style="text-indent:25px">磁控濺射的優(yōu)勢在于可根據(jù)靶材的性質(zhì)來選擇使用不同的靶qiang進(jìn)行濺射，靶qiang分為射頻靶(RF)、直流靶(DC)、直流脈沖靶(DC Pluse)。其中射頻靶主要用于導(dǎo)電性較差的氧化物、陶瓷等介質(zhì)膜的濺射，也可以進(jìn)行常規(guī)金屬材料濺射。直流靶只能用于導(dǎo)電性較好的金屬材料，而直流脈沖靶介于二者之間，可濺射硅、鍺等半導(dǎo)體材料。利用PECVD生長的氮化硅薄膜具有以下優(yōu)點(diǎn)：1.均勻性和重復(fù)性好，可大面積成膜2.可在低溫下成膜3.臺階覆蓋性比較好 4.薄膜成分和厚度容易控制 5.應(yīng)用范圍廣，設(shè)備簡單，易于產(chǎn)業(yè)化。在蒸發(fā)溫度以上進(jìn)行蒸發(fā)試，蒸發(fā)源溫度的微小變化即可引起蒸發(fā)速率發(fā)生很大變化。甘肅叉指電極真空鍍膜價(jià)錢</p><p
