摘要:
A method and apparatus for generating gas for a processing system is provided. In one embodiment, an apparatus for generating gas for a processing system includes a canister having at least one baffle disposed between two ports and containing a precursor material. The precursor material is adapted to produce a gas vapor when heated to a defined temperature at a defined pressure. The baffle forces a carrier gas to travel an extended mean path between the inlet and outlet ports. In another embodiment, an apparatus for generating gas includes a canister having a tube that directs a carrier gas flowing into the canister away from a precursor material disposed within the canister.
摘要(中):
提供了一种用于为处理系统产生气体的方法和装置。 在一个实施例中,用于为处理系统产生气体的装置包括罐,所述罐具有设置在两个端口之间并包含前体材料的至少一个挡板。 当在限定的压力下加热到限定的温度时,前体材料适于产生气体蒸汽。 挡板迫使载气在入口和出口之间延伸平均路径。 在另一个实施例中,用于产生气体的装置包括具有管的罐,该管将流入罐中的载气引导离开布置在罐内的前体材料。
