1、研磨拋光液對(duì)CMP研磨拋光工藝的影響 畢業(yè)設(shè)計(jì)(論文)報(bào)告 題目研磨拋光液對(duì)CMP研磨拋光工藝的影響 7>2013年4月研磨拋光液對(duì)CMP研磨拋光工藝的影響摘要:半導(dǎo)體科學(xué)在現(xiàn)代科學(xué)技術(shù)中占有極其重要的地位。它廣泛應(yīng)用于國(guó)民經(jīng)濟(jì)的各個(gè)領(lǐng)域中,它的發(fā)展推動(dòng)著人類社會(huì)的進(jìn)步和物質(zhì)文化生活水平的提高,由其興起的半導(dǎo)體產(chǎn)業(yè)越來越受到各國(guó)的重視,自20世紀(jì)以來取得了長(zhǎng)足的發(fā)展。本文主要采用了文獻(xiàn)研究法和調(diào)查法,通過查找互聯(lián)網(wǎng)和書籍文獻(xiàn),及在從事
2、半導(dǎo)體產(chǎn)業(yè)的工廠中的實(shí)習(xí),獲得了大量的資料。本文主要研究半導(dǎo)體產(chǎn)業(yè)的相關(guān)知識(shí),說明半導(dǎo)體產(chǎn)業(yè)在國(guó)內(nèi)國(guó)外目前的發(fā)展歷史并討論半導(dǎo)體產(chǎn)業(yè)的發(fā)展應(yīng)用。隨著半導(dǎo)體技術(shù)愈加精細(xì)化,晶圓尺寸由6英寸(150mm),8英寸(200mm),12英寸(300mm),甚至未來的18英寸(450mm)從而越來越大,在半導(dǎo)體領(lǐng)域中化學(xué)機(jī)械拋光CMP占有著越來越重要的作用,本文在分析CMP工藝的基礎(chǔ)上,及初步了解與分析了CMP半導(dǎo)體晶片過程中拋光液的重要作用,總結(jié)了拋光液的組成及其化學(xué)性能氧化劑、磨料及pH值等和物理性能流速、
3、粘性及溫度對(duì)拋光效果的影響規(guī)律。本文是在前人研究的基礎(chǔ)上,進(jìn)行深入了解,希望從而對(duì)半導(dǎo)體產(chǎn)業(yè)向前發(fā)展起到一定的積極作用。 關(guān)鍵詞:半導(dǎo)體,化學(xué)機(jī)械拋光,拋光液 Grindingandpolishingliquid'sinfluenceontheCMPpolishingprocessAbstract:Semiconductorscienceoccupiesanextremelyimportantpositioninmodernscienceandtechnology.It
