style="text-indent:25px">光刻（Photolithography)是一種圖形轉(zhuǎn)移的方法，在微納加工當(dāng)中不可或缺的技術(shù)。光刻是一個比較大的概念，其實它是有多步工序所組成的。1.清洗：清洗襯底表面的有機(jī)物。2.旋涂：將光刻膠旋涂在襯底表面。3.曝光。將光刻版與襯底對準(zhǔn)，在紫外光下曝光一定的時間。4.顯影：將曝光后的襯底在顯影液下顯影一定的時間，受過紫外線曝光的地方會溶解在顯影液當(dāng)中。5.后烘。將顯影后的襯底放置熱板上后烘，以增強光刻膠與襯底之前的粘附力。光刻是將掩模版上的圖形轉(zhuǎn)移到涂有光致抗蝕劑（或稱光刻膠）的襯底上，通過一系列生產(chǎn)步驟將硅片表面薄膜的特定部分除去的一種圖形轉(zhuǎn)移技術(shù)，云南接觸式光刻，云南接觸式光刻。光刻技術(shù)是借用照相技術(shù)，云南接觸式光刻、平板印刷技術(shù)的基礎(chǔ)上發(fā)展起來的半導(dǎo)體關(guān)鍵工藝技術(shù)。光刻技術(shù)是集成電路制造中利用光學(xué)-

style="text-indent:25px">光刻膠供應(yīng)商與客戶粘性大；一般情況下，為了保持光刻膠供應(yīng)和效果的穩(wěn)定，下游客戶與光刻膠供應(yīng)商一旦建立供應(yīng)關(guān)系后，不會輕易更換。通過建立反饋機(jī)制，滿足個性化需求，光刻膠供應(yīng)商與客戶的粘性不斷增加。后來者想要加入到供應(yīng)商行列，往往需要滿足比現(xiàn)有供應(yīng)商更高的要求。所以光刻膠行業(yè)對新進(jìn)入者壁壘較高。通常光刻膠等微電子化學(xué)品不僅品質(zhì)要求高，而且需要多種不同的品類滿足下游客戶多樣化的需。如果沒有規(guī)模效益，供應(yīng)商就無法承擔(dān)滿足***多樣化需求帶來的開銷。因此，品種規(guī)模構(gòu)成了進(jìn)入該行業(yè)的重要壁壘。低線寬光刻價格如今，全世界能夠生產(chǎn)光刻機(jī)的國家只有四個，中國成為了其中的一員。</p><div

style="text-indent:25px">光刻膠若性能不達(dá)標(biāo)會對芯片成品率造成重大影響。目前中國光刻膠國產(chǎn)化水平嚴(yán)重不足，重點技術(shù)差距在半導(dǎo)體光刻膠領(lǐng)域，有2-3代差距，隨著下游半導(dǎo)體行業(yè)、LED及平板顯示行業(yè)的快速發(fā)展，未來國內(nèi)光刻膠產(chǎn)品國產(chǎn)化替代空間巨大。同時，國內(nèi)光刻膠企業(yè)積極抓住中國晶圓制造擴(kuò)產(chǎn)的百年機(jī)遇，發(fā)展光刻膠業(yè)務(wù)，力爭早日追上國際先進(jìn)水平，打進(jìn)國內(nèi)新建晶圓廠的供應(yīng)鏈。光刻膠的國產(chǎn)化公關(guān)正在各方面展開，在面板屏顯光刻膠領(lǐng)域，中國已經(jīng)出現(xiàn)了一批有競爭力的本土企業(yè)。在半導(dǎo)體和面板光刻膠領(lǐng)域，盡管國產(chǎn)光刻膠距離國際先進(jìn)水平仍然有差距，但是在政策的支持和自身的不懈努力之下，中國已經(jīng)有一批光刻膠企業(yè)陸續(xù)實現(xiàn)了技術(shù)突破。廣東省科學(xué)院半導(dǎo)體研究所。</p><p style="text-indent:25px">每顆芯片誕生之初，都要經(jīng)過光刻機(jī)的雕刻，精度要達(dá)到頭發(fā)絲的千分之一，如今，全世界能夠生產(chǎn)光刻機(jī)的國家只有四個，中國成為了其中的一員，實現(xiàn)了從無到有的突破。光刻機(jī)又被稱為：掩模對準(zhǔn)曝光機(jī)、曝光系統(tǒng)、光刻系統(tǒng)等。常用的光刻機(jī)是掩模對準(zhǔn)光刻，所以它被稱為掩模對準(zhǔn)系統(tǒng)。它指的是通過將硅晶片表面上的膠整平，然后將掩模上的圖案轉(zhuǎn)移到光刻膠，將器件或電路結(jié)構(gòu)暫時“復(fù)制”到硅晶片上的過程。它不是簡單的激光器，但它的曝光系統(tǒng)基本上使用的是復(fù)雜的紫外光源。光刻機(jī)是芯片制造的中心設(shè)備之一，根據(jù)用途可分為幾類：光刻機(jī)生產(chǎn)芯片；有光刻機(jī)包裝；還有一款投影光刻機(jī)用在LED制造領(lǐng)域。光刻膠是由光引發(fā)劑（包括光增感劑、光致產(chǎn)酸劑）、光刻膠樹脂、單體、溶劑和其他助劑組成。</p><div

style="text-indent:25px">光刻膠行業(yè)具有極高的行業(yè)壁壘，因此在全球范圍其行業(yè)都呈現(xiàn)寡頭壟斷的局面。光刻膠行業(yè)長年被日本和美國專業(yè)公司壟斷。目前**大廠商就占據(jù)了全球光刻膠市場87%的份額，行業(yè)集中度高。并且高分辨率的KrF和ArF半導(dǎo)體光刻膠中心技術(shù)亦基本被日本和美國企業(yè)所壟斷，產(chǎn)品絕大多數(shù)出自日本和美國公司。整個光刻膠市場格局來看，日本是光刻膠行業(yè)的巨頭聚集地。目前中國大陸對于電子材料，特別是光刻膠方面對國外依賴較高。所以在半導(dǎo)體材料方面的國產(chǎn)代替是必然趨勢。云南接觸式光刻</p><p
