Description
相關申請案之相互參照 本申請案主張2017年8月25日提出的美國臨時申請案62/550,428之優先權,其整體內容於此以參考之方式併入本文用於全部允許的目的。
發明領域 本發明係關於一種使用於半導體裝置製造的水性蝕刻溶液。更特別是,本發明提供一種增加在矽-鍺/氧化矽複合式半導體裝置中之矽-鍺合金膜對二氧化矽膜的蝕刻選擇性之水性蝕刻溶液。
伴隨著連續不斷地縮小比例及對超高密度積體電路之速度及功能性的要求需求增加,習知的平面金氧半場效電晶體(MOSFETs)面對到增加的挑戰,諸如閘極氧化物厚度縮小及在通道區域上的閘極電極之靜電控制等問題。鰭狀場效應電晶體(FinFETs)已藉由在鰭狀通道的三邊上纏繞該閘極電極而具有超過平面閘極MOSFET設計之經改良的控制。
GAA MOSFETs類似於FinFETs,但是因為閘極電極完全包圍通道,其在通道上具有甚至較大的靜電控制之潛力。在GAA MOSFET中,該通道區域基本上係奈米線。該奈米線通道典型具有厚度(或直徑)在數十奈米(nm)或較少內及具有不受約束的長度。該奈米線通道通常水平懸浮在該GAA MOSFET之更大的源極與汲極區間且錨定於此。
該GAA MOSFETs可使用完全相容的CMOS技術在塊體矽基材上進行製造。在GAA MOSFET中形成該通道區域的典型製造方法包括於塊體基材之頂端上磊晶生長一堆疊(磊晶堆疊),其中在該等通道層間夾有一犧牲層。該犧牲層及通道層係由二種不同材料構成,以便可藉由選擇性蝕刻來移除該犧牲層。
以實施例說明之,該磊晶堆疊可由交替的矽(Si)與矽鍺(SiGe)層形成,其中該SiGe層係犧牲層及該Si層係通道層。然後,可藉由選擇性蝕刻(例如,經由溼式蝕刻方法,諸如過氧化氫溶液)來移除SiGe層,且亦由於構成該犧牲層與基材的材料類似性,其會非故意地將溝槽鑲嵌進該塊體基材中。一旦移除SiGe層,隨後該Si層可懸浮在該溝槽上而形成奈米線通道。然後,繞著該Si奈米線通道及在該基材的鑲嵌溝槽上配置一薄閘極介電質。然後,將金屬配置在該介電質上以形成該GAA MOSFET的金屬閘極電極。
習知用以蝕刻SiGe合金的溼式化學蝕刻溶液典型使用氧化劑及氧化物移除試劑。最常見的溶液係用於氧化矽蝕刻之HF,及用於SiGe氧化之過氧化氫(H2
O2
)與醋酸(CH3
COOH)溶液。H2
O2
/CH3
COOH混合物對Si1-x
Gex
具有超過Si的高選擇性且具有改良的平滑度,但是,此化學物質在移除垂直堆疊的矽-鍺上不如此有效且其與氮化物/氧化物遮罩不相容。
此外,於技藝中,對在犧牲SiGe層移除期間能對該蝕刻方法提供較好的控制而不會遭遇到上述提及之缺點的矽-鍺蝕刻組合物,及使用該組合物來例如形成在GAA MOSFETs中的Si奈米線通道之方法有需求。

