    • A chemical vapor deposition apparatus has a vacuum processing chamber, a susceptor for holding a plurality of substrates each placed with a film deposition surface thereof facing downward; a heater disposed above the susceptor; a first barrier gas supply port for supplying a barrier gas to the upper surface of the susceptor; and a second barrier gas supply port for supplying the barrier gas to the upper surface of the heater. The barrier gas supplied from the first barrier gas supply port and the barrier gas supplied from the second barrier gas supply port have their flow rates controlled independently. By properly setting the ratio between the amount of the barrier gas supplied from the first barrier gas supply port and the amount of the barrier gas supplied from the second barrier gas supply port and the ratio between the amount of the barrier gas supplied and the amount of a raw material gas supplied, it becomes possible to form a film which is reduced in the number of particles adhered thereto.
    • 化学气相沉积装置具有真空处理室,用于保持多个基板的基座,每个基板的薄膜沉积表面面向下放置; 设置在基座上方的加热器; 用于向所述基座的上表面供给阻挡气体的第一阻挡气体供给口; 以及用于将阻挡气体供给到加热器的上表面的第二阻挡气体供给口。 从第一势垒气体供给口供给的阻挡气体和从第二势垒气体供给口供给的势垒气体,其流量独立地被控制。 通过适当地设定从第一势垒气体供给口供给的阻挡气体的量与从第二阻挡气体供给口供给的阻挡气体的量之间的比例与供给的阻隔气体的量之间的比例, 提供原料气体,可以形成减少附着于其上的颗粒数量的膜。
