Some says “if it can be made on Silicon, it will be made on silicon”. Is that true for GaN too ? And if so, can it be applied in all GaN-based applications: LED, power, RF and laser?
Among all widely diffused compound semi materials, GaN is the only one for which bulk crystal remains extremely expensive. Therefore, any alternate substrate to grow GaN epi is strongly welcomed. Silicon is seen as one of the most promising solutions as it offers large diameter, low cost and existing CMOS manufacturing capabilities all over the world.
RF was the first application trying to capture the added-value of GaN-on-Si for commercial products (Nitronex 1999). LED then joined the battlefield with Lattice Power then more recently Toshiba and Bridgelux, aiming to displace sapphire domination. In power switching, pioneers were International Rectifier and EPC, followed by numerous new entrants since then, all targeting low cost, high power conversion efficiency devices. Only lasers seem linked to bulk GaN forever.
This presentation will highlight the remaining challenges to spread GaN-on-Si over all possible applications, from a market, technology, industry and IP viewpoints.
