  • Publication number: 20250218729
    Abstract: Proposed are a shower head assembly and a substrate processing apparatus including the same. The shower head assembly includes a shower head for discharging a process gas into a substrate processing space of a process chamber, and a blocking airflow forming unit configured to block discharge of the process gas by forming a blocking airflow within the shower head, which passes through the inside of the shower head in a direction perpendicular to a discharge direction of the process gas. According to the shower head assembly, the amount of process gas supplied to the substrate processing space may be precisely controlled.

  • Patent number: 12146710
    Abstract: A substrate treating apparatus and a substrate treating system including the same are disclosed, in which the number of heat treatment chambers such as anneal chambers may be varied. The substrate treating apparatus includes a first chamber heat-treating a substrate; and a second chamber treating the substrate in another way different from heat-treatment, wherein the number of the first chambers is varied depending on the number of the second chambers that need heat treatment for the substrate.

  • Publication number: 20220084829
    Abstract: A method of fabricating a semiconductor device with improved electrical characteristics and reliability is provided. The method of fabricating the semiconductor device includes providing a substrate, in which a first oxide film, a nitride film, and a second oxide film are sequentially stacked, and a trench penetrating the first oxide film, the nitride film, and the second oxide film is formed, chamfering the oxide film exposed by the trench while removing a part of the nitride film exposed by the trench by using a first plasma process, and removing the nitride film left after the first plasma process by using a second plasma process.
