Abstract:
A method for layer transfer using a boron-doped silicon germanium (SiGe) layer includes forming a boron-doped SiGe layer on a bulk silicon substrate; forming an upper silicon (Si) layer over the boron-doped SiGe layer; hydrogenating the boron-doped SiGe layer; bonding the upper Si layer to an alternate substrate; and propagating a fracture at an interface between the boron-doped SiGe layer and the bulk silicon substrate. A system for layer transfer using a boron-doped silicon germanium (SiGe) layer includes a bulk silicon substrate; a boron-doped SiGe layer formed on the bulk silicon substrate, such that the boron-doped SiGe layer is located underneath an upper silicon (Si) layer, wherein the boron-doped SiGe layer is configured to propagate a fracture at an interface between the boron-doped SiGe layer and the bulk silicon substrate after hydrogenation of the boron-doped SiGe layer; and an alternate substrate bonded to the upper Si layer.
