Abstract: A semiconductor device is provided. The semiconductor device includes a substrate, a stacked gate structure, and a wall structure. The stacked gate structure is on the substrate and extending along a first direction. The wall structure is on the substrate and laterally aside the stacked gate structure. The wall structure extends along the first direction and a second direction perpendicular to the first direction. The stacked gate structure is overlapped with the wall structure in the first direction and the second direction.

Abstract: A vertical curtain cutter includes at least a base and a mold cutting device fixed on the base, which consists of a clamper, a knife and a motor. The clamper has a stationary clamp block and a movable clamp block, and the stationary clamp block has a flat clamp surface at one side and a curved clamp surface at other side. As a result, the movable clamp block and the stationary clamp block can clamp between them the rolled curtain cloth or folded-up curtain cloth. The cloth is vertically inserted by reversing the flat surface and the curved surface of the stationary clamp block. The motor can drive the knife to shift towards the curtain cloth and cut it, so that the cutter is able to cut either rolled or folded-up curtain cloth into multiple curtain pieces.

Abstract: A blind cutter includes at least a worktable, a drive device, and a number of knife modules. The drive device has a speed-reducing motor for rotating a rotary shaft, and a number of gears fixed on the rotary shaft to engage and move a number of racks. The knife modules respectively have a module base arranged lengthwise on the work table, having a special hole for special blinds to pass through, with a knife fitted in slidably and respectively moved by the racks for cutting a blind material respectively extending on the module bases.

The clamper has a stationary clamp block and a movable clamp block, and the stationary clamp block has a flat clamp surface at one side and a curved clamp surface at other side. Then the movable clamp block and the stationary clamp block can clamp between them roll curtain cloth or folded-up curtain cloth vertically inserted by reversing the flat surface and the curved surface of the stationary clamp block. The motor can drive the knife shift toward the curtain cloth and cut it with a molding way, so the cutter is able to cut either roll or folded-up curtain cloth into many curtain pieces.
