    摘要: The invention relates to methods for fabricating a semiconductor substrate. In one embodiment, the method includes providing an support that includes a barrier layer thereon for preventing loss by diffusion of elements derived from dissociation of the support at epitaxial growth temperatures; providing a seed layer on the barrier layer, wherein the seed layer facilitates epitaxial growth of a single crystal III-nitride semiconductor layer thereon; epitaxially growing a nitride working layer on the thin seed layer; and removing the support to form the substrate.

    摘要: The invention relates to methods for fabricating a semiconductor substrate. In one embodiment, the method includes transferring a seed layer on to a support substrate; and depositing a working layer on the seed layer to form a composite substrate. The seed layer is made of a material that accommodates thermal expansion of the support substrate and of the working layer. In another embodiment, the method includes providing a source substrate with a weakened zone defining a nucleation layer, bonding a support substrate to the source substrate, detaching the nucleation layer and support substrate at the weakened zone by applying laser irradiation stress, depositing a semiconductor material upon the nucleation layer, bonding a target substrate to the deposited layer and removing the support substrate and nucleation layer. The result is a semiconductor substrate that includes the layer of semiconductor material on a support or target substrate.
