This paper reports the first demonstration of 300 mm In0.53Ga0.47As-on-insulator (InGaAs-OI) substrates. The use of direct wafer bonding and the Smart Cut (TM) technology lead to the transfer of high quality InGaAs layer on large Si wafer size (300 mm) at low effective cost, taking into account the reclaim of the III-V on Si donor substrate. The optimization of the three key building blocks of this technology is detailed. (1) The III-V epitaxial growth on 300 mm Si wafers has been optimized to decrease the defect density. (2) For the first time, hydrogen-induced thermal splitting is made inside the indium phosphide (InP) epitaxial layer and a wide implantation condition ranges is observed on the contrary to bulk InP. (3) Finally a specific direct wafer bonding with alumina oxide has been chosen to avoid outgas diffusion at the alumina oxide/III-V compound interface. (C) 2016 The Japan Society of Applied Physics