在某些具體實例中,本發明的組合物將無或實質上無上述列出之界面活性劑的任何或全部。 緩衝劑(選擇性)
該蝕刻組合物選擇性包括一緩衝組合物。典型來說,該緩衝組合物包含如下列詳述之胺化合物及多功能性有機酸、基本上由其組成或由其組成。 胺化合物(緩衝劑)(選擇性)
在某些具體實例中,本揭示之蝕刻組合物的選擇性緩衝組合物包含二級或三級有機胺。該二級或三級有機胺主要作用為提供該緩衝劑之共軛鹼組分。
在本揭示的某些較佳具體實例中,該使用作為緩衝組分之二級或三級有機胺化合物的實施例包括烷醇胺。較佳的烷醇胺包括具有1至5個碳原子之二級及/或三級的低級烷醇胺。此烷醇胺的實施例包括二乙醇胺、二及三異丙醇胺、2-(2-胺基乙基胺基)乙醇、2-(2-胺基乙氧基)乙醇(AEE)、三乙醇胺、N-乙基乙醇胺、N,N-二甲基乙醇胺、N,N-二乙基乙醇胺、N-甲基二乙醇胺、N-乙基二乙醇胺、環己基胺二乙醇及其混合物。
在較佳具體實例中,該胺化合物係一選自於由下列所組成之群的烷醇胺:三乙醇胺(TEA)、二乙醇胺、N-甲基二乙醇胺、二異丙醇胺、N-甲基乙醇胺、2-(2-胺基乙氧基)乙醇(AEE)及其混合物。
咸信對大部分應用來說,以該組合物的總重量為基準,於該組合物中的胺化合物量將包含在具有開始及結束點係選自於下列重量百分比的任何範圍內:0.1、0.2、0.5、0.6、0.9、1、1.5、2、3、4、5、8、10、12、15、20及30,例如,該組合物的約10%至約30重量%,或約20%至約30%,或約0.5%至約10%,或約0.6%至約5%,或約0.5%至約8%,或該組合物之約0.5%至約3重量%。
較佳的是,該胺化合物具有pKa<9.0。 多功能性有機酸(緩衝組分)
在某些具體實例中,本揭示之蝕刻組合物的選擇性緩衝組合物包含一或多種多功能性有機酸,其主要作用為該緩衝劑的共軛酸部分。如於本文中所使用,用語「多功能性有機酸」指為酸或具有多於一個羧酸鹽基團的多酸,其包括但不限於:(i)二羧酸鹽酸(諸如丙二酸、蘋果酸等等)、含有芳香族部分的二羧酸(諸如酞酸等等)及其組合;及(ii)三羧酸(諸如檸檬酸等等)、含有芳香族部分的三羧酸(諸如偏苯三酸等等)及其組合。
有用的二羧酸包括草酸、丙二酸、琥珀酸、戊二酸、己二酸、庚二酸、辛二酸、壬二酸及癸二酸。
在某些具體實例中,用於該緩衝系統的較佳酸有具有至少三個羧酸基團之多質子酸。此等酸具有至少第二及第三解離常數,其各者相對於其各別的前述常數係較高。此指示出比起失去第二質子,該酸更容易失去第一質子,因為該第一質子係與單一負電荷離子分開,然而該第二質子係與雙負電荷離子分開。咸信雙負電荷強烈地將質子吸回該酸離子。類似關係存在於該第二與第三分開的質子間。因此,諸如例如,具有至少三個羧酸基團的那些多質子酸在控制溶液之pH上係有用,特別在與其較高pKa值相應的pH處。因此,除了具有pKa值約5至約7外,本發明的較佳多質子酸具有多重pKa值,其中最高的pKa係約5至約7。
根據本發明之具有至少三個羧酸基團的多質子酸係與多羥基溶劑高度相容。較佳的多質子酸之實施例包括三羧酸(例如,檸檬酸、2-甲基丙烷-1,2,3-三羧酸、苯-1,2,3-三羧酸[半蜜蠟酸]、丙烷-1,2,3-三羧酸[丙三羧酸]、1,順-2,3-丙烯三羧酸[烏頭酸]及其類似物)、四羧酸(例如,丁烷-1,2,3,4-四羧酸、環戊烷四-1,2,3,4-羧酸、苯-1,2,4,5-四羧基[苯均四酸]及其類似物)、五羧酸(例如,苯五羧酸)及六羧酸(例如,苯六羧酸[蜜蠟酸])及其類似物。這些酸的各別pKa值係提供在表1中。特別佳的多質子酸包括三羧酸,且檸檬酸最佳。 表1
較佳的多質子酸檸檬酸係具有三個pKa值的三羧酸:3.13、4.76及6.40,其各別與三氫檸檬酸鹽離子、二氫檸檬酸鹽離子及單氫檸檬酸鹽離子相應。在本發明的某些較佳具體實例中,該緩衝系統包含檸檬酸的鹽,且特別佳的緩衝劑包含三元檸檬酸銨(TAC)與檸檬酸之水溶液。
在任擇的具體實例中,可於本發明之組合物中使用其它多功能性有機酸(如僅對檸檬酸所描述般)與其各別鹽,通常為各別多功能性酸之銨鹽,例如,丙二酸及丙二酸銨鹽;草酸及草酸銨;及琥珀酸及琥珀酸銨等等。
咸信在本發明的組合物中之多功能性有機酸的量將以重量百分比計,以該組合物之總重量為基準,其在具有開始及結束點係選自於下列之任何範圍內:0.1、0.25、0.4、0.5、0.6、0.8、0.9、1、1.5、2、3、4及5,例如,該組合物的約10%至約30重量%,或約20%至約30%,或約0.5%至約10%,或約0.6%至約5%,或約0.5%至約8%,或約0.5%至約3重量%,約0.1重量%至5重量%,較佳為0.25重量%至3重量%,及更佳為0.5重量%至2.0重量%。
例如,該共軛鹼可以具有開始及結束點係選自於下列之任何範圍存在於該組合物中,以重量百分比計,以該組合物的總重量為基準:0.1、0.25、0.4、0.5、0.6、0.8、0.9、1、1.5、2、3、4及5,例如,該組合物的約10%至約30重量%,或約20%至約30%,或約0.5%至約10%,或約0.6%至約5%,或約0.5%至約8%,或約0.5%至約3重量%,約0.1重量%至5重量%,較佳為0.25重量%至3重量%,及更佳為0.5重量%至2.0重量%。在某些具體實例中,若該共軛鹼(諸如銨鹽)係存在於該組合物中時,其對該多功能性酸可以10:1至1:10之重量比率呈現,或5:1至1:5之重量比率,以存在於該組合物中的多功能性酸量為基準。
較佳的是,所揭示的蝕刻組合物之緩衝組合物會緩衝該組合物,如此它們係酸性。在某些具體實例中,該pH係約2至約7,或約4至約6.5。 其它選擇性成份
本發明的蝕刻組合物亦可包括一或多種下列添加劑:螯合劑、化學改質劑、染料、滅菌劑及其它添加劑。該添加劑可加入的程度為它們不會相反地影響該組合物之性能。

