以下揭露內容提供用於實施所提供標的的不同特徵的許多不同實施例或實例。以下文描述之組件及佈置的特定實例,來簡化本揭露。這些組件以及佈置僅為實例且並不意欲為限制性的。另外,本揭露可在各種實例中重複附圖標號及/或字母。此重複是出於簡單及清晰的目的,除非另外指示,否則其自身並不指示所論述的各種實施例及/或設置之間的關係。
本揭露描述將局部互連結構佈線至電晶體裝置(例如鰭式場效電晶體(fin field effect transistor,finFET)裝置、雙閘極裝置、三閘極裝置、ω FET(omega FET)以及環繞式閘極(gate all round)裝置)的一或多個閘極端、一或多個汲極端及/或一或多個源極端。將局部互連結構佈線至閘極端、汲極端及/或源極端的其中一個益處是為減少互連層級中(例如,在一個MO互連層級中)的一或多個寄生電容。藉由使用局部互連結構佈線至這些端,互連層級中的互連件的長度尺寸可被縮短或最小化。此經縮短的互連件長度或最小的互連件長度減少存在於互連層級中的寄生電容,因此提高裝置效能。
圖1是根據一些實施例的反相器裝置100的電路表示的示意圖。反相器裝置100包含n型電晶體110及p型電晶體120。n型電晶體110及p型電晶體120的閘極端在輸入端112處彼此電性連接。n型電晶體110及p型電晶體120的汲極端在輸出端115處彼此電性連接。p型電晶體120的源極端電性連接至電源電壓130。電源電壓的實例可為0.5V、0.7V、1.2V、1.8V、2.4V、3.3V或5V。所屬領域中具通常知識者應理解可基於本文中的描述來使用其他電源電壓。n型電晶體110的源極端電性連接至接地140(例如0V)。輸入端112處的一個邏輯高電壓(例如電源電壓130)產生輸出端115處的一個邏輯低電壓(例如0V),反之亦然。閘極端在本文中亦稱作「閘極」。另外,源極端及汲極端在本文中亦稱作「源極/汲極」(S/D)或「源極/汲極端」(S/D端)。
圖2是根據一些實施例的另一反相器裝置200的電路表示的示意圖。反相器裝置200具有包含n型電晶體2100至n型電晶體2103及p型電晶體2200至p型電晶體2205的多閘極(multi-gate)電晶體結構。n型電晶體2100至n型電晶體2103彼此以並聯方式電性連接:n型電晶體2100至n型電晶體2103的汲極端彼此電性連接,n型電晶體2100至n型電晶體2103的源極端彼此電性連接,且n型電晶體2100至n型電晶體2103的閘極端彼此電性連接。類似地,p型電晶體2200至p型電晶體2205彼此以並聯方式電性連接:p型電晶體2200至p型電晶體2205的汲極端彼此電性連接,p型電晶體2200至p型電晶體2205的源極端彼此電性連接,且p型電晶體2200至p型電晶體2205的閘極端彼此電性連接。反相器裝置200以與圖1的反相器裝置100相同的方式操作: 輸入端112處的邏輯高電壓(例如電源電壓130)產生輸出端115處的邏輯低電壓(例如0V),且反之亦然。
在一些實施例中,n型電晶體2100至n型電晶體2103及p型電晶體2200至p型電晶體2205為鰭式場效電晶體(「finFET」)。為便於對反相器裝置200的解釋,使用finFET裝置。本揭露不限於finFET裝置且可包含其他類型的裝置,諸如例如雙閘極裝置、三閘極裝置、ω FET以及環繞式閘極裝置。所屬領域中具通常知識者應理解,基於本文中的揭露內容,這些其他類型的裝置皆落在本揭露的精神及範疇內。
圖3是根據一些實施例的反相器裝置200的三維視圖的示意圖。在圖3中,n型電晶體2100至n型電晶體2101及p型電晶體2200至p型電晶體2202為可見的。n型電晶體2102至n型電晶體2103及p型電晶體2203至p型電晶體2205分別位在n型電晶體2100至n型電晶體2101及p型電晶體2200至p型電晶體2202的後方。
