PECVD工作原理是什么？PECVD技術(shù)是在低氣壓下，利用低bai溫等離子體在工藝腔體的陰極du上（即zhi樣品放置的托盤）產(chǎn)生輝光放電，利用輝光放電（或另加發(fā)熱體）使樣品升溫到預(yù)定的溫度，然后通入適量的工藝氣體，這些氣體經(jīng)一系列化學(xué)反應(yīng)和等離子體反應(yīng)，較終在樣品表面形成固態(tài)薄膜。其工藝原理示意圖如圖1所示。在反應(yīng)過程中，反應(yīng)氣體從進(jìn)氣口進(jìn)入爐腔，逐漸擴(kuò)散至樣品表面，在射頻源激發(fā)的電場(chǎng)作用下，反應(yīng)氣體分解成電子、離子和活性基團(tuán)等。這些分解物發(fā)生化學(xué)反應(yīng)，生成形成膜的初始成分和副反應(yīng)物，這些生成物以化學(xué)鍵的形式吸附到樣品表面，生成固態(tài)膜的晶核，晶核逐漸生長(zhǎng)成島狀物，島狀物繼續(xù)生長(zhǎng)成連續(xù)的薄膜。在薄膜生長(zhǎng)過程中，各種副產(chǎn)物從膜的表面逐漸脫離，在真空泵的作用下從出口排出。廣州立式爐高校**真空箱式爐系列陶瓷纖維爐襯熱處理爐引進(jìn)國(guó)外先進(jìn)技術(shù)、秉承歐洲工業(yè)爐高性能、自動(dòng)化程度高。</p><div

1、爐子初次使用或長(zhǎng)時(shí)間不用后，要在120℃左右烘烤1小時(shí)，在300℃左右烘烤2小時(shí)后使用，以免造成爐膛開裂。爐溫盡量不要超過額定溫度，以免損壞加熱元件及爐襯。禁止向爐膛內(nèi)直接灌注各種液體及溶解金屬，保持爐內(nèi)的清潔。 2、產(chǎn)生失透缺陷屬于正常現(xiàn)象爐膛若采用石英管，當(dāng)溫度高于1000℃時(shí)，石英管的高溫部分會(huì)出現(xiàn)不透明現(xiàn)象，這叫失透(又叫析晶性)是連熔石英管的個(gè)固有缺陷，屬正?，F(xiàn)象。 3、冷爐使用時(shí)，低溫段升溫速率不易過快冷爐使用時(shí)，由于爐膛是冷的，須大量吸熱，所以低溫段升溫速率不易過快，各溫度段的升溫速率差別不易太大，設(shè)置升溫速率時(shí)應(yīng)充分考慮所燒結(jié)材料的物理化學(xué)性質(zhì)，以免出現(xiàn)噴料現(xiàn)象，污染爐管。電爐對(duì)溫度的調(diào)節(jié)不需過快，應(yīng)逐檔調(diào)節(jié)，以免電流過大燒壞碳棒及其它電氣器件。</p><div
