  • Patent number: 11652112
    Abstract: FET IC structures that enable formation of integrated capacitors in a “flipped” SOI IC structure made using a back-side access process, such as a “single layer transfer” (SLT) process, and which eliminate or mitigate unwanted parasitic couplings to a handle wafer. In some embodiments, a conductive interconnect layer may be patterned, pre-SLT, to form an isolated first capacitor plate. In other embodiments, pre-SLT, a conductive region of the active layer of an IC may be patterned to form an isolated first capacitor plate, with one or more interconnect layers being fabricated in position to form an electrical contact to the first capacitor plate. In either case, a post-SLT top-side layer of conductive material may be patterned to form a second capacitor plate. Couplings to the resulting capacitor structures include only external connections, only internal connections, or both internal and external connections.

  • Patent number: 11643748
    Abstract: A 4H-SiC single crystal having good morphology while preventing heterogeneous polymorphs from being mixed in regardless of the presence or absence of doping in growing a 4H-SiC single crystal by the TSSG method is obtained. When the off-angle on the grown crystal in a method for producing a SiC single crystal by a TSSG method is set to 60 to 68°, heterogeneous polymorphs are less likely to be mixed in during the growth of 4H-SiC single crystal, and if, during that period, a meltback method is used to smooth the surface of the seed crystal and then grow the crystal, it is possible to obtain a grown crystal having good morphology.