n型電晶體2100及n型電晶體2101的源極端,在圖3中描繪為「菱形」(diamond-shaped)結構,是耦接(或電性連接)至互連結構315(在本文中亦稱作「參考金屬線315」)。這些源極端經由源極觸點310及通孔312耦接至參考金屬線315。在一些實施例中,通孔312及參考金屬線315可使用雙鑲嵌互連製程(dual damascene interconnect process)形成,其中可使用諸如例如銅(copper)、釕(ruthenium)或鈷(cobalt)的金屬。所屬領域中具通常知識者應理解,可用其他互連製程及金屬來形成通孔312及參考金屬線315。儘管未在圖3中示出,但n型電晶體2102及n 型電晶體2103的源極端以與n型電晶體2100及n型電晶體2101類似的方式耦接至第一參考金屬線315。在一些實施例中,參考金屬線315可電性連接至接地(例如0V),諸如接地140。根據一些實施例,互連結構317在參考金屬線315上形成且沿參考金屬線315佈線以使接地自上部互連層(圖3中未示)電性連接至參考金屬線315。
p型電晶體2200至p型電晶體2202的源極端,在圖3中描繪為「菱形」結構,是耦接(或電性連接)至互連結構325(在本文中亦稱作「參考金屬線325」)。這些源極端經由源極觸點320及通孔322耦接至參考金屬線325。在一些實施例中,通孔322及參考金屬線325可使用雙鑲嵌互連製程形成,其中可使用諸如例如銅、釕或鈷的金屬。所屬領域中具通常知識者應理解,可用其他互連製程及金屬來形成通孔322及參考金屬線325。儘管未在圖3中示出,但p型電晶體2203至p型電晶體2205的源極端以與p型電晶體2200至p型電晶體2202類似的方式耦接至參考金屬線325。在一些實施例中,第二參考金屬線325可電性連接至電源電壓,諸如電源電壓130。根據一些實施例,互連結構327在參考金屬線325上形成且沿參考金屬線325佈線以使電源電壓自上部互連層(圖3中未示)電性連接至參考金屬線325。
n型電晶體2100至n型電晶體2103的汲極端,在圖3中描繪為「菱形」結構,是經由汲極觸點(圖3中未示)及通孔330耦接(或電性連接)至互連結構332。在一些實施例中,通孔330可使用單鑲嵌互連製程(single damascene interconnect porcess)形成,其中可使用諸如例如銅、釕或鈷的金屬。所屬領域中具通常知 識者應理解,可用其他互連製程及金屬來形成通孔330。
p型電晶體2200至p型電晶體2205的汲極端,在圖3中描繪為「菱形」結構,是經由汲極觸點(圖3中未示)及通孔340耦接(或電性連接)至互連結構342。在一些實施例中,通孔340可使用單鑲嵌互連製程形成,其中可使用諸如例如銅、釕或鈷的金屬。所屬領域中具通常知識者應理解,可用其他互連製程及金屬來形成通孔340。互連結構342經由通孔334及互連結構350耦接(或電性連接)至互連結構332。互連結構350形成反相器裝置200的輸出端,例如輸出端115。互連結構350可連接至上部互連層(圖3中未示),以將由反相器裝置200產生的輸出信號提供至相同晶片上或晶片外的其他電路。
n型電晶體2100至n型電晶體2103的閘極端及p型電晶體2200至p型電晶體2205的閘極端經由通孔360、通孔362以及局部互連結構365彼此耦接(或電性連接)。在一些實施例中,通孔360、通孔362以及局部互連結構365可使用雙鑲嵌互連製程形成,其中可使用諸如例如銅、釕或鈷的金屬。所屬領域中具通常知識者應理解,可用其他互連製程及金屬來形成通孔360、通孔362以及局部互連結構365。根據一些實施例,互連結構370在局部互連結構365上形成且沿局部互連結構365佈線。局部互連結構365與互連結構370一起形成反相器裝置200的輸入端,例如輸入端112。互連結構370可連接至上部互連層(圖3中未示)以自相同晶片上或晶片外的其他電路接收輸入信號。
