Description

使用自組裝單層的選擇性沉積的方法
本案揭露內容大致上關於用於使用自組裝單層選擇性沉積的方法。
選擇性原子層沉積(ALD)和化學氣相沉積(CVD)製程能夠有利地減少習知微影術中涉及的步驟數目和成本,同時跟上元件尺寸縮小的步調。在後端產線(BEOL)應用中,以金屬介電質圖案選擇性沉積有高度的潛在價值。已出現的一些替代性選擇性基於矽的介電質沉積技術是模板控制式的生長、基於全像(holographic)的微影術、及類似技術。然而,由於在大氣條件下與金屬氧化物形成相關的限制之故,這些替代性技術中無一技術提供完整的解決方案。發明人已觀察到,金屬的本質引起了嚴峻的挑戰,例如在金屬表面上存在著原生氧化物。因為金屬氧化物可作用如介電質,所以薄層的原生氧化物使得金屬表面無法與用於自組裝單層(SAM)的介電質表面區分,而導致選擇性降低或是選擇性損失。
因此,發明人已開發使用自組裝單層作為犧牲層與成核抑制層的選擇性介電質沉積的改良方法和設備。
本文提供用於選擇性沉積的方法和設備。在一些實施例中,一種方法包括:在具有金屬表面和介電質表面的基板頂上沉積層,包括:(a)使該金屬表面接觸一或多種金屬鹵化物,而形成暴露的金屬表面;(b)在該介電質表面頂上生長基於有機矽烷的自組裝單層;及(c)在該基板之該暴露的金屬表面頂上選擇性沉積一層,其中該基於有機矽烷的自組裝單層抑制該層在該介電質表面頂上的沉積。在多個實施例中,該金屬鹵化物是金屬氯化物、金屬氟化物、鹼金屬氯化物、或上述鹵化物之組合。
在另一實施例中,提供一種調節具有金屬表面和介電質表面的基板的方法,包括使該金屬表面接觸一種或多種金屬鹵化物,而形成暴露的金屬表面,其中該暴露的金屬表面抑制該表面上的基於有機矽烷的自組裝單層的沉積。在多個實施例中,該金屬鹵化物是金屬氯化物、金屬氟化物、鹼金屬氯化物、或上述鹵化物之組合。
在一些實施例中,一種方法包括:在具有金屬表面和介電質表面的基板頂上選擇性沉積層,包括:(a)使該金屬表面接觸一種或多種金屬氯化物、金屬氟化物、或上述材料之組合,而形成暴露的金屬表面;(b)在該介電質表面頂上生長基於有機矽烷的自組裝單層;及(c)在該基板的該暴露的金屬表面頂上選擇性沉積一層,其中該基於有機矽烷的自組裝單層抑制該層在該介電質表面頂上的沉積。
在一些實施例中,本案揭露內容關於一種電腦可讀媒體,在該電腦可讀媒體上儲存有多個指令,當執行該等指令時,該等指令引發處理腔室執行在具有金屬表面和介電質表面的基板頂上選擇性沉積層的方法,該方法包括:(a)使該金屬表面接觸一種或多種金屬鹵化物,而形成暴露的金屬表面;(b)在該介電質表面頂上生長基於有機矽烷的自組裝單層;及(c)在該基板的該暴露的金屬表面頂上選擇性沉積一層,其中該基於有機矽烷的自組裝單層抑制該層在該介電質表面頂上的沉積。
以下描述本案揭露內容的其他及進一步的實施例。
本文提供使用自組裝單層(SAM)進行選擇性沉積的方法。在一些實施例中,本文所述的方法藉由使金屬表面接觸一或多種金屬鹵化物(例如金屬氯化物、金屬氟化物、及類似物),而形成暴露的金屬表面,以有利地調節具有金屬表面和介電質表面的基板,其中該暴露的金屬表面抑制在該表面上的基於有機矽烷自組裝單層的沉積。暴露的金屬表面有利地不包括有問題的氧化物層,該有問題的氧化物層可能會促進基於有機矽烷的自組裝單層在該氧化物層上的沉積並且限制或破壞該製程的選擇性。
圖2是根據本案揭露內容的一些實施例的處理具有金屬表面和介電質表面的基板的方法200的流程圖。圖3A至圖3E是根據本案揭露內容的一些實施例的在圖2之處理序列的不同階段期間的基板的說明性剖面視圖。本案揭露內容的方法可以在組裝成用於原子層沉積(ALD)或化學氣相沉積(CVD)的處理腔室中執行,例如下面與圖1相關地討論的處理腔室。
