Description

半導體裝置及其製造方法
本發明之實施方式係關於一種半導體裝置及其製造方法。
已知將形成半導體元件之2片晶圓貼合之混合接合(hybrid bonding)技術。於混合接合技術中,將分別形成於各晶圓表面之連接墊彼此接合。為了避免該連接墊之接合不良,存在配置虛設墊(dummy pad)之情形。於該情形時,於配線與虛設墊之間可產生寄生電容。
本發明所欲解決之問題在於提供一種能夠改善由虛設墊所導致之缺陷之半導體裝置及其製造方法。
一實施方式之半導體裝置具備第1晶片及第2晶片。第1晶片具有第1配線、與第1配線電性連接之第1連接墊、及第1虛設墊。第2晶片具有第2配線、與第2配線電性連接並且與第1連接墊接合之第2連接墊、及與第1虛設墊接合之第2虛設墊。第1虛設墊之厚度小於第1連接墊之厚度且第2虛設墊之厚度亦小於第2連接墊之厚度,或者,第1虛設墊之厚度小於第1連接墊之厚度或第2虛設墊之厚度小於第2連接墊之厚度。
以下,參照附圖對本發明之實施方式進行說明。於以下之實施方式中,對具有三維構造之記憶胞陣列之半導體裝置進行說明。該半導體裝置係能夠電性地自由進行資料之抹除及寫入,且即便切斷電源亦能夠保存記憶內容之NAND(Not AND,反及)型非揮發性半導體記憶裝置。然而,本發明不僅可應用於上述半導體記憶裝置,亦可應用於例如CMOS(Complementary Metal Oxide Semiconductor,互補金屬氧化物半導體)影像感測器。
(第1實施方式) 圖1係概略性地表示第1實施方式之半導體裝置之主要部分之構造之剖視圖。於圖1所示之半導體裝置1中,陣列晶片10及電路晶片20於Z方向貼合。陣列晶片10係第1晶片之例子,電路晶片20係第2晶片之例子。又,Z方向係鉛直方向,X方向及Y方向係與Z方向正交之水平方向。
首先,對陣列晶片10進行說明。陣列晶片10具有第1配線11、第1接觸通孔12、第1連接墊13、及第1虛設墊14。再者,陣列晶片10除該等構件以外,亦具有三維構造之記憶胞、字元線、及位元線等。
第1配線11具有金屬膜11a及阻擋金屬11b。金屬膜11a例如包含銅(Cu),形成於擋止膜16上。擋止膜16例如為包含氮化矽(SiN)之膜。阻擋金屬11b例如包含氮化鉭(TaN),覆蓋金屬膜11a之表面。又,於本實施方式中,複數個第1配線11形成於擋止膜16上,各第1配線11隔著層間絕緣膜15而相互絕緣。
第1接觸通孔12例如包含鎢。第1接觸通孔12之一端貫通擋止膜16而與第1配線11之金屬膜11a接觸。第1接觸通孔12之另一端與第1連接墊13之阻擋金屬13b接觸。
第1連接墊13經由第1接觸通孔12與第1配線11電性連接,具有金屬膜13a及阻擋金屬13b。金屬膜13a例如包含銅。阻擋金屬13b例如包含氮化鉭,覆蓋金屬膜13a。又,於本實施方式中,複數個第1連接墊13分別配置於複數個第1配線11之下方,各第1連接墊13隔著層間絕緣膜15而相互絕緣。
第1虛設墊14具有金屬膜14a及阻擋金屬14b。金屬膜14a與金屬膜13a同樣地包含銅。阻擋金屬14b與阻擋金屬13b同樣地包含氮化鉭,覆蓋金屬膜14a。
於本實施方式中,第1虛設墊14與第1配線11之間利用層間絕緣膜15及擋止膜16而絕緣。即,第1虛設墊14不與第1配線11電性連接。又,第1虛設墊14自與電路晶片20之接合面算起之厚度h11小於第1連接墊13自與電路晶片20之接合面算起之厚度h12。例如,厚度h11為300 nm,厚度h12為500 nm。
