    • PURPOSE: To use gas supplied into a reaction tube efficiently by improving the shape of a gas nozzle. CONSTITUTION: A tubular reaction tube 12 is installed vertically and the opening on a end flange 13 is sealed hermetically with a seal cap 14 and then a boat 15 mounting substrates, i.e., wafers W, in multistage is inserted into the reaction tube 12. Subsequently, gas is supplied from a nozzle 21 to the plurality of wafers W in the reaction tube 12 thus depositing a thin film on the wafers W. The nozzle 21 is provided to creep along the inner wall 22 of the reaction tube 12 in the axial direction thereof. The nozzle 21 has an inner space 23 spreading over an angle of 45°-180° in the inner circumferential direction of the tube. The nozzle 21 is provided with a plurality of gas ejection openings 24 in correspondence with respective wafers W and supplies gas above respective wafers W.
    • 目的:通过改善气体喷嘴的形状,有效地使用供应到反应管中的气体。 构成:管状反应管12垂直安装,端部凸缘13上的开口与密封盖14密封地密封,然后将安装基板(即,多层的晶片W)的舟形管15插入反应管12中。随后 从喷嘴21向反应管12中的多个晶片W供给气体,从而在晶片W上沉积薄膜。喷嘴21沿着轴向沿反应管12的内壁22蠕变 它们。 喷嘴21具有在管的内周方向上以45°-180°的角度扩展的内部空间23。 喷嘴21设置有与各个晶片W对应的多个气体喷射开口24,并且在各个晶片W上提供气体。
