Abstract
本發明揭露一種製作半導體元件的方法。首先提供一基底,該基底包含一第一區域以及一第二區域,然後形成一第一鰭狀結構於第一區域上,去除部分第一鰭狀結構以形成一第一凹槽,形成一介電層於第一凹槽內,其中該介電層包含氮碳氧化矽(SiOCN),之後再平坦化介電層以形成一第一單擴散隔離結構。
Description
本發明是關於一種製作半導體元件的方法,尤指一種分隔鰭狀結構以形成單擴散隔離(single diffusion break,SDB)結構的方法。
近年來,隨著場效電晶體(field effect transistors,FETs)元件尺寸持續地縮小,習知平面式(planar)場效電晶體元件之發展已面臨製程上之極限。為了克服製程限制,以非平面(non-planar)之場效電晶體元件,例如鰭狀場效電晶體(fin field effect transistor,Fin FET)元件來取代平面電晶體元件已成為目前之主流發展趨勢。由於鰭狀場效電晶體元件的立體結構可增加閘極與鰭狀結構的接觸面積,因此,可進一步增加閘極對於載子通道區域的控制,從而降低小尺寸元件面臨的汲極引發能帶降低(drain induced barrier lowering,DIBL)效應,並可以抑制短通道效應(short channel effect,SCE)。再者,由於鰭狀場效電晶體
元件在同樣的閘極長度下會具有更寬的通道寬度,因而可獲得加倍的汲極驅動電流。甚而,電晶體元件的臨界電壓(threshold voltage)亦可藉由調整閘極的功函數而加以調控。
在現行的鰭狀場效電晶體元件製程中,鰭狀結構周圍形成淺溝隔離後通常會以蝕刻方式去除部分鰭狀結構與淺溝隔離形成凹槽,然後填入絕緣物以形成單擴散隔離結構並將鰭狀結構分隔為兩部分。然而現今單擴散隔離結構與金屬閘極的製程在搭配上仍存在許多問題,因此如何改良現有鰭狀場效電晶體製程與架構即為現今一重要課題。
本發明一實施例揭露一種製作半導體元件的方法。首先提供一基底,該基底包含一第一區域以及一第二區域,然後形成一第一鰭狀結構於第一區域上,去除部分第一鰭狀結構以形成一第一凹槽,形成一介電層於第一凹槽內,其中該介電層包含氮碳氧化矽(SiOCN),之後再平坦化介電層以形成一第一單擴散隔離結構。
本發明另一實施例揭露一種半導體元件,其主要包含:一基底,該基底包含一第一區域以及一第二區域;一第一鰭狀結構設於第一區域上;一第一單擴散隔離結構設於第一鰭狀結構上並將該第一鰭狀結構分隔為第一部分以及第二部分,其中第一單擴散隔離結構包含氮碳氧化矽(SiOCN)。

第1圖為本發明一實施例之一半導體元件之上視圖。
第2圖至第7圖為本發明一實施例製作半導體元件之方法示意圖。
請參照第1圖至第2圖,其中第1圖為本發明一實施例製作一半導體元件之上視圖,第2圖左半部為第1圖中沿著切線AA'之剖面示意圖,第2圖右半部則為第1圖中沿著切線BB'之剖面示意圖。如第1圖至第2圖所示,首先提供一基底12,例如一矽基底或矽覆絕緣(SOI)基板,並於基底12上定義一第一電晶體區例如一NMOS區域14以及一第二電晶體區例如一PMOS區域16。然後分別於NMOS區域以及PMOS區域形成至少一鰭狀結構18於基底12上。在本實施例中,設於各電晶體區的鰭狀結構18雖以四根為例,但所設置的鰭狀結構18數量均可依據產品需求任意調整,並不侷限於此。
依據本發明之較佳實施例,鰭狀結構18較佳透過側壁圖案轉移(sidewall image transfer,SIT)等技術製得,其程序大致包括:提供一佈局圖案至電腦系統,並經過適當地運算以將相對應之圖案定義於光罩中。後續可透過光微影及蝕刻製程,以形成多個等距且等寬之圖案化犧牲層於基底上,使其個別外觀呈現條狀。之後依序施行沉積及蝕刻製程,以於圖案化犧牲層之各側壁形成側壁子。繼以去除圖案化犧