在一些實施例中,互連結構370的長度尺寸(length dimension)比局部互連結構365的長度尺寸更短。互連結構370 的長度尺寸可藉由佈局設計規則來確定,所述佈局設計規則對互連結構370的佈線需要一個最小長度,例如用於佈線M0金屬的最小長度。如由所屬領域中具通常知識者所理解,佈局設計規則可因在不同半導體製造技術節點上而改變。
佈線局部互連結構365以耦接反相器裝置200的閘極端以及佈線具有經縮短之長度尺寸或最小長度尺寸的互連結構370的一個益處為透過寄生電容之減少而提高的裝置效能。舉例而言,互連結構370佈線在與互連結構332及互連結構342相同的互連層(例如在M0金屬層)且與這些互連結構形成寄生電容:(i)在互連結構370與互連結構332之間的寄生電容;以及(ii)在互連結構370與互連結構342之間的寄生電容。這些寄生電容透過例如由於寄生電容所誘導的兩個端之電耦接(electrical coupling)而在反相器裝置的輸入端及輸出端處導致信號完整性問題,從而影響裝置效能。上述寄生電容的減少會使電耦接減少,因此提高裝置效能。
如由所屬領域中具通常知識者所理解,寄生電容與形成寄生電容之板件的面積成正比,且與板件之間的距離成反比。此關係可表述為:
Figure 107134218-A0305-02-0011-1
其中C為電容;ε為電容器的板件之間的材料的介電常數;A為板件的面積;以及d為板件之間的距離。
隨著板件的面積減小,寄生電容相應地減少。另外,隨著板件之間的距離增加,寄生電容相應地減少。
就形成寄生電容之板件的面積而言,由於互連結構370縮短或處於最小長度,因此在互連結構370與互連結構332及互連結構342之間形成寄生電容之板件的面積減小。另外,就板件之間的距離而言,由於在互連結構370與互連結構332之間以及在互連結構370與互連結構342之間不存在互連結構,因此互連結構332與互連結構342之間的互連結構370的置放,例如置放於中間,可被最大化。此最大化距離亦減少寄生電容。
雖然以上實施例描述是使用局部互連結構365使反相器裝置200的閘極端彼此耦接的情況,但是基於本文中的描述,所屬領域中具通常知識者應理解,局部互連結構,諸如類似於局部互連結構365的結構,亦可用以使一或多個汲極端與/或一或多個源極端彼此耦接。類似於以上描述之局部互連結構365,用於汲極端與/或源極端的局部互連結構的使用亦可達成減少寄生電容的益處。將局部互連結構應用於汲極端及/或源極端(以及應用於閘極端)皆落在本揭露的精神及範疇內。
圖4為自圖3中的截面線A-A'所截取的反相器裝置200的橫截面視圖。在一些實施例中,互連佈線(interconnect routing)可分為四個互連層級:互連層級400、互連層級410、互連層級420以及互連層級430。
互連層級400可包含n型電晶體2100至n型電晶體2103及p型電晶體2200至p型電晶體2205的汲極觸點。根據一些實施例,互連層級400亦可包含通孔330的一部分、通孔340的一部分以及通孔362。
互連層級410可包含通孔330的剩餘部分、通孔340的 剩餘部分、參考金屬線315、參考金屬線325以及局部互連結構365。在一些實施例中,參考金屬線315、參考金屬線325以及局部互連結構365在相同的互連層級410中佈線。在一些實施例中,相同類型的金屬(例如銅、釕或鈷)可用以形成參考金屬線315、參考金屬線325以及局部互連結構365。
