Abstract: A semiconductor structures and a method for forming the same are provided. The semiconductor structure includes first nanostructures and second nanostructures spaced apart from the first nanostructures in a first direction. A left-most point of the first nanostructures and a left-most point of the second nanostructures has a first distance in the first direction. The semiconductor structure further includes first source/drain features attached to opposite sides of the first nanostructures in a second direction being orthogonal to the first direction and third nanostructures and fourth nanostructures spaced apart from the third nanostructures in the first direction. A left-most point of the third nanostructures and a left-most point of the fourth nanostructures has a second distance in the first direction. In addition, the third nanostructures are wider than the first nanostructures in the first direction, and the first distance is smaller than the second distance.

Abstract: An organic compound pyrolysis flashover energy-saving regeneration treatment system for remaking organic waste such as family\industrial garbage, sewer mud, agricultural waste and livestock excreta etc. to become liquid and solid regenerated organic compounds by using a waste pre-treatment unit, an organic waste steaming sterilization unit, an organic waste pyrolysis flashover unit, a green energy generation & steam regeneration unit, a solid-liquid organic compound separation unit, a liquid organic compound regeneration unit and a solid organic compound regeneration unit, which compounds are used as organic fertilizer or feed for livestock farming, the system can effectively achieve the objects of recovering resources, purifying environment, saving energy and reducing carbon and regeneration of organic waste for reuse, it further can increase the efficiency of environmental conservation.
