BelGaN — A unique Wide-Band-Gap semiconductor foundry in Belgium, driving the "GaN Valley" in Europe and beyond

The presentation will start with introducing BelGaN, a new semiconductor company that originated in Feb 2022 from the acquisition of parts of onsemi in Belgium. BelGaN will bring a leading automotive qualified open foundry to the WBG ecosystem, to enable European and global customers developing and manufacturing unique automotive and multi-market solutions for a sustainable electrified future. In the 2nd part of the presentation we will present 'GaN-Valley', a WBG ecosystem that will accelerate the introduction and growth of disruptive technologies like GaN into multi-markets such as chargers, automotive, datacom, industrial, renewal energy etc. 50-yr old Si-Valley has been instrumental to initiate and grow a datadriven industry, fuelled by applications such as computers, mobile communication, internet, IOT, Al, autonomous systems, that generate an huge data-explosion (IOOX over 10yr) enabling the digitalized society. Similarly, GaN-Valley, as a WBG ecosystem, will enable the electricity-explosion (2x over 20yr) caused by the electrification of many systems (such as e-Vehicles), while reducing carbon-emission. As such WBG-technologies will be instrumental to build a sustainable green society. We will present the current status and opportunities of 'GaN-Valley', and end with a call for collaboration to enable the acceleration of WBG introduction to build a sustainable and more autonomous future in Europe.
