    • Substrate processing uniformity is improved in the surfaces of wafers and between the wafers. A substrate processing apparatus including: a substrate holder including a substrate stacking part configured to hold a plurality of vertically stacked substrates and a cylinder part disposed under the substrate stacking part to enclose a lower portion of the substrate holder; an inner tube configured to accommodate the substrate holder wherein a space between the cylinder part and a lower portion of the inner tube is smaller than a space between the substrate stacking part and an upper portion of the inner tube; an outer tube configured to enclose the inner tube with a gap therebetween; a gas nozzle installed in the inner tube; a gas injection hole disposed in the gas nozzle; a source gas supply unit configured to supply a source gas to an inside of the inner tube through the gas nozzle; a gas exhaust outlet disposed in a sidewall of the inner tube such that the inside of the inner tube communicates with the gap through the plurality of gas exhaust outlets; an exhaust unit configured to exhaust the gap so as to create a gas stream inside the inner tube in a direction from the gas injection hole to the plurality of gas exhaust outlets.
    • 晶片表面和晶片之间的基板加工均匀性得到改善。 一种基板处理装置,包括:基板保持器,其包括被配置为保持多个垂直堆叠的基板的基板堆叠部分和设置在所述基板堆叠部分下方以包围所述基板保持器的下部的圆筒部分; 内管,其构造成容纳所述基板保持器,其中所述筒部与所述内管的下部之间的间隔小于所述基板堆叠部与所述内管的上部之间的间隔; 外管,其构造成围绕内管间隙; 安装在内管中的气体喷嘴; 设置在所述气体喷嘴中的气体注入孔; 源气体供给单元,其构造成通过所述气体喷嘴将源气体供给到所述内管的内部; 排气出口,其设置在所述内管的侧壁中,使得所述内管的内部通过所述多个排气出口与所述间隙连通; 排气单元,其构造成排出所述间隙,以在从所述气体注入孔到所述多个排气出口的方向上在所述内管内产生气流。
