Atomic layer deposition apparatus and thin film forming method

An atomic layer deposition apparatus for forming a thin film on a substrate, comprising:

• a first container that defines a first inner space and includes a substrate carrying-in and carrying-out port and a gas introduction port in different positions, the substrate being carried in and out through the substrate carrying-in and carrying-out port, gas being introduced through the gas introduction port to form the thin film on the substrate;
• a second container that is formed into a canister shape and provided inside the first container to define a second inner space separated from the first inner space, the second container including a first opening;
• a pressing member that presses the second container in a longitudinal direction of the canister-shaped second container to separate the second inner space from the first inner space;
• a first moving mechanism that moves the second container in a predetermined direction;
• and
• a controller that controls the first moving mechanism such that the second container is moved to a first position where the substrate carrying-in and carrying-out port and the first opening are located opposite each other when the substrate is carried in and out, the controller controlling the first moving mechanism such that the second container is moved to a second position where the gas introduction port and the first opening are located opposite each other when the thin film is formed on the substrate.

An atomic layer deposition apparatus for forming a thin film on a substrate, comprising:

• a first container that defines a first inner space and includes a substrate carrying-in and carrying-out port and a gas introduction port in different positions, the first container is configured to be able to be separated into a lower portion including a bottom surface of the first container and an upper portion except the lower portion, the substrate being carried in and out through the substrate carrying-in and carrying-out port, gas being introduced through the gas introduction port to form the thin film on the substrate;
• a second container that is provided inside the first container to define a second inner space separated from the first inner space, the second container including a first opening;
• a first moving mechanism that moves the second container in a predetermined direction;
• a second moving mechanism that moves the lower portion so as to separate the lower portion from the upper portion;
• and
• a controller that controls the first moving mechanism such that the second container is moved to a first position where the substrate carrying-in and carrying-out port and the first opening are located opposite each other when the substrate is carried in and out, the controller controlling the first moving mechanism such that the second container is moved to a second position where the gas introduction port and the first opening are located opposite each other when the thin film is formed on the substrate, and the controller controlling the second moving mechanism such that the second container moves to a third position where the second container may be taken out to the outside when the second container is taken out to the outside of the first container.
