Indian tungsten trioxide for semiconductor thin films
Supports thin film formation with high purity WO₃. Stable supply without reliance on China.
In the semiconductor industry, the quality of thin film materials is crucial for enhancing performance and reliability. In particular, the uniformity, adhesion, and heat resistance of thin films are important factors that influence device performance. Contamination by impurities and degradation of film quality can lead to reduced yield and shortened product lifespan. Our tungsten trioxide (WO₃) sourced from India is of high purity and China-free, contributing to the resolution of challenges in thin film formation with stable quality and supply systems. 【Usage Scenarios】 - Sputtering targets - Raw materials for CVD/ALD - Thin film formation in semiconductor manufacturing processes 【Benefits of Implementation】 - High-quality thin film formation with high purity WO₃ - Stable supply due to being China-free - Optimal material provision through particle size and grade adjustments
