Description

半導體裝置及其製造方法
本發明係有關於半導體裝置及其製造方法,特別有關於間隙子於應變矽中的半導體裝置及其製造方法。
半導體積體電路(IC)工業已經歷快速成長。體積體電路材料與設計的技術進步已造就數個IC世代,相較於前一世代,各世代具有更小且更複雜的電路。然而,這些進步以增加了IC的製程和製造的複雜度,並且為了實現這些技術進步,需要相似的研發於IC製程和製造。在積體電路演化的方向上,功能性的密度(亦即每晶片區域中內連線元件的數目)已逐漸地增加,隨著幾何尺寸(亦即使用製造技術所能創造的最小元件(或線))降低。此微縮化一般所提供的益處為增加製造效率及降低相關的成本。此微縮化亦造成相對地高功率散失值,可藉由使用低高功率散失裝置例如互補式金屬-氧化-半導體(CMOS)裝置解決。
於半導體製造製程中,間隙子可形成於一閘極堆疊的側壁上。上述間隙子可藉由以下的方法形成,包括沉積一適當的間隙子材料,及蝕刻該材料以形成所欲的間隙子輪廓。然而,傳統的形成間隙子的方法會留下不想要的間隙子材料殘留。
本發明之實施例提供一種半導體裝置的製造方法。上述方法包括:提供一矽基底具有一淺溝槽隔離物形成於其上;形成一閘極堆疊於該矽基底之上;形成虛置間隙子於該閘極堆疊的側壁上;形成一凹陷區於該矽基底中,其中該凹陷區為夾置於該閘極堆疊與該淺溝槽隔離物之間;磊晶成長一半導體材料於該凹陷區之內,其中該半導體材料係相異於該矽基底;移除該虛置間隙子;形成一第一氧化矽層於該閘極堆疊和該半導體材料之上;形成一氮化矽層於該第一氧化矽層之上;形成一第二氧化矽層於該氮化矽層之上;實施一第一乾蝕刻製程以移除一部分的該第二氧化矽層;實施一第二乾蝕刻製程以移除一部分的該氮化矽層;以及實施一第三乾蝕刻製程以移除一部分的該第一氧化矽層,藉此形成閘極間隙子於該閘極堆疊的側壁上,其中各閘極間隙子包括一殘留部分的該第一氧化矽層、該氮化矽層、及該第二氧化矽層。
本發明之實施例另提供一種半導體裝置的製造方法。上述方法包括:形成一閘極堆疊於一矽基底之上;形成虛置間隙子於該閘極堆疊的側壁上;等向性地蝕刻該矽基底以形成凹陷區於該閘極堆疊之一側;形成一半導體材料於該些凹陷區之內,其中該半導體材料係相異於該矽基底;移除該些虛置間隙子;形成複數個閘極間隙子層,其具有氧化物-氮化物-氧化物配置於該閘極堆疊與該半導體材料上;以及蝕刻該些間隙子層以形成閘極間隙子於該閘極堆疊的側壁上。
本發明之實施例又提供一半導體裝置。上述半導體裝置包括:一矽基底具有一矽區域、多個應變半導體材料區域、及一淺溝槽隔離物區域,其中該些應變半導體材料區域之一係夾置於該矽區域和該淺溝槽隔離物區域之間,以及其中該些應變半導體材料區域包括一等向性輪廓;以及一電晶體包括:一閘極堆疊於該矽區域上;多個間隙子形成於該閘極堆疊的側壁上,其中各間隙子包括一氮化層夾置於一第一氧化層和一第二氧化層之間;以及輕摻雜源極/汲極(LDD)區各形成於該矽區域的一部分位於該間隙子下方以及形成於應變半導體材料區域的一部分。

該半導體元件200可更包括一隔離結構204供基底中的主動區域206和208間絕緣。隔離結構204包括一介電材料及可由氧化矽、氮化矽、氮氧化矽、氟摻雜矽酸鹽(FSG)及/或公知的介電材料而形成。上述主動區域206和208可配置一N-型金屬-氧化-半導體電晶體裝置(簡稱為NMOS),或一P-型金屬-氧化-半導體電晶體裝置 (簡稱為PMOS)。
該半導體元件200可包括一閘極堆疊210形成於主動區域208之上。該閘極堆疊210可包括一界面層(未繪示)形成於該基底202之上。該界面層可包括氧化矽(SiO2 )或氮氧化矽(SiON)具有厚度約5到10埃(Å)。閘極堆疊210可更包括一高介電常數介電層212形成於該基底202之上。該高介電常數介電層212可包括氧化鉿(HfOx )。另擇一地,該高介電常數介電層212可選擇性地包括其他高介電常數介電材,例如LaO、AlO、ZrO、TiO、Ta2 O5 、SrTiO3 (STO)、BaTiO3 (BTO)、BaZrO、HfZrO、HfLaO、HfSiO、LaSiO、AlSiO、HfTaO、HfTiO、(Ba,Sr)TiO3 (BST)、Al2 O3 、Si3 N4 、氮氧化矽、或其他適合的材料。該高介電常數介電層212可包含一厚度範圍介於約10到40埃(Å)。高介電常數介電層212可由原子層沉積法(ALD)或其他適合的技術形成。
