    摘要: Techniques for employing different channel materials within the same CMOS circuit are provided. In one aspect, a method of fabricating a CMOS circuit includes the following steps. A wafer is provided having a first semiconductor layer on an insulator. STI is used to divide the first semiconductor layer into a first active region and a second active region. The first semiconductor layer is recessed in the first active region. A second semiconductor layer is epitaxially grown on the first semiconductor layer, wherein the second semiconductor layer comprises a material having at least one group III element and at least one group V element. An n-FET is formed in the first active region using the second semiconductor layer as a channel material for the n-FET. A p-FET is formed in the second active region using the first semiconductor layer as a channel material for the p-FET.

    摘要: A method of removing a semiconductor device layer from a base substrate is provided that includes providing a crack propagation layer on an upper surface of a base substrate. A semiconductor device layer including at least one semiconductor device is formed on the crack propagation layer. Next, end portions of the crack propagation layer are etched to initiate a crack in the crack propagation layer. The etched crack propagation layer is then cleaved to provide a cleaved crack propagation layer portion to a surface of the semiconductor device layer and another cleaved crack propagation layer portion to the upper surface of the base substrate. The cleaved crack propagation layer portion is removed from the surface of the semiconductor device layer and the another cleaved crack propagation layer portion is removed from the upper surface of the base substrate.

    摘要: A multilayered stack including alternating layers of sacrificial material layers and semiconductor material layers is formed on a base substrate. The thickness of each sacrificial material layer of the stack increases upwards from the sacrificial material layer that is formed nearest to the base substrate. Because of this difference in thicknesses, each sacrificial material layer etches at different rates, with thicker sacrificial material layers etching faster than thinner sacrificial material layers. An etch is performed that first removes the thickest sacrificial material layer of the multilayered stack. The uppermost semiconductor device layer within the multilayered stack is accordingly first released. As the etch continues, the other sacrificial material layers are removed sequentially, in the order of decreasing thickness, and the other semiconductor device layers are removed sequentially.

    摘要: A method of removing a semiconductor device layer from an underlying base substrate is provided in which a sacrificial phosphide-containing layer is formed between a semiconductor device layer and a base substrate. In some embodiments, a semiconductor buffer layer can be formed on an upper surface of the base substrate prior to forming the sacrificial phosphide-buffer layer. The resultant structure is then etched utilizing a non-HF etchant to release the semiconductor device layer from the base semiconductor substrate. After releasing the semiconductor device layer from the base substrate, the base substrate can be re-used.