圖2係表示第1連接墊13及第1虛設墊14之佈局之一例之俯視圖。如圖2所示,第1連接墊13及第1虛設墊14無需交替配置。第1虛設墊14於陣列晶片10與電路晶片20之接合區域中,可任意配置於未形成有第1連接墊13之間隙區域。
其次,參照圖1對電路晶片20進行說明。電路晶片20具有第2配線21、第2接觸通孔22、第2連接墊23、及第2虛設墊24。再者,電路晶片20除該等零件以外,亦具有設置於陣列晶片10之記憶胞之驅動元件(例如,電晶體)等。
第2配線21與上述驅動元件電性連接,具有金屬膜21a及阻擋金屬21b。金屬膜21a例如包含銅(Cu),形成於擋止膜26下。擋止膜26例如為包含氮化矽(SiN)之膜。阻擋金屬11b例如包含氮化鉭(TaN),覆蓋金屬膜21a之表面。又,於本實施方式中,複數個第2配線21形成於擋止膜26上,各第2配線21隔著層間絕緣膜25而相互絕緣。
第2接觸通孔22例如包含鎢。第2接觸通孔22之一端貫通擋止膜26而與第2配線21之金屬膜21a接觸。第2接觸通孔22之另一端與第2連接墊23之阻擋金屬23b接觸。
第2連接墊23經由第2接觸通孔22與第2配線21電性連接,具有金屬膜23a及阻擋金屬23b。金屬膜23a與第1連接墊13之金屬膜13a同樣地包含銅,與金屬膜13a接合。阻擋金屬23b與第1連接墊13之阻擋金屬13b同樣地包含氮化鉭,覆蓋金屬膜23a,並且與阻擋金屬13b接合。
於本實施方式中,複數個第2連接墊23分別配置於複數個第2配線21之下方,各第2連接墊23隔著層間絕緣膜25而相互絕緣。又,第1連接墊13與第2連接墊23之接合面係1邊為1 μm之正方形。
第2虛設墊24具有金屬膜24a及阻擋金屬24b。金屬膜24a與第1虛設墊14之金屬膜14a同樣地包含銅,與金屬膜14a接合。阻擋金屬24b與阻擋金屬14b同樣地包含氮化鉭,覆蓋金屬膜24a,並且與阻擋金屬14b接合。
於本實施方式中,第2虛設墊24與第2配線21之間利用層間絕緣膜25及擋止膜26而絕緣。即,第2虛設墊24不與第2配線21電性連接。又,第2虛設墊24自與陣列晶片10之接合面算起之厚度h21小於第2連接墊23自與陣列晶片10之接合面算起之厚度h22。例如,厚度h21與厚度h11相等,為300 nm,厚度h22與厚度h12相等,為500 nm。進而,第1虛設墊14與第2虛設墊24之接合面與連接墊彼此之接合面相同,亦為1邊為1 μm之正方形。
圖3係概略性地表示比較例之半導體裝置之主要部分之構造之剖視圖。對於與上述第1實施方式之半導體裝置1相同之構成要素,標上相同符號,並省略詳細說明。
於圖3所示之半導體裝置100之陣列晶片10中,第1虛設墊14之厚度h11與第1連接墊13之厚度h12相等,因此,第1虛設墊14與第1配線11之距離D11變短。由此,第1虛設墊14與第1配線11之間之寄生電容變大。同樣,於電路晶片20中,第2虛設墊24之厚度h21與第2連接墊23之厚度h22相等,因此,第2虛設墊24與第2配線21之距離D21變短。其結果,第2虛設墊24與第2配線21之間之寄生電容亦變大。
