6係將其上面設置成平坦。上 層絕緣膜16,是使用強化(build up)基板,通常稱爲強化材, 譬如’將由纖維或塡充料等形成之補強材分散於由環氧系樹 月旨、聚亞醯胺系樹脂、BT樹脂等所形成之熱硬化性樹脂中 1276215 ' 所構成。這種情況下,纖維是爲玻璃纖維或芳香族聚醯胺纖 維等。塡充材係砂石塡充材或陶瓷系塡充材等。 在對應於柱狀電極1 2之上面中央部的部分中,上層絕 緣膜1 6及密著力提高膜1 4c設置有開口部1 7。在上層絕緣 膜16之上面設置有由銅等所形成之上層襯底金屬層18。在 上層襯底金屬層18之上面全體設置有由銅所形成之上層配 線1 9。含有上層襯底金屬層1 8的上層配線1 9之一端部,是 介由上層絕緣膜1 6的開口部1 7而連接到柱狀電極1 2之上 φ 面,另一端側是爲連接銲墊部。 在含有上層配線1 9之上層絕緣膜1 6的上面是設有由抗 錫銲劑(solder resist)等所形成之最上層絕緣膜20。對應於 上層配線1 9之連接銲墊部的部分中的最上層絕緣膜20設置 有開口部21。在開口部21內及其上方錫銲球22被設置成連 接到上層配線1 9之連接銲墊部。複數個錫銲球22,是在最 上層絕緣膜20上配置成矩陣狀。 在基板1之下面,是設有與絕緣層1 5相同的材料所形 0成之第1下層絕緣膜23。在第1下層絕緣膜23的下面,是 設有與上層絕緣膜1 6相同的材料所形成之第2下層絕緣膜 24。在第2下層絕緣膜24之下面,是設有與最上層絕緣膜 20相同的材料所形成之最下層絕緣膜25。 如上所述,該半導體裝置在半導體構成體2及覆蓋其周 側面的絕緣層15之間設有密著力提高膜14a,因此可用來加 大由矽基板4及覆蓋其周側面的預浸料坯材形成之絕緣膜 1 5之間的密著力,又,可用來加大由環氧系樹脂等所形成之 1276215 * 密封膜1 3及由覆蓋其周側面之預浸料坯材所形成之絕緣膜 — 1 5之間的密著力。 其結果,可用來抑制矽基板4及覆蓋其周側面的絕緣層 1 5之間的熱應力或機械應力所引起的剝離,又,可用來抑制 密封膜1 3及覆蓋其周側面的絕緣層1 5之間的熱應力或機械 應力所引起之剝離。 又,在基板1之上面介由密著力提高膜1 4b設有絕緣層 1 5,因此可加大基板1與覆蓋其上面的絕緣層1 5之間的密 φ 著力。其結果,可抑制基板1及覆蓋其上面的絕緣層15之 間的熱應力或機械應力所引起之剝離。 又,在半導體構成體2之上面介由密著力提高膜14c設 有上層絕緣膜16,因此可加大由環氧系樹脂等所形成之密封 膜1 3及由覆蓋其上面的強化材料所形成之上層絕緣膜1 6之 間的密著力。其結果,可抑制密封膜1 3及覆蓋其上面的上 層絕緣膜1 6之間的熱應力或機械應力所引起之剝離。 在此處,將基板1之尺寸作成比半導體構成體2的尺寸 φ加大某程度,是因應於矽基板4上之連接銲墊5的數量之增 加,而將錫銲球22之配置領域加大到比半導體構成體2的 尺寸更大某個程度,因而將上層配線1 9之連接銲墊部(最 上層絕緣膜20的開口部2 1內之部分)的尺寸及間距作成比 柱狀電極1 2之尺寸及間距更大之故。 因此,配置成矩陣狀之上層配線1 9的連接銲墊部,不 僅對配置在應於半導體構成體2之領域,而且亦配置在對應 於半導體構成體2的周側面之外側所設置的絕緣層1 5之領 -10- 1276215 域上。