Abstract
本發明提供一種用於改良氮化矽蝕刻相對於氧化矽蝕刻之選擇性且可與習知磷酸濕式蝕刻組合物一起使用之組合物及方法。本發明描述用於抑制氧化矽及相關化合物再生長(亦即再沉積)於氧化矽表面上之添加劑。在某些實施例中,本發明提供結合至三烷氧基矽烷之某些經胺基取代之芳基化合物。
Description
本發明係關於一種在氧化矽、多晶矽及/或金屬矽化物之存在下選擇性蝕刻氮化矽之組合物及方法,且更特定言之係關於一種在高蝕刻速率下且以相對於氧化矽、多晶矽及/或金屬矽化物之暴露層或下伏層之高選擇性有效且高效地蝕刻氮化矽層之組合物及方法,特別是在多層半導體晶圓結構中。
隨著對改良之微電子裝置性能之持續需求,繼續強調減小裝置尺寸,此提供顯著增加裝置密度以及改良裝置性能之雙重優點。因為減小之裝置尺寸導致較短的需要待由載荷子(例如電子)行進之路徑,故改良裝置性能。
例如,金屬氧化物半導體場效電晶體(MOSFET)閘極電極具有作為電接觸點之閘極表面及源極區及汲極區。源極區與汲極區之間的距離形成閘極電極之通道長度,且因此,藉由減小裝置尺寸,通道長度同時減小。結果係增加裝置之切換速度。
不證自明的是,減小裝置尺寸導致微電子裝置晶片上裝置之封裝密度增加。此種增加之封裝密度極大地減少裝置之間互連路徑之長度,此減少此等互連路徑對總體裝置性能之相對負面影響(諸如阻性壓降、串擾(cross talk)或RC延遲)。
然而,此種要求引起寄生電容增加,裝置接觸電阻(MOSFET裝置中之閘極、源極及汲極接觸件)及圖案定義之公差嚴格之問題。對於極小亞微米或亞半微米或甚至亞四分之一微米現代矽裝置,用於圖案化接觸件之習知光刻技術將無法滿足所需的臨界尺寸公差。已為改良解析度及特徵尺寸而探索的方法包括形成自對準多晶矽(poly-Si)閘極結構,此有助於解決臨界尺寸公差之問題。使用該方法,針對閘極電極之源極及汲極形成之接觸點與poly-Si閘極自對準。
在形成自對準閘極結構期間遇到的一個問題係相對於多晶矽、氧化矽及/或金屬矽化物材料之氮化矽材料之選擇性移除。例如,在各向異性蝕刻覆蓋閘極電極之氮化矽層期間,下伏氧化矽層及矽基板亦經常被損壞,導致半導體裝置之可靠性下降。
用於選擇性移除氮化矽(Si
3N
4)之習知濕式蝕刻技術利用熱(約145至180℃)磷酸(H
3PO
4)水溶液,通常為85%磷酸與15%水(以體積計)。使用新製熱磷酸,典型Si
3N
4:SiO
2選擇性為約40:1。有利的是,隨著氮化物層之移除,水合氧化矽形成,此符合勒沙特列原理(Le Chatelier's principle),抑制自裝置表面另外移除氧化矽;因此,選擇性隨著使用而逐漸增加。與使用熱磷酸蝕刻相關之缺點包括金屬矽化物材料(例如閘極接觸材料)之腐蝕、氧化矽之蝕刻及由於與在製程溶液中維持特定量之水相關之難處所致之製程控制。另外,熱磷酸已成為適應單晶圓工具之困難介質,單晶圓工具越來越受許多製造商偏好。
選擇性移除氮化矽之另一方法包括使用包括氫氟酸之組合物,然而,該等組合物亦移除氧化矽。可透過稀釋達成約10:1之Si
3N
4:SiO
2選擇性;然而,氮化矽之蝕刻速率受損或必須使用高於環境之壓力。移除氮化矽之又另一方法包括使用鹵化氣態物質之乾式蝕刻移除;然而,Si
3N
4:SiO
2選擇性比率甚至比使用前述濕式蝕刻製程所獲得的更差。
