Abstract

The invention discloses a plasma body cleaning device, which mainly consists of a microwave system and a reaction device, wherein the microwave system comprises a microwave chamber, a microwave source and a microwave control circuit, the microwave source can be regulated and controlled through the microwave control circuit, and the regulation and the control on the density of the plasma body can be realized. The cleaning device effectively avoids the electrode pollution by adopting a microwave excitation mode, and simultaneously enlarges the pressure intensity work range. Because the microwave technology is mature, the microwave leakage can be easily controlled and protected, the cleaning device has good safety performance. The work pressure intensity can be controlled through regulating and controlling the flow speed of the cleaning reaction gas and the gas pumping speed of a vacuum device, the power of the microwave source can be controlled through the microwave control circuit, and the bombarding force on the surface of cleaning samples by the plasma body and the concentration of the plasma body can be effectively regulated. Thereby, the cleaning and the surface modification in different modes can be carried out according to the cleaning samples in different material types.

Description

Technical field [0001] The invention relates to a cleaning device, in particular to a plasma cleaning device. Background technique [0002] In the processing of optical devices and microelectronic components, surface cleaning technology has a very important position. At present, the widely used physical and chemical cleaning methods can be roughly divided into two types in terms of operation mode: wet cleaning and dry cleaning. Wet cleaning mainly relies on the effects of physical and chemical (solvents), such as the adsorption, soaking, dissolution and dispersion of chemical active agents, supplemented by physical methods such as ultrasonic, spray, rotation, boiling, steam and shaking to remove the surface of objects Stains. In the wet cleaning process, subsequent drying and wastewater treatment procedures are also required, and the labor protection and environmental pollution control costs are high. Dry cleaning mainly includes plasma cleaning technology, which mainly uses t...