一方面,於本實施方式之陣列晶片10中,如圖1所示,第1虛設墊14之厚度h11小於第1連接墊13之厚度h12,因此,第1虛設墊14與第1配線11之距離D11較比較例變長。由此,第1虛設墊14與第1配線11之間之寄生電容減小。同樣,於電路晶片20中,第2虛設墊24之厚度h21小於第2連接墊23之厚度h22,因此,第2虛設墊24與第2配線21之距離D21較比較例變長。其結果,第2虛設墊24與第2配線21之間之寄生電容亦減小。
因此,根據本實施方式,由於虛設墊與配線之間之寄生電容減小,故而能夠避免由該寄生電容所導致之缺陷。
(第2實施方式) 圖4係概略性地表示第2實施方式之半導體裝置之主要部分之構造之剖視圖。對於與上述之第1實施方式之半導體裝置1相同之構成要素,標上相同符號,並省略詳細說明。
本實施方式之半導體裝置2具有無通孔(via-less)構造。即,於陣列晶片10中,第1連接墊13不經由第1接觸通孔12而直接與第1配線11連接,於電路晶片20中,第2連接墊23不經由第1接觸通孔12而直接與第2配線21連接。
又,於本實施方式中,與第1實施方式相同,第1虛設墊14之厚度小於第1連接墊13之厚度,第2虛設墊24之厚度亦小於第2連接墊23之厚度。於本實施方式中,若第1虛設墊14之厚度與第1連接墊13之厚度相等,且第2虛設墊24之厚度與第2連接墊23之厚度相等,則本來應絕緣之第1配線11與第2配線21經由第1虛設墊14及第2虛設墊24而連接,藉此產生短路。
對此,於本實施方式中,藉由使各虛設墊之厚度小於各連接墊之厚度,而防止各虛設墊與各配線之接觸。藉此,能夠防止由第1虛設墊14及第2虛設墊24所導致之短路。
(第3實施方式) 圖5係概略性地表示第3實施方式之半導體裝置之主要部分之構造之剖視圖。對於與上述之第1實施方式之半導體裝置1相同之構成要素,標上相同符號,並省略詳細說明。
於圖5所示之半導體裝置3之陣列晶片10中,第1虛設墊14之厚度h11與第1連接墊13之厚度h12相等。又,第1虛設墊14經由第1接觸通孔12與第1配線11連接。於電路晶片20中,第2虛設墊24之厚度h21與第2連接墊23之厚度h22相等,另一方面,第2虛設墊24未與第2配線21連接。
此處,對於第1虛設墊14與第1配線11之間之寄生電容,與圖3所示之比較例之半導體裝置100進行比較。半導體裝置100中,由於第1虛設墊14未與第1配線11連接,故第1虛設墊14之電位為浮動狀態。
另一方面,如圖5所示,本實施方式中,由於第1虛設墊14與第1配線11電性連接,故而第1虛設墊14與第1配線11之電位差大致消失,因此寄生電容減小。由此,能夠避免由該寄生電容引起之缺陷。
又,本實施方式中,由於第2虛設墊24未與第2配線21電性連接,故維持原本應絕緣之第1配線11與第2配線21之狀態。因此,亦能夠避免經由第1虛設墊14及第2虛設墊24之配線短路。再者,本實施方式中亦可為,第1虛設墊14未與第1配線11電性連接,第2虛設墊24與第2配線21電性連接。
(變化例1) 圖6係概略性地表示第3實施方式之變化例之半導體裝置之主要部分之構造之剖視圖。對於與上述之第3實施方式之半導體裝置3相同之構成要素,標上相同符號,並省略詳細說明。
於圖6所示之半導體裝置3a之陣列晶片10中,第1連接墊13及第1虛設墊14不經由第1接觸通孔12而與第1配線11直接連接。另一方面,於電路晶片20中,第2連接墊23經由第2接觸通孔22與第2配線21連接,但第1虛設墊14未與第2配線21連接。
