硅片硅料清洗机的机理,主要是依靠等离子体中活性粒子的“活化作用”达到去除物体表面污渍的目的。就反应机理来看,等离子体清洗通常包括以下过程:无机气体被激发为等离子态;气相物质被吸附在固体表面;被吸附基团与固体表面分子反应生成产物分子;产物分子解析形成气相;反应残余物脱离表面。
The mechanism of silicon wafer cleaning machine mainly relies on the "activation" of active particles in plasma to remove stains on the surface of objects. In terms of reaction mechanism, plasma cleaning usually includes the following processes: inorganic gas is excited into plasma state; Gaseous substances are adsorbed on the solid surface; The adsorbed group reacts with the solid surface molecules to produce product molecules; The product molecules are resolved to form gas phase; The reaction residue is separated from the surface.
The manufacturer of ultrasonic cleaning machine reminds that there are three methods for silicon wafer and silicon material cleaning machine:
①刷洗或擦洗:可除去颗粒污染和大多数粘在片子上的薄膜。
① Brushing or scrubbing: it can remove particle pollution and most of the films stuck on the film.
②高压清洗:是用液体喷射片子表面,喷嘴的压力高达几百个大气压。高压清洗靠喷射作用,片子不易产生划痕和损伤。但高压喷射会产生静电作用,靠调节喷嘴到片子的距离、角度或加入防静电剂加以避免。
② High pressure cleaning: liquid is used to spray the surface of the sheet, and the pressure of the nozzle is as high as hundreds of atmospheres. High pressure cleaning relies on spray, so the film is not easy to produce scratches and damage. However, high-pressure spray will produce electrostatic effect, which can be avoided by adjusting the distance and angle between the nozzle and the film or adding antistatic agent.
③超声波清洗:超声波声能传入溶液,靠气蚀作用洗掉片子上的污染。但是,从有图形的片子上除去小于1微米颗粒则比较困难。将频率提高到超高频频段,清洗效果更好。
③ Ultrasonic cleaning: ultrasonic energy is transferred into the solution, and the pollution on the film is washed away by cavitation. However, it is difficult to remove particles smaller than 1 micron from the patterned film. The cleaning effect is better when the frequency is increased to ultra-high frequency band.
