style="text-indent:25px">半導(dǎo)體檢測是產(chǎn)品良率和成本管理的重要環(huán)節(jié)，在半導(dǎo)體制造過程有著舉足輕重的地位。面臨降低測試成本和提高產(chǎn)品良率的壓力，測試環(huán)節(jié)將在產(chǎn)業(yè)鏈中占據(jù)更為重要的地位。摩爾定律預(yù)測，芯片上的元器件數(shù)目每隔18個(gè)月會增加一倍，單位元器件的材料成本和制造成本會成倍降低，但芯片的復(fù)雜化將使測試成本不斷增加。根據(jù)ITRS的數(shù)據(jù)，單位晶體管的測試成本在2012年前后與制造成本持平，并在2014年之后完成超越，占據(jù)芯片總成本的35-55%。另外，隨著芯片制程不斷突破物理極限，集成度也越來越高，測試環(huán)節(jié)對產(chǎn)品良率的監(jiān)控將會愈發(fā)重要。上海半導(dǎo)體設(shè)備廠家推薦半導(dǎo)體檢測設(shè)備：使用電子束檢測對缺陷進(jìn)行精確掃描成像，兩種技術(shù)的結(jié)合使用可以提高量檢測的效率。</p><div

style="text-indent:25px">半導(dǎo)體檢測設(shè)備：測試設(shè)備需求旺盛，國內(nèi)公司已有一定技術(shù)積累。從2017年開始，國內(nèi)存儲器和邏輯芯片產(chǎn)能不斷釋放，目前在建和擬建晶圓廠項(xiàng)目總投資金額接近萬億元規(guī)模。根據(jù)SEMI估算，2018-2020年國內(nèi)半導(dǎo)體制造設(shè)備投資額約為1550、1604、1702億元，按照歷史經(jīng)驗(yàn)檢測設(shè)備占總設(shè)備17%（晶圓檢測9%，過程工藝控制8%）的比例進(jìn)行測算，2018-2020年國內(nèi)晶圓廠檢測對應(yīng)的半導(dǎo)體檢測設(shè)備需求分別為264、273、289億元，行業(yè)研究敬請閱讀末頁的重要說明Page4隨著測試成本占比逐年升高，實(shí)際需求有望在此基礎(chǔ)上繼續(xù)突破。國內(nèi)檢測設(shè)備公司方面，長川科技、北京華峰技術(shù)水平較為優(yōu)先，長川科技生產(chǎn)的測試機(jī)、分選機(jī)已獲得長電科技、華天科技等多個(gè)封測、代工廠商的使用和認(rèn)可，在國內(nèi)實(shí)現(xiàn)批量銷售。</p><p style="text-indent:25px">半導(dǎo)體檢測設(shè)備：膜應(yīng)力量測：在襯底表面上沉積多層薄膜可能會引入強(qiáng)的局部力量，這種局部力量被稱之為膜應(yīng)力。膜應(yīng)力可能會導(dǎo)致襯底發(fā)生形變，進(jìn)而影響器件的穩(wěn)定性。產(chǎn)線上一般通過分析由于薄膜淀積造成的襯底曲率半徑變化來進(jìn)行膜應(yīng)力測試，此種技術(shù)可用于包括金屬、介質(zhì)和聚合物在內(nèi)的各種標(biāo)準(zhǔn)薄膜。進(jìn)行薄膜應(yīng)力測試時(shí)經(jīng)常使用的技術(shù)有電子掃描顯微鏡、原子力顯微鏡。摻雜濃度量測：離子注入是半導(dǎo)體摻雜工藝中一種重要的技術(shù)，通過在硅片的一些區(qū)域內(nèi)注入不同種類的離子，可以使不同區(qū)域硅片具有不同的電性能。工藝中使用的雜質(zhì)濃度通常介于1010個(gè)粒子/cm3到1018個(gè)粒子/cm3之間，雜質(zhì)粒子的濃度和分布會對半導(dǎo)體的性能產(chǎn)生重要影響。由于雜質(zhì)粒子造成的晶格缺陷會改變硅片表面的光線反射率，根據(jù)此原理便可計(jì)算出雜質(zhì)濃度。目前普遍應(yīng)用于測量雜質(zhì)濃度的方法為熱波系統(tǒng)法。半導(dǎo)體檢測設(shè)備：檢測主要用于識別并定位產(chǎn)品表面存在的雜質(zhì)顆粒沾污、機(jī)械劃傷、晶圓圖案缺陷等問題。</p><div