方法200在基板300上執行,如圖3A所描繪,該基板300具有金屬表面302及介電質表面304。在多個實施例中,基板300可包括諸如下述材料:結晶矽(例如,Si<100>或Si<111>)、矽鍺、摻雜或未摻雜的多晶矽、摻雜或未摻雜的矽晶圓、圖案化或非圖案化的晶圓、絕緣體上覆矽(SOI)、碳摻雜的氧化矽、氮化矽、摻雜矽、鍺、砷化鎵、玻璃、藍寶石、及上述材料之組合。在實施例中,基板300可具有各種尺寸,對於圓形基板而言,諸如200mm、300mm、450mm、或其他直徑。基板300也可以是任何多邊形、正方形、矩形、彎曲或其他非圓形工件,諸如用在製造平板顯示器中的多邊形玻璃基板。除非另有註記,否則本文所述的實施方式和範例在諸如基板300的基板上進行,該基板具有200mm直徑、300mm直徑、或450mm直徑。
在多個實施例中,介電質表面304與金屬表面302並不相同。在一些實施例中,介電質表面304藉由任何適合的原子層沉積製程或化學層沉積製程沉積。在一些實施例中,介電質表面304可包括沉積在基板300頂上的低k介電質層。在一些實施例中,介電質表面304可包括適合用於半導體元件製造的任何低k介電質材料。適合作為低k介電質材料的非限制性材料可包括含矽材料,例如氧化矽(SiO2)、氮化矽、或氮氧化矽(SiON)。在多個實施例中,低k介電質材料可具有小於約3.9的低k值(例如,約2.5至約3.5)。在一些實施例中,介電質表面304可包括氧化鉿,例如HfOx
在一些實施例中,藉由任何適合的原子層沉積製程或化學層沉積製程沉積金屬表面302。在一些實施例中,該金屬表面302可包括適合用於半導體元件製造的任何金屬。適用於金屬表面302的非限制性金屬包括:銅(Cu)、鈷(Co)、鎢(W)、鈮(Nb)、釕(Ru)、或鉬(Mo),以及上述金屬的組合,諸如合金,及類似物。參照圖3A,顯示金屬氧化物層305配置在金屬表面302頂上。金屬氧化物層305可以是原生氧化物層或形式,這是由於金屬表面302接觸例如在空氣或水中的氧而造成。金屬氧化物層305是有問題的,原因在於,金屬氧化物層305作用如介電層或是會促進基於有機矽烷的自組裝單層的沉積在該金屬氧化物層上。在金屬氧化物層305和金屬表面302頂上形成基於有機矽烷的自組裝單層可以抑制或減少選擇性沉積方法的選擇性。在多個實施例中,在沉積自組裝單層306之前移除金屬氧化物層305。
根據本案揭露內容,方法200開始於210,並且如圖3A和3B所描繪,該方法的開始是藉由下述方式進行:使金屬表面接觸一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物及類似物),而形成暴露的金屬表面308。藉由選擇一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物),暴露的金屬表面308形成為無金屬氧化物層305或實質上無金屬氧化物層305,並且暴露的金屬表面308無法使自組裝單層(SAM)與該表面結合。暴露的金屬表面之材料的非限制性範例包括:實質上純的(例如,實質上無氧化物的)銅(Cu)、鈷(Co)、鎢(W)、鈮(Nb)、釕(Ru)或鉬(Mo)及上述材料之組合(諸如合金)及類似物。
在多個實施例中,該一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物)以足以移除金屬氧化物層305的量接觸金屬表面302。例如,該一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物)可以在金屬表面302頂上蝕刻金屬氧化物層305,而形成暴露的金屬表面308,如圖3B所示。在多個實施例中,使用足以移除金屬氧化物層305的一或多種金屬鹵化物(例如金屬氯化物或金屬氟化物)的量在適合反應的條件下使金屬表面302接觸一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物)。在多個實施例中,使金屬表面302接觸一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物)是在如下所述之第一溫度執行:約攝氏300度至約攝氏400度、或約攝氏325度至約攝氏375度、或約攝氏325度、約攝氏350度、或約攝氏375度。在多個實施例中,使金屬表面302接觸一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物)是在下述量的壓力下執行:1至15托、約1至約15托、約5托、約10托、或約15托。在多個實施例中,使金屬表面302接觸一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物)是以下述時間執行:約5至約20分鐘,諸如約10分鐘至約15分鐘。在多個實施例中,使金屬表面與一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物)接觸執行達5至20分鐘。
