style="text-indent:25px">電子束蒸發(fā)：將蒸發(fā)材料置于水冷坩堝中，利用電子束直接加熱使蒸發(fā)材料汽化并在襯底上凝結(jié)形成薄膜，是蒸度高熔點(diǎn)薄膜和高純薄膜的一種主要加熱方法。為了獲得性能良好的半導(dǎo)體電極Al膜，我們通過優(yōu)化工藝參數(shù)，制備了一系列性能優(yōu)越的Al薄膜。通過理論計(jì)算和性能測試，分析比較了電子束蒸發(fā)與磁控濺射兩種方法制備Al膜的特點(diǎn)。考慮Al膜的致密性就相當(dāng)于考慮Al膜的晶粒的大小，密度以及能達(dá)到均勻化的程度，因?yàn)樗仓苯佑绊慉l膜的其它性能，進(jìn)而影響半導(dǎo)體嘩啦的性能。氣相沉積的多晶Al膜的晶粒尺寸隨著沉積過程中吸附原子或原子團(tuán)在基片表面遷移率的增加而增加。由此可以看出Al膜的晶粒尺寸的大小將取決環(huán)于基片溫度、沉積速度、氣相原子在平行基片方面的速度分量、基片表面光潔度和化學(xué)活性等因素。</p><p style="text-indent:25px">常用的薄膜制備方式主要有兩種，其中一種是物理的氣相沉積（PVD），PVD的方法有磁控濺射鍍膜、電子束蒸發(fā)鍍膜、熱阻蒸發(fā)等。另一種是化學(xué)氣相沉積法（CVD），主要有常壓CVD、LPCVD（低壓氣相沉積法）、PECVD（等離子體增強(qiáng)氣相沉積法）等方法。解決靶中毒主要有以下幾種方法;1.使用射頻電源進(jìn)行濺射；2.采用閉環(huán)控制反應(yīng)氣體通入流量；3.使用孿生靶交替濺射；4.控制鍍膜模式的變換：在鍍膜前，采集靶中毒的遲滯效應(yīng)曲線，使進(jìn)氣流量控制在產(chǎn)生靶中毒的前沿，確保工藝過程始終處于沉積速率陡降前的模式。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。</p><div

style="text-indent:25px">PECVD系統(tǒng)的氣源幾乎都是由氣體鋼瓶供氣，這些鋼瓶被放置在有許多安全保護(hù)裝置的氣柜中，通過氣柜上的控制面板、管道輸送到PECVD的工藝腔體中。在淀積時(shí)，反應(yīng)氣體的多少會(huì)影響淀積的速率及其均勻性等，因此需要嚴(yán)格控制氣體流量，通常采用質(zhì)量流量計(jì)來實(shí)現(xiàn)精確控制。PECVD一般用到的氣體有硅烷、笑氣、氨氣等其他。這些氣體通過氣管進(jìn)入在反應(yīng)腔體，在射頻源的左右下，氣體被電離成活性基團(tuán)。活性基團(tuán)進(jìn)行化學(xué)反應(yīng)，在低溫（300攝氏度左右）生長氧化硅或者氮化硅。氧化硅和氮化硅可用于半導(dǎo)體器件的絕緣層，可有效的進(jìn)行絕緣。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。上海真空鍍膜加工廠</p><p
