Micro-LED Production

HC Semitek installs the production equipment at its 6-inch microLED epiwafer fab in Jinwan

In August 2023, China-based HC Semitek started building its microLED epiwafer production line in Jinwan District, Zhuhai, China. The first phase of the $700 million microLED fab is expected to enter production by the end of 2024.

HC Semitek announced a few days ago that it has moved in and installed the production equipment in its new line. The company says it is on track to produce the first sample wafers in Q3 2024, and mass production is expected by the end of the year. The investment in the first phase will total $275 million USD.

STRATACACHE to integrate Lumiode's backplane deposition technology in its microLED fab in Eugene, Oregon

US-based signage leader STRATACACHE announced that it has signed a strategic research and IP licensing agreement with US-based Lumiode that will enable STRATACACHE to integrate Lumiode's technology in its upcoming E4 microLED production line in Eugene, Oregon.

Lumiode's technology enables the deposition of an active matrix backplane directly on the LED structure. Lumiode's technology enables the production of both large-area displays and small microdisplays, and it is likely that STRATACACHE is interested in the former.

Comptek's CEO gives us the latest updates and his views on the microLED industry, towards Comptek's upcoming talk at MicroLED-Connect

Finland-based Comptek Solutions develops passivation technology solutions for III-V compound semiconductor materials and devices, based on its novel surface treatment process. Comptek's research leader Marjukka Tuominen will give a talk at the upcoming MicroLED-Connect startup showcase event on February 2024, and Comptek's CEO and co-founder, Vicente Calvo Alonso, was kind enough to send us a short update on the company's technology and status, and his views on the microLED industry and market.

Q: Hello Vicente, thank you for your time. Can you tell us a bit about Comptek, your technology and current status?

Comptek Solutions is an expert in passivation technology solutions for III-V compound semiconductor materials and devices. With our novel surface treatment process, KontroxTM, we are able to control how the oxidation process happens on the surface of the compound materials, and for the first time ever, we can create high quality, crystalline native oxides which are thermodynamically stable and present very low levels of surface state defects.

Micro-CPV: a promising new solar technology that may benefit from microLED production processes

Researchers from the  Universidad Politécnica de Madrid and MIT, published a review article on Micro-Scale Concentrating Photovoltaics, or micro-CPV, a new technology that uses miniaturized solar panels and optics that concentrate the sun's energy into these micro panels. The benefits of micro-CPV compared to normal solar panels include potentially lower cost (much less solar absorption area), better thermal management, shorter optical path and lower resistive losses.

There are many challenges yet before micro-CPVs can be produced in large volume and at competitive prices. Interestingly, microLED production processes can be applied to the production of micro-CPVs, as these solutions can be seen like inverted technologies - tiny devices that either absorb or emit light.
