    • Embodiments for an apparatus and method for depositing one or more layers onto a substrate or a freestanding shape inside a reaction chamber operating at a temperature of at least 700° C. and 10 torr are provided. The apparatus is provided with means for defining a volume space in the reaction chamber for pre-reacting the reactant feeds forming at least a reaction precursor in a gaseous form, and a volume space for depositing a coating layer of uniform thickness on the substrate from the reacted precursor. In one embodiment, the means for defining the two different zones comprises a distribution medium separating the pre-reaction zone from the deposition zone, for uniform distribution of the reacted precursor on the substrate. In another embodiment, the means for defining the two different zones comprises a plurality of reactant feed jets or injectors, for creating a jet-interaction zone or pre-reactant zone separate from a deposition zone, for deposing the reacted precursor on the substrate.
    • 提供了用于在至少700℃和10托的温度下操作的反应室内将一个或多个层沉积到基底或独立形状上的装置和方法的实施例。 该装置设置有用于限定反应室中的体积空间的装置,用于使至少形成气态反应前体的反应物进料预反应,以及用于在基板上沉积具有均匀厚度的涂层的体积空间 反应前体。 在一个实施方案中,用于限定两个不同区域的装置包括将预反应区域与沉积区域分离的分配介质,用于将反应的前体均匀分布在基底上。 在另一个实施方案中,用于限定两个不同区域的装置包括多个反应物进料射流或喷射器,用于产生与沉积区分离的喷射相互作用区域或预反应物区域,用于使基底上的反应前体脱落。
