In recent years, fundamental and applied technologies of LEDs were significantly improved. These achievements enhanced LEDs’ efficacy and dramatically reduced the cost of LEDs. Originally, LEDs were widely used in conventional applications, such as traffic light, indicators, and etc. Due to the cost reduction and performance improvement, LEDs are aggressively entering display backlight, mobile electronics, and general lighting applications. Because of the characteristics and advantages of LEDs, LEDs also cause great impact to these new fields. However, new products in these new applications are requested to have more functions, smaller size, and less power consumption. For satisfying with these end-product design criteria, LED components need to follow the market trend (miniaturized size, modularized system, and lower cost). Unfortunately, the current discrete LED component solution could not comply with these criteria. In this project project, the team proposed to develop the Wafer-Level LED System-in-Packaging (WL-LED-SiP) design and process platform. The team plans to adopt mobile flash module and light engine for general lighting application as project deliverable and test vehicle for platform evaluation. By promoting the platform and two applications that will be developed in this project, the team wish could assist and support manufacturers where located in Hong Kong and Pearl River Delta to upgrade their technologies and get more profit from the market.