亦即,配置成矩陣狀的錫銲球2 2之中’至少最外周 的錫銲球2 2是配置成比半導體構成體2位於更外側之周圍。 其次,將對該半導體裝置之製造方法的一例加以說明’ 首先,將對半導體構成體2之製造方法的一例加以說明。這 種情形,首先,如第2圖所示,準備:在晶圓狀態之砂基板 (半導體基板)4上設置有由鋁系金屬等所形成之連接銲墊 5,由氧化矽等所形成之絕緣膜6及由環氧系樹脂或聚亞醯 胺系樹脂等所形成之保護膜8,使連接銲墊5之中央部介由 φ 絕緣膜6及保護膜8上所形成的開口部7、9而露出。上述 中,在晶圓狀態之矽基板4,是在形成各半導體構成體的領 域上形成預定功能之積體電路,而連接銲墊5係分別電性連 接到對應的領域所形成之積體電路。 其次,如第3圖所示,含有介由兩開口部7、9而露出 之連接銲墊5的上面之保護膜8的上面全體上,形成有襯底 金屬層10。這種情況,襯底金屬層1〇可爲僅藉由無電解電 鍍所形成的銅層,亦可爲僅由濺鑛所形成之銅層,又亦可藉 φ由濺鍍在所形成的鈦等之薄膜層上,以濺鍍來形成銅層。 其次,在襯底金屬層10之上面來形成電鍍保護膜 (plating resist)31之圖形。這種情況下,在對應於配線11 形成領域的部分中之電鍍保護膜3 1上形成有開口部32。其 次,藉著將襯底金屬層1 〇作爲電鍍電流路徑而進行銅的電 解電鍍,在電鍍保護膜31之開口部32內的襯底金屬層10 之上面形成配線1 1。其次,將電鍍保護膜3 1剝離。 其次,如第4圖所示,在含有配線1 1的襯底金屬層10 1276215 β 之上面來形成電鍍保護膜31之圖形。這種情況下,在對應 ^ 於柱狀電極1 2之形成領域的部分中之電鍍保護膜3 3上形成 有開口部34。其次,藉著將襯底金屬層1 0作爲電鍍電流路 徑而進行銅電解電鍍,而在電鍍保護膜33之開口部34內的 配線1 1之連接銲墊部上面形成柱狀電極1 2。其次,將電鍍 保護膜3 3剝離,接著,將配線1 1作爲遮罩而將襯底金屬層 1 〇的不要部分蝕刻並加以除去,則如第5圖所示,僅在配線 11下殘留有襯底金屬層10。 φ 其次,如第6圖所示,利用網版印刷法、旋塗法、刮塗 法等,將由環氧系樹脂或聚亞醯胺系樹脂等所形成之密封膜 13使其厚度比柱狀電極12的高度更厚的方式形成在含有柱 狀電極1 2及配線1 1的保護膜8之上面全體。因此,這種狀 態下,柱狀電極1 2之上面是由密封膜1 3所覆蓋。 其次,適當地硏磨密封膜1 3及柱狀電極1 2之上面側, 如第7圖所示,使柱狀電極12之上面露出,並且將含有該 露出的柱狀電極1 2之上面的密封膜1 3之上面予以平坦化。 馨在此處,適當地硏磨柱狀電極1 2之上面側,是因爲由電解 電鍍形成柱狀電極1 2的高度有誤差,爲了消除該誤差,因 而欲將柱狀電極1 2之高度形成均勻之故。 其次,如第8圖所示,在矽基板4之下面全體形成黏著 層3。黏著層3,是由市售的環氧系樹脂、聚亞醯胺系樹脂 等之黏晶材作爲黏晶薄0吴(die attachment film)而構成者,藉 由加熱加壓而在半硬化的狀態下固定於矽基板4上。其次, 將固定於矽基板4上之黏著層3貼合於切割膠帶(未圖示), -12- 1276215 * 經過第9圖所示切割製程之後’從切割膠帶剝離時’則在矽 ^ 基板4的下面可獲得複數個具有黏著層3之半導體構成體2。 