在一些實施例中,一或多種鹼金屬鹵化物以足以移除金屬氧化物層305的量接觸金屬表面302。例如,該一或多種鹼金屬鹵化物可蝕刻金屬表面302頂上的金屬氧化物層305,而形成暴露的金屬表面308,如圖3B所示。在多個實施例中,使用足以移除金屬氧化物層305的一或多種鹼金屬鹵化物的量在適合反應的條件下執行金屬表面302與一或多種鹼金屬鹵化物的接觸。在多個實施例中,使金屬表面302接觸一或多種鹼金屬鹵化物是在如下所述之第一溫度執行:約攝氏300度至約攝氏400度、或約攝氏325度至約攝氏375度、或約攝氏325度、約攝氏350度、或約攝氏375度。在多個實施例中,使金屬表面302接觸一或多種鹼金屬鹵化物是在下述量的壓力下執行:1至15托、約1至約15托、約5托、約10托、或約15托。在多個實施例中,使金屬表面302接觸一或多種鹼金屬鹵化物執行達下述時間:約5至約20分鐘、諸如約10分鐘至約15分鐘。在多個實施例中,使金屬表面接觸一或多種鹼金屬鹵化物達5至20分鐘。鹼金屬鹵化物的非限制性範例包括:鹼金屬氟化物、鹼金屬氯化物、鹼金屬溴化物、鹼金屬碘化物、鹵化鋰、鹵化鈉、鹵化鉀、鹵化銣、鹵化銫、以及上述材料之組合。鹼金屬氟化物的範例包括氟化鋰、氟化鈉、氟化鉀、氟化銣、氟化銫及上述材料之組合。鹼金屬氯化物的範例包括:氯化鋰、氯化鈉、氯化鉀、氯化銣、氯化銫及上述材料之組合。
在多個實施例中,一或多種金屬鹵化物是以足以移除金屬氧化物層305的量接觸金屬表面302。例如,一或多種金屬鹵化物可蝕刻金屬表面302頂上的金屬氧化物層305,而形成暴露的金屬表面308,如圖3B所示。在多個實施例中,使用足以移除金屬氧化物層305的一或多種金屬鹵化物的量在適合反應的條件下執行金屬表面302與一或多種金屬鹵化物的接觸。在多個實施例中,使金屬表面302接觸一或多種金屬鹵化物是在如下所述之第一溫度執行:約攝氏300度至約攝氏400度、或約攝氏325度至約攝氏375度、或約攝氏325度、約攝氏350度、或約攝氏375度。在多個實施例中,使金屬表面302接觸一或多種金屬鹵化物是在下述量的壓力下執行:1至15托、約1至約15托、約5托、約10托、或約15托。在多個實施例中,使金屬表面302接觸一或多種金屬鹵化物執行達下述時間:約5至約20分鐘,諸如約10分鐘至約15分鐘。在多個實施例中,使金屬表面接觸一種或多種金屬鹵化物執行達5至20分鐘。金屬鹵化物的範例包括:金屬氟化物、金屬氯化物、金屬溴化物、金屬碘化物及上述材料的組合。根據本發明使用的適合的一或多種金屬氯化物的非限制性範例包括WClx、NbClx、RuClx、MoClx及上述材料之組合,其中x是整數或數字。
在多個實施例中,使金屬表面302接觸一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物)是在真空下執行,而使得氧無法抑制該反應或無法促進金屬表面302頂上額外的金屬氧化物材料生長。在多個實施例中,使金屬表面302接觸一或多種金屬鹵化物(例如金屬氯化物或金屬氟化物)是在諸如圖1之處理腔室的腔室中進行。圖1的處理腔室可以是無氧的。