目前所有主要記憶體晶片製造商處於開發中之3D-NAND結構由於由氧化物(PETEOS)界定之高縱橫比「狹縫」需要高選擇性蝕刻氮化矽(SiN)。在常規熱磷酸「熱磷」製程中,藉由預溶解特定量之氮化物來控制選擇性。經溶解之氮化矽轉化為微溶性氧化物;在蝕刻期間亦發生相同情況,但氧化物很快會開始沉積在狹縫的開口附近,最終將其阻塞。亦可參見US 2017/0287725,特別是圖1D,其顯示其中膠態二氧化矽之沉積傾向於「夾止」微電子裝置中之間隙或溝槽之示意圖。結果,蝕刻前氧化物濃度之製程窗極窄,難以控制,且蝕刻浴必須經常更換。因此需要使氧化物再沉積速率最小化。
另外,深狹縫需要長時間進行蝕刻(通常≥1小時)。少量添加HF會增加蝕刻速率,但亦會增加可溶性二氧化矽物質之聚合且因此提高氧化物再沉積速率。此外,HF及相關氟化物質之揮發性造成製程控制困難。
在平面NAND技術中,定標主要藉由光刻法驅動。在定標3D NAND中,需要極端精度及製程可重複性以建立具有極高縱橫比(HAR)特徵之複雜3D結構。因此,利用3D NAND達成成功需要將可變性最小化的創新圖案化解決方案。(參見Overcoming Challenges in 3D NAND Volume Manufacturing。固態技術網站:http://electroig.com/blog/2017/07/overcoming-challenges-in-3d-nand-volume-manufacturing/)
蝕刻極端HAR特徵之精度對於最佳化通道孔及溝槽用於單元訪問以及其獨特階梯結構架構至關重要,該階梯結構架構將單元連接至周圍CMOS電路以供讀取、寫入及擦除資料用。若記憶體堆疊之垂直間距為約50 nm,則96層堆疊為約4.8 µm高度。此對應於具有挑戰性的約100:1縱橫比。
另外,隨著多層堆疊高度增加,因此在記憶體陣列之頂部及底部處達成一致蝕刻及沉積概況之難度亦增加。例如,給定約100:1比,在記憶體堆疊中選擇性移除Si
3N
4成為濕式蝕刻挑戰。困難在於堆疊之頂部及底部處及跨晶圓一致移除Si
3N
4,而不會蝕刻任何SiO
2。在96層以下,使用熱磷酸(~160℃)進行該任務;然而,在96層及以上時,需要特殊調配之濕式蝕刻化學品以改良製程裕度(process margin)。
一般而言,本發明提供某些矽烷添加劑,其用於抑制氧化矽蝕刻,藉此改良氮化物蝕刻相對於氧化物蝕刻之選擇性且可與習知磷酸濕式蝕刻組合物一起使用。該等添加劑亦用於抑制氧化矽表面上的Si再生長(亦即,再沉積)。在某些實施例中,本發明提供結合至三烷氧基矽烷之某些經胺基取代之芳基化合物。此類化合物可用作磷酸濕式蝕刻組合物中之添加劑。

本發明之組合物可以多種特定調配物實施,如在後文中更充分地描述。
在所有此類組合物中,其中參考重量百分比範圍(包括零下限)論述組合物之特定組分,應明瞭,在組合物之各種特定實施例中,此類組分可存在或不存在,及在其中此類組分存在之情況下,基於採用此類組分之組合物之總重量計,其可以低至0.001重量百分比之濃度存在。
該組合物以可有效產生所需氮化矽蝕刻的量包括水性磷酸(例如濃磷酸)。術語「水性磷酸」係指與組合物之其他成分混合或組合以形成組合物之組合物之成分。術語「磷酸固體」係指水性磷酸成分或自水性磷酸成分製備的組合物之非水性組分。
