Self-assembled monolayer assisted bonding of Si and InP

A versatile procedure for the low-temperature bonding of silicon and indium-phosphide to silicon is proposed and demonstrated. The procedure relies on the deposition and functionalization of self-assembled, single molecular layers on the surface of one substrate, and the subsequent attachment of the monolayer to the surface of the other substrate with or without its own monolayer coating. The process is applicable to the fabrication of hybrid-silicon, active photonic devices. (C) 2012 Optical Society of America
