Abstract
A substrate processing apparatus processes a substrate having an upper side and a rear side. The substrate processing apparatus includes a substrate holder, a filler feeder, and a first cleaning liquid feeder. The substrate holder rotates the substrate while holding a central portion of the rear side of the substrate. The filler feeder feeds filler to the upper side of the substrate held by the substrate holder. The first cleaning liquid feeder feeds a cleaning liquid to the rear side of the substrate held by the substrate holder. The first cleaning liquid feeder feeds the cleaning liquid to an area, held by the substrate holder, of the rear side of the substrate.
