摘要:
A thermal processing apparatus has a discharger for discharging process gas from a processing chamber and a ceiling plate provided between the substrate and the discharger. The ceiling plate has apertures at different aperture ratios in accordance with distances from the center of the ceiling plate. The apparatus may have dischargers provided over concentric circles of the substrate and adjusters for adjusting a discharging amount of the corresponding discharger. The apparatus may have gas suppliers provided over the concentric circles of the substrate and adjusters each for adjusting a supply amount of the corresponding supplier.