其次,將說明使用以此方式所獲得之半導體構成體2, 而製造第1圖所示之半導體裝置的情況之一例。首先,如第 10圖所示,準備具有可形成複數個第1圖所示之完成的半導 體裝置之面積的基板1。雖然基板1並無限定的意義,譬如, 可爲平面方形。基板1是在玻璃布等所形成之基材上含浸由 環氧系樹脂等所形成之熱硬化性樹脂,使熱硬化性樹脂硬化 Φ 後形成薄板狀者。 其次,在基板1之上面的預定複數部位上分別黏著在半 導體構成體2的矽基板4之下面所黏著的黏著層3。於此之 黏著,是藉由加熱加壓使黏著層3硬化。其次,如第1 1圖 所示,在半導體構成體2的周側面,在其周圍中之基板1的 上面及半導體構成體2的上面連續地形成有由矽烷偶合劑所 形成的密著力提高膜14a、14b、14c。 密著力提高膜14a、14b、14c之形成方法,是以網版印 鲁刷法、凹版輪轉印刷法、噴霧印刷法、凸版印刷法、噴墨印 刷法、旋塗法、刮塗法、細縫塗布法(slit coating)、網眼塗 布法、浸漬塗布法、CVD法(化學氣相沈積法)等其中之一 皆可。砂院偶合劑方面,可爲原液,或者亦可爲以有機溶劑 (較佳是乙醇系)或水等稀釋者。 矽烷偶合劑方面,是γ-( 2-氨乙基)氨丙基甲氧基矽烷、 γ- ( 2-氨乙基)氨丙基乙氧基矽烷、γ一( 2-氨乙基)氨 丙基二甲基氧基矽烷、氨基矽烷、γ一甲基丙烯醯氧基丙基三 1276215 甲氧基石夕院、γ-甲基丙嫌醯氧基丙基二甲基氧基砍院、γ一甲

面的密著力提高膜14a之周圍中的基板1之上面所設的密著 力提高膜1 4b之上面,將格子狀的3片絕緣層形成用薄板1 5 a 以銷等(未圖示)來定位並配置成積層,又在其上面配置上 層絕緣膜形成用薄板1 6 a。又,將與絕緣層形成用薄板1 5 a 相同材料所形成之第1下層絕緣膜形成用薄板2 3 a及與上層 -1 4- 1276215 * 絕緣膜形成用薄板1 6 a相同材料所形成之第2下層絕緣膜 形成用薄板24 a積層並配置在基板1之下面。 格子狀之絕緣層形成用薄板1 5 a,是在由玻璃布等所形 成之基材上含浸由環氧系樹脂等所形成之熱硬化性樹脂,將 熱硬化性樹脂作成半硬化狀態(B階段)下形成薄板狀的預 浸料坯材上,利用沖壓、或鑽頭或銑床加工等,可獲得形成 複數個方形之開口部3 5。上層絕緣膜形成用薄板1 6 a,雖 然並無限定的意義,但以薄板狀之強化材料爲較佳,該強化 •材料方面,係最初,由環氧系樹脂等所形成之熱硬化性樹脂 中使二氧化矽塡充料混入,而將熱硬化性樹脂作成半硬化狀 態者。 於此,絕緣層形成用薄板1 5 a之開口部3 5的尺寸是比 半導體構成體2之尺寸形成稍大。因此,絕緣層形成用薄板 1 5 a及設於半導體構成體2的周側面之密著力提高膜1 4a之 間形成有間隙36。又,3片的絕緣層形成用薄板1 5a之合計 厚度,是比含有密著力提高膜14c之半導體構成體2的厚度 •更厚某程度,如後述,當被加熱加壓時,形成可充分塡埋間 隙3 6程度之厚度。 這種情況下,絕緣層形成用薄板15a方面,雖然是使用 同樣厚度之薄板,但亦可使用厚度不同的薄板。又,絕緣層 形成用薄板,如上述,雖然可爲2層,但亦可爲1層或4層 以上。還有,上層絕緣膜形成用薄板16 a之厚度,第1圖 中,係爲對應於該形成上層絕緣膜1 6厚度的厚度或比其稍 厚之厚度。 -15- 1276215 其次,如第1 3圖所示,使用一對之加熱加壓板3 7、3 8 從上下來加熱加壓絕緣層形成用薄板1 5 a、上層絕緣膜形成 用薄板16 a、第1下層絕緣膜形成用薄板23 a及第2下層 絕緣膜形成用薄板24 a。於是,使絕緣層形成用薄板1 5 a中 所熔融之熱硬化性樹脂被壓出,來充塡第1 2圖所示的間隙 3 6,藉由其後之冷卻,在設於半導體構成體2之周側面的密 著力提高膜14a之周圍中的基板1之上面所設的密著力提高 膜14b之上面來形成絕緣層15。 | 又,在設於半導體構成體2之上面的密著力提高膜14c 及絕緣層15之上面形成有上層絕緣膜16。又,在基板1之 下面形成有第1下層絕緣膜23及第2下層絕緣膜24。這種 情況下,第1下層絕緣膜形成用薄板23 a是由與絕緣層形 成用薄板15a相同的材料所構成,其熱膨脹係數是相同。又, 第2下層絕緣膜形成用薄板24 a是由與上層絕緣膜形成用 薄板1 6a同樣的材料所構成,其熱膨脹係數是相同。 其結果,將絕緣層1 5之部分中以基板1作爲中心使其 φ上下之材料構成大致成爲對稱,藉由加熱加壓,使絕緣層1 5 的部分中之基板1上的絕緣層形成用薄板1 5 a及上層絕緣膜 形成用薄板1 6 a以及基板1下之第1下層絕緣膜形成用薄 板23 a及第2下層絕緣膜形成用薄板24 a在上下方向大致 對稱地進行硬化收縮,進而在基板1使產生的彎曲被減低, 不會在朝以後之製程的搬送或以後的製程中之加工精度帶 來障礙。此在後述的最下層絕緣膜形成用薄板25 a之情況 亦同樣。 -16- 1276215 又,上層絕緣膜1 6之上面,因爲藉由上側的加熱加壓 板3 7之下面所推壓,所以形成平坦面。又,第2下層絕緣 膜24的下面,是因爲藉由下側之加熱加壓板3 8的上面所推 壓,所以形成平坦面。從而,上層絕緣膜1 6之上面及第2 下層絕緣膜24的下面被平坦化,所以不要硏磨製程。 其次,如第1 4圖所示,藉由照射雷射光束之雷射加工, 而在對應於柱狀電極1 2之上面中央部的部分中之上層絕緣 膜1 6及密著力提高膜1 4c上形成開口部1 7。其次,因應於 φ需要,藉由除膠渣處理可將產生於開口部1 7內等的環氧樹 脂膠渣等除去。 其次,如第15圖所示,含有介由開口部17而露出之柱 狀電極12的上面之上層絕緣膜16的上面全體,藉由銅的無 電解電鍍等,而形成上層襯底金屬層18。其次’在上層襯底 金屬層1 8之上面來形成電鍍保護膜4 1之圖形。這種情況 下,在對應於上層配線1 9形成領域的部分中之電鍍保護膜 41上形成開口部42。 φ 其次,將襯底金屬層1 9作爲電鍍電流路藉由進行銅的 電解電鍍,在電鍍保護膜4 1之開口部42內的上層襯底金屬 層1 8之上面來形成上層配線1 9。其次,將電鍍保護膜4 1 剝離,接著,將上層配線1 9作爲遮罩而將上層襯底金屬層 1 8不要的部分蝕刻並除去,則如第1 6圖所示,僅上層配線 19下方殘留有上層襯底金屬層18。 其次,如第1 7圖所示,利用網版印制法或旋塗法等, 在含有上層配線1 9的上層絕緣膜1 6之上面來形成由錫銲抗 1276215 室劑等所形成之最上層絕緣膜2 0,又,在第2下層絕緣膜 ^ 24的下面形成由與最上層絕緣膜20同樣的材料所形成之最 下層絕緣膜25。這種情況下,在對應於上層配線1 9之連接 銲墊部的部分中之最上層絕緣膜20來形成開口部2 1。