適合根據本案揭露內容使用的金屬氯化物包括適合充分移除金屬表面302頂上的金屬氧化物層305以形成暴露的金屬表面308的任何金屬氯化物。根據本案揭露內容使用的適合的一或多種鹼金屬氯化物的非限制性範例包括WClx、NbClx、RuClx、MoClx或前述材料之組合,其中x是整數或數字。在多個實施例中,氯化鎢(WClx)(其中x是整數,例如大於1)是以氣態形式提供。在多個實施例中,WClx是適合的反應物(其中x是整數,例如2、4、5、6、……)。在一個實施例中,WClx是WCl6(六氯化鎢),其中x是整數6。在一些實施例中,前驅物氣體包括WCl5或WCl6。在多個實施例中,RuClx適用於本文,其中X是2或3的整數,該RuClx例如為氯化釕(III)或氯化釕(RuCl2)。在多個實施例中,諸如NbClx(x=5、4)的氯化鈮適用於本文。在多個實施例中,適用於本文的金屬氯化物可以以氣態形式提供,例如適於在腔室(例如圖1的處理腔室)中輸送 到基板的前驅物氣體。在多個實施例中,圖1的處理腔室是無氧腔室。
金屬氯化物與金屬表面302反應的反應式的一個範例如下所示:MOx+WClx加熱→WCly↑+MClz↑+O2↑在上述反應中,氣相WCl蝕刻掉原生氧化物且在表面上留下純金屬,而形成暴露的金屬表面。
金屬氯化物與金屬表面302反應的反應式的另一個範例如下所示: MOx+WClx↑+H2加熱→W↓+MClx↑+H2O↑上述反應中,將氫氣與WClx一起加入。結果,移除了天然氧化物。其他反應可適用於根據本發明的用途,包括在暴露的金屬表面區域上沉積額外的諸如鎢(W)之金屬之層的反應。
方法200在220繼續,並且如圖3C所描繪,在介電質表面304頂上生長或沉積自組裝單層306,例如基於有機矽烷的自組裝單層。在多個實施例中,可挑選自組裝單層306以在大於約攝氏50度(例如約攝氏100度至約攝氏500度)的第一溫度下呈熱穩定。藉由選擇在第一溫度下熱穩定的自組裝單層306,可在低於攝氏300度(諸如約攝氏100度至約攝氏200度)的溫度藉由化學氣相沉積(CVD)或原子層沉積(ALD)製程執行自組裝單層306的沉積,並且不會分解該自組裝單層306。
在多個實施例中,在介電質表面304頂上生長或沉積自組裝單層306(諸如基於有機矽烷的自組裝單層)包括:使介電質表面304接觸有機矽烷。在多個實施例中,有機矽烷是氣態形式,並且在真空下於腔室中輸送。適合的有機矽烷具有長的烷基鏈,以形成緊密、無缺陷、熱穩定、且化學惰性的阻障物,該阻障物能在稍後階段乾淨地移除。適合的有機矽烷可包含C-8至C-30烷基鏈,包括具有C-8至多達C-30烷基鏈的所有相應的同系物(homologue)。示範性的適合的有機矽烷包括(但不限於)十八烷基三氯矽烷(ODTS)、三甲氧基(十八烷基)矽烷(ODTMS)、氯(二甲基)十八烷基矽烷(CDODS)、或三氯(1H,1H,2H,2H-全氟辛基)矽烷(PFTS)。選擇有機矽烷分子的上述標準的其中一項可以是自組裝單層的熱穩定性。在多個實施例中,選擇在後續沉積的層310的沉積溫度下熱穩定的自組裝單層避免了在隨後沉積的層的沉積溫度下自組裝單層306分解。例如,ODTS在二氧化矽(SiO2)上的熱穩定性至少多達攝氏500度。因此,在透過ALD製程沉積層310期間ODTS自組裝單層不會分解。因此,SAM的熱穩定性擴展了溫度相容性的極限。在多個實施例中,生長基於有機矽烷的自組裝單層是下述量的壓力下執行:10至250托、100至350托、或250至350托。
在一些實施例中,適合的有機胺基矽烷的非限制性範例可包括甲矽烷胺(silylamine)材料,包括美 國專利申請號第15/446,816中描述的那些材料,該專利申請案之名稱為「具有間歇性空氣-水暴露的自組裝單層阻障」,由Kaufman-Osborn等人所發明。
在一些實施例中,適合用作本文SAM前驅物的甲矽烷基胺材料的非限制性範例包括:三(二甲胺基)甲基矽烷、三(二甲胺基)乙基矽烷、三(二甲胺基)丙基矽烷、三(二甲胺基)丁基矽烷、三(二甲胺基)戊基矽烷、三(二甲胺基)己基矽烷、三(二甲胺基)庚基矽烷、三(二甲胺基)辛基矽烷、三(二甲胺基)壬基矽烷、三(二甲胺基)癸基矽烷、三(二甲胺基)十一烷基矽烷、三(二甲胺基)十二烷基矽烷、三(二甲胺基)十三烷基矽烷、三(二甲胺基)十四烷基矽烷、三(二甲胺基)十五烷基矽烷、三(二甲胺基)十六烷基矽烷、三(二甲胺基)十七烷基矽烷、三(二甲胺基)十八烷基矽烷、三(二甲胺基)十九烷基矽烷、及上述材料之組合。
在一些實施例中,用於本文的SAM分子的非限制性範例包括:二甲胺基三甲基矽烷,以及具有以下化學式的化學品:

