Abstract: Structures with doping free connections and methods of fabrication are provided. An exemplary structure includes a substrate; a first region of a first conductivity type formed in the substrate; an overlying layer located over the substrate; a well region of a second conductivity type formed in the overlying layer; a conductive plug laterally adjacent to the well region and extending through the overlying layer to electrically contact with the first region; and a passivation layer located between the conductive plug and the well region.

Abstract: According to one example, a semiconductor device includes a substrate and a fin stack that includes a plurality of nanostructures, a gate device surrounding each of the nanostructures, and inner spacers along the gate device and between the nanostructures. A width of the inner spacers differs between different layers of the fin stack.

Abstract: A seat comprises a cushion, a pair of backrests, a pair of bolsters, and a pair of armrest pads. The cushion has a width of double seat. Both the bolster and the backrest have a width of single seat. A front face of the bolster has a concave arc portion, and a back face thereof has a slanting arc portion. The bolsters can be turned 180 degrees. A fixing device joins the bolster and the backrest. A joining device is disposed at the adjoining position of the two backrests. An armrest is joined at each side of the cushion. A pad is joined on the armrest to form the armrest pad. The pad and the armrest are joined by a turn control device so that the pad can be turned 90 degrees, hence facilitating use of a single seat. A double seat is obtained by restoring the armrest pads.

Abstract: A mice-catching cage including a plurality of compartments, which are disposed at various levels and are provided with a one-way guide path which is in turn provided with an entrance pathway. The entrance pathway is provided in the bottom with a support plate on which an inclined door plate is supported. The inclined door plate is provided in an underside with a weight attached thereto for tilting the inclined door plate. The entrance pathway is provided in the top wall with a stop plate for forming a one-way path along with the inclined door plate upon entrapment of a mouse.

Abstract: A connector assembly for an upright shaft of a beach umbrella, includes first and second stem members and a tubular connecting member. The upright shaft portion includes a lower shaft portion and a hollow upper shaft portion. The lower shaft portion extends in an axial direction and is provided with an upwardly opened annular end portion. The upwardly opened annular end portion has a first inner annular wall with a first dimension. The upper shaft portion is provided with a downwardly opened annular end portion which can brought in the axial direction to connect with the upwardly opened annular end portion. The downwardly opened annular end portion has a second inner annular wall with a second dimension. The first and second stem members have first lower and upper stem portions press-fitted into the upwardly and downwardly opened end portions of the lower and upper shaft portions.