其 次,在開口部2 1內及其上方使錫銲球22形成連接於上層配 線1 9的連接銲墊部。 其次,如第1 8圖所示,在相互鄰接之半導體構成體2 間,切斷最上層絕緣膜20、上層絕緣膜1 6、絕緣層15、密 φ 著力提高膜14b、基板1、第1下層絕緣膜23、第2下層絕 緣膜24及最下層絕緣膜25之時,則可獲得複數個第1圖所 示的半導體裝置。 如以上,在以上述製造方法中,將複數個半導體構成體 2介由黏著層3配置在基板1上,並對於複數個半導體構成 體2,來一齊進行上層配線1 9及錫銲球22之形成,其後進 行切斷來獲得複數個半導體裝置,因此可使製造製程簡略 化。又,在第1 3圖所示的製造製程以後,可使複數個半導 •體構成體2與基板1 一起被搬送,因而藉此亦可使製造製程 簡略化。 於此,將對剝離強度試驗之一例加以說明。首先,如第 1 9圖所示,在矽基板4 A的上面形成由環氧系樹脂所形成之 密封膜13A,將密封膜13A之上面進行前處理(脫脂+熱水 洗+水洗),並在密封膜1 3 A的上面形成由矽烷偶合劑所形 成的密著力提高膜14A,在其上面形成由含有環氧系樹脂的 預浸料坯材所形成之絕緣層1 5 A,將設於絕緣層1 5 A之上面 -18- 1276215 的銅層B之-端部對絕緣層15A朝9〇。的方向拉伸。 這種情況下,試料方面,是準備:銅層B係在絕緣層 W之上面由疊層的銅箱所形成之試料(以下,稱爲本試料 1)、及使銅層B由在絕綠隱HA, k 、 仕絶緣層15A之上面形成的銅電鍍層所 形成之試料(以下,稱爲本試料2)。又,爲了比較,參考 第19圖並加以說明,準備不具有密著力提高膜14A,在密 封膜13A的上面形成絕緣層15A及銅層b,而且,銅層b 係由銅箔形成之試料(以下,稱爲比較試料丨)、及銅層B 修係由銅電鍍層形成之試料(以下,稱爲比較試料2 )。 又,本試料1、2中,作爲砂院偶合劑,是以異丙醇或 水來稀釋,使用3_環氧丙氧基丙基三乙氧基矽烷之濃度爲 1 · Owt%、及N-3 (氨乙基)3-氨丙基三甲氧基矽烷的濃度 爲 1 · 0 w t % 〇 而且’當進行剝離強度試驗時,比較試料1、2之情況, 雖然係在絕緣層15A及密封膜13A之間產生了剝離,但此 時的剝離強度(kN/m )爲〇,不能進行實質的測定。相對地, 鲁在本試料1、2之情況,是與矽烷偶合劑的種類無關,在絕 緣層1 5 A及密封膜1 3 A之間不會產生剝離,而在銅層B及 絕緣層15A之間產生剝離,此時的剝離強度(kN/m )爲0 · 8以上。因此,在密封膜13A及絕緣層15A之間來設有密著 力提高膜14A之時,可用來抑制由密封膜13A及絕緣層15A 之間的熱應力或機械應力所引起的剝離。 (第2實施形態) 第2 0圖是顯示本發明之第2實施形態的半導體裝置之 -19- 1276215 剖面圖。本半導體裝置中,與第1圖所示情況之大的不同點, ~ 是將由設於半導體構成體2之矽基板4下面之矽烷偶合劑所 形成之密著力提高膜5 1的下面所黏結之黏著層3,黏著在由 設於基板1的上面之矽烷偶合劑所形成之密著力提高膜52 的上面之點。 製造本半導體裝置之情況的一例,是在第7圖所示的製 程後,如第21圖所示,利用網版印刷法等’在矽基板4之 下面形成由矽烷偶合劑形成之密著力提高膜5 1。