  • Substrate cleaning equipment, substrate treatment system including the same, and method of fabricating semiconductor device using the substrate cleaning equipment
    Patent number: 11791173
    Abstract: Substrate cleaning equipment includes a substrate holder which supports a substrate, a swing body, a head, a first cleaning liquid supply structure, and a second cleaning liquid supply structure. The swing body moves along a sweep line on a main surface of the substrate. The head is coupled to the swing body and includes a pad attachment surface facing the substrate holder. The first cleaning liquid supply structure is coupled to the swing body and sprays a first cleaning liquid onto the main surface of the substrate. The second cleaning liquid supply structure sprays a second cleaning liquid onto the main surface of the substrate. A buffing pad is attached to the pad attachment surface.
