Semi-automated and fully automated systems for high and low-volume production environments. Toho high-performance metrology systems provide thin film & materials characterization systems used to monitor film stress, physical, optical, electrical and material characteristics of HB-LED, compound semiconductor, strained silicon and silicon-on-insulator (SOI) devices, including composition, crystal structure, layer thickness, dopant concentration, contamination and electron mobility.
Lens Alignment Station
The Lens Alignment Station (LAS™) employs a focused laser beam in reflection to measure the surface decenter and tilt. Following reflection from the lens surface, the laser beam is focused to a bright spot on the LAS™ camera at two distinct vertical locations - Normal (or Cat’s Eye) and Confocal. The Normal signal occurs when the focused laser reflects directly from the lens surface. The Confocal signal occurs when the laser focus is coincident with the Radius of Curvature (ROC) of the surface. This will be above the surface for a concave surface and below the surface for a convex surface.
