    • A photo CVD apparatus includes a reaction chamber, a vacuum pump, and a light source chamber disposed in the reaction chamber, the light source chamber having a light window. A light source is provided in the light source chamber for irradiating the inside of the reaction chamber through the window. A device inputs reactive gas into the reaction chamber, and an electrode is disposed in the reaction space adjacent to the window and located between the substrate and the window. A method of depositing a layer on a substrate includes the steps of disposing a substrate in a reaction chamber, introducing a reactive gas, and initiating a photo-chemical reaction to deposit the product of the reaction on the substrate by irradiating the reactive gas with light emitted from a light source through a window of a light source chamber in which the light source is disposed. The substrate is then removed from the reaction chamber, and an etchant gas is introduced into the reaction chamber. A voltage is then applied between the substrate holder and an electrode which is located between the window and the substrate holder for carrying out plasma etching of the window.
    • 光CVD装置包括反应室,真空泵和设置在反应室中的光源室,光源室具有光窗。 光源设置在光源室中,用于通过窗口照射反应室的内部。 装置将反应性气体输入到反应室中,并且电极设置在与窗口相邻的反应空间中并且位于基板和窗之间。 在衬底上沉积层的方法包括以下步骤:在反应室中设置衬底,引入反应气体,并引发光化学反应,以通过用光照射反应气体将反应产物沉积在衬底上 从光源通过其中设置有光源的光源室的窗口发射。 然后将基底从反应室中取出,并将蚀刻剂气体引入反应室。 然后在衬底保持器和位于窗口和衬底保持器之间的电极之间施加电压以进行窗口的等离子体蚀刻。
