Kyoreca developed a new process to grow low-defect microLED GaN devices

Kyocera Corporation announced that it has successfully developed a new process technology to produce microLED (and micro-laser) devices. The process is based on lateral growth of GaN layer on a silicon wafer, in a way that limits defects in most of the area.

The basic process has three steps. First you grow a GaN layer on silicon. The second step is to apply a mask with a has a horizontal gap. The third step is to continue growing the GaN layer. The defects are concentrated in the opening nucleus, but the rest of the growth area remains almost defect free. The actual microLED devices are fabricated from the low-defect region.

STRATACACHE to build the first MicroLED production line in the US, mass production expected by 2023

Global digital signage solution provider STRATACACHE is embarking on a project to construct a microLED display production line in Eugene, Oregon. The company aims to start production in this fab at around 2022-2023, with plans to adopt these microLED displays in its own solutions.

The new factory (E4) will be a complete microLED production line, from epiwafer (on 300 mm silicon wafers), through transfer process and to final module assembly. The company plans to produce a wide range of displays, from tablet-sized panels to large-area displays. Some of these displays will be flexible and transparent as the company sees a market demand for such technologies. The yearly capacity of the E4 is expected to start at a 1 million square meters per year.
