Veeco and ALLOS Technical Collaboration Accelerates the Pace for 200 mm GaN-on-Silicon microLED Applications for Leading Glob...
November 08 2018 - 8:00AM
Veeco Instruments Inc. (Nasdaq: VECO) and ALLOS Semiconductors GmbH
announced today the completion of another phase of their mutual
effort to provide the industry with leading GaN-on-Silicon epiwafer
technology for microLED production. The purpose of the companies’
most recent collaboration was to demonstrate the reproducibility of
ALLOS’ 200 mm GaN-on-Si epiwafer technology on Veeco’s Propel®
MOCVD reactor when producing epiwafers for many prominent global
consumer electronics companies.
“To bring microLED technology into production, simply presenting
champion values for a single metric is insufficient. It is
essential to achieve the whole set of specifications for each wafer
with excellent repeatability and yield,” said Peo Hansson, Ph.D.,
senior vice president and general manager of Veeco’s Compound
Semiconductor business unit. “This successful joint effort
reaffirms the power of combining Veeco’s superior MOCVD expertise
with ALLOS’ GaN-on-Silicon epiwafer technology to provide customers
a novel, proven and reliable approach to accelerate microLED
adoption.”
Sorting and binning are standard methods to achieve wavelength
consistency for conventional LEDs. But microLEDs are too small and
numerous to be sorted and binned; therefore, the uniformity of the
epitaxial deposition is even more critical. The most important
success factor for turning the promise of microLED displays into
mass production reality is to achieve extremely good emission
wavelength uniformity, which eliminates the need to test and sort
individual microLED chips. Depending on the application and mass
transfer approach, the target requirements of the industry are
between +/-1 nm and +/-4 nm bin (min/max) on the epiwafer.
Through this collaborative project, Veeco and ALLOS further
improved the critical wavelength uniformity with the best wafer
having a standard deviation of just 0.85 nm, representing an
industry first on a production system.
“Veeco and ALLOS validated wafer-to-wafer reproducibility with
an average wavelength standard deviation for all wafers of 1.21 nm
and the peak wavelength within a +/- 0.5 nm range. With these
results we made another significant leap towards the +/-1 nm bin
goal on an epiwafer,” said Burkhard Slischka, CEO of ALLOS. “Our
technology is already available on 200 mm wafer diameter, which
enables the use of low-cost and high yield silicon lines for
microLED chip production. Additionally, we have a clear roadmap to
enable 300 mm.”
Innovators in display technology are focusing on microLED as the
next significant technological shift. According to research firm
Yole Développement, the market for microLED displays could
potentially reach 330 million units by 2025. This optimism is
fueled by the promise of microLED technology (sub-100 micrometer
edge length), which is considered the critical enabler to achieving
the ultimate display with much lower power consumption. However,
development of such displays has been hindered by high material
costs and low yield and throughput of microLED mass transfer
technology. This joint technical effort effectively addresses these
challenges as Veeco and ALLOS continue to work with customers to
further improve GaN-on-Si epiwafer and microLED mass transfer
technology.
Veeco and ALLOS will showcase details of their breakthrough
achievements at the International Workshop on Nitride
Semiconductors (IWN) in Kanazawa, Japan on Nov. 12, 2018.