組合物中所含的磷酸固體之量可為與蝕刻組合物之其他材料組合將提供所需蝕刻性能,包括所需氮化矽蝕刻速率及選擇性之量,此通常需要相對高的量(濃度)之磷酸固體。例如,蝕刻組合物可含有為基於組合物之總重量計至少約50重量百分比的量之磷酸固體,例如基於組合物之總重量計至少70或至少約80或85重量百分比磷酸固體。
為提供所需量之磷酸固體,該組合物可含有「濃」磷酸作為成分,其經與其他成分(一種成分視需要為水,呈某種形式)混合或組合以產生組合物。「濃」磷酸係指水性磷酸成分,其在低量或最小量之水存在下含有高量或最大量之磷酸固體且實質上沒有其他成分(例如,小於0.5或0.1重量百分比之任何非水或非磷酸固體材料)。濃磷酸通常可認為具有至少約80或85重量百分比磷酸固體在約15或20重量百分比水中。或者,該組合物可認為包括一定量之經水稀釋之濃磷酸,意指例如在與蝕刻組合物之其他成分組合之前或之後已經一定量之水稀釋之濃磷酸或以任何方式形成之等效物。作為另一替代,組合物之成分可係濃磷酸或稀磷酸,且蝕刻組合物可包含額外量之水,其經提供至組合物作為不同成分之組分或作為單獨水成分。
作為一個實例,若使用濃磷酸以形成組合物,則濃磷酸之量(85重量百分比,在水中)可為基於組合物之總重量計為至少60,例如至少80或至少90、93、95或至少98重量百分比之組合物之量。在磷酸固體濃度為大於85%之實施例中,此一般係藉由蒸發濃酸中所含的一些水,或藉由添加固體(99至100%)磷酸或磷酸寡聚物(諸如焦磷酸)來獲得。
組分(c)為包含水之溶劑。視需要,溶劑可進一步包含一或多種可與水混溶之溶劑,諸如吡咯啶酮、二醇、胺及二醇醚,包括(但不限於)甲醇、乙醇、異丙醇、丁醇及高碳數醇(諸如C

視需要,該等組合物可進一步包含一定量之羧酸化合物,意指含有至少一個羧酸基之有機化合物。根據本發明,如所述的組合物中羧酸化合物之存在可藉由抑制氧化矽之再沉積或其顆粒之形成來改善性能。在某些實施例中,用於組合物中之羧酸化合物包括(但不限於)乙酸、丙二酸、草酸、單烷基及2,2-二烷基丙二酸、琥珀酸、2-甲基琥珀酸、戊二酸、己二酸、水楊酸、1,2,3-丙三羧酸(又名三碳烯酸)、2-膦醯基乙酸、3-膦醯基丙酸及2-膦醯基丁烷-1,2,4-三羧酸(PBTCA),其中之任何者可單獨使用,彼此共同組合使用,或與不同羧酸化合物組合使用。視需要包括膦酸,諸如艾提壯酸(etidronic acid)、氮基三(亞甲基膦酸)、乙二胺四(亞甲基膦酸)、二伸乙基三胺五(亞甲基膦酸)、辛基膦酸及苯基膦酸。
組合物中所含之羧酸化合物(包括其衍生物)的量可為與組合物之其他材料組合將提供期望的蝕刻性能,而又不影響蝕刻組合物之性能或化學穩定性的量。例如,該等組合物可含有在基於組合物之總重量計約0.01至10重量百分比或基於組合物之總重量計約0.1至約5或8重量百分比之範圍內之量之羧酸化合物,其可為單一物質或兩種或更多種物質之組合。
該組合物可含有來自一種來源或來自多種來源之水。例如,水將存在於水性磷酸成分中。另外,水可用作蝕刻組合物之其他成分中之一者或多者之載劑,及水可作為其自身成分單獨添加。水之量應足夠低以使組合物展現所需或較佳或有利之蝕刻性能性質,包括可用(足夠高)之氮化矽蝕刻速率。水之存在之增加傾向於增加氮化矽之蝕刻速率但亦可降低蝕刻組合物之沸點,此迫使蝕刻組合物之操作溫度降低及相反效應。蝕刻組合物中來自所有來源之水之量之實例可為基於組合物之總重量計小於約50、40或30重量百分比,例如在約5重量百分比至約25重量百分比之範圍內,或在基於組合物之總重量計約10至20重量百分比水。