閘極堆疊210可更包括一金屬層213形成於高介電常數介電層212之上。該閘極堆疊210可包括任一金屬材料適用於形成金屬閘極或其一部分,包括低功函數層、襯墊層、界面層、晶種層、黏結層、阻障層等。例如,該金屬層可包括TiN、TaN、ZrN、HfN、VN、NbN、CrN、MoN、WN、TiAl、TiAlN、或其任意組合。該金屬層213可藉由可由ALD、物理氣相沉積法(PVD或濺鍍)、化氣相沉積法(CVD),或其他適合的技術形成。該閘極堆疊210可更包括一主動材料層214形成於該金屬層213之上。該主動材料層214可為一金屬層或者可包括Al、 Cu、W、Ti、Ta、Cr、V、Nb、Zr、Hf、Mo、Ni、Co、或其任意組合。另擇一地,該主動材料層214可藉由各種沉積技術形成,例如PVD、CVD、ALD、電鍍、或其他適合的技術。
該閘極堆疊210亦可包括一硬遮罩層216形成於該主動材料層214之上。該硬遮罩層216可使用於圖案化底下層,且可包括一介電材料例如氧化矽、氮化矽、氮氧化矽、或碳化矽。於本實施例中,該硬遮罩層216包括氮化矽。虛置間隙子218亦可形成於閘極堆疊210之任一側上。該虛置間隙子218可包括介電材料例如氮化矽或氧化矽。於本實施例中,該虛置間隙子218包括氧化矽。該虛置間隙子218可被形成,藉由沉積虛置間隙子層於該閘極堆疊210與矽基底202上,接著施以一乾蝕刻製程於該虛置間隙子層。
繼續進行該製造方法100的步驟區塊120在其中形成一凹陷區域於該基底中,其中該凹陷區域夾置於該閘極堆疊與該淺溝槽隔離物之間。請參閱第2B圖,可實施一蝕刻製程310於該基底202以形成凹陷區域220和222。於本實施例中,該蝕刻製程310可包括一蝕刻製程其形成一等方向性的輪廓。該蝕刻製程310可包括一乾蝕刻製程使用電漿氣體或一濕蝕刻製程使用酸。例如,該蝕刻製程310可使用HBr電漿氣體做為蝕刻劑。再者,於本實施例中,該蝕刻製程310可調整一偏壓於該電漿氧體以達到所望的輪廓於凹陷區域220和222中,其包括一等方向性的輪廓如本實施例的第2B圖所示。於其他 的實施例中,可使用一濕蝕刻製程,其包括HF酸做為蝕刻劑,以形成等方向性的輪廓於凹陷區域220和222中。於其他的實施例中,可實行結合乾式及濕式的蝕刻製程以形成等方向性的輪廓。如同先前所述,該淺溝槽隔離結構(STI)204可包括介電材料而該基底202包括矽材料,淺溝槽隔離結構204的介電材料和基底202的矽材料之間可具有蝕刻選擇率,使得蝕刻製程310不會將淺溝槽隔離結構204蝕刻掉。因此,當該閘極210位於次鄰於淺溝槽隔離結構204時,蝕刻製程310可停止或中斷於淺溝槽隔離結構204,使得淺溝槽隔離結構204形成該於凹陷區域222的邊界。當後續地形成側壁或閘極間隙子時,此可能導致發生殘留物移除的問題,此後將進一步討論。
繼續進行製造方法100的步驟區塊130在其中磊晶成長半導體材料於該凹陷區域中。請參閱第2C圖,可將半導體材料230和232相對地形成於凹陷區域220和222中,藉由一選擇性磊晶成長(SEG)製程315或其他適合的磊晶技術製程。該選擇性磊晶成長製程315可使用一特殊的CVD製程。例如,該特殊的CVD製程可實行於低的沉積速率或低的基底溫度。另擇一地,可使用ALD製程做為選擇性磊晶成長製程315。半導體材料230和232可為相異於矽基底202的材料。藉由完成此創造應變於半導體材料230和232與矽基底202,使得可提升主動區域208中的載子遷移率,其可允許較大的通道電流而不增加閘極電壓。因此,該半導體材料230和232可被稱 為“應變”半導體材料,以及凹陷區域222中矽基底202與半導體材料232之間的界面可被稱為“應變”界面。本實施例的先進之處在於因應變結構而提升載子遷移率。