參考圖1,示出了流程圖,所述流程圖示出根據本發明的實施例的半導體裝置(100)的製造方法。
如圖1中所示,半導體裝置(100)的製造方法包含:準備晶圓(S1)、背面研磨(S2)、切割(dicing)(S3)、安裝半導體晶片(S4)、移除晶圓基板(S5)、囊封(S6)、形成再分佈層(S7)、形成導電凸塊(S8)以及單一化(S9)。
參考圖2A到2J,示出了橫截面圖,所述橫截面圖示出圖1中所示的半導體裝置(100)的製造方法的各種步驟。
在下文中,將參考圖1和圖2A到2J描述半導體裝置的製造方法。
如圖2A中所示,在準備晶圓過程中(S1),在晶圓基板10上準備晶圓,所述晶圓包含在晶圓基板上相繼形成的氧化物層110、半導體 層120以及後段製程(back end of line,BEOL)層130。
氧化物層110可以在晶圓基板10的第一表面10a上形成至預定厚度。晶圓基板10可以是矽基板,但本發明的各態樣並不限於此。氧化物層110可以是氧化矽層,具有在由矽製成的晶圓基板10與後續待描述的半導體層120之間的良好介面特性。使用選自由以下組成的群組的一種在晶圓基板10的整個頂部區域上形成氧化物層130:熱氧化、化學氣相沉積(CVD)、物理氣相沉積(PVD)及其等效物。可以在半導體層120與晶圓基板10之間插入氧化物層110。可以提供氧化物層110以防止電流洩漏。
半導體層120是在其中具有多個積體電路的半導體,並且可以大體上成形為板形。端子121可以是用於半導體層120中的多個積體電路的介面。端子121可以電連接到BEOL層130的第一再分佈層132。半導體層120可以插入氧化物層110與BEOL層130之間。
BEOL層130包含第一介電層131和第一再分佈層132。BEOL層130形成為完全覆蓋半導體層120的第一表面120a。
BEOL層130包含形成為完全覆蓋半導體層120的第一介電層131、通過光微影蝕刻工藝和/或雷射工藝形成的開放區域、以及在開放區域的暴露區域中形成的第一再分佈層132。此處,端子121可以通過開放區域暴露,並且第一再分佈層132可以形成於半導體層120和第一介電層131上以與端子121接觸或待電連接到端子121。第一再分佈層132可以各種圖案形成為電連接到半導體層120的端子121,並且可以包括多個第一再分佈層。
第一介電層131可以是選自由以下組成的群組的一種介電 層:氧化矽層、氮化矽層及其等效物,但本發明的各態樣並不限於此。可以通過以下工藝形成第一再分佈層132:針對由金、銀、鎳、鈦和/或鎢製成的晶種層的無電鍍敷工藝,使用銅等的電鍍工藝,以及使用光阻劑的光微影蝕刻工藝,但本發明的各態樣並不限於此。
另外,第一再分佈層132可以不僅由銅製成,而且還由選自由以下組成的群組的一種材料製成:銅合金、鋁、鋁合金、鐵、鐵合金及其等效物,但本發明的各態樣並不限於此。此外,可以反復地多次執行形成第一介電層131和第一再分佈層132的工藝,由此完成具有多層結構的BEOL層130。在一個實例中,第一再分佈層132可以包括通過第一介電層131的開放區域暴露的接合墊。另外,BEOL層130是通過製造(FAB)工藝形成的再分佈層。特別地,可以精細線寬或厚度形成第一再分佈層132。
如圖2B中所示,在背面研磨過程中(S2),可以通過研磨晶圓基板10的第二表面10b移除所述第二表面10b,所述第二表面與在上面形成氧化物層110、半導體層120和BEOL層130的第一表面10a相反。可以切割晶圓基板10以產生個別半導體晶片100x,並且接著研磨所述晶圓基板使其保留預定厚度以有助於處理。保留的晶圓基板10的預定厚度可以相當於在移除晶圓基板過程中(S5)通過蝕刻移除的晶圓基板10的厚度,下文將進行描述。
如圖2C中所示,在切割過程中(S3),切割將氧化物層110、半導體層120和BEOL層130堆疊在其上的晶圓基板10,以將晶圓基板10劃分為個別半導體晶片100x。也就是說,在切割過程中(S3),切割半導體層120以接著將其劃分為包含個別半導體晶粒120的個別半導體晶片100x (在整個說明書中,可互換地使用並且通過相同的元件符號標示不同的術語,例如,半導體層和半導體晶粒。)另外,由於通過切割分隔開半導體晶片100x,晶圓基板10、氧化物層110、半導體晶粒120和BEOL層130的外側表面可以置於同一平面上。可以通過刀片切割或使用切割器械執行切割,但本發明的各態樣並不限於此。半導體晶粒120可以是射頻(RF)裝置。
