Ammonium hydroxide (29%) from India for semiconductor manufacturing
Ideal for semiconductor wafer cleaning! High-purity ammonia water.
In the semiconductor manufacturing industry, the contamination of foreign substances and metal ions significantly affects product quality due to the fine processing of wafers. The cleaning process requires thorough removal of these impurities to maintain high purity levels. Inadequate cleaning can lead to reduced yield and degradation of device performance. Our Electronic Grade ammonia water (29%) from India employs an ultrapure water process through RO + DM treatment, achieving impurity removal at ppm to ppb levels. It supports high-quality cleaning in semiconductor manufacturing. 【Application Scenarios】 - Semiconductor wafer cleaning - Electronic component manufacturing - Cleanroom environments 【Benefits of Implementation】 - Improved yield due to high cleaning power - Mitigation of the impact of metal impurities on devices - Stable use in cleanroom environments