視需要,如所述的此等及其他實例組合物可含有磷酸、包含水之溶劑、組分(a)材料及所識別的可選成分之任何一者或任何組合,由其組成,或基本上由其組成。本發明之組合物之某些實施例不需要且可排除通常不包括在蝕刻組合物中之其他類型之成分,諸如pH調整劑(除了本文中作為潛在成分提及之酸以外)及固體材料(諸如磨料顆粒)。
在本發明之某些實施例中,所述的組合物提供一種自微電子裝置移除氮化矽之方法,該方法包括使微電子裝置與本發明之組合物在在足以自微電子裝置至少部分地移除該氮化矽材料之條件下接觸足夠時間。
例如,可在實質上不損壞金屬及金屬矽化物互連材料下移除氮化矽材料。因此,本發明提供使用本文所述的組合物自微電子裝置之其上具有多晶矽及/或氧化矽材料之表面相對於該等多晶矽及/或氧化矽材料選擇性地且實質上移除氮化矽材料之方法。使用該方法,存在的金屬矽化物材料實質上不會被該移除組合物腐蝕。
在蝕刻應用中,以任何適宜方式將組合物施覆於微電子裝置之其上具有氮化矽材料之表面,例如藉由將移除組合物噴塗在裝置之表面上,藉由將包括氮化矽材料之裝置浸入(於靜態或動態體積之移除組合物中),藉由使裝置與另一材料(例如其上吸附有移除組合物之墊或纖維狀吸附劑施用元件)接觸,藉由使包括氮化矽材料之裝置與循環移除組合物接觸,或藉由任何其他適宜手段、方式或技術,藉由該適宜手段、方式或技術使得移除組合物與氮化矽材料移除接觸。該施覆可在批式或單晶圓設備中,以進行動態或靜態清潔。在一個實施例中,將移除組合物施覆於微電子裝置之表面係受控式攪動,由此使組合物循環通過容納該組合物之容器。當矽化物及/或poly-Si之蝕刻速率較佳為低時,不建議進行主動攪動,例如湍流、攪拌等。然而,為了自高縱橫比結構移除氮化矽,可能需要攪拌,以使液體更快速地進出結構交換且最小化氧化物之再沉積。
本發明之組合物由於其相對於可存在於微電子裝置結構上且暴露於該組合物之其他材料(諸如金屬化、多晶矽、氧化矽等)對氮化矽材料之選擇性而以高效且高選擇性方式達成至少部分地移除氮化矽材料。
在使用本發明之組合物自其上具有氮化矽材料之微電子裝置結構移除氮化矽材料時,通常使該組合物與微電子裝置結構在包括(但不限於)在一個實施例中約60℃至約120℃或在另一個實施例中約100℃至約250℃之範圍內之溫度之足夠條件下對於單個晶圓工具而言接觸一段約1分鐘至約200分鐘,在一個實施例中,約15分鐘至約100分鐘,或約1分鐘至約5分鐘之足夠時間。此等接觸時間及溫度係說明性的,且可採用在本發明之實務中可有效地自裝置結構至少部分地移除氮化矽材料之任何其他適宜時間及溫度條件。
在達成所需移除作用之後,如在本發明之組合物之給定的最終用途應用中可為所需且有效的,容易地例如藉由沖洗、洗滌或其他移除步驟自其先前已施覆於其上之微電子裝置移除移除組合物。例如,裝置可用沖洗溶液(包括去離子水)沖洗及/或乾燥(例如旋塗乾燥、N
2、蒸汽乾燥等)。
本發明之組合物自微電子裝置之表面相對於poly-Si及氧化矽選擇性地蝕刻氮化矽材料。例如,在本發明之移除組合物存在下,氮化矽相對於氧化矽之選擇性係在約10:1至約7,000:1,在另一個實施例中約30:1至約3,000:1,且在另一個實施例中約100:1至約2000之範圍內。當矽酸來源包括烷氧基矽烷(例如,TEOS)時,氮化矽相對於氧化矽之選擇性在一個實施例中可自約20:1調諧至無窮大及在另一個實施例中在約20:1至約7,000:1之範圍內。
