InnoLas Installs Laser Scribers At 100 MW Korean CIGS Plant

The current installations are a further step in the successful roll-out of the firm's laser scriber systems for CIGS thin film solar cells and other semiconductors such as cadmium telluride
German company InnoLas Systems recently installed its pioneering P1, P2 and P3 laser scribers at a 100 MW CIGS fab in Korea.

This innovative laser technology for P2 scribing of thin film solar cells is suited for use on the structures of CIGS semiconductors and has so far been delivered to four different customers. These laser patterning tools support 250 MW production volume globally.

InnoLas CEO Richard Grundmüller says, "The current installations are a further step in the successful roll-out of our laser scriber systems for thin film solar cells. Not only for the processing of CIGS but also for other semiconductors, e.g. CdTe cells, the InnoLas laser systems have become must-have production tools. Up to September this year we have already developed, built and installed P1, P2 and P3 scribing systems for a fab capacity of 300 MW."

InnoLas also offers advanced laser systems for R&D applications.

The company has received an order for a multi-functional laser tool, tailor-made for the rigorous requirements in modern photovoltaic development labs. This system can process any individual pattern either from the film side or from the glass side with multiple wavelengths.

All layers (P1, P2 and P3) can be laser scribed, and the processing side and process parameters are selected through simple menu commands. Mechanical scribing (P2, P3) is available on the same system. Highlights include integrated In-situ metrology, giving 100 percent control over scribe performance and enabling the user to optimise process parameters on the fly.

The firm will be showcasing its products at the EU PVSEC trade show at stand 3.0/G17b, Frankfurt a. M., Germany, between September 24th and 28th.


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.