其次,將由 φ 黏晶材所形成之黏著層3予以半硬化而黏著在密著力提高膜 5 1的下面。其次,如第22圖所示,通過切割製程之時,則 可獲得複數個在矽基板4的下面具有密著力提高膜51及黏 著層3之半導體構成體2。 其次,如第23圖所示,利用網版印刷法等,在基板1 之上面來形成由矽烷偶合劑所形成之密著力提高膜52。其 次,在密著力提高膜52的上面之預定複數個部位上分別使 半導體構成體2的黏著層3半硬化來進行黏著。其次,利用 φ網版印刷法等,在半導體構成體2之周側面,其周圍中之密 著力提高膜52的上面及半導體構成體2之上面,連續地形 成由矽烷偶合劑所形成之密著力提高膜14a、14b、14c。以 下,通過與上述第1實形態的情況同樣之製程時,則可獲得 複數個第20圖所示的半導體裝置。 接著,依此方式所獲得的半導體裝置,是具有與上述第 1實施形態之情況同樣的效果之外,將矽基板4與由黏晶材 所形成之黏著層3之間的密著力,可經由設於其間之密著力 -20- 1276215 ' 提高膜5 1而予以加大,又,將作爲印刷基板而使用的材料 所形成之基板1與由黏晶材所形成之黏著層3之間的密著 力,經由設於其間之密著力提高膜51予以加大。其結果’ 可抑制矽基板4及黏著層3之間的熱應力或機械應力所引起 之剝離,又,可抑制基板1及黏著層3之間的熱應力或機械 應力所引起之剝離。 (第3實施形態) 第24圖係顯示本發明之第3實施形態的半導體裝置剖 φ面圖。本半導體裝置中,與第20圖所示情況不同點,是第 2〇圖中僅將設於半導體構成體2之上面上的密著力提高膜 14c,作爲對應於上層絕緣膜16之下面全面的密著力提高膜 53而設置,而進一步加大半導體構成體2及絕緣層15之上 面以及上層絕緣膜1 6之間的密著力之點。 製造本半導體裝置之情況的一例,是在第23圖所示的 製程後,如第25圖所示,利用網版印刷法等,在設於半導 體構成體2之周側面的密著力提高膜1 4a之周圍中的基板1 •之上面所設置的密著力提高膜14b之上面,將格子狀的3片 絕緣層形成用薄板1 5a以銷等(未圖示)定位並配置成積層。 又,在基板1之下面配置由與絕緣層形成用薄板1 5a同樣之 材料所形成之第1下層絕緣膜形成用薄板23a。 其次,如第26圖所示,使用一對之加熱加壓板37、38 從上下來加熱加壓絕緣層形成用薄板1 5a及第1下層絕緣膜 形成用薄板23a。於是,使絕緣層形成用薄板15a中所熔融 之熱硬化性樹脂被壓出,在設於半導體構成體2的周圍中之 -21 - 1276215 基板1的上面之密著力提高膜14b的上面來形成絕緣層15。 又,在基板1之下面形成第1下層絕緣膜23。 其次,爲了除去多餘的熱硬化性樹脂並平坦化,而進行 拋光硏磨,以完全地除去設於半導體構成體2之上面的密著 力提高膜14c,如第27圖所示,使柱狀電極12及密封膜13 之上面露出。而,該硏磨,只要除去多餘的熱硬化性樹脂且 進行某程度之平坦化即可,不需要完全地除去設於半導體構 成體2的上面之密著力提高膜14c。 φ 其次,如第28圖所示,在設於柱狀電極1 2、密封膜1 3、 半導體構成體2的周側面之密著力提高膜14a及絕緣層15 的上面,利用網版印刷法等,形成由矽烷偶合劑所形成之密 著力提高膜53。其次,在密著力提高膜53之上面配置上層 絕緣膜形成用薄板16a。