互連層級420可包含互連結構317、互連結構327、互連結構332、互連結構342以及互連結構370。根據一些實施例,這些互連結構在M0互連層級中佈線。上述M0互連層級可用以表示使鄰近裝置彼此耦接(或電性連接)的局部互連層級,所述鄰近裝置諸如例如n型電晶體2100至n型電晶體2103及p型電晶體2200至p型電晶體2205
互連層級430可包含通孔334、通孔344以及互連結構350。在一些實施例中,通孔334、通孔344以及互連結構350在M1互連層級中佈線。上述M1互連層級可用以表示使鄰近裝置彼此耦接(或電性連接)的另一個局部互連層級,所述鄰近裝置諸如例如n型電晶體2100至n型電晶體2103及p型電晶體2200至p型電晶體2205
圖5是根據一些實施例的反相器裝置500的電路表示的示意圖。反相器裝置500具有包含n型電晶體5100至n型電晶體5103及p型電晶體5200至p型電晶體5203的多閘極電晶體結構。n型電晶體5100至n型電晶體5103彼此以並聯方式電性連接:電n型電晶體5100至n型電晶體5103的汲極端彼此電性連接,n型電晶體5100至n型電晶體5103的源極端彼此電性連接,且n型電晶體5100至n型電晶體5103的閘極端彼此電性連接。類似地,p 型電晶體5200至p型電晶體5203彼此以並聯方式電性連接:p型電晶體5200至p型電晶體5203的汲極端彼此電性連接,p型電晶體5200至p型電晶體5203的源極端彼此電性連接,且p型電晶體5200至p型電晶體5203的閘極端彼此電性連接。反相器裝置500以與圖1的反相器裝置100相同的方式操作:輸入端112處的邏輯高電壓(例如電源電壓130)產生輸出端115處的邏輯低電壓(例如0V),反之亦然。
在一些實施例中,n型電晶體5100至n型電晶體5103及p型電晶體5200至p型電晶體5203為鰭式場效電晶體(「FinFET」)。本揭露不限於finFET裝置且可包含其他類型的裝置,諸如例如雙閘極裝置、三閘極裝置、ω FET以及環繞式閘極裝置。所屬領域中具通常知識者應理解,基於本文中的揭露內容,其他類型的裝置皆落在本揭露的精神及範疇內。
圖6是根據一些實施例的反相器裝置500的頂層佈局圖的示意圖。在一些實施例中,輸入端112可藉由互連結構670及局部互連結構665形成。局部互連結構665可經由閘極觸點682、閘極觸點684、閘極觸點686以及閘極觸點688與n型電晶體5100至n型電晶體5103的閘極端及p型電晶體5200至p型電晶體5203的閘極端形成電性連接。互連結構670及局部互連結構665彼此實體接觸,因此互連結構670可耦接(或電性連接)至互連層級以接收輸入端112處的信號。
互連結構670可佈線在與輸出端115相同的互連層級,所述輸出端115耦接(或電性連接)至p型電晶體5200至p型電晶體5203的汲極端及n型電晶體5100至n型電晶體5103的源極 端。互連結構670可在諸如圖4中的互連層級420的M0互連層級中佈線。在一些實施例中,局部互連結構665可在互連結構670下方的互連層級(諸如圖4中的互連層級410)中佈線。
在一些實施例中,互連結構670的長度尺寸比局部互連結構665的長度尺寸更短。舉例而言,如圖6中所示,互連結構670的長度橫跨2個閘極觸點(亦即閘極觸點682及閘極觸點684),而局部互連結構665的長度橫跨4個閘極觸點(亦即閘極觸點682、閘極觸點684、閘極觸點686以及閘極觸點688)。互連結構670的長度尺寸可藉由佈局設計規則來確定,所述佈局設計規則對互連結構670的佈線需要一個最小長度,例如用於佈線M0金屬的最小長度。如由所屬領域中具通常知識者所理解,佈局設計規則可因在不同半導體製造技術節點上而改變。佈線局部互連結構665以耦接反相器裝置500的閘極端以及佈線具有經縮短之長度尺寸或最小長度尺寸的互連結構670的一個益處為透過寄生電容的減少而提高之裝置效能。