額外地,該應變結構升起於該矽基底202上方。於一實施例中,該主動區域208可為一PMOS元件,以及該半導體材料230和232可包括矽鍺(SiGe)。於另一實施例中,該主動區域208可為一NMOS元件,以及該半導體材料230和232可包括碳化矽(SiC)。然而,已觀察到該選擇性磊晶成長製程315可能無法成長半導體材料232於介電材料例如淺溝槽隔離結構204上,當半導體材料232典型地使用選擇性磊晶成長製程315成長於一晶體面例如矽基底202。其結果為,形成於該凹陷區域222中的半導體材料232可具有一傾斜的表面,如第2C圖所示。
請參閱第2D圖,可藉由蝕刻製程移除該虛置間隙子218。在蝕刻完該虛置間隙子218之後,可形成輕摻雜源極/汲極(簡稱為LDD)區域235於矽基底202位於閘極堆疊210之一側,藉由本技術領域所公知的離子植入法或擴散製程。於一實施例中,該主動區域208可為一PMOS元件,且P-型摻雜物例如硼可植入於該PMOS元件208中。於另一實施例中,該主動區域208可為一NMOS元件,且N-型摻雜物例如磷或砷可植入於該NMOS元件208中。如第2D圖所示,一部分的LDD區域235可形成於矽基底202,另一部分的LDD區域235可形成於半導體材料230和232相對於凹陷區域220和222中。
繼續進行製造方法100的步驟區塊140在其中形成 第一氧化矽層於該閘極堆疊和該半導體材料之上。請參閱第2E圖,可藉由CVD、ALD、或其他適當的技術,形成一間隙子層240於矽基底202和閘極堆疊210之上。該間隙子層240可包括一氧化物材料例如氧化矽。該間隙子層240可包含一厚度範圍大抵介於30埃至200埃。
繼續進行製造方法100的步驟區塊150在其中形成一氮化矽層於該第一氧化矽層之上。請參閱第2F圖,可藉由CVD、ALD、或其他適當的技術,形成一間隙子層250於間隙子層240之上。該間隙子層250可包括一氮化物材料例如氮化矽。該間隙子層250可包含一厚度範圍大抵介於30埃至200埃。
繼續進行製造方法100的步驟區塊160在其中形成一第二氧化矽層於該氮化矽間隙層之上。請參閱第2G圖,可藉由本技術領域所公知的技術,例如CVD或ALD,形成一間隙子層260於間隙子層250之上。該間隙子層260可包括一氧化物材料例如氧化矽。該間隙子層260可包含一厚度範圍大抵介於100埃至1000埃。應注意的是,間隙子層260的厚度可分別地大於間隙子層240和250的厚度。有鑑於此,間隙子層260愈厚,可使其愈容易受控制且於後續的蝕刻製程中最佳化該側壁/閘極間隙子的臨界維度(critical dimension),將於以下內容中討論。
繼續進行製造方法100的步驟區塊170在其中實施一第一乾蝕刻製程以移除一部分的第二氧化矽層。請參閱第2H圖,可實施蝕刻製程320於間隙子層260。該蝕刻製程320可為一乾蝕刻製程且可包含一碳氟基電漿氣 體做為一蝕刻劑。該蝕刻製程320可移除位於該閘極堆疊210上方的一部分的該間隙子層260。該蝕刻製程320亦可移除位覆蓋半導體材料230和232分別於凹陷區域220和222中的一部分的該間隙子層260。因此,在蝕刻製程320之後,一殘留部分的間隙子層260可構成位於閘極堆疊210側壁上結構265。該結構265的厚度可藉由控制蝕刻製程320的蝕刻速率,並且以可藉由控制間隙子層260的初始地沉積步驟(於步驟區塊160中)。該結構265可用於保護位於其下方的間隙子層240和250的部分,以避免於之後的蝕刻製程中被蝕刻。該結構265亦可用於避免橋接效應。再者,由於在本實施例中,間隙子層260包括氧化物材料及間隙子層250包括氮化物材料,因此在間隙子層250和260之間可具有充分的蝕刻選擇率。因此,間隙子層250可作用為蝕刻製程320的蝕刻終止層。
