While first commercial 5G wireless networks are going live, imec prepares the next generation mobile handsets – for 5G and beyond-5G applications. In these handsets, front-end modules will have to operate at mm-wave frequencies and combine high speed with high output power. In an article that appeared in Compound Semiconductor, Abhitosh Vais, researcher at imec, introduces functional III-V heterojunction bipolar transistors (HBTs) on 300mm Si substrates as one of the possible routes towards 5G and beyond front-end modules. Key to the results is the ability to grow defect-free III-V layers on 300mm Si substrates.
