Veeco launches K475i As/P MOCVD system

Epitaxial deposition and process equipment maker Veeco Instruments Inc of Plainview, NY, USA has launched the TurboDisc K475i arsenic phosphide (As/P) metal-organic chemical vapor deposition (MOCVD) system for the production of red, orange, yellow (R/O/Y) light-emitting diodes, as well as multi-junction III-V solar cells, laser diodes and transistors.

"Veeco continues to drive innovation with MOCVD technology that enables us to lower manufacturing costs and increase production with systems that are reliable, flexible and easy to use," comments Shuangxiang Zhang, general manager of Yangzhou Changelight Co Ltd. "The K475i quickly achieved unparalleled yield and brightness that will allow us to meet the growing demand for red, orange and yellow LEDs as well as other As/P-based devices," he adds.

According to market research firm Strategies Unlimited, R/O/Y LED demand is expected to grow at a 10% compound annual rate through 2023. This demand for red, orange and yellow LEDs is being driven by signage, automotive, display and general lighting applications, as well as the emergence of new applications such as wearable smart devices. 

Incorporating proprietary TurboDisc and Uniform FlowFlange MOCVD technologies, the new K475i system enables users to reduce LED cost per wafer by up to 20% compared with alternative systems through what is reckoned to be higher productivity, best-in-class yields and reduced operating expenses.

"The new K475i is built upon production proven technologies that are incorporated into all of our industry-leading MOCVD systems," says James T. Jenson, senior VP & general manager, Veeco MOCVD Operations, who highlights Changelight's rapid qualification of the beta system. "We have already seen strong industry interest in the K475i," he adds.

Veeco says that its proprietary Uniform FlowFlange technology produces films with very high uniformity and improved within-wafer and wafer-to-wafer repeatability resulting in what is reckoned to be the industry's lowest cost of ownership. The patented technology is said to provide ease-of-tuning for fast process optimization and fast tool recovery time after maintenance, enabling the highest productivity for applications such as lighting, display, solar, laser diodes, pseudomorphic high-electron-mobility transistors (pHEMTs) and heterojunction bipolar transistors (HBTs).
