JDSU shipped more than 100 Q Series UV lasers for the scribing of LED wafers

JDSU has shipped more than 100 Q Series UV lasers for the scribing of wafers used in the manufacturing of light emitting diodes (LEDs). These LEDs are used in products such as backlit LCD televisions, automotive lighting, and as a more energy efficient alternative to conventional light bulbs.

JDSU says, according to research firm iSuppli, shipments of backlit LCD TVs that use LEDs will rise to 98.8 million by 2013, accounting for about 43 percent of the global LCD TV market.

The key features of UV laser are,

High energy and beam stability to ensure consistently high yields
High pulse repetition rate and power for high throughput
Stable laser performance that reduces system maintenance over time

"The JDSU Q Series laser is the leading UV laser source for the emerging LED market based on its proven reputation over the past several years in the semiconductor and microelectronics markets," said Victor David, product line manager for the CCOP business segment at JDSU. "Growing popularity of LED-based consumer goods such as backlit TVs will continue driving demand for UV lasers."

How the LED Wafer Scribing Process Works

Material for LEDs is grown on a sapphire substrate that is then scribed and singulated, or separated into individual chips using the JDSU Q Series UV laser. The chips are then packaged into complete LEDs that are integrated into end products.