如上述構成之本變化例中,亦與第3實施方式相同,由於第1虛設墊14與第1配線11之電位差大致消失,故而兩者之間之寄生電容減小。由此,能夠避免由該寄生電容引起之缺陷。又,由於第2虛設墊24未與第2配線21電性連接,因此,亦能夠避免第1配線11與第2配線21短路。再者,本變化例中亦可為,第1虛設墊14不與第1配線11電性連接,第2虛設墊24與第2配線21直接連接。
(變化例2) 圖7係概略性地表示第3實施方式之另一變化例之半導體裝置之主要部分之構造之剖視圖。對於與上述之第3實施方式之半導體裝置3相同之構成要素,標上相同符號,並省略詳細說明。
於圖7所示之半導體裝置3b中,相互接合之第1虛設墊14及第2虛設墊24經由第1接觸通孔12或第2接觸通孔22而僅與第2配線21及第2配線21中之任一者連接。於第2虛設墊24經由第2接觸通孔22與第2配線21連接之情形時,兩者之電位差大致消失,因此,能夠減小寄生電容。於該情形時,第1虛設墊14不與第2配線21連接,因此,亦能夠避免第1配線11與第2配線21之短路。
再者,於本變化例中,關於將相互接合之第1虛設墊14及第2虛設墊24與第1配線11及第2配線21之哪一個連接,模擬寄生電容之值並選擇電容值變小之配線即可。
(第4實施方式) 圖8係概略性地表示第4實施方式之半導體裝置之主要部分之構造之剖視圖。對於與上述之第1實施方式之半導體裝置1相同之構成要素,標上相同符號,並省略詳細說明。
於圖8所示之半導體裝置4之陣列晶片10中,第1虛設墊14之厚度與第1連接墊13之厚度相等。又,第1虛設墊14及第1連接墊13不經由第1接觸通孔12而與第1配線11接觸。
另一方面,於電路晶片20中,第1虛設墊14之厚度小於第2連接墊23之厚度。例如,第2連接墊23之厚度為500 nm,第2虛設墊24之厚度例如為300 nm。又,第2連接墊23與第2配線21接觸,與此相對,第2虛設墊24不與第2配線21連接。
根據本實施方式,由於第1虛設墊14與第2配線21連接,故而能夠減小兩者之間之寄生電容。又,由於第2虛設墊24之厚度小於第2連接墊23之厚度,故而亦能夠減小第2虛設墊24與第2配線21之間之寄生電容。進而,由於第2虛設墊24不與第2配線21連接,故而亦能夠防止由第1虛設墊14及第2虛設墊24所導致之第1配線11與第2配線21之短路。再者,於本實施方式中,第1虛設墊14之厚度可小於第1連接墊13之厚度,第2虛設墊24之厚度可與第2連接墊23之厚度相等。
(變化例3) 圖9係概略性地表示第4實施方式之變化例之半導體裝置之主要部分之構造之剖視圖。對於與上述之第4實施方式之半導體裝置4相同之構成要素,標上相同符號,並省略詳細說明。
於圖9所示之半導體裝置4a中,相互接合之第1虛設墊14及第2虛設墊24僅與第2配線21及第2配線21中之任一者直接連接。於第2虛設墊24與第2配線21接觸之情形時,兩者之電位差大致消失,因此,能夠減小寄生電容。
又,於本實施方式中,由於第1虛設墊14之厚度小於第1連接墊13之厚度,故而亦能夠減小第1虛設墊14與第1配線11之間之寄生電容。進而,由於第1虛設墊14不與第1配線11連接,故而亦能夠防止經由第1虛設墊14及第2虛設墊24之第1配線11與第2配線21之短路。
再者,於本變化例中,關於將相互接合之第1虛設墊14及第2虛設墊24與第1配線11及第2配線21之哪一個直接連接,模擬寄生電容之值並選擇電容值變小之配線即可。