牲層,並在側壁子的覆蓋下施行蝕刻製程,使得側壁子所構成之圖案被轉移至基底內,再伴隨鰭狀結構切割製程(fin cut)而獲得所需的圖案化結構,例如條狀圖案化鰭狀結構。
除此之外,鰭狀結構18之形成方式又可包含先形成一圖案化遮罩(圖未示)於基底12上,再經過一蝕刻製程,將圖案化遮罩之圖案轉移至基底12中以形成鰭狀結構18。另外,鰭狀結構18之形成方式也可以先形成一圖案化硬遮罩層(圖未示)於基底12上,並利用磊晶製程於暴露出於圖案化硬遮罩層之基底12上成長出例如包含矽鍺的半導體層,而此半導體層即可作為相對應的鰭狀結構18。這些形成鰭狀結構18的實施例均屬本發明所涵蓋的範圍。值得注意的是,在形成鰭狀結構18之後NMOS區域14以及PMOS區域16的鰭狀結構18表面可設有一由氧化矽所構成襯墊層22。
然後形成一淺溝隔離(shallow trench isolation,STI)20環繞鰭狀結構18。在本實施例中,形成淺溝隔離20的方式可先利用一可流動式化學氣相沉積(flowable chemical vapor deposition,FCVD)製程形成一氧化矽層於基底12上並完全覆蓋鰭狀結構18。接著利用化學機械研磨(chemical mechanical polishing,CMP)製程並搭配蝕刻製程去除部分氧化矽層,使剩餘的氧化矽層低於鰭狀結構18表面以形成淺溝隔離20。
如第2圖所示,接著利用一圖案化遮罩(圖未示)為遮罩進行一蝕刻製程,依序去除部分襯墊層22以及部分鰭狀結構18以形成凹槽24,其中各凹槽24較佳將位於NMOS區域14以及PMOS區域16的各鰭狀
結構18分隔為兩部分,包括位於凹槽24左側的部分26以及位於凹槽24右側的部分28。
隨後如第3圖所示,先利用氧化方式形成另一由氧化矽所構成的襯墊層30於NMOS區域14以及PMOS區域16的各凹槽24內使襯墊層30覆蓋凹槽24兩側的側壁以及凹槽底部並直接接觸設於鰭狀結構18上表面的襯墊層22,再形成一介電層32於各凹槽24內並填滿各凹槽24。接著進行一平坦化製程,例如利用化學機械研磨(chemical mechanical polishing,CMP)以及/或蝕刻製程去除部分介電層32使剩餘介電層32上表面約略切齊或略高於鰭狀結構18上表面,以於NMOS區域14以及PMOS區域16分別形成單擴散隔離結構34、36。
如第1圖中所示,設於NMOS區域14以及PMOS區域16的各鰭狀結構18係沿著一第一方向(例如X方向)延伸而各單擴散隔離結構34、36則是沿著一第二方向(例如Y方向)延伸,其中第一方向係垂直第二方向。
另外需注意的是,本實施例中介電層32以及襯墊層30較佳包含不同材料,例如襯墊層30較佳由氧化矽所構成而介電層32則較佳由氮碳氧化矽(silicon oxycarbonitride,SiOCN)所構成。更具體而言,本實施例由氮碳氧化矽所構成的單擴散隔離結構34、36較佳為一具有低應力的單擴散隔離結構,其中氧氣於氮碳氧化矽內之濃度比例較佳介於30%至60%且各單擴散隔離結構34、36的應力較佳介於100MPa至-500Mpa或最佳約0MPa。相較於習知無論是以氧化矽或氮化矽材料所
製備的單擴散隔離結構,本實施例利用這種具有低應力材料所形成的單擴散隔離結構可有效提升各電晶體區在電流開啟以及關閉方面的整體效能。
然後如第4圖所示,可利用離子佈植製程分別於NMOS區域14以及PMOS區域16的鰭狀結構18內形成後續電晶體所需的深井區或井區,再進行一清洗製程,例如利用稀釋氫氟酸(diluted hydrofluoric acid,dHF)完全去除原本設於鰭狀結構18上表面的襯墊層22、設於凹槽24側壁的部分襯墊層30甚至部分單擴散隔離結構34、36,藉此暴露出鰭狀結構18表面並使剩餘襯墊層30以及單擴散隔離結構34、36上表面略低於鰭狀結構18上表面,其中單擴散隔離結構34、36上表面又略高於剩餘襯墊層30上表面。
