Improving GaN Production
The system combines a high-speed infrared pyrometer and an LED-based reflectometer to measure target reflectivity and radiance. This method allows for real-time correction of emissivity during epitaxial deposition, giving reliable and repeatable temperature readings. The unit enables tuning of the reactor to ensure repeatable growth temperatures over a full series of production runs and a rapid return to production after maintenance.
Software enables analysis of growth rates and buffer layer and ternary material composition to improve quality and throughput levels on subsequent runs.
The original RealTemp system was designed to provide production-level in-situ temperature measurement for As/P applications. The RealTemp 200 is aimed at higher yield for GaN on sapphire or silicon carbide substrates device production and can be integrated into Emcore's GaNzilla tool. The company expects the new technology to be adaptable to all of the nearly 200 GaN systems deployed worldwide.
Early success had been achieved with a major LED producer that was selected as a beta test site. This manufacturer has ordered additional units for their existing systems.
AngelTech Live III: Join us on 12 April 2021!
AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!
Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.
2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.
We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.
We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.
Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.
Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.
So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
