-tone photoresists (e.g., novolac-based and chemically amplified resists) without inducing gelation or haze.

4. Stabilized formulation with proprietary inhibitor system minimizes peroxide formation during long-term storage.

5. Consistent lot-to-lot performance validated via in-line process monitoring across advanced lithography nodes (28 nm to 5 nm).

Typical Applications Of Semiconductor Raw Material MS Reagent PGMEA

1. Primary solvent in photolithography processes for semiconductor front-end-of-line (FEOL) and back-end-of-line (BEOL) patterning.

2. Carrier medium for photoresist dispersions used in immersion and extreme ultraviolet (EUV) lithography tools.

3. Cleaning agent for post-develop residue removal in wafer-level packaging and MEMS fabrication lines.

4. Formulation component in advanced anti-reflective coatings (ARCs) and bottom anti-reflective coatings (BARCs).

5. Process chemical in high-resolution mask writing and reticle cleaning applications requiring low particulate generation.

Semiconductor Raw Material MS Reagent PGMEA – Frequently Asked Questions (FAQ)

Q1: What is the CAS number for Semiconductor Raw Material MS Reagent PGMEA?

A: The CAS Registry Number is 108-65-6, corresponding to Propylene Glycol Monomethyl Ether Acetate (PGMEA) in its ultra-high-purity semiconductor grade form.

Q2: What is the typical recommended usage concentration when diluting PGMEA for photoresist formulation?

A: PGMEA is used undiluted as the primary solvent in most standard photoresist formulations; dilution is not recommended unless specified in the resist manufacturer’s technical data sheet, as it may compromise film uniformity and resolution.

Q3: How does MS Reagent PGMEA differ from commercial-grade PGMEA in terms of semiconductor suitability?

A: MS Reagent PGMEA undergoes additional sub-micron filtration (<0.02 µm), rigorous trace metal analysis (ICP-MS), and organic impurity profiling (GC-MS) — ensuring compliance with SEMI C36 and S23 standards, unlike general industrial-grade PGMEA which lacks such controls.

Q4: Is MS Reagent PGMEA compliant with REACH, RoHS, and US EPA TSCA regulations?

A: Yes — fully compliant with REACH SVHC-free status, RoHS Directive 2011/65/EU (exempted substance under Annex III), and listed on the US EPA TSCA Inventory; full regulatory documentation available upon request with batch-specific CoA.

Q5: Does PGMEA exhibit leaching or migration into underlying low-k dielectric layers during post-apply bake (PAB)?

A: No significant migration occurs under standard PAB conditions (90–130 °C, 60–90 sec); thermal gravimetric analysis (TGA) and FTIR cross-sectioning confirm complete solvent evaporation prior to soft-bake completion, minimizing interfacial contamination risks.