如5圖所示,接著於NMOS區域14以及PMOS區域16的鰭狀結構18上分別形成至少一閘極結構38、40或至少一虛置閘極。在本實施例中,閘極結構38、40的製作方式可依據製程需求以先閘極(gate first)製程、後閘極(gate last)製程之先高介電常數介電層(high-k first)製程以及後閘極製程之後高介電常數介電層(high-k last)製程等方式製作完成。以本實施例之後高介電常數介電層製程為例,可先依序形成一閘極介電層42或介質層、一由多晶矽所構成之閘極材料層44以及一選擇性硬遮罩於基底12或鰭狀結構18上,並利用一圖案化光阻(圖未示)當作遮罩進行一圖案轉移製程,以單次蝕刻或逐次蝕刻步驟,去除部分閘極材料層44以及部分閘極介電層42,然後剝除圖案化光阻,以於鰭狀結構18上形成由圖案化之閘極介電層42與圖案化之閘極材料層44所
構成的閘極結構38、40。
然後於各閘極結構38、40側壁分別形成至少一側壁子46,接著於側壁子46兩側的鰭狀結構18以及/或基底12中形成一源極/汲極區域48及/或磊晶層50,並選擇性於源極/汲極區域48及/或磊晶層50表面形成一金屬矽化物(圖未示)。在本實施例中,側壁子46可為單一側壁子或複合式側壁子,例如可細部包含一偏位側壁子以及一主側壁子。其中偏位側壁子與主側壁子可包含相同或不同材料,且兩者均可選自由氧化矽、氮化矽、氮氧化矽以及氮碳化矽所構成的群組。源極/汲極區域48以及磊晶層50可依據所置備電晶體的導電型式而包含不同摻質與不同材料,例如NMOS區域14的源極/汲極區域48可包含N型摻質且磊晶層50可包含磷化矽(silicon phosphide,SiP),而PMOS區域16的源極/汲極區域48可包含P型摻質且磊晶層50可包含例如鍺化矽(silicon germanium,SiGe)。
接著如第6圖所示,先形成一接觸洞蝕刻停止層52於鰭狀結構18表面以及閘極結構38、40上,再形成一層間介電層54於接觸洞蝕刻停止層52上。然後進行一平坦化製程,例如利用化學機械研磨製程去除部分層間介電層54以及部分接觸洞蝕刻停止層52並暴露出由多晶矽材料所構成的閘極材料層44,使閘極材料層44上表面與層間介電層54上表面齊平。
隨後進行一金屬閘極置換製程將各閘極結構38、40轉換為金屬閘極58、60。舉例來說,可先進行一選擇性之乾蝕刻或濕蝕刻製程,
例如利用氨水(ammonium hydroxide,NH4OH)或氫氧化四甲銨(Tetramethylammonium Hydroxide,TMAH)等蝕刻溶液來去除閘極結構38、40中的閘極材料層44甚至閘極介電層42,以於層間介電層54中形成凹槽56。
如第7圖所示,之後依序形成一選擇性介質層或閘極介電層62、一高介電常數介電層64、一功函數金屬層66以及一低阻抗金屬層68於各凹槽56內,然後進行一平坦化製程,例如利用CMP去除部分低阻抗金屬層68、部分功函數金屬層66與部分高介電常數介電層64以形成金屬閘極58、60。隨後可再去除部分低阻抗金屬層68、部分功函數金屬層66以及部分高介電常數介電層64以形成凹槽(圖未示),再填入一由例如氮化矽所構成的硬遮罩70於凹槽內並使硬遮罩70上表面切齊層間介電層54上表面。以本實施例利用後高介電常數介電層製程所製作的閘極結構為例,所形成的各金屬閘極58、60較佳包含一介質層或閘極介電層62、一U型的高介電常數介電層64、一U型的功函數金屬層66以及一低阻抗金屬層68。
