    摘要: A bearing assembly retainer ring has pockets for holding cylindrical rollers in arcuately spaced relationship about a central axis of the retainer ring. Each pocket has two end faces that are spaced axially of the retainer ring and two side faces that are spaced laterally of the axial spacing between the two end faces. The pocket extends radially through inner and outer peripheral edges of the retainer ring to receive a roller therein having a diameter which is greater than the radial span of the pocket end faces so that the roller extends beyond the inner and outer peripheral edges of the retainer ring. The axial spacing between the pocket end faces is slightly greater than the axial length of the roller to provide restricted clearances between the ends of the roller and the end faces of the pocket when the roller is centered within the pocket. Chamfers are provided on the end faces of the pockets at the inner and outer peripheral edges thereof. These chamfers enable the roller to pivot within the pocket from a position wherein the roller is aligned axially between the pocket end faces to a cocked position wherein both end faces of the pocket contact the roller and/or the side faces of the pocket contact the roller to resist further pivotal movement.

    摘要: Disclosed are embodiments of a semiconductor structure, a design structure for the semiconductor structure and a method of forming the semiconductor structure. The embodiments reduce harmonics and improve isolation between the active semiconductor layer and the substrate of a semiconductor-on-insulator (SOI) wafer. Specifically, the embodiments incorporate a trench isolation region extending to a fully or partially amorphized region of the wafer substrate. The trench isolation region is positioned outside lateral boundaries of at least one integrated circuit device located at or above the active semiconductor layer of the SOI wafer and, thereby improves isolation. The fully or partially amorphized region of the substrate reduces substrate mobility, which reduces the charge layer at the substrate/BOX interface and, thereby reduces harmonics. Optionally, the embodiments can incorporate an air gap between the wafer substrate and integrated circuit device(s) in order to further improve isolation.

    摘要: A semiconductor structure includes a multi-layer spacer located adjacent and adjoining a sidewall of a topographic feature within the semiconductor structure. The multi-layer spacer includes a first spacer sub-layer comprising a deposited silicon oxide material laminated to a second spacer sub-layer comprising a material that is other than the deposited silicon oxide material. The first spacer sub-layer is recessed with respect to the second spacer sub-layer by a recess distance of no greater than a thickness of the first spacer sub-layer (and preferably from about 50 to about 150 angstroms). Such a recess distance is realized through use of a chemical oxide removal (COR) etchant that is self limiting for the deposited silicon oxide material with respect to a thermally grown silicon oxide material. Dimensional integrity and delamination avoidance is thus assured for the multi-layer spacer layer.
