Plessey's chip-scale-packaged dotLEDs for wearables nominated for Elektra Award

UK-based Plessey says that its chip-scale-packaged dotLEDs have been shortlisted in the Design Team of The Year category of the Elektra Awards. Acknowledging product innovation and business success in the industry for more than a decade, the Elektra Awards celebrates the achievements of individuals and companies across the electronics industry. The awards showcase the best new products, technology innovation and company performances of the year. 

The CSP-300's core LED chip is based on Plessey's proprietary gallium nitride on silicon (GaN-on-Si) manufacturing technology, which is fabricated on 6-inch silicon wafers. Plessey claims that this technology enables the lowest LED product cost combined with a superior thermal performance compared with competing technologies. Designed for wearable technology applications such as smart watches, mobile backlighting and textiles, the dotLED has a footprint of only 0.55mm x 0.55mm and offers multiple whites, red, green and blue colours with various levels of light output.

"Demand for wearable technology is increasing, and LED technology plays an increasingly major role in product realization in this sector," says Plessey's LED packaging specialist Zainul Fiteri. "The CSP-300 is designed to deliver the best, smallest-size, lowest-cost LED solution and therefore fulfil the needs of this emerging market," he adds. "The manufacturing process uses wafer-level packaging with through-silicon via (TSV) technology - a greatly simplified process compared to conventional LED packaging technologies with a shorter manufacturing cycle time, very high throughput and hence reduced cost. The unique combination of the 6-inch silicon LED growth wafer process and the 8-inch silicon packaging wafer process results in significant economies of scale in manufacturing," Fiteri continues. 

"The dotLED is the smallest wearable LED in the market, with a true optical centre in a square form factor," Fiteri says. "This feature has critical impact in the end application, for example when it is desired to build a miniature array of devices in a display application. Competitive products with non-optimal centering and larger footprints do not allow the same small-form-factor arrays to be manufactured. With our design and manufacturing technology, and future evolution of circuit assembly techniques, future products could be as small as a 0.27mm square footprint with the same performance," he reckons. 

Selected by an independent panel of judges, the Elektra Awards winners will be announced on 24 November at a ceremony at The Lancaster Hotel in London. Other companies shortlisted within the category Design Team of The Year are ByteSnap Design, ESCATEC, AndersDX and Peratech.