如圖2D中所示,在安裝半導體晶片過程中(S4),可以將多個個別半導體晶片100x彼此間隔開地安裝在載體20上。載體20具有平面的第一表面20a和與第一表面20a相反的第二表面20b,並且個別半導體晶片100x可以安裝在載體20的第一表面20a上,彼此間隔開預定距離。此處,可以翻轉相應半導體晶片100x,使得BEOL層130被引至與載體20的第一表面20a接觸且接著安裝在所述載體上。載體20可以由選自由以下組成的群組的一種材料製成:矽、低級矽、玻璃、碳化矽、藍寶石、石英、陶瓷、金屬氧化物、金屬及其等效物,但本發明的各態樣並不限於此。
如圖2E中所示,在移除晶圓基板過程中(S5),從多個半導體晶片100x移除晶圓基板10,由此使氧化物層110向外暴露。也就是說,移除晶圓基板10,使得氧化物層110的第一表面110a向外暴露。在移除晶圓基板過程中(S5),可以通過乾式和/或濕式蝕刻工藝完全移除保留的晶圓基板10。可以此方式移除晶圓基板10,由此防止晶圓基板10出現功率損失。
如圖2F和2G中所示,在囊封過程中(S6),通過囊封物140囊封安裝在載體20上的多個半導體晶片100x以及載體20的第一表面20a,以便完全覆蓋所述多個半導體晶圓和所述第一表面。囊封物140形成為完 全覆蓋載體20的第一表面20a、氧化物層110、半導體晶粒120以及BEOL層130。也就是說,囊封物140形成於載體20的第一表面20a上,以完全覆蓋安裝在載體20的第一表面20a上的個別半導體晶片100x。囊封物140具有平面的第一表面140a以及與第一表面140a相反且與載體20的第一表面20a接觸的第二表面140b。彼此間隔開的多個半導體晶片100x可以通過囊封物140電保護以防止受外部環境影響。
可以通過選自由以下組成的群組的一種方法執行囊封(S6):一般傳遞模塑法、壓縮模塑法、注射模塑法及其等效物,但本發明的各態樣並不限於此。囊封物140可以是一般環氧樹脂、薄膜、糊狀物及其等效物,但本發明的各態樣並不限於此。
另外,在形成囊封物140之後,移除載體20以使被引至與載體20的第一表面20a接觸的BEOL層130的第二表面130b以及囊封物140的第二表面140b向外暴露。
如圖2H中所示,在形成再分佈層過程中(S7),再分佈層150形成為覆蓋BEOL層130的第二表面130b和囊封物140的第二表面140b,以便電連接到向外暴露的BEOL層130。再分佈層150包含第二介電層151和第二再分佈層152。
通過形成覆蓋BEOL層130的第二表面130b和囊封物140的第二表面140b的第二介電層151、通過光微影蝕刻工藝和/或雷射工藝形成開放區域、以及在通過開放區域向外暴露的區域中形成第二再分佈層152,形成再分佈層150。此處,BEOL層130的第一再分佈層132通過開放區域暴露。另外,第二再分佈層152可以形成於BEOL層130的第二表面 130b上以被引至與通過開放區域向外暴露的第一再分佈層132接觸並電連接到所述第一再分佈層。另外,電連接到第一再分佈層132的第二再分佈層152可以延伸到囊封物140的第二表面140b。第二再分佈層152可以各種圖案形成以電連接到BEOL層130並且可以包括多個第二再分佈層。另外,再分佈層150可以形成為延伸到囊封物140的第二表面140b。可以通過改變半導體晶粒120的接合墊121的位置或改變輸入/輸出(I/O)墊的數目來形成再分佈層150。此外,由於再分佈層150形成為延伸到囊封物140的第二表面140b,因此可以通過增加用於形成I/O墊的區域而容易地增加I/O墊的數目。
第二介電層151可以是選自由以下組成的群組的一種介電層:氧化矽層、氮化矽層及其等效物,但本發明的各態樣並不限於此。第二介電層151可以防止在第二再分佈層152中的每一個之間的電短路。可以通過以下工藝形成第二再分佈層152:針對由金、銀、鎳、鈦和/或鎢製成的晶種層的無電鍍敷工藝,使用銅等的電鍍工藝,以及使用光阻劑的光微影蝕刻工藝,但本發明的各態樣並不限於此。
另外,第二再分佈層152可以不僅由銅製成,而且還由選自由以下組成的群組的一種材料製成:銅合金、鋁、鋁合金、鐵、鐵合金及其等效物,但本發明的各態樣並不限於此。第二再分佈層152可以暴露於再分佈層150的第二表面150b。此外,可以反復地多次執行形成第二介電層151和第二再分佈層152的工藝,由此完成具有多層結構的再分佈層150。
如圖2I中所示,在形成導電凸塊過程中(S8),多個導電凸塊160形成為與暴露於再分佈層150的第二表面150b的多個第二再分佈層 152接觸或電連接到所述多個第二再分佈層。導電凸塊160通過再分佈層150和BEOL層130電連接到半導體晶粒120。導電凸塊160可以包含導電填料、銅填料、導電球、焊料球或銅球,但本發明的各態樣並不限於此。
當半導體裝置100安裝在例如底板等外部裝置上時,導電凸塊160可以用作在半導體裝置100與外部裝置之間的電連接裝置。
