1. A method of forming a strained channel for a field effect transistor, comprising:

  • removing a sacrificial slab from a stack of a channel block on the sacrificial slab, and a stressor island on the channel block, wherein the sacrificial slab is between the channel block and a substrate, wherein the sacrificial slab has a single crystal structure, and wherein the channel block physically bonds to the substrate surface; and

    heat treating the channel block and substrate to chemically bond the channel block to the substrate surface.
