[转帖]离子束辅助镀膜
请教离子束辅助镀膜的原理? <P>e-beam assistant deposition is a method, e-beam bombards the taget, which makes the taget evaporating high energy particles,it will induce deposition film more stable. while plasma generates by electric field or magenetic field.e-beam and plasma are two different methods. i think so.</P> 离子束轰击表面,可以增加基底的表面能,从而改善膜的结构(更致密),提高附着力;根据所用离子的不同,还可已改善膜的成份。总之好处多多。 sorry, i just make a mistake, iron assisted deposition, not e-beam, irom beam (it also could be called plasma), Mr fulong927's explain is very good <P>没有离子源镀膜时,由于分子能量较底,当分子接触到基板时失去能量,并阻挡后面分子的前进。从而形成柱状结构。膜层中会有大量间隙存在,在高温或高湿下光谱会偏移。</P><P>有离子源镀膜时,高能离子携带分子,轰击表面,从而改善膜的结构(更致密),提高附着力,提高光谱稳定性。</P> 谢谢!!!!!<img src="http://bbs.oecr.com/Skins/default/topicface/face1.gif">