如圖2J中所示,在單一化過程中(S9),切割囊封物140和再分佈層150以將其劃分為具有一個或多個半導體晶粒120的個別半導體裝置100。
半導體裝置100可以通過增加用於形成I/O墊的區域而容易地增加I/O墊的數目,使得再分佈層150形成為延伸到囊封物140的第二表面140b。另外,半導體裝置100可以從氧化物層110完全移除保留的晶圓基板,由此防止電流洩漏並且減少功率損失。
參考圖3,示出了流程圖,所述流程圖示出根據本發明的另一實施例的半導體裝置的製造方法。
圖3中示出的半導體裝置(200)的製造方法包含:準備晶圓(S1)、背面研磨(S2)、切割(S3)、安裝半導體晶片(S4)、移除晶圓基板(S5)、氧化(S5a)、囊封(S6)、形成再分佈層(S7)、形成導電凸塊(S8)以及單一化(S9)。
圖3中示出的準備晶圓(S1)、背面研磨(S2)、切割(S3)、安裝半導體晶片(S4)以及移除晶圓基板(S5)與圖1和2A到2E中示出的半導體裝置100的製造方法的對應步驟相同。因此,以下描述將集中於氧化(S5a)、囊封(S6)、形成再分佈層(S7)、形成導電凸塊(S8)以及單 一化(S9)的步驟。
參考圖4A到4F,橫截面圖示出了圖3中所示的半導體裝置(200)的製造方法,包含氧化(S5a)、囊封(S6)、形成再分佈層(S7)、形成導電凸塊(S8)以及單一化(S9)的各個步驟。在下文中,現將參考圖4A到4F描述圖3中所示的半導體裝置(200)的製造方法。
如圖4A中所示,在氧化(S5a)過程中,對從其上移除晶圓基板10的多個半導體晶片100x進行氧化,由此在氧化物層110和半導體晶粒120的外表面上形成額外氧化物層211。作為氧化的結果,額外氧化物層211可以在由氧化矽製成的氧化物層110的第一表面110a和外側表面110c上以及在半導體晶粒120的外側表面110c上形成為預定厚度。因此,通過氧化形成的額外氧化物層211可以與半導體晶圓110x的氧化物層110一體地形成。也就是說,氧化物層210包含半導體晶圓110x的氧化物層110以及通過氧化形成的額外氧化物層211,並且形成為完全覆蓋半導體晶粒120的第一表面120a和外側表面120c。覆蓋半導體晶粒120的第一表面之氧化物層210的厚度比覆蓋半導體晶粒120的外側表面之氧化物層210的厚度還厚。
如圖4B和4C中所示,在囊封過程中(S6),通過囊封物140囊封安裝在載體20上的多個半導體晶片200x以及載體20的第一表面20a,以便完全覆蓋所述多個半導體晶圓和所述第一表面。囊封物140形成為完全覆蓋載體20的第一表面20a、氧化物層210以及BEOL層130。也就是說,囊封物140形成於載體20的第一表面20a上,以完全覆蓋安裝在載體20的第一表面20a上的個別半導體晶片200x。囊封物140具有平面的第一表面 140a以及與第一表面140a相反且與載體20的第一表面20a接觸的第二表面140b。彼此間隔開的多個半導體晶片200x可以通過囊封物140電保護以防止受外部環境影響。
可以通過選自由以下組成的群組的一種方法執行囊封(S6):一般傳遞模塑法、壓縮模塑法、注射模塑法及其等效物,但本發明的各態樣並不限於此。囊封物140可以是一般環氧樹脂、薄膜、糊狀物及其等效物,但本發明的各態樣並不限於此。
另外,在形成囊封物140之後,移除載體20以使被引至與載體20的第一表面20a接觸的BEOL層130的第二表面130b以及囊封物140的第二表面140b向外暴露。
如圖4D中所示,在形成再分佈層過程中(S7),再分佈層150形成為覆蓋BEOL層130的第二表面130b和囊封物140的第二表面140b,以便電連接到向外暴露的BEOL層130。再分佈層150包含第二介電層151和第二再分佈層152。用於形成再分佈層150的工藝可以與圖2H中所示的形成再分佈層(S7)相同。
如圖4E中所示,在形成導電凸塊過程中(S8),多個導電凸塊160形成為與暴露於再分佈層150的第二表面150b的多個第二再分佈層152接觸或電連接到所述多個第二再分佈層。用於形成導電凸塊160的工藝可以與圖2I中所示的形成導電凸塊(S8)相同。
如圖4F中所示,在單一化過程中(S9),切割囊封物140和再分佈層150以將其劃分為具有一個或多個半導體晶粒120的個別半導體裝置200。
半導體裝置200可以通過增加用於形成I/O墊的區域而容易地增加I/O墊的數目,使得再分佈層150形成為延伸到囊封物140的第二表面140b。另外,半導體裝置200可以從氧化物層210完全移除保留的晶圓基板並且完全覆蓋半導體晶粒120,由此防止電流洩漏並且減少功率損失。
