style="text-indent:25px">電子束蒸發(fā)法是真空蒸發(fā)鍍膜中常用的一種方法，是在高真空條件下利用電子束進(jìn)行直接加熱蒸發(fā)材料，使蒸發(fā)材料氣化并向襯底輸運(yùn)，在基底上凝結(jié)形成薄膜的方法。在電子束加熱裝置中，被加熱的材料放置于水冷的坩堝當(dāng)中，可避免蒸發(fā)材料與坩堝壁發(fā)生反應(yīng)影響薄膜的質(zhì)量，因此，電子束蒸發(fā)沉積法可以制備高純薄膜。LPCVD反應(yīng)的能量源是熱能，通常其溫度在500℃-1000℃之間，壓力在0.1Torr-2Torr以內(nèi)，影響其沉積反應(yīng)的主要參數(shù)是溫度、壓力和氣體流量，它的主要特征是因?yàn)樵诘蛪涵h(huán)境下，反應(yīng)氣體的平均自由程及擴(kuò)散系數(shù)變大，膜厚均勻性好、臺(tái)階覆蓋性好。目前采用LPCVD工藝制作的主要材料有：多晶硅、單晶硅、非晶硅、氮化硅等。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。佛山功率器件真空鍍膜加工平臺(tái)</p><p style="text-indent:25px">在鍍膜過程中，想要控制蒸發(fā)速率，必須精確控制蒸發(fā)源的溫度，加熱時(shí)應(yīng)盡量避免產(chǎn)生過大的溫度梯度。北京等離子體增強(qiáng)氣相沉積真空鍍膜服務(wù)</p><p style="text-indent:25px">PECVD工藝中由于等離子體中高速運(yùn)動(dòng)的電子撞擊到中性的反應(yīng)氣體分子，就會(huì)使中性反應(yīng)氣體分子變成碎片或處于活動(dòng)的狀態(tài)容易發(fā)生反應(yīng)，以在襯底在300-350℃就可以得到良好的氧化硅或者氮化硅薄膜，可以在器件當(dāng)中作為鈍化絕緣層，來提高器件的可靠性。等離子體化學(xué)氣相沉積法，利用了等離子體的活性來促進(jìn)反應(yīng)，使化學(xué)反應(yīng)能在較低的溫度下進(jìn)行。優(yōu)點(diǎn)是：反應(yīng)溫度降低，沉積速率較快，成膜質(zhì)量好，不容易破裂。缺點(diǎn)是：設(shè)備投資大、對(duì)氣管有特殊要求。北京等離子體增強(qiáng)氣相沉積真空鍍膜服務(wù)</p><p
