    • A gas injection unit allows uniform cooling thereof via smooth flow of coolant and can be easily manufactured. The gas injection unit for a chemical vapor deposition apparatus includes, inter alia: a gas distribution housing; a cooling housing positioned between the gas distribution housing and a processing chamber where a deposition process is performed, and formed with a coolant inlet through which coolant is introduced, and a coolant outlet through which the coolant is discharged; a processing gas pipe of which one end is opened to the gas distribution housing and the other end is opened to the processing chamber, the processing gas pipe penetrating the cooling housing; and a first wall part positioned inside the cooling housing such that an inside of the cooling housing is partitioned into a central path and a peripheral path, and formed with a penetration hole such that the central path communicates with the peripheral path.
    • 气体喷射单元允许通过冷却剂的平稳流动来均匀地冷却,并且可以容易地制造。 用于化学气相沉积装置的气体注入单元尤其包括:气体分配壳体; 定位在气体分配壳体和执行沉积过程的处理室之间并且形成有冷却剂引入的冷却剂入口的冷却壳体以及冷却剂通过其排出的冷却剂出口; 处理气体管道,其一端向气体分配壳体开口,另一端向处理室开口,处理气体管道穿透冷却壳体; 以及位于所述冷却壳体内部的第一壁部,使得所述冷却壳体的内部被分隔成中心路径和周边路径,并且形成有贯通孔,使得所述中心路径与所述周边路径连通。
