Abstract: A semiconductor structure includes a dielectric layer over a substrate, a via conductor over the substrate and in the dielectric layer, and a first graphene layer disposed over the via conductor. In some embodiments, a top surface of the via conductor and a top surface of the dielectric layer are level. In some embodiments, the first graphene layer overlaps the via conductor from a top view. In some embodiments, the semiconductor structure further includes a second graphene layer under the via conductor and a third graphene layer between the dielectric layer and the via conductor. In some embodiments, the second graphene layer is between the substrate and the via conductor.

Abstract: The present invention provides a double parallelogram vertical lifting device comprising a linkage mechanism and a pushing device. The linkage mechanism comprises a first shaft seat, a second shaft seat, a third shaft seat, an upper support unit movably coupled to the first shaft seat and the second shaft seat on both ends, and a lower support unit movably coupled to the second shaft seat and the third shaft seat on both ends. The upper support unit is provided with a first gear, and the lower support unit is provided with a second gear that meshes with the first gear. The pushing device has one end set on the upper support unit and the other end set on the lower support unit. The invention utilizes the interaction of the first gear and the second gear to generate a reaction force, which enables the lower support unit to cooperate with the upper support unit to move up and down synchronously, and achieves the effect of simple structure and large load capacity.

Abstract: The present invention teaches a tower for hydropower, comprising a main structure comprising an outflow tank at a top end and a collection tank at a bottom end of the main structure; a transmission device configured in the main structure; a plurality of water basins configured on the transmission device; and a generator device is coupled to the transmission device. Water is introduced into an outflow tank, and then into water basins so that the water basins are pulled downward by gravity so as to convert potential energy into kinetic energy that drives a transmission device and a generator device to produce electrical energy. Through this simple tower, a limited amount of water is used for electricity generation of enhanced efficiency, with fast initiation and low operating reserve.
