style="text-indent:25px">針對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。江蘇ITO鍍膜真空鍍膜多少錢</p><p
