Semiconductor Raw Material Specialty Amine Series Monoisopropanolamine

Features Of Semiconductor Raw Material Specialty Amine Series Monoisopropanolamine

1. Ultra-high purity (≥99.95%) with stringent metal ion control (Na, K, Ca, Fe, Cu < 10 ppb) for semiconductor-grade process compatibility.

2. Low volatility and controlled vapor pressure ideal for cleanroom-compatible chemical delivery systems (CDS) and vapor-phase deposition precursors.

3. Exceptional hydrolytic stability and thermal robustness up to 180 °C, ensuring consistent performance in high-temperature wafer cleaning and etch-resist formulations.

4. Engineered low residual moisture (<50 ppm) and minimal aldehyde impurities (<1 ppm), reducing risk of particle generation or film defects.

5. Non-corrosive to stainless steel (316L) and fluoropolymer (PFA, ETFE) wetted materials, supporting long-term system integrity in ultrapure fluid handling.

Typical Applications Of Semiconductor Raw Material Specialty Amine Series Monoisopropanolamine

1. Advanced photoresist strippers and post-etch residue removers for 7 nm and sub-5 nm logic/foundry nodes.

2. Stabilizing ligand in metal-organic precursors for atomic layer deposition (ALD) of high-k dielectrics (e.g., HfO₂, ZrO₂).

3. Co-solvent and pH buffer in ultra-low surface tension CMP slurries for copper and low-k dielectric polishing.

4. Complexing agent in electroless plating baths for selective barrier layer formation (e.g., CoWP, NiB).

5. Functional additive in spin-on carbon hardmask (SOC) formulations to enhance etch selectivity and pattern fidelity.

Semiconductor Raw Material Specialty Amine Series Monoisopropanolamine – Frequently Asked Questions (FAQ)

Q1: What is the CAS Registry Number for this specialty monoethanolamine derivative?

A: The CAS number for Monoisopropanolamine (1-Amino-2-propanol) is 78-96-6. This grade is a purified semiconductor variant meeting SEMI specifications, not a generic commercial material.

Q2: What is the typical recommended dosage range in photoresist stripper formulations?

A: Dosage is formulation-dependent but typically ranges from 2–8 wt% in aqueous-organic blends; optimal concentration must be validated per resist type and process temperature to balance stripping rate vs. metal corrosion control.

Q3: How does this mono-isopropanolamine differ from standard monoethanolamine (MEA) in semiconductor applications?

A: The isopropyl group imparts lower water solubility, higher boiling point, and reduced hydrogen-bonding capacity versus MEA—enabling better selectivity in resist removal, improved thermal stability in ALD precursors, and lower volatility during vapor-phase delivery.

Q4: Is leaching or extractables testing data available for contact with PFA and quartz components?

A: Yes—certified extractables data per SEMI F57 is provided: total organic extractables < 0.5 ppm after 72-hr static exposure at 60 °C in PFA tubing and quartz vessels; no detectable fluorinated or siloxane leachates by GC-MS.
