    摘要: The crystal orientations of monocrystalline semiconductor wafers may be varied by four parameters. The first parameter is the type of crystal seed used to grow the monocrystalline semiconductor ingot from which the wafers are cut. The second parameter is the angle at which the wafer is sliced from the ingot. The third parameter is the crystal plane towards which the wafer is cut. And, the fourth parameter is the position of the orientation indication feature that is used to align the wafer during processing. Different combinations of these parameters provide variations of non-standard crystal orientations of monocrystalline semiconductor wafers and semiconductor-on-insulator substrates such as silicon-on-insulator.

    摘要: A method of forming a silicon-on-insulator wafer begins by providing a silicon wafer having a first surface. An ion implantation process is then used to implant oxygen within the silicon wafer to form an oxygen layer that is buried within the silicon wafer, thereby forming a silicon device layer that remains substantially free of oxygen between the oxygen layer and the first surface. An annealing process is then used to diffuse nitrogen into the silicon wafer, wherein the nitrogen diffuses into the silicon device layer and the oxygen layer. Finally, a second annealing process is used to form a silicon dioxide layer and a silicon oxynitride layer, wherein the second annealing process causes the implanted oxygen to react with the silicon to form the silicon dioxide layer and causes the diffused nitrogen to migrate and react with the silicon and the implanted oxygen to form the silicon oxynitride layer.

    摘要: A method and article to provide a three-dimensional (3-D) IC wafer process flow. In some embodiments, the method and article include bonding a device layer of a multilayer wafer to a device layer of another multilayer wafer to form a bonded pair of device layers, each of the multilayer wafers including a layer of silicon on a layer of porous silicon (SiOPSi) on a silicon substrate where the device layer is formed in the silicon layer, separating the bonded pair of device layers from one of the silicon substrates by splitting one of the porous silicon layers, and separating the bonded pair of device layers from the remaining silicon substrate by splitting the other one of the porous silicon layers to provide a vertically stacked wafer.
