Dark field inspection
WebFeb 18, 2024 · Bright field is the more commonly used lighting technique whereas dark field is advantageous when imaging things such as reflective surfaces and edge inspections. In this blog we will discuss the lighting requirements for Bright Field and Dark Field Illumination and their advantages and disadvantages in imaging. Bright Field Lighting Setup WebIn general, dark-field inspection is preferred for non-patterned wafer inspection since high rastering speeds are possible and this enables high wafer throughput. Patterned wafer …
