3、]2223/23矩形平面移動(dòng)濺射靶的設(shè)計(jì)矩形平面移動(dòng)濺射靶的設(shè)計(jì)摘要:本文介紹了一種真空磁控鍍膜系統(tǒng)的移動(dòng)陰極靶。磁控濺射鍍膜現(xiàn)在已經(jīng)成為工業(yè)鍍膜生產(chǎn)中最主要的技術(shù)之一,它能有效降低靶室的工作壓強(qiáng)和靶的工作電壓,提高濺射速率和沉積速率,降低基片溫度,減小等離子體對(duì)膜層的破壞,特別適合于大面積鍍膜生產(chǎn)。但靶面的非均勻剝蝕會(huì)降低靶材的利用率,造成濺射過(guò)程中參數(shù)的變化,嚴(yán)重影響濺射過(guò)程的穩(wěn)定性。磁控濺射鍍膜中靶的特性直接與濺射穩(wěn)定性和膜層特性相關(guān),因此如何優(yōu)化設(shè)計(jì)靶,增加靶材利用率成為工業(yè)鍍膜生產(chǎn)中迫切需要解決的問(wèn)題。在這次設(shè)計(jì)中,我運(yùn)用一
