Semiconductor Raw Material Specialty Amine Series Triisopropanolamine

Features Of Semiconductor Raw Material Specialty Amine Series Triisopropanolamine

1. Ultra-high purity (≥99.95%) with stringent metal ion control (Na, K, Ca, Fe, Cu & Ni < 10 ppb), meeting SEMI C12 and ISO 8503-1 Class 1 requirements for semiconductor-grade processing.

2. Low volatility and high thermal stability—retains structural integrity up to 180°C—enabling compatibility with high-temperature CMP slurry formulations and post-etch cleaning processes.

3. Triple hydroxyl functionality provides superior chelating capacity for transition metals and alkaline earth ions, minimizing surface contamination and micro-roughness on Si, SiO₂, and low-k dielectrics.

4. Non-volatile, non-corrosive amine structure eliminates residue formation and wafer edge bevel etching, supporting sub-7nm node lithography integrity.

5. Controlled amine basicity (pKb ≈ 4.2) enables precise pH buffering in aqueous slurries without aggressive hydrolysis of sensitive gate oxides or metal interconnects.

Typical Applications Of Semiconductor Raw Material Specialty Amine Series Triisopropanolamine

1. Chemical Mechanical Planarization (CMP) slurry additive for copper and barrier (Ta/TaN) polishing—enhances removal rate uniformity and reduces dishing/erosion.

2. pH stabilizer and complexing agent in post-CMP cleaning solutions for advanced logic and memory devices (DRAM, NAND Flash).

3. Co-formulant in photoresist strip and ash residue removal chemistries for EUV and DUV lithography processes.

4. Stabilizer for colloidal silica and ceria nanoparticles in next-generation abrasive-free polishing formulations.

5. Functional component in ultra-low-k (k < 2.5) dielectric repair and pore-sealing treatments during BEOL integration.

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

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

A: CAS No. 122-20-3 (Triisopropanolamine, ultra-high purity grade). Certificate of Analysis includes full traceability to raw material synthesis batch and purification history.

Q2: What is the typical dosage range in CMP slurries, and how does it affect removal rate?

A: Standard dosing is 0.05–0.3 wt% in final slurry. At 0.15 wt%, it increases copper RR by ~12% vs. baseline while reducing TaN RR by ≤3%, improving selectivity ratio (Cu/TaN) by >25% without increasing surface roughness (Ra < 0.12 nm).

Q3: How does this product differ from standard commercial triisopropanolamine (TIPA)?

A: Unlike commodity TIPA (purity ~95–98%, metal impurities >1 ppm), this grade undergoes multi-stage vacuum distillation, chelation filtration, and cleanroom-packaging under ISO Class 4 conditions—ensuring semiconductor-grade purity, particle count, and lot-to-lot consistency required for front-end-of-line (FEOL) applications.

Q4: Is there any risk of amine leaching or migration into silicon wafers during high-temperature processing?

A: No measurable migration occurs. Independent TOF-SIMS depth profiling (up to 500°C anneal, 30 min) shows zero detectable nitrogen signal beyond native oxide interface (<0.01 atomic %), confirming non-diffusive behavior and absence of volatile degradation byproducts (e.g., isopropanol, diisopropanolamine).

Q5: Does this material comply with JEDEC J-STD-020 moisture sensitivity and outgassing requirements for packaging materials?

A: Yes. Tested per ASTM E595: Total Mass Loss (TML) = 0.12%, Collected Volatile Condensable Materials (CVCM) = 0.03% — well below JEDEC limits (TML ≤ 1.0%, CVCM ≤ 0.10%). Certified for use in wafer-level packaging and bumping process environments.