繼續進行製造方法100的步驟區塊180在其中實施一第二乾蝕刻製程以移除一部分的氮化矽層。請參閱第2I圖,可實施蝕刻製程330於間隙子層250。該蝕刻製程330可為一乾蝕刻製程,移除掉未被結構265保護的間隙子層250的部分。因此,蝕刻製程330可移除位於閘極堆疊210上方的間隙子層250的部分。該蝕刻製程330亦可移除位覆蓋半導體材料230和232分別於凹陷區域220和222中的一部分的該間隙子層250。於本實施例中,該蝕刻製程330可為一乾蝕刻製程且可包含一氫-氟基電漿氣體做為一蝕刻劑。再者,由於在本實施例中, 間隙子層240包括氧化物材料及間隙子層250包括氮化物材料,因此在間隙子層240和250之間可具有充分的蝕刻選擇率。因此,間隙子層240可作用為蝕刻製程330的蝕刻終止層。
繼續進行製造方法100的步驟區塊190在其中實施一第三乾蝕刻製程以移除一部分的第一氧化矽層,由此形成閘極間隙子於閘極堆疊的側壁上。請參閱第2J圖,可實施蝕刻製程340於間隙子層240。該蝕刻製程340可為一乾蝕刻製程,移除掉未被結構265保護的間隙子層240的部分。因此,蝕刻製程340可移除位於閘極堆疊210上方的間隙子層240的部分。該蝕刻製程340亦可移除位覆蓋半導體材料230和232分別於凹陷區域220和222中的一部分的該間隙子層240。於本實施例中,該蝕刻製程340可為一乾蝕刻製程且可包含一碳氟基電漿氣體做為一蝕刻劑。該蝕刻製程340可實質地移除完位於凹陷區域222中的半導體材料232上的間隙子層240,使得在凹陷區域222中的半導體材料232的上面並無殘留。在實施蝕刻製程340之後,可形成間隙子275於閘極堆疊210的側壁上。該間隙子275可包括一殘留的部分的間隙子層250夾置於該結構265與殘留的部分的間隙子層240之間。
由此可觀察到,若側壁間隙子已經形成,藉由形成一主要的間隙子材料於該基底和該閘極堆疊上,並藉由實施乾蝕刻製程於該間隙子材料,可導致間隙子殘留的問題。以傳統的方法,形成一主要間隙子材料層於基底 上,僅以一部分的間隙子材料填入該凹陷區域中。該蝕刻製程,實施用以形成間隙子且移除位於該凹陷區域中間隙子材料,並非有效率的,因此導致留下間隙子材料殘留於該凹陷區域中的應變結構上。該材料殘留對於後續的製程具有不利的效果,例如一離子植入製程以形成源極/汲極區以及一矽化製程以形成矽結構於源極/汲極區域及其他主動區域上。相較之下,本實施例可藉由數種蝕刻製程完全地移除位於該凹陷區域222中半導體材料232上的各種間隙子層。因此,本實施例之一優點為不會有不想要的間隙子材料殘留存在於半導體元件200中。
應注意的是,可藉由額外的步驟繼續進行製造方法100,以完成製造該半導體元件200。例如,藉由離子植入法或擴散適當的N-型或P-型摻雜物,形成重摻雜源極/汲極區於該基底202中,於該閘極堆疊210之一側。該重摻雜源極/汲極區可實質地對準於結構265的外側側邊。藉由矽化製程形成矽化物結構於源極/汲極區域及多晶矽層上。一接觸蝕刻終止層(CESL)可形成於該基底上。一層間介電(ILD)層可形成於CESL上。此外,多個接觸與內連線可形成以建構半導體元件200的電性連接。
綜上所述,在此所揭露的方法和裝置的優點為在一半導體裝置的矽基底中形成多個凹陷區域,以及以應變半導體材料填入該些凹陷區域中,以創造出應變界面於該基地和半導體材料之間。上述所揭露的亦包括間隙子具有多層的配置且藉由實施最佳化的乾蝕刻製程形成。 藉由這麼做,本實施例提供多個優於習知技術的優點。本實施例的優點之一在於該應變界面,其位於該凹陷區域中的半導體材料與該矽基底之間,可提升半導體裝置的載子遷移率。該載子遷移率允許較大的通道電流而無須增加閘極電壓。本實施例的另一優點在於多層配置的間隙子以及最佳化的蝕刻步驟以克服間隙子殘留問題,其可能出現在習知技術中。本實施例的再一優點在於此處所揭露的方法可相容於CMOS製程流程且可容易地實行。應注意的是,此處所揭露的各不同的實施例提供不同的優點,並且無特定的優點是必需被所有實施例所要求。
本發明雖以各種實施例揭露如上,然其並非用以限定本發明的範圍,任何所屬技術領域中具有通常知識者,在不脫離本發明之精神和範圍內,當可做些許的更動與潤飾,因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。