(第5實施方式) 於第5實施方式中,參照圖10A~圖10J,對上述之第1實施方式之半導體裝置1之製造方法之一例進行說明。
首先,如圖10A所示,於形成於陣列晶圓101(基板)之具有三維構造之複數個記憶胞陣列上形成第1配線11及第1接觸通孔12,繼而,於該等之上積層擋止膜16及層間絕緣膜15。再者,由於第1配線11及第1接觸通孔12可藉由通常所用之方法形成,故而省略說明。
形成於第1接觸通孔12上之擋止膜16例如為具有50 nm之厚度之氮化矽膜。又,形成於擋止膜16上之層間絕緣膜15例如為具有550 nm之厚度之氧化矽膜。
其次,如圖10B所示,於層間絕緣膜15上形成抗蝕劑30。
其次,如圖10C所示,使用微影法於抗蝕劑30形成具有凹部31之圖案。凹部31位於層間絕緣膜15中之第1虛設墊14之形成區域上。
其次,如圖10D所示,藉由乾式蝕刻,將抗蝕劑30作為遮罩而去除層間絕緣膜15,直至擋止膜16露出為止。藉此,用於形成第1虛設墊14之凹部15a形成於層間絕緣膜15。
其次,如圖10E所示,於層間絕緣膜15上再次形成抗蝕劑30。此時,抗蝕劑30嵌入凹部15a內。
其次,如圖10F所示,使用微影法於抗蝕劑30形成具有凹部32之圖案。凹部32位於層間絕緣膜15中之第1連接墊13之形成區域上。
其次,如圖10G所示,藉由乾式蝕刻,將抗蝕劑30作為遮罩去除層間絕緣膜15及擋止膜16,直至第1接觸通孔12露出為止。藉此,用於形成第1連接墊13之凹部15b形成於層間絕緣膜15。此時,藉由去除嵌入凹部15a之抗蝕劑30,凹部15a再次露出。
其次,如圖10H所示,於凹部15a及凹部15b之表面形成阻擋金屬40,繼而,嵌入金屬膜41。例如,阻擋金屬40為氮化鉭膜,金屬膜41為銅膜。
其次,如圖10I所示,藉由CMP(Chemical Mechanical Polishing,化學機械拋光)步驟,去除多餘之金屬膜41及阻擋金屬40,並且去除例如100 nm之厚度之層間絕緣膜15。其結果,第1連接墊13及第1虛設墊14形成於層間絕緣膜15內。於本實施方式中,由於存在第1虛設墊14,故而能夠防止CMP步驟中之階差產生。
其次,如圖10J所示,使陣列晶圓101翻轉180度而與電路晶圓201貼合。其後,藉由熱處理,陣列晶圓101之第1連接墊13及第1虛設墊14與電路晶圓201之第2連接墊23及第2虛設墊24分別接合。第2連接墊23及第2虛設墊24於與陣列晶圓101貼合之前,藉由與上述第1連接墊13及第1虛設墊14相同之方法而形成。
其後,藉由對相互貼合之陣列晶圓101及電路晶圓201進行切割,包含陣列晶片10及電路晶片20之半導體裝置1完成。
根據本實施方式,藉由利用與第1連接墊13不同之步驟形成第1虛設墊14,能夠使第1虛設墊14之厚度形成為小於第1連接墊13之厚度。又,第2虛設墊24由於與第1虛設墊14同樣地形成,故而亦能夠形成為小於第2連接墊23之厚度。進而,根據本實施方式,藉由於陣列晶圓101及電路晶圓201之兩者分別形成虛設墊及連接墊,而使虛設墊之厚度小於連接墊之厚度,藉由僅於陣列晶圓101或電路晶圓201之一者分別形成虛設墊及連接墊,可僅使一者之虛設墊之厚度小於連接墊之厚度。