本說明描述之蝕刻步驟可用於自任何類型之基板之表面蝕刻氮化矽材料。根據特定實施例,基板可包括氮化矽之交替薄膜層作為基板之結構特徵,該基板包括氮化矽層與氧化矽之交替薄膜層。氧化矽層係高縱橫比結構,其含有設置在氧化矽層之間的氮化矽層。
本發明之又另一個態樣係關於製造包含微電子裝置之製品之方法,該方法包括使微電子裝置與本發明之組合物接觸足夠的時間以自微電子裝置之其上具有氮化矽材料之表面蝕刻移除氮化矽材料,且將該微電子裝置併入該製品中。
藉由簡單地加入各自成分且混合至均勻條件,可容易地調配本文所述的組合物。此外,該等組合物可容易地調配成單包裝調配物或在使用點(point of use)混合的多部分調配物。可在工具處或在工具上游的儲槽中混合多部分調配物之各個部分。各自成分之濃度可以組合物之特定倍數廣泛地變化,亦即更稀或更濃,且應明瞭,本文所述的組合物可不同地或可替代地包含與本文揭示內容一致的成分之任何組合,由其組成或基本上由其組成。
本發明之另一個態樣係關於一種套組,其在一或多個容器中包括適於形成本文所述的組合物之一或多種組分。在一個實施例中,該套組在一或多個容器中包括以上成組分(A)至(C)中之至少一者之組合以用於在工廠或使用點與水組合。套組之容器必須適於儲存及運輸該等清潔組合物組分,例如NOWPak®.容器(Entegris, Inc.,Danbury, Conn.,USA)。含有第一清潔組合物之組分之一或多個容器較佳包括用於使組分在該一或多個容器中流體連通以進行摻合及施配之構件。例如,參考NOWPak®.容器,可施加氣壓於該一或多個容器中襯裡之外部以使襯裡之內含物之至少一部分被排出且由此使流體連通以進行摻合及施配。或者,可將氣壓施加於習知可加壓容器之頂部空間或可使用泵以使流體連通。另外,該系統較佳包括用於將經摻合之清潔組合物施配至處理工具之施配埠。
實質上化學惰性、無雜質、撓性及彈性聚合物膜材料(諸如高密度聚乙烯)可用於製造該一或多個容器之襯裡。期望之襯裡材料可進行加工而無需共擠出或障壁層且無需任何顏料、UV抑制劑或加工劑,其等可不利地影響待設置在襯里中之組分之純度要求。期望之襯裡材料之清單包括包含原始(無添加劑)聚乙烯、原始聚四氟乙烯(PTFE)、聚丙烯、聚胺甲酸酯、聚偏二氯乙烯、聚氯乙烯、聚縮醛、聚苯乙烯、聚丙烯腈、聚丁烯等之膜。此類襯裡材料之示例性厚度係在約5密耳(0.005英寸)至約30密耳(0.030英寸)之範圍內,如例如20密耳(0.020英寸)之厚度。
關於該等套組之容器,以下專利及專利申請案之揭示內容係以各自全文之引用方式併入本文中:美國專利第7,188,644號,標題為「APPARATUS AND METHOD FOR MINIMIZING THE GENERATION OF PARTICLES IN ULTRAPURE LIQUIDS」;美國專利第6,698,619號,標題為「RETURNABLE AND REUSABLE, BAG-IN-DRUM FLUID STORAGE AND DISPENSING CONTAINER SYSTEM」;及2007年5月9日以John E.

因此,在另一個態樣中,本發明提供一種套組,其包含一或多個其中具有適於自微電子裝置移除氮化矽之組分之容器,其中該套組之一或多個容器含有如本文所述的組分(a)、(b)及(c)。