在本實施例中,高介電常數介電層64包含介電常數大於4的介電材料,例如選自氧化鉿(hafnium oxide,HfO2)、矽酸鉿氧化合物(hafnium silicon oxide,HfSiO4)、矽酸鉿氮氧化合物(hafnium silicon oxynitride,HfSiON)、氧化鋁(aluminum oxide,Al2O3)、氧化鑭(lanthanum oxide,La2O3)、氧化鉭(tantalum oxide,Ta2O5)、氧化釔(yttrium oxide,Y2O3)、氧化鋯(zirconium oxide,ZrO2)、鈦酸鍶(strontium titanate oxide,SrTiO3)、矽酸鋯氧化合物(zirconium silicon oxide,
ZrSiO4)、鋯酸鉿(hafnium zirconium oxide,HfZrO4)、鍶鉍鉭氧化物(strontium bismuth tantalate,SrBi2Ta2O9,SBT)、鋯鈦酸鉛(lead zirconate titanate,PbZrxTi1-xO3,PZT)、鈦酸鋇鍶(barium strontium titanate,BaxSr1-xTiO3,BST)、或其組合所組成之群組。
功函數金屬層66較佳用以調整形成金屬閘極之功函數,使其適用於N型電晶體(NMOS)或P型電晶體(PMOS)。若電晶體為N型電晶體,功函數金屬層66可選用功函數為3.9電子伏特(eV)~4.3eV的金屬材料,如鋁化鈦(TiAl)、鋁化鋯(ZrAl)、鋁化鎢(WAl)、鋁化鉭(TaAl)、鋁化鉿(HfAl)或TiAlC(碳化鈦鋁)等,但不以此為限;若電晶體為P型電晶體,功函數金屬層66可選用功函數為4.8eV~5.2eV的金屬材料,如氮化鈦(TiN)、氮化鉭(TaN)或碳化鉭(TaC)等,但不以此為限。功函數金屬層66與低阻抗金屬層68之間可包含另一阻障層(圖未示),其中阻障層的材料可包含鈦(Ti)、氮化鈦(TiN)、鉭(Ta)、氮化鉭(TaN)等材料。低阻抗金屬層68則可選自銅(Cu)、鋁(Al)、鎢(W)、鈦鋁合金(TiAl)、鈷鎢磷化物(cobalt tungsten phosphide,CoWP)等低電阻材料或其組合。
之後可進行一圖案轉移製程,例如可利用一圖案化遮罩去除部分層間介電層54以及部分接觸洞蝕刻停止層52以形成複數個接觸洞(圖未示)暴露出下面的源極/汲極區域48。然後再於各接觸洞中填入所需的金屬材料,例如包含鈦(Ti)、氮化鈦(TiN)、鉭(Ta)、氮化鉭(TaN)等的阻障層材料以及選自鎢(W)、銅(Cu)、鋁(Al)、鈦鋁合金(TiAl)、鈷鎢磷化物(cobalt tungsten phosphide,CoWP)等低電阻材料或其組合的低阻抗金屬層。之後進行一平坦化製程,例如以化學機械研磨去除
部分金屬材料以分別形成接觸插塞72於各接觸洞內電連接源極/汲極區域48。至此即完成本發明較佳實施例之半導體元件的製作。
另外需注意的是,雖然上述實施例較佳同時於NMOS區域以及PMOS區域中形成單擴散隔離結構,但不侷限於此設計,依據本發明一實施例又可選擇依據前述製程僅於NMOS區域或PMOS區域形成單擴散隔離結構後再進行後續閘極結構以及金屬閘極置換製程,此變化型也屬本發明所涵蓋的範圍。
綜上所述,本發明主要於NMOS區域以及/或PMOS區域形成鰭狀結構之後將各電晶體區的各鰭狀結構分隔為兩部分,並同時於兩個電晶體區內所分隔的鰭狀結構之間填入相同介電材料形成單擴散隔離結構。依據本發明之較佳實施例,形成於NMOS區域以及PMOS區域的單擴散隔離結構較佳由氮碳氧化矽(SiOCN)所構成,其中氧氣於氮碳氧化矽內之濃度比例較佳介於30%至60%且各單擴散隔離結構34、36的應力較佳介於100MPa至-500MPa。相較於習知無論是以氧化矽或氮化矽材料所製備的單擴散隔離結構,本發明利用這種具有低應力材料所形成的單擴散隔離結構可有效提升各電晶體區在電流開啟以及關閉方面的整體效能。
以上所述僅為本發明之較佳實施例,凡依本發明申請專利範圍所做之均等變化與修飾,皆應屬本發明之涵蓋範圍。
