Abstract: A method for fabricating semiconductor devices includes forming channel regions over a substrate. The channel regions, in parallel with one another, extend along a first lateral direction. Each channel region includes at least a respective pair of epitaxial structures. The method includes forming a gate structure over the channel regions, wherein the gate structure extends along a second lateral direction. The method includes removing, through a first etching process, a portion of the gate structure that was disposed over a first one of the channel regions. The method includes removing, through a second etching process, a portion of the first channel region. The second etching process includes one silicon etching process and one silicon oxide deposition process. The method includes removing, through a third etching process controlled based on a pulse signal, a portion of the substrate that was disposed below the removed portion of the first channel region.

Abstract: Lifting equipment for lifting a waffle slab used in a construction includes a main body bracket, a sliding member and a plurality of clamping mechanisms for clamping the waffle slab. The main body bracket has a through hole in a center thereof. The sliding member is slidably disposed in the through hole of the main body bracket. The sliding member includes an engagement member located at the top of the sliding member, a shaft portion connected to the bottom of the engagement member and slidably disposed in the through hole of the main body bracket, a sleeve fitted to an outer circumference of the shaft portion, and a flange fixed to the bottom of the shaft portion for preventing the sleeve from moving downward.

Abstract: The present application relates to lifting equipment for a waffle slab used in a construction. The lifting equipment comprises a main body bracket, a sliding member and a plurality of clamping mechanisms. The main body bracket has a through hole in a center thereof. The sliding member is slidably disposed in the through hole of the main body bracket and is slidable between a first position and a second position. Each of the plurality of clamping mechanisms comprises a clamping member and a connecting rod. The clamping member comprises a first end and a second end, wherein the first end is pivotally connected to an outer edge of the main body bracket, and the second end is configured to extend into a hole of the waffle slab for clamping the waffle slab. A proximate end of the connecting rod is pivotally connected to a lower end of the sliding member, and a distal end of the connecting rod is pivotally connected to the clamping member between the first end and the second end.

Abstract: A sealing structure for the bottom of a beam space between precast panels, comprising: a first precast panel and a second precast panel substantially aligned to each other along a single plane and spaced from each other by a space, each of the first precast panel and the second precast panel defining an inner edge adjacent to the space; a soft pad abutting the space for sealing a bottom of the space; a plate abutting the soft pad; a fastening device securing a first side of the plate and a second side of the plate to the first precast panel and second precast panel, respectively, so as to assist the soft pad in the sealing of the bottom of the beam space; wherein the fastening device does not contact the soft pad.
