With a growing number of applications for High Brightness LEDs, manufacturers are looking for better strategies to increase yield and improve performance. Today HB-LEDs have made their way into backlighting of notebook computers and LCD televisions, as well as into other diverse applications from cell phones to flashlights to automobile headlights. With legislation targeting the phase out of incandescent lighting and challenging restrictions of toxic materials such as those used in compact fluorescent lighting, volumes of HB- LEDs targeting residential and industrial lighting are likely to expand rapidly in the near future.
As the HB-LED process flow becomes increasingly complex, it drives the requirement for improved control of critical dimensions in the patterning process. Nanometrics offers a comprehensive line of products and technologies for HB-LED metrology and process control. Nanometrics PL systems provides a combination of metrology technologies to support both process development and production control.
