Electronic Grade Ethyl Silicate | Semiconductor Manufacturing

Semiconductor Applications

Critical precursor for advanced chip production

CVD/ALD Processes

Electronic Grade TEOS is the industry-standard precursor for depositing high-quality silicon dioxide thin films in semiconductor manufacturing.

Chemical Vapor Deposition (CVD): Forms uniform SiO₂ layers for insulation and passivation
Atomic Layer Deposition (ALD): Enables ultra-thin, conformal oxide films with atomic-level precision
PECVD Applications: Plasma-enhanced processes for lower temperature deposition
Thermal CVD: High-quality oxide layers for gate dielectrics and interlayer dielectrics
Film Quality: Produces dense, low-defect SiO₂ with excellent electrical properties

Chip Fabrication

Critical for advanced semiconductor device manufacturing across all technology nodes.

Gate Dielectrics: Insulating layers in transistor structures
Interlayer Dielectrics (ILD): Isolation between metal interconnect layers
Passivation Layers: Protective coatings for chip surfaces
STI Fill: Shallow trench isolation for device separation
Advanced Nodes: Suitable for 7nm, 5nm, and emerging 3nm processes
3D NAND: Layer deposition in vertical memory structures

Quality Requirements

Electronic Grade TEOS must meet stringent semiconductor industry standards to prevent contamination and defects in critical chip manufacturing processes.

Ultra-High Purity (99.999%): Five-nines (5N) minimum purity prevents electrical performance degradation and ensures consistent film properties. Even trace impurities can cause device failure in advanced technology nodes.
Metal Impurities (<1 ppb each): Sub-parts-per-billion levels of alkali metals (Na, K), transition metals (Fe, Cr, Cu, Ni), and heavy metals (Pb, Zn) are critical. Metal contamination causes junction leakage, threshold voltage shifts, and reliability failures.
Particle Control (<5/mL): Rigorous 0.1μm filtration minimizes yield-killing defects. Particles create shorts, opens, and pattern defects in sub-micron features. Clean-room handling throughout production and packaging is essential.
Moisture Content (<10 ppm): Ultra-low water prevents hydrolysis, ensures stable vapor delivery, and maintains consistent deposition rates. Moisture control is critical for reproducible CVD/ALD processes.
Halides (<0.1 ppm Cl⁻): Chloride and other halogen contaminants cause corrosion and reliability issues in metal interconnects and can degrade oxide quality.
Clean Packaging: ISO Class 5 (Class 100) clean-room compatible containers with certified cleanliness. Electropolished stainless steel or fluoropolymer-lined vessels prevent contamination during storage and transfer.
Batch Consistency: Lot-to-lot variation must be minimized to ensure process repeatability. Statistical process control ensures every batch meets specifications.
Full Traceability: Certificate of Analysis (CoA) with ICP-MS metal analysis, particle count data, and purity verification. Chain-of-custody documentation for quality assurance and audit compliance.
Stability: Minimum 12-month shelf life under proper storage conditions (cool, dry, inert atmosphere). Stability testing ensures no degradation over time.
