KOSEN SEMI addresses critical procurement and cleaning equipment installation questions by providing transparent empirical data, customized engineering workflows, and pre-installation laboratory testing to eliminate operational risks for semiconductor fabrication facilities worldwide.
Every yield enhancement metric published in KOSEN SEMI case studies originates from empirical wafer fab production data collected over extended operational windows. Prior to equipment integration, baseline yield loss, surface defect density, and particle levels are documented across a minimum of 1,000 consecutive production wafers.
Post-installation performance is verified using automated optical inspection (AOI) systems and total reflection X-ray fluorescence (TXRF) spectroscopy. Surface particle counts are verified at 200 nm thresholds, with optimized evaluation down to 100 nm, ensuring metallic contamination levels stay strictly below <0.005 ppb. die-level parametric yield improvements are independently calculated and signed off by client fab engineering supervisors.
