As microelectronics, semiconductors, and advanced materials continue to evolve, the demand for high-purity thin film deposition materials has never been greater.
Through our partnership with Strem Chemicals, J&K Scientific offers an extensive portfolio of CVD (Chemical Vapor Deposition) and ALD (Atomic Layer Deposition) precursors, along with specialized delivery equipment and related services, providing a complete solution for research, development and commercial-scale production.
High-Purity CVD & ALD Precursors
Our range of high-performance metal and organometallic precursors is designed to meet the stringent purity and performance requirements of the thin film industry.
- Over 500 precursors available
- 60+ different elements covered across the periodic table
- Purity levels from 99% to 99.9999% metals basis
These precursors support applications across:
- Semiconductors and microelectronics
- Optoelectronic devices
- Photovoltaics and MEMS manufacturing
- Protective and functional coatings
e.g. Deposition of high-κ dielectrics (HfO₂, Al₂O₃), conductive films (TiN, Ru), and barrier layers for interconnects.
CVD Bubblers: Engineered for Reliability
To ensure safe and precise delivery of volatile metal precursors, we provide a full line of electropolished stainless steel bubblers, available in both horizontal and vertical configurations.
| Specification | Details |
|---|---|
| Volume Range | 150 mL – 3000 mL |
| Temperature Rating | Standard diaphragm valve: 121°C (PCTFE stem tips) |
| High-Temperature Option | Bellows valve rated to 315°C |
| Compliance | DOT-approved designs available |
Each bubbler is electropolished and assembled under clean conditions to ensure contaminant-free operation and reliable long-term use in industrial and research environments.
ALD Cylinders: High-Purity & Customizable
We also offer a wide selection of ALD precursor cylinders in various materials and sizes, including standard, high-temperature and ultra-high purity models.
- 50 mL Swagelok® cylinders (ideal for R&D)
- High-purity and high-temperature cylinders for demanding processes
- Larger capacities available upon request
All cylinders are designed for safe transport and controlled precursor delivery, ensuring compatibility with modern ALD systems.
Comprehensive ALD/CVD Support Services
Beyond supplying chemicals and hardware, we provide end-to-end services that enhance safety, efficiency, and operational uptime for thin film laboratories and fabs.
- Filling and refilling of bubblers and cylinders
- Precision cleaning and leak testing
- Equipment reconditioning and quality validation
- Handling of custom containers and third-party equipment
With decades of experience in hazardous and moisture-sensitive materials, we ensure every cylinder and bubbler is cleaned, filled, and certified to meet global standards.
Enabling Advanced Thin Film Manufacturing
As part of the Ascensus Specialties Group, Strem Chemicals combines decades of expertise in high-purity metal-organic chemistry with J&K Scientific’s distribution and technical support network.
Together, we enable customers across academia, industry, and production to access reliable thin film deposition materials and services from gram-scale R&D to ton-scale industrial use.
