Monitoring Recirculated baths using WetSpec200

Specialized chemical mixtures used in semiconductor processing are necessary for the surface preparation of wafers. As little as 1% error in the dilution ratio can degrade yield in a sensitive process, both for acids for organic solvents that contain water as a component required for the removal of etch residuals….