咸信該螯合劑若存在時,其在該組合物中的量將係約0.1重量%至約10重量%,較佳量為該組合物的約0.5重量%至約5重量%。
在某些具體實例中,本發明的組合物將無或實質上無任何或全部上述列出的螯合劑加入至該組合物。
可在該清洗組合物中包括習知量的其它普通已知組分,諸如染料、滅菌劑等等,例如,其量最高總共係該組合物的約5重量%。
在某些具體實例中,該組合物可實質上無或無下列之一或多種:氫氧化物、金屬氫氧化物,諸如KOH、或LiOH、或NaOH。在其它具體實例中,除了一或多種含氟化合物外,該組合物可實質上無或無含鹵化物化合物,例如,其可實質上無或無含溴、氯或碘化合物之一或多種。在其它具體實例中,該組合物可實質上無或無磺酸、及/或磷酸、及/或硫酸、及/或硝酸、及/或鹽酸。在其它具體實例中,該組合物可實質上無或無硫酸鹽、及/或硝酸鹽、及/或亞硫酸鹽、及/或亞硝酸鹽。在其它具體實例中,該組合物可實質上無或無氫氧化銨及/或乙基二胺。在其它具體實例中,該組合物可實質上無或無含鈉化合物、及/或含鈣化合物、及/或含錳化合物、或含鎂化合物、及/或含鉻化合物、及/或含硫化合物。

本發明的蝕刻溶液組合物典型藉由在室溫下於容器中一起混合該等組分直到全部固體已溶解在水性基底媒質中來製備。 方法
在另一個態樣中,有提供一種選擇性提高在包含矽及矽-鍺的微電子(複合式半導體)裝置上之矽-鍺相對於矽的蝕刻速率之方法,該方法其步驟包括:讓該包含矽及矽-鍺的微電子(複合式半導體)裝置與一包含水、氧化劑、水溶混性有機溶劑、氟離子來源及選擇性界面活性劑之水性組合物接觸;及在至少部分移除矽-鍺後,沖洗該微電子(複合式半導體)裝置,其中該矽-鍺對矽的蝕刻選擇性係大於約5、或10、或15、或20、或25、或30、或65、或80。在某些具體實例中,該矽-鍺對矽的蝕刻選擇性係來自例如具有複數層(多於一層)交替水平堆疊的SiGe及Si層,如顯示於圖1中。亦可在該方法中包括額外的乾燥步驟。「至少部分移除」意謂著移除至少50%的該材料,較佳為移除至少80%。最佳的是,使用本發展之組合物達成100%的矽-鍺移除。

在該接觸步驟後係一選擇性沖洗步驟。該沖洗步驟可藉由任何合適的方法進行,例如,藉由沈浸或噴灑技術以去離子水沖洗該基材。在較佳具體實例中,可使用去離子水與有機溶劑諸如例如異丙醇之混合物來進行該沖洗步驟。
在該接觸步驟及選擇性沖洗步驟後係一選擇性乾燥步驟,其係藉由任何合適的方法進行,例如,異丙醇(IPA)蒸氣乾燥、加熱或藉由向心力。
下列討論的闡明性實施例更完整地顯示出特徵及優點。 實施例 用以製備清洗組合物的一般程序

於250毫升燒杯中,使用100克的蝕刻組合物與設定在400 rpm之½”圓鐵弗龍攪拌棒來進行蝕刻測試。在加熱板上將該蝕刻組合物加熱至溫度約45℃。將測試試樣沈浸在該組合物中約20分鐘,同時攪拌。
然後,在DI水槽中或以噴灑來沖洗該等斷片3分鐘,隨後使用經過濾的氮進行乾燥。從蝕刻前後之厚度變化及藉由橢圓偏振儀光譜(MG-1000,Nano-View Co., Ltd.,South Korea,我們使用SCI FilmTek SE2000)測量來估計該矽及矽-鍺蝕刻速率。對Si來說,典型的起始層厚度係1000埃,及對SiGe來說係1000埃。 實施例組1 實施例1
