Among the most exciting alternatives is illumination using high-brightness white LEDs. LED laser scribing technology is helping lead the way for great advancements in the area of optoelectronic devices. White LED diode technology is one of the leading applications benefiting from LED scribing. In fact, it is estimated that by 2013 the demand for LEDs for solid-state lighting (SSL) will represent nearly $1 billion. LEDs, which are manufactured from hard materials, present challenges for device singulation. In particular, the use of mechanical sawing alone often produces cracks leading manufacturers to use of wide streets between adjacent circuits. An ideal alternative to mechanical saws is to utilize fine scribes to create narrow laser scribes that will prevent crack propagation during processing and result in higher yields. This leads to the need for high precision laser solutions. The Spectra-Physics Advantage Spectra-Physics has long been recognized as the laser technology leader serving customers around the world. Spectra-Physics designs, develops, and manufactures premier lasers for a variety of commercial and industrial markets, including LED scribing. Spectra-Physics offers a wide range of tools for both scribing and dicing and remains the industry leader for innovative and high precision lasers such as the Tristar ™, Navigator ™, and HIPPO ™ family of high-power nanosecond lasers, and the Vanguard ™ series of picosecond lasers. When ultrafast (femtosecond) processing is necessary, the Solstice® one-box amplifier provides 100 fs pulses in a fully-automated, rugged architecture that is specifically designed for industrial applications. When scribing LED substrates, the short pulse widths and high peak power of Spectra-Physics’ lasers result in cleaner scribing, less displaced material, and less thermal damage to the substrate. Spectra-Physics also offers a depth of applications knowledge and experience to help maximize the efficiency of your process. Each laser comes with the confidence of having Newport’s proven global service and support team. WEB Download the complete brochure. Please click here.
