說明了形成和利用微電子結構(如包含應變源極/汲極結構的裝置結構)之方法及相關結構。那些方法/結構可能包括在包含矽之裝置的源極/汲極開口中形成一薄鍺化矽材料,其中多個錯位係形成在鍺化矽材料中,且接著在薄鍺化矽材料上形成一源極/汲極材料,其中錯位引起整個源極/汲極材料的源極/汲極錯位。本文之實施例致能應變通道裝置,其中源極/汲極結構可能在裝置之一通道區中引起一拉伸應變。
第1a-1e圖繪示形成微電子結構(例如,N通道金屬氧化物半導體應變矽電晶體結構)之實施例的圖示。在一實施例中,裝置100可能包含基板104(第1a圖,俯視圖)。在一實施例中,基板104可能包含矽、非矽材料、單晶矽材料、多晶矽材料、壓電材料、Ⅲ-V材料及/或其他機電基板材料之至少一者。在一實施例中,裝置100可能包含平面電晶體、多閘電晶體(如三閘及/或finFET電晶體)、及奈米線結構的一部分。
裝置100可能更包含閘極電極102,其可能包含電晶體閘極電極102(如N通道金屬氧化物半導體電晶體閘極電極)的一部分。裝置100可能更包含源極/汲極結構108。源極/汲極結構108可能包含矽鰭片結構,在一實施例中,其可能由介電材料106彼此分離。在一實施例中,介電材料106可能包含STI(矽溝槽隔離)材料。介電材料106可能提供在鰭片結構108與閘極電極102之間的隔離。在一實施例中,裝置100的通道部分可能設置於閘極電極102下方。
在一實施例中,可能從裝置100(第1b圖,俯視圖)的基板104移除源極/汲極結構/鰭片。在一實施例中,可能採用蝕刻程序109(例如,濕或乾蝕刻),其中移 除源極/汲極/鰭片結構108的矽,將開口110留在相鄰於STI的基板104中。在閘極電極下方之矽的通道部分仍然完整,即,它仍未由移除程序/蝕刻程序109蝕刻。第1c圖描繪裝置100的剖面圖,其中移除源極/汲極鰭片且在基板104的一部分中暴露開口110。通道區112係設置於閘極電極102下方,其中閘極介電層116係設置於閘極電極102與通道區112之間。間隔物材料116可能設置於閘極電極102上。
錯位成核層/材料118可能形成在開口110中(第1d圖,剖面)。在一實施例中,可能使用在源極/汲極區中的基板104上之開口110中的外延生長來選擇性地生長錯位成核層118。在一實施例中,錯位成核層118可能包含鍺化矽層118。可能生長錯位成核層118,使得複數個錯位可能形成在錯位成核層118中。在一實施例中,錯位成核層118可能包含約2至約50nm的厚度。
錯位成核層118可能產生淨應變,其包含拉伸應變。在一實施例中,相較於基板104,錯位成核層118的晶格常數可能不匹配(且可能有助於應力錯位形成)。在一實施例中,錯位成核層118可能包含比基板104之晶格常數大更多的晶格常數。例如,晶格常數對於鍺化矽合金而言可能包含在5.43與5.66Å之間,且對於矽基板而言可能包含5.43Å。在一實施例中,可能藉由外延生長來形成錯位成核層118作為在源極/汲極開口110之矽部分上的初始層。在一實施例中,源極/汲極開口可能包 含N通道金屬氧化物半導體源極/汲極開口110。
在一實施例中,當錯位成核層118包含鍺化矽材料時,鍺化矽可能包含在約百分之十至約百分之八十之間的鍺濃度。在另一實施例中,鍺化矽可能摻雜有磷和砷之至少一者。在一實施例中,磷可能包含在約1016cm-3與1021cm-3之間的濃度。在一實施例中,砷可能包含在約1016cm-3與1021cm-3之間的濃度。在一實施例中,錯位成核層118可能包含鍺化矽、磷、砷濃度,其實質上均勻地分佈於整個錯位成核層118。