又,在第1下層絕緣膜23的下面, 配置由與上層絕緣膜形成用薄板1 6a同樣之材料所形成之第 2下層絕緣膜形成用薄板24 a。 其次,使用未圖示之一對加熱加壓板從上下來加熱加壓 上層絕緣膜形成用薄板1 6 a及第2下層絕緣膜形成用薄板 2 4 a,則在密著力提高膜5 3的上面形成上層絕緣膜1 6,又, 在第1下層絕緣膜23之下面形成第2下層絕緣膜24。這種 情況下,與上述第1實施形態的情況同樣地,不需要將上層 絕緣膜1 6之上面及第2下層絕緣膜24的下面予以平坦化所 需的硏磨製程。以下,通過與上述第1實施形態之情況的同 樣製程,可獲得複數個第24圖所示之半導體裝置。 (第4實施形態) -22- 1276215 第2 9圖係顯示本發明之第4實施形態的半導體裝置之 剖面圖。本半導體裝置中,與第1圖所示情況之大的不同點, 是將上層絕緣膜、上層配線及下層絕緣膜作成2層之點。即, 含有第1上層配線1 9 A的第1上層絕緣膜1 6 A之上面設有 由與第1上層絕緣膜1 6 A同樣的材料所形成之第2上層絕 緣膜16 B。在第2上層絕緣膜16 B的上面是設置含有第2 上層襯底金屬層18B的第2上層配線19B。 含有第1上層襯底金屬層18A之第1上層配線19A的 鲁一端部,是介由第1上層絕緣膜16 A之開口部17A而連接 於柱狀電極12的上面。含有第2上層襯底金屬層18B之第 2上層配線19B的一端部,是介由第2上層絕緣膜16 B之 開口部17B而連接於第1上層配線19A的連接銲墊部。錫銲 球22,是介由最上層絕緣膜20之開口部21而連接於第2 上層配線1 9B的連接銲墊部。 而且,爲了減低製造製程中及製造製程後之基板1的翹 曲,在第1下層絕緣膜23之下面設有由與第1上層絕緣膜 馨16 A同樣之材料所形成之第2下層絕緣膜24A,在第2下層 絕緣膜24A之下面設有與由第2上層絕緣膜16 B同樣的材 料所形成之第3下層絕緣膜24B,在第3下層絕緣膜24B之 下面設有由與最上層絕緣膜20同樣的材料所形成之最下層 絕緣膜25。而,亦可將上層絕緣膜及上層配線作成3層以上。 (其他實施形態) 上述實施形態,雖然是在相互鄰接之半導體構成體2間 進行切斷,但並不限定於此,將2個或2個以上的半導體構 -23- l2762l5 · • 成體2作爲1組來切斷,亦可獲得多晶片模組型之半導體裝 寶。這種情況下,以複數個爲1組的半導體構成體2是同種、 或不同種皆可。 又’基板1,是不僅印刷基板之核心材,亦可在核心材 的一面或兩面使銅箔等之金屬箔以全面或圖形化由所形成 的基板、銅或不銹鋼等所形成之金屬板,或玻璃板、陶瓷板 等,又,並不限於1片之構件,亦可使絕緣膜及配線交互地 積層的多層印刷電路板。 φ 又,上述實施形態,雖然是作成在基板1上將半導體構 成體2之外部連接用電極之柱狀電極1 2朝向與基板1相反 面側之面朝上接合(face-up bonding)法,但將半導體構成體 2之外部連接用電極作成朝向基板1的上面側,所謂面朝下 接合(face-down bonding)法之情況亦可適用。 [圖式簡單說明】 第1圖係本發明之第1實施例的半導體裝置之剖面圖。 第2圖係第1圖所示半導體裝置之製造方法的一例中, φ最先準備者之剖面圖。 第3圖係接續第2圖製程之剖面圖。 第4圖係接續第3圖製程之剖面圖。 第5圖係接續第4圖製程之剖面圖。 第6圖係接續第5圖製程