再者,於本實施方式中,為了形成第1虛設墊14及第2虛設墊24,使用擋止膜16、26,亦可不使用擋止膜16、26。圖1記載之半導體裝置1不使用擋止膜16、26而形成第1虛設墊14及第2虛設墊24。於不使用擋止膜16、26之情形時,能夠藉由調整層間絕緣膜15之蝕刻時間,而控制各虛設墊之厚度。
(第6實施方式) 於第6實施方式中,參照圖11A~圖11J,對具有無通孔構造之半導體裝置之製造方法之一例進行說明。
首先,如圖11A所示,於陣列晶圓101之第1配線11上積層擋止膜16及層間絕緣膜15。擋止膜16例如為具有50 nm之厚度之氮化矽膜。又,層間絕緣膜15例如為具有550 nm之厚度之氧化矽膜。
其次,如圖11B所示,於層間絕緣膜15上形成抗蝕劑30。
其次,如圖11C所示,使用微影法於抗蝕劑30形成具有凹部31之圖案。凹部31位於層間絕緣膜15中之第1虛設墊14之形成區域上。
其次,如圖11D所示,藉由乾式蝕刻,將抗蝕劑30作為遮罩去除層間絕緣膜15,直至擋止膜16露出為止。藉此,用於形成第1虛設墊14之凹部15a形成於層間絕緣膜15上。
其次,如圖11E所示,於層間絕緣膜15上再次形成抗蝕劑30。此時,抗蝕劑30嵌入凹部15a內。
其次,如圖11F所示,使用微影法於抗蝕劑30形成具有凹部32之圖案。凹部32位於層間絕緣膜15中之第1連接墊13之形成區域上。
其次,如圖11G所示,藉由乾式蝕刻,將抗蝕劑30作為遮罩去除層間絕緣膜15及擋止膜16,直至第1配線11露出為止。藉此,用於形成第1連接墊13之凹部15b形成於層間絕緣膜15。此時,藉由去除嵌入凹部15a之抗蝕劑30,凹部15a再次露出。
其次,如圖11H所示,於凹部15a及凹部15b之表面形成阻擋金屬40,繼而,嵌入金屬膜41。例如,阻擋金屬40為氮化鉭膜,金屬膜41為銅膜。
其次,如圖11I所示,藉由CMP步驟,去除多餘之金屬膜41及阻擋金屬40,並且去除例如100 nm之厚度之層間絕緣膜15。其結果,第1連接墊13及第1虛設墊14形成於層間絕緣膜15內。於本實施方式中,由於存在第1虛設墊14,故而能夠防止CMP步驟中之階差產生。
其次,如圖11J所示,使陣列晶圓101翻轉180度而與電路晶圓201貼合。其後,藉由熱處理,陣列晶圓101之第1連接墊13及第1虛設墊14與電路晶圓201之第2連接墊23及第2虛設墊24分別接合。第2連接墊23及第2虛設墊24於與陣列晶圓101貼合之前,藉由與上述第1連接墊13及第1虛設墊14相同之方法而形成。
其後,藉由對相互貼合之陣列晶圓101及電路晶圓201進行切割,具有無通孔構造之半導體裝置完成。
根據本實施方式,與第5實施方式相同,藉由利用與第1連接墊13不同之步驟形成第1虛設墊14,能夠使第1虛設墊14之厚度形成為小於第1連接墊13之厚度。又,第2虛設墊24由於與第1虛設墊14同樣地形成,故而亦能夠形成為小於第2連接墊23之厚度。進而,根據本實施方式,藉由於陣列晶圓101及電路晶圓201之兩者分別形成虛設墊及連接墊,而使虛設墊之厚度小於連接墊之厚度,藉由僅於陣列晶圓101或電路晶圓201之一者分別形成虛設墊及連接墊,可僅使一者之虛設墊之厚度小於連接墊之厚度。
再者,於本實施方式中,與第5實施方式相同,為了形成第1虛設墊14及第2虛設墊24,使用擋止膜16、26,亦可不使用擋止膜16、26。於該情形時,能夠藉由調整層間絕緣膜15之蝕刻時間,而控制第1虛設墊14及第2虛設墊24之厚度。
(第7實施方式) 於第7實施方式中,參照圖12A~圖12G,對具有無通孔構造之半導體裝置之製造方法之另一例進行說明。
首先,如圖12A所示,於陣列晶圓101之第1配線11上積層擋止膜16及層間絕緣膜15。擋止膜16例如為具有50 nm之厚度之氮化矽膜。又,層間絕緣膜15例如為具有550 nm之厚度之氧化矽膜。
其次,如圖12B所示,於層間絕緣膜15上形成抗蝕劑30。
其次,如圖12C所示,使用灰度微影法於抗蝕劑30同時形成具有凹部33及凹部34之圖案。凹部33位於層間絕緣膜15中之第1虛設墊14之形成區域上。另一方面,凹部34位於層間絕緣膜15中之第1連接墊13之形成區域上。更詳細而言,藉由使用與凹部33對應之透過率小於與凹部34對應之透過率之光罩的微影法,將抗蝕劑30形成為於凹部33中比於凹部34中更厚。
其次,如圖12D所示,藉由乾式蝕刻,將抗蝕劑30作為遮罩而去除層間絕緣膜15。藉此,將凹部15a及凹部15b同時形成於層間絕緣膜15。凹部15a未到達至擋止膜16,而於層間絕緣膜15內終止。另一方面,凹部15b貫通擋止膜16而到達至金屬膜11a。
其次,如圖12E所示,於凹部15a及凹部15b之表面形成阻擋金屬40,繼而,嵌入金屬膜41。例如,阻擋金屬40為氮化鉭膜,金屬膜41為銅膜。
其次,如圖12F所示,藉由CMP步驟,去除多餘之金屬膜41及阻擋金屬40,且將層間絕緣膜15去除例如100 nm之厚度。其結果,於層間絕緣膜15內形成第1連接墊13及第1虛設墊14。於本實施方式中,由於存在第1虛設墊14,故而能夠防止於CMP步驟中產生階差。
其次,如圖12G所示,使陣列晶圓101翻轉180度而貼合於電路晶圓201。其後,藉由熱處理,將陣列晶圓101之第1連接墊13及第1虛設墊14與電路晶圓201之第2連接墊23及第2虛設墊24分別接合。第2連接墊23及第2虛設墊24係於與陣列晶圓101貼合之前,藉由與上述第1連接墊13及第1虛設墊14相同之方法而形成。
其後,藉由對相互貼合之陣列晶圓101及電路晶圓201進行切割,完成具有無通孔構造之另一半導體裝置。該另一半導體裝置相當於圖4所示之第2實施方式之半導體裝置2。
根據本實施方式,藉由使用灰度微影法對抗蝕劑30進行圖案化,而同時形成第1虛設墊14用之凹部15a及第1連接墊13用之凹部15b。藉此,與上述第6實施方式相比,能夠縮短製造時間。再者,抗蝕劑30之圖案化方法並不限定於灰度微影法。例如,亦可使用將具有凹凸圖案之模板壓抵於抗蝕劑之奈米壓印技術。於該情形時,藉由將具有帶有深度不同之2種凹部的圖案之模板壓抵於抗蝕劑30,亦能夠同時形成凹部15a及凹部15b。進而,根據本實施方式,藉由於陣列晶圓101及電路晶圓201之兩者使用灰度微影法,而使虛設墊之厚度小於連接墊之厚度,藉由僅於陣列晶圓101或電路晶圓201之一者使用灰度微影法,可僅使一者之虛設墊之厚度小於連接墊之厚度。
又,於本實施方式中,對第1配線11及第1連接墊13不經由第1接觸通孔12而直接連接之無通孔構造之半導體裝置之製造方法進行說明。然而,亦可將本實施方式應用於具有第1配線11及第1連接墊13經由第1接觸通孔12連接之構造之半導體裝置之製造方法。
(第8實施方式) 於第8實施方式中,參照圖13A~圖13G,對具有無通孔構造之半導體裝置之製造方法之再一例進行說明。
首先,如圖13A所示,於陣列晶圓101之第1配線11上積層擋止膜16及層間絕緣膜15。擋止膜16例如為具有30 nm之厚度之氮化矽膜。又,層間絕緣膜15例如為具有600 nm之厚度之氧化矽膜。
其次,如圖13B所示,於層間絕緣膜15上形成抗蝕劑30。
其次,如圖13C所示,使用微影法於抗蝕劑30同時形成具有凹部35及凹部36之圖案。凹部35位於層間絕緣膜15中之第1虛設墊14之形成區域上。另一方面,凹部36位於層間絕緣膜15中之第1連接墊13之形成區域上。又,凹部35之X方向之開口寬度W1小於凹部36之X方向之開口寬度W2。例如,開口寬度W1為0.3 μm,開口寬度W2為1 μm。
其次,如圖13D所示,藉由乾式蝕刻,將抗蝕劑30作為遮罩去除層間絕緣膜15。藉此,凹部15a及凹部15b同時形成於層間絕緣膜15。於本實施方式中,如上所述形成於抗蝕劑30之凹部35之開口寬度W1小於凹部36之開口寬度W2。由此,藉由負載效應(loading effect),凹部15a於層間絕緣膜15內終止,另一方面,凹部15b貫通層間絕緣膜15及擋止膜16而到達金屬膜11a為止。
其次,如圖13E所示,於凹部15a及凹部15b之表面形成阻擋金屬40,繼而,嵌入金屬膜41。例如,阻擋金屬40為氮化鉭膜,金屬膜41為銅膜。
其次,如圖13F所示,藉由CMP步驟,去除多餘之金屬膜41及阻擋金屬40,並且去除例如100 nm之厚度之層間絕緣膜15。其結果,第1連接墊13及第1虛設墊14形成於層間絕緣膜15內。於本實施方式中,由於存在第1虛設墊14,故而能夠防止CMP步驟中之階差產生。
其次,如圖13G所示,使陣列晶圓101翻轉180度而與電路晶圓201貼合。其後,藉由熱處理,陣列晶圓101之第1連接墊13及第1虛設墊14與電路晶圓201之第2連接墊23及第2虛設墊24分別接合。第2連接墊23及第2虛設墊24於與陣列晶圓101貼合之前,藉由與上述第1連接墊13及第1虛設墊14相同之方法而形成。
其後,藉由對相互貼合之陣列晶圓101及電路晶圓201進行切割,具有無通孔構造之又一半導體裝置完成。於該半導體裝置中,第1虛設墊14及第2虛設墊24之接合面積小於第1連接墊13與第2連接墊23之接合面積。
根據本實施方式,於抗蝕劑30同時形成寬度不同之凹部35、36。又,於將抗蝕劑30作為遮罩之乾式蝕刻步驟中,藉由負載效應,第1虛設墊14用之凹部15a之深度小於第1連接墊13用之凹部15b之深度。其結果,藉由1個微影步驟及1個乾式蝕刻步驟能夠形成厚度小於第1連接墊13之第1虛設墊14。進而,根據本實施方式,於陣列晶圓101及電路晶圓201之兩者利用負載效應使虛設墊之厚度小於連接墊之厚度,藉由於任一晶圓使用負載效應較大之乾式蝕刻條件,於另一晶圓使用負載效應較小之乾式蝕刻條件,可僅使一者之虛設墊之厚度小於連接墊之厚度。
再者,於本實施方式中,對第1配線11及第1連接墊13不經由第1接觸通孔12而直接連接之無通孔構造之半導體裝置之製造方法進行說明。然而,亦可將本實施方式應用於具有第1配線11及第1連接墊13經由第1接觸通孔12連接之構造之半導體裝置之製造方法。
以上對本發明之一些實施方式進行了說明,然而,該等實施方式係作為例子而提出,並未意圖限定發明之範圍。該等實施方式可藉由其他各種方式而實施,可於不脫離發明之主旨之範圍內,進行各種省略、替換、變更。該等實施方式或其變化包含於發明之範圍或主旨內,同樣包含於申請專利範圍記載之發明及其均等之範圍內。
