style="text-indent:25px">磁控濺射主要利用輝光放電(glowdischarge)將氬氣(Ar)離子撞擊靶材(target)表面,靶材的原子被彈出而堆積在基板表面形成薄膜。濺鍍薄膜的性質(zhì)、均勻度都比蒸鍍薄膜來的好,但是鍍膜速度卻比蒸鍍慢比較多。新型的濺鍍?cè)O(shè)備幾乎都使用強(qiáng)力磁鐵將電子成螺旋狀運(yùn)動(dòng)以加速靶材周圍的氬氣離子化,造成靶與氬氣離子間的撞擊機(jī)率增加,提高濺鍍速率。真空鍍膜的物理過程：PVD（物理的氣相沉積技術(shù)）的基本原理可分為三個(gè)工藝步驟：（1）金屬顆粒的氣化：即鍍料的蒸發(fā)、升華或被濺射從而形成氣化源（2）鍍料粒子（（原子、分子或離子）的遷移：由氣化源供出原子、分子或離子經(jīng)過碰撞，產(chǎn)生多種反應(yīng)。（3）鍍料粒子在基片表面的沉積。</p><p style="text-indent:25px">PECVD，等離子體化學(xué)氣相沉積法是借助微波或射頻等使含有薄膜組成原子的氣體電離，使局部形成等離子體，而等離子體化學(xué)活性很強(qiáng)，兩種或多種氣體很容易發(fā)生反應(yīng)，在襯底上沉積出所期待的薄膜。為了使化學(xué)反應(yīng)能在較低的溫度下進(jìn)行，利用了等離子體的活性來促進(jìn)反應(yīng)，因此，這種CVD稱為等離子體增強(qiáng)化學(xué)氣相沉積。真空鍍膜的工藝流程：真空鍍膜的工藝流程一般依次為：前處理及化學(xué)清洗（材料進(jìn)行有機(jī)清洗和無機(jī)清洗）→襯底真空中烘烤加熱→等離子體清洗→金屬離子轟擊→鍍金屬過渡層→鍍膜（通入反應(yīng)氣體）。磁控濺射常用來沉積TSV結(jié)構(gòu)的阻擋層和種子層，通過對(duì)相關(guān)參數(shù)的調(diào)整和引入負(fù)偏壓。</p><div
