In recent years, the monolithic integration of III/V-semiconductor materials and heterostructures on CMOS-compatible (001) Si-substrate is gaining increasing interest for the realization of novel integrated circuits with improved electronic, optoelectronic or photonic functionalities.The principal challenges of the III/V-material integration on CMOS-compatible (001) Si-substrates will be reviewed and possible solutions for the high-quality deposition of III/V-layer stacks will be demonstrated for large area 300 mm (001) Si-wafers by applying low-temperature metal organic vapour phase epitaxy (MOVPE) processes. Examples of successfully developed technologies including defect-free GaP-on-Si-template wafers as well as novel lattice-matched Ga(NAsP)-based laser stacks for Si-photonics applications will be presented and discussed.
