Abstract
Different types of crystalline semiconductor regions are provided on a single substrate by forming a dielectric region within a first crystalline semiconductor region. Thereafter, a second crystalline region is positioned above the dielectric region by wafer bond techniques. In preferred embodiments, isolation structures may be formed in the first crystalline region along with the dielectric region. In particular, crystalline semiconductor regions of different crystallographic orientations may be formed, wherein a high degree of flexibility and compatibility with currently used CMOS processes is maintained.
