Abstract:
A foldable trolley for supporting a stretcher, including a foldable frame having a pair of vertical support members that are rigidly secured to each other by a first horizontal member, and a pair of elongated frame members that are pivotally secured to the pair of vertical support members at their respective bottom ends and rigidly connected by a second horizontal member, a wheel assembly including a first wheel and a second wheel rotatably attached to a corresponding vertical support member, and a plurality of clamp assemblies, each clamp assembly being mounted to a top end of each vertical support member and each elongated frame members, each clamp assembly being movable between a closed position and an open position.
Abstract:
A method is provided for fabricating a semiconductor device. A semiconductor substrate is provided. A first high-k dielectric layer is formed on the semiconductor substrate. A first treatment is performed on the high-k dielectric layer. In an embodiment, the treatment includes a UV radiation in the presence of O2 and/or O3. A second high-k dielectric layer is formed on the treated first high-k dielectric layer. A second treatment is performed on the second high-k dielectric layer. In an embodiment, the high-k dielectric layer forms a gate dielectric layer of a field effect transistor.
