GSU Selects Meaglow Plasma Source

The system will be used for the development of group III-nitride compound semiconductor materials
Meaglow has announced that Georgia State University (GSU) has received shipment of its patent pending hollow cathode plasma source.

The installed Meaglow plasma source extends the growth processing parameter space of GSUs presently utilised in low-pressure MOCVD reactors. This upgrades the tool so that it can produce type III-nitride materials under normal low-pressure growth conditions.



Meaglow hollow cathode plasma source

Meaglow's plasma source fosters a plasma-assisted gas phase and surface chemistry that provides a new path for the integration of dissimilar materials for ternary and quarternary III-nitride alloys.

Research in Dietz's group at GSU will study the migration enhanced afterglow chemistry and growth dynamics for III-nitride epilayers and nanocomposites. They will support Meaglow's effort in commercialising the growth technology.



Meaglow hollow cathode in use

Meaglow has previously applied its hollow cathode plasma source technology via its migration enhanced afterglow technique in the deposition of high indium content InGaN. More recently, the source has been demonstrated in a yellow LED in the green gap.

Meaglow is now focused on commercialising its hollow cathode plasma technology, and is fielding inquiries from partners interested in plasma source solutions for MBE or any surface modification to materials.



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.
