HC Semitek orders Aixtron systems for Micro LED displays…


Micro LED technology is poised to revolutionize the display industry. Market demand for self-emissive Micro LEDs in primary colors (RGB) is beginning to rise sharply. HC Semitek, a Chinese semiconductor technology company, will use Aixtron’s planetary systems to meet this demand.

The Chinese chipmaker now relies on AIX 2800G4-TM (IC2) and AIX G5+ C MOCVD systems – which were returned in Q4 2021, according to a press release.

HC Semitek is positioned on Micro LED technology. The technology is described to enable unparalleled pixel resolution, superior display quality, and much higher current efficiency than existing display technologies. To achieve these benefits, the next generation of LED displays will require the transfer of millions of micron-level LEDs onto a single display, which has prompted LED vendors to develop new mass transfer technologies.

To achieve this, large arrays of LEDs are extracted directly from the processed LED wafers, making any wafer grouping or sorting of defective chips obsolete. Therefore, it is essential that all produced epitaxial slices have a very tight wavelength distribution and a very low level of defects on their surfaces, which calls for new MOCVD approaches.

Aixtron’s planetary system features wafer-level control of the film surface temperature during the epitaxy process.

“AIXTRON has been our trusted and dependable partner for MOCVD solutions for 15 years. We are delighted to now strengthen our cooperation in the field of Micro LED products. AIXTRON’s planetary technology is proven for the best uniformity and low particle performance. We believe this is a key milestone for the commercialization of micro-LEDs and will strengthen HC Semitek’s leading position in the display market,” said Dr. Jianhui Zhou, CEO of HC Semitek, in the press release.
