Summary
Technical specialist who designs and simulates the film structures of thin films with optical properties, and examines and evaluates optimal coating processes.
Description
Optical thin film design engineers design and simulate multilayer film structures for optical thin films such as anti-reflective coatings, high-reflective coatings, and bandpass filters using interference calculation software (TFCalc, FilmStar, etc.), and optimize film thickness and material selection. They analyze measurement results from spectrophotometers and ellipsometers, and adjust deposition processes (PVD, CVD, sputtering, etc.) and manufacturing conditions. They collaborate with manufacturing and quality assurance departments to verify product performance through durability tests and environmental tests, and when troubles occur, they investigate causes and develop improvement measures.
Future Outlook
With the expanding demand for optical thin films in AR/VR, LiDAR, displays, optical communications, automotive sensing, etc., the needs for design engineers are steadily increasing. The adoption of AI and simulation support tools is advancing, heightening the value of personnel who can adapt to them.