在另一實施例中,錯位成核層118可能包含下部分,包含鍺化矽、磷、和砷濃度,其實質上均勻地分佈於錯位成核層118的下部分中,且可能包含上部分,實質上包含磷化矽濃度。在另一實施例中,錯位成核層118可能生長在開口110中作為未摻雜的鍺化矽材料,其可能隨後由離子植入和來自摻雜物來源的擴散摻雜之其一者摻雜。在另一實施例中,可能使用如氣源(GS)-MBE法的分子束磊晶法(MBE)來形成錯位成核層118。
在一實施例中,快速熱化學蒸氣沉積(RT-CVD)反應器或CVD反應器可能用以生長錯位成核層118。在一實施例中,用以生長錯位成核層118的程序可能包括使用矽烷、鍺、乙鍺烷、膦、及具有氫載體氣體的鹽酸。可能採用攝氏700度的溫度和20托的壓力。用於錯位成核層118生長程序的參數可能取決於特定應用而有所不同。在一實施例中,可能針對複數個缺陷之形成來最 佳化生長參數。在一實施例中,可能在基板104與錯位成核層118之間的介面形成/啟動大量的錯位/缺陷120。

在一實施例中,源極/汲極材料122中的錯位124可能繼續向上傳播到源極/汲極材料122的自由表面125。在一實施例中,設置於源極/汲極材料122中的多個錯位124可能使晶格不匹配的錯位成核層118所給予的應變在通道區112中從壓縮翻轉成拉伸應變。在一實施例中,來自每個錯位124的重疊應變場能克服可能存在於錯位成核層118(如鍺化矽層118)中的壓縮應力。在一實施例中,源極/汲極材料122可能沿著導電方向將通道區112上的拉伸應變分給裝置100(在實施例中,其可能包含電晶體裝置)。
在一實施例中,裝置100可能包含電路元件,如包括平面、三閘及奈米線電晶體結構的電晶體結構,及任何其他適當電路元件。例如,電路元件可能包含 用於在處理器晶粒中使用的邏輯電路。金屬化層和絕緣材料以及可能將金屬層/互連耦接至外部裝置的導電接點/凸塊可能包括在裝置100中。電晶體裝置。包括在裝置100中的元件類型可能根據特定應用而包含任何適當類型的電路元件。
第2圖描繪包含裝置結構200之實施例的剖面圖,其中裝置包含奈米線。在一實施例中,裝置200(如奈米線裝置200)可能包含設置於通道區212下方的基板204。錯位成核層218可能包含複數個缺陷/錯位220。源極/汲極材料222可能包含複數個缺陷/錯位224。閘極電極202可能設置於閘極介電質214上。奈米線材料203(如矽)可能設置於閘極介電質214下方。環繞式閘極介電質205可能設置於環繞式奈米線材料203下方。環繞式閘極電極207可能設置於環繞式閘極介電質205下方。通道區包含從來自源極/汲極材料222的錯位所引起的應變。
在一實施例中,實施例之裝置100可能與能夠在微電子裝置(例如,晶粒)與可能耦接至封裝結構的下一級元件(例如,電路板)之間提供電通訊的任何適當類型之封裝結構耦接。在另一實施例中,裝置可能與可能包含能夠在晶粒和與裝置層耦接之上積體電路(IC)封裝之間提供電通訊的任何適當類型之封裝結構耦接。
在本文之各種圖中所述之裝置可能包含例如矽邏輯晶粒或記憶體晶粒的一部分、或任何類型的適當微電子裝置/晶粒。在一些實施例中,實施例之裝置可能更 包含複數個晶粒,其可能依據特定實施例而堆疊於彼此上方。在一些情況下,裝置可能位於/附接於/嵌入於前側、後側之任一者上或在封裝結構之前和後側的一些組合上/中。在一實施例中,裝置可能部分地或完全地嵌入於封裝結構中。
本文之應變通道裝置的各種實施例能將應變從N通道金屬氧化物半導體源極/汲極區的源極/汲極區傳送至N通道金屬氧化物半導體通道區。透過在N通道金屬氧化物半導體源極/汲極區中使用錯位應變場來實現應變傳送。實現通道應變的一些習知技術方法已包含在通道區下方採用不匹配晶格常數材料的緩衝層,及在源極/汲極區中採用摻雜物。本文之實施例包括採用錯位成核層(如鍺化矽)以傳播重疊應變場,其在通道區中引起拉伸應變。由於生長僅發生在源極/汲極區內,因此如當與在習知技術中一樣利用緩衝層時所見,實施例避免效能降低至通道中。
