Cree and Lextar Electronics Announce LED Cooperation
Cree to own nearly 13 percent of Lextar as part of deal
and lighting markets,” said David Su, chairman and CEO of Lextar.
He added: “We are very excited about this new cooperation with Cree. We strongly believe this new collaboration will increase the competitiveness of our products and technology, enabling both companies continued growth in the LED lighting market. Furthermore, the cross license of LED chip and component intellectual property will afford both Cree and Lextar the benefits from our product and technology development, thereby strengthening our mutual competitiveness in the global LED industry.”
The agreement has been approved by the boards of directors of both companies, and is targeted to close in Cree’s second quarter of fiscal year 2015, subject to the approval of Lextar’s shareholders and the Taiwan Investment Committee, and other customary closing conditions.
Cree, a market leader in LED lighting, and Lextar Electronics, a subsidiary of AU Optronics specialising in high-brightness LED epitaxial, chips and packages have entered into a supply agreement for sapphire-based LED chips.
As part of the agreement, Cree will invest approximately $83 million to purchase 83 million Lextar shares at a price of NT$30 per share. Lextar and Cree will also enter into a long-term LED chip supply agreement, as well as a royalty-bearing license agreement for certain Cree LED chip and component intellectual property. Upon closing of the investment, Cree will own approximately 13 percent of Lextar.
“We are excited to be strengthening our relationship with Lextar to enable growth in LEDs and Lighting,” stated Chuck Swoboda, Cree chairman and CEO. “Working with Lextar to supply high quality mid-power LED chips enables Cree to focus its resources on the high performance, high-power LED chips that differentiate Cree LEDs in the market. This approach provides the operational and financial flexibility to help Cree achieve the best return on our people and invested capital.”
“Lextar has established a strong technology position and customer base in the mid-power backlighting LED segment, while Cree has had outstanding performance in the high-power LED component
SemiLEDs introduces new Chip Scale LED Series
Combines flip chip and ReadyWhite technologies for white-chip solution
SemiLEDs Corporation has announced sampling and mass production of its newest line of white chip scale packages, the ReadyMount Enhanced CSP, or EC series.
Combining SemiLEDs’ Enhanced Flip chip (EF) approach with the company’s ReadyWhite phosphor technology, the EC is said to offer flexibility, reliability and manufacturability in a single 1.4 x 1.4mm with a low profile device of 0.4mm.
In addition to the manufacturing benefits of the chip scale package, the elimination of the wire bonds is claimed to improve the optical integration characteristics by taking advantage of the unobstructed and nearly edge-to-edge emitting chip surface which enables the die to be mounted very close together.
This simplifies the optics by eliminating the need for complex mixing lenses which are used to control ghosting and shadows in narrow beam applications. The glass top surface is also mechanically robust, and is not prone to the handling damage or stresses faced by wire-bond or flip chips with a
