| This invention provides an aerosol deposition equipment, which comprises a chamber, a plasma device and a spray device. Said chamber defines a processing space and includes a carrier which is set in said processing space and has a carrying surface. Said spray device is used to generate aerosol and send said aerosol into said processing space, and includes an injection unit, an atomization unit and a valve unit. Said valve unit is connected with said chamber, and is used to control said aerosol to enter said processing space. Said valve unit defines a straight channel for said aerosol to pass through and has a contact surface which connected to said chamber. A value of a width of said carrying surface divided by a distance between said carrying surface and said contact surface is greater than 0.05 and less than 3. An angle between a normal direction of said carrying surface and said contact surface is 45 degrees to 135 degrees. A value of a length of said straight channel divided by a minimum equivalent diameter of said straight channel is greater than 0.125 and less than 15. |
