Abstract: A semiconductor device includes a substrate including a first region, and a second region, a first gate structure and a second gate structure on the substrate of the first region, a third gate structure and a fourth gate structure on the substrate of the second region, a first interlayer insulating film on the substrate of the first region and including a first lower interlayer insulating film and a first upper interlayer insulating film, a second interlayer insulating film on the substrate of the second region and including a second lower interlayer insulating film and a second upper interlayer insulating film, a first contact between the first gate structure and the second gate structure and within the first interlayer insulating film, and a second contact formed between the third gate structure and the fourth gate structure and within the second interlayer insulating film.

Abstract: Disclosed is an apparatus for purifying asbestos-contaminated soil capable of increasing the removable efficiency of removing the soil by applying a drop method, facilitating the scattering of asbestos by extending the drop time of soil, and improving the separation efficiency of the asbestos from the contaminated soil by preventing the generation of eddies in the soil. The apparatus includes a blowing unit 100 including a blowing case 110 provided with a vertical portion 111 and horizontal portions 112 and blowers 120; a drop unit 200 including a drop case 210, a storage hopper 220, a discharge device 230, shock absorbing plates 240, and guide plates 250; a transfer unit 300 including a plurality of transfer cases 310 and screens 320; and a discharge unit 400 having a third opening 401 and a vent hole 402.
