Thin Film Control & Solution related to OLED
Precision deposition for OLED, where nanometer-level accuracy defines display quality.
About the webinar
OLED manufacturing demands some of the tightest thickness control in the industry. This webinar dives into the measurement science and solutions we offer to make precise, repeatable OLED deposition possible.
Starting with the fundamentals of Quartz Crystal Microbalance (QCM) technology, piezoelectricity, frequency-to-thickness conversion, and the Lu & Lewis equation, you'll build a clear understanding of how real-time film thickness monitoring works. The session then explores the key factors that directly impact measurement quality in OLED processes: crystal cut types (AT, BC, SC) and their temperature stability trade-offs, Z-Ratio accuracy for different organic materials, and crystal life and ACT value monitoring to predict sensor replacement before it affects your process.
A highlight is our Mode Lock technology, which eliminates the "mode hopping" noise problem that plagues conventional oscillators during long OLED deposition runs, extending crystal life and delivering cleaner rate signals with 0.005 Hz sensitivity. The webinar also compares our Cygnus2 and IMM200 controllers with cross-validation data proving equivalent performance.
