    Abstract: The disclosure relates to an apparatus and a method for vector scattering parameter (s-parameter) measurements, and more particularly, to an apparatus and a method for providing a simple, low cost solution for tests requiring vector s-parameter measurements. The apparatus includes a source which provides an input signal, a divider which splits the input signal to a reference signal and a testing signal, a phase shifter which shifts the reference signal by a first phase and outputs a phase shifted signal, a device under test (DUT) which shifts the testing signal by a second phase and outputs a DUT shifted signal, a combiner which combines the phase shifted signal and the DUT shifted signal into a combined signal, and a detector which detects a product of the phase shifted signal and the DUT shifted signal.

    Abstract: Methods for forming a device structure and device structures using a silicon-on-insulator substrate that includes a high-resistance handle wafer. A doped region is formed in the high-resistance handle wafer. A first trench is formed that extends through a device layer and a buried insulator layer of the silicon-on-insulator substrate to the high-resistance handle wafer. The doped region includes lateral extension of the doped region extending laterally of the first trench. A semiconductor layer is epitaxially grown within the first trench, and a device structure is formed using at least a portion of the semiconductor layer. A second trench is formed that extends through the device layer and the buried insulator layer to the lateral extension of the doped region, and a conductive plug is formed in the second trench. The doped region and the plug comprise a body contact.

    Abstract: Embodiments of the present invention provide an apparatus and method for wafer thinning endpoint detection. Embodiments of the present invention utilize through silicon via (TSV) structures formed in the wafer. A specially made wafer handle is bonded to the wafer. Conductive slurry is used in the wafer backside thinning process. The wafer handle provides electrical connectivity to an electrical measurement tool, and conductive posts in the wafer handle are proximal to a test structure on the wafer. A plurality of electrically isolated TSVs is monitored via the electrical measurement tool. When the TSVs are exposed on the backside as a result of thinning, the conductive slurry shorts the electrically isolated TSVs, changing the electrical properties of the plurality of TSVs. The change in electrical properties is detected and used to trigger termination of the wafer backside thinning process.
