    • Provided are a gas supplying apparatus and an equipment for etching a substrate edge having the same. The gas supplying apparatus for supplying a gas to a chamber having a reaction compartment includes: a gas spraying unit for spraying gas to the reaction compartment; a gas storage unit for storing the gas; first and second extension passages provided between the gas spraying unit and the gas storage unit; and a leakage preventing unit provided to a connection region of the first and second extension passages to prevent leakage of the gas. The passage through which a gas is provided to the reaction compartment of the chamber is positioned inside the lateral wall of the chamber to prevent damage thereof, and leakage of the gas resulting therefrom can be prevented. An exhaust unit capable of exhausting a toxic gas to the outside is provided on one side of a passage connection portion connecting the passages in case the toxic gas leaks and, therefore, leakage of the toxic gas can be prevented.
    • 提供一种用于蚀刻具有该气体供给装置的基板边缘的气体供给装置和设备。 用于向具有反应室的室供给气体的气体供给装置包括:气体喷射单元,用于将气体喷射到反应室; 用于存储气体的气体存储单元; 设置在气体喷射单元和气体存储单元之间的第一和第二延伸通道; 以及设置在第一和第二延伸通道的连接区域以防止气体泄漏的防漏单元。 将气体设置到室的反应室的通道位于室的侧壁的内侧,以防止其损坏,并且可以防止由其产生的气体的泄漏。 在有毒气体泄漏的情况下,能够将有毒气体排出到外部的排气单元设置在连接通路的通路连接部的一侧,因此能够防止有毒气体的泄漏。
