Abstract
Disclosed is a ceramic air inlet radio frequency connection type cleaning device, comprising an etching system, a cleaning system, a power supply control device and a radio frequency cleaning mechanism, wherein the power supply control device is connected to the etching system and the cleaning system and is used for power supply switching; the etching system is connected to two single three-dimensional coil bodies of a three-dimensional coil by means of two lines of a power distribution box so as to etch a wafer in a chamber; and the cleaning system enables the lower surface of a top ceramic air inlet nozzle connected to the radio frequency cleaning mechanism to generate high negative pressure by connecting a radio frequency to the radio frequency cleaning mechanism, such that plasmas directly bombard the lower surface of the top ceramic air inlet nozzle.