或是
Figure 108128544-A0305-02-0016-2
,及上述材料之組合。
在一些實施例中,基於有機矽烷的自組裝單層以氣體前驅物形式提供,並且可包括例如一有機矽烷濃度,該濃度足以在介電質表面304上形成單層,足以阻止層310沉積在介電質表面上。在多個實施例中,具有暴露的金屬表面308和介電質表面304的基板300接觸包含有機矽烷的氣態前驅物材料達約2至約3小時,而在介電質表面304頂上形成自組裝單層306。有機矽烷分子具有對介電質表面304的化學親合力(例如,有反應性及選擇性)。因此,自組裝單層306將僅會在介電質表面304上形成而不會在暴露的金屬表面308上形成。在多個實施例中,在沉積自組裝單層306之後,基板300停留或維持在真空下,以移除任何未吸收的有機矽烷分子。
接著,在230,且如圖3D中所描繪,顯示在基板300之暴露的金屬表面308頂上選擇性地沉積層310,其中自組裝單層306(諸如基於有機矽烷的自組裝單層)抑制介電質表面304頂上的層310的沉積。圖3D顯示了層310選擇性地沉積在基板300的暴露的金屬表面308頂上。在一些實施例中,透過任何適合的原子層沉積製程或化學層沉積進行層的沉積。介電質表面304頂上 自組裝單層306的存在抑制了在介電質表面304上層310的形成。在多個實施例中,自組裝單層306的熱穩定性防止自組裝單層306在層310之沉積溫度(例如,低於約攝氏300度)下的分解。層310可包括適合用於半導體元件製造的任何材料。例如,在一些實施例中,材料可以是第二低k材料或者是含矽材料,例如,諸如氧化矽(SiO2)。
接著,且如圖3E所描繪,處理基板300,以從介電質表面304頂上移除自組裝單層306。例如,基板300可以與遠端電漿接觸,而從介電質表面304頂上移除自組裝單層306。在一些實施例中,其他移除製程可包括使基板與水蒸氣電漿接觸,以從介電質表面304頂上移除自組裝單層306。在一些實施例中,可將基板300加熱到大於約攝氏500度(例如約攝氏500度至約攝氏1000度)的溫度,以從介電質表面304頂上移除自組裝單層306。實施例可包括,將基板加熱至高於攝氏500度的溫度。在移除自組裝單層306之後,方法200結束,且可根據需求使基板歷經進一步的處理,以完成半導體元件,諸如場效電晶體(FET)、鰭式場效電晶體(FinFET)、快閃記憶體元件、3D FINFET元件、或類似物。
圖4描繪了根據本案揭露內容的一些實施例的調節具有金屬表面和介電質表面的基板的方法的流程圖。在多個實施例中,提供一種調節具有金屬表面和介電質表面的基板的方法。在多個實施例中,該方法可包括使 金屬表面接觸一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物),而形成暴露的金屬表面,其中該暴露的金屬表面抑制該表面上基於有機矽烷的自組裝單層的沉積。在一些實施例中,使金屬表面接觸一或多種金屬鹵化物(諸如金屬氯化物或金屬氟化物)是在約攝氏300度至約攝氏400度的第一溫度下、於1至15托的壓力下進行達5至20分鐘的持續時間。在多個實施例中,金屬氯化物是包含WClx、NbClx、RuClx、MoClx或上述材料之組合的氣體,其中x是整數或數字。在其他實施例中,使金屬表面接觸一或多種金屬氯化物、金屬氟化物、或上述材料之組合是在上述任何條件下執行。在多個實施例中,該一或多種金屬鹵化物是包含WClx、NbClx、RuClx、MoClx或上述材料之組合的金屬氯化物氣體,其中x是整數或數字。
圖1描繪了可用於實行如本文所討論的本案揭露內容之實施例的那種類型的說明性設備的示意圖。設備100可包括控制器150和處理腔室102,該處理腔室102具有排氣系統120,用於從處理腔室102的內部空間105移除多餘的處理氣體、處理副產物、或類似物。示範性處理腔室可包括許多種處理腔室之任一者,該等處理腔室組裝成用於原子層沉積(ALD)或化學氣相沉積(CVD),該等處理腔室可自美國加州Santa Clara的應用材料公司購得。可類似地使用來自其他製造商的其他適合的處理腔室。
