style="text-indent:25px">針對(duì)PVD制備薄膜應(yīng)力的解決辦法主要有：1.熱退火處理，薄膜中存在的各種缺陷是產(chǎn)生本征應(yīng)力的主要原因，這些缺陷一般都是非平衡缺陷，有自行消失的傾向，但需要外界給予活化能。對(duì)薄膜進(jìn)行熱處理，非平衡缺陷大量消失，薄膜內(nèi)應(yīng)力卓著降低；2.添加亞層控制多層薄膜應(yīng)力，利用應(yīng)變相消原理，在薄膜層之間再沉積一層薄膜，控制工藝使其呈現(xiàn)與結(jié)構(gòu)薄膜相反的應(yīng)力狀態(tài)，緩解應(yīng)力帶來的破壞作用，整體上抵消內(nèi)部應(yīng)力；3.提高襯底溫度，有利于薄膜和襯底間原子擴(kuò)散，并加速反應(yīng)過程，有利于形成擴(kuò)散附著，降低內(nèi)應(yīng)力。</p><p style="text-indent:25px">磁控濺射方向性要優(yōu)于電子束蒸發(fā)，但薄膜質(zhì)量，表面粗糙度等方面不如電子束蒸發(fā)。但磁控濺射可用于多種材料，適用性普遍，電子束蒸發(fā)則只能用于金屬材料蒸鍍，且高熔點(diǎn)金屬，如W，Mo等的蒸鍍較為困難。所以磁控濺射常用于新型氧化物，陶瓷材料的鍍膜，電子束則用于對(duì)薄膜質(zhì)量較高的金屬材料。LPCVD工藝在襯底表面淀積一層均勻的介質(zhì)薄膜，在微納加工當(dāng)中用于結(jié)構(gòu)層材料、xi牲層、絕緣層、掩模材料，LPCVD工藝淀積的材料有多晶硅、氮化硅、磷硅玻璃。不同的材料淀積采用不同的氣體。真空鍍膜流程：前處理及化學(xué)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。</p><div

style="text-indent:25px">PECVD在低溫范圍內(nèi)（200-350℃），沉積速率會(huì)隨著基片溫度的升高而略微下降，但不是太明顯。PECVD生長(zhǎng)氧化硅薄膜是一個(gè)比較復(fù)雜的過程，薄膜的沉積速率主要受到反應(yīng)氣體比例、RF功率、反應(yīng)室壓力、基片生長(zhǎng)溫度等。在一定范圍內(nèi)，提高硅烷與笑氣的比例，可提供氧化硅的沉積速率。在RF功率較低的時(shí)候，提升RF功率可提升薄膜的沉積速率，當(dāng)RF增加到一定值后，沉積速率隨RF增大而減少，然后趨于飽和。在一定的氣體總量條件下，沉積速率隨腔體壓力增大而增大。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)。吉林反射濺射真空鍍膜加工廠</p><p
