Title:
ATOMIC LAYER DEPOSITION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/000372
Kind Code:
A1
Abstract:
An atomic layer deposition device and method. The atomic layer deposition device comprises: a bearing assembly, which comprises a reaction cavity (130) used for accommodating powder to be used for coating; a first spray head (200), wherein the first spray head (200) is located below the reaction cavity (130), and the first spray head (200) comprises a plurality of downward spray-in channels provided in a first direction and downward discharge channels provided between adjacent downward spray-in channels, the downward spray-in channels being used for spraying a gas to the reaction cavity (130), and the downward discharge channels being used for discharging excess gas in the reaction cavity (130); a gas source assembly (500), wherein the gas source assembly (500) is connected to the first spray head (200), the gas source assembly (500) is used for supplying the gas to the various downward spray-in channels, and in the first direction, in the adjacent downward spray-in channels, the gas introduced into one of the downward spray-in channels is a carrier gas; and a driving assembly, which is used for driving the powder to be used for coating to move in the first direction.
