Ultrasonic Cleaning Chemicals Introduction
One of the largest challenges faced in the semiconductor manufacturing industry is the surface contamination of silicon wafers. Most commonly, silicon wafers become contaminated simply from exposure to the air, which contains a high degree of organic particle contaminants. These contaminants strongly bond to the silicon wafer surface due to a strong electrostatic force, creating a lot of headache for those in the semiconductor manufacturing industry.
In order to function properly, silicon wafers must be completely free of any contaminants. Removing these contaminants is not the simplest of tasks, however, as silicon wafers are very fragile. For this reason, semiconductor manufacturing businesses must adhere to a carefully formulated cleaning plan that ensures the wafer surfaces are returned to a clean state while maintaining minimal risk of damage.

Ultrasonic Cleaning Chemicals instructions
1) put pure water into cleaning tank till three-quarter, then, add agent in 3% concentration, add water till working level, last, heat the bath solution till working temperature.
2)need to change bath solution completely after degreasing certain amount silicon slice.
3) reduce exposed time in air to avoid oxidation.
4)working temperature 50-65 degree, disposal time: 2-5minutes.
