America’s Purest Propylene

High Purity for High Precision

High-purity liquid propylene is essential in semiconductor manufacturing, especially in the chemical vapor deposition (CVD) processes. It also plays a critical role in plasma etching and cleaning applications. High-purity propylene minimizes contamination, ensuring the precision and reliability required for producing high-quality electronic components.

Applications include:

• Plasma Etching & Cleaning: The material undergoes chemical reactions that allow precise etching of the semiconductor layers to form the circuits. High-purity propylene is crucial for reducing impurities in the etching process, which can lead to defects in the final semiconductor products.
• Chemical Vapor Deposition (CVD): In advanced semiconductor processes, thin carbon films or carbon-based layers can be deposited on wafers to serve as hard masks during pattern transfer steps. High-purity propylene can be used as a precursor gas for depositing these films through CVD techniques, which require materials of extremely high purity to avoid contamination and ensure high-performance results.
• Photoresist Monomer Production: Photoresists are light-sensitive materials applied to semiconductor wafers to create intricate patterns that define the circuits on microchips. High-purity propylene ensures the reliability and precision needed for these sensitive processes.

Industrial-Grade vs. Semiconductor-Grade Propylene

Unlike its industrial counterpart, semiconductor-grade propylene must adhere to strict purity standards, as even minor impurities can compromise the performance of microchips and electronic components. Our propylene meets or exceeds these standards, providing a consistent, reliable product.

The Consequences of Impurities

Semiconductor manufacturing is sensitive to contamination. Impurities can lead to defects, causing entire batches of products to fail quality checks, resulting in costly delays and financial losses. Using high-purity propylene ensures fewer defects, improving yield rates and overall device performance.
