  • Patent number: 9362418
    Abstract: Semiconductor structures that include bodies of a semiconductor material spaced apart from an underlying substrate. The bodies may be physically separated from the substrate by at least one of a dielectric material, an open volume and a conductive material. The bodies may be electrically coupled by one or more conductive structures, which may be used as an interconnect structure to electrically couple components of memory devices. By providing isolation between the bodies, the semiconductor structure provides the properties of a conventional SOI substrate (e.g., high speed, low power, increased device density and isolation) while substantially reducing fabrication acts and costs associated with such SOI substrates. Additionally, the semiconductor structures of the present disclosure provide reduced parasitic coupling and current leakage due to the isolation of the bodies by the intervening dielectric material.

  • Patent number: 8143167
    Abstract: Trench isolation structures and methods to form same for use in the manufacture of semiconductor devices are described. The trench isolation structures are formed using several processing schemes that utilize disclosed dry etching processes to form a significant depth ? between an array trench depth and a periphery trench depth. One etching method creates a trench delta depth utilizing a single dry etch step, while two other etching methods create a trench ? depth by utilizing three dry etch steps.
