The donor substrate comprises a monocrystalline carrier substrate, an intermediate etch-stop layer, and a monocrystalline semiconductor layer. The monocrystalline semiconductor layer is transferred from the donor substrate to the receiving substrate. Trench isolations are formed to cut a portion from a layer stack including the transferred monocrystalline semiconductor layer, the dielectric layer, and the strained semiconductor material layer.

Techniques for joining dissimilar materials in microelectronics are provided. Example techniques direct-bond dissimilar materials at an ambient room temperature, using a thin oxide, carbide, nitride, carbonitride, or oxynitride intermediary with a thickness between 100-1000 nanometers. The intermediary may comprise silicon. The dissimilar materials may have significantly different coefficients of thermal expansion (CTEs) and/or significantly different crystal-lattice unit cell geometries or dimensions, conventionally resulting in too much strain to make direct-bonding feasible. A curing period at ambient room temperature after the direct bonding of dissimilar materials allows direct bonds to strengthen by over 200%. A relatively low temperature anneal applied slowly at a rate of 1° C. temperature increase per minute, or less, further strengthens and consolidates the direct bonds. The example techniques can direct-bond lithium tantalate LiTaO.sub.3 to various conventional substrates in a process for making various novel optical and acoustic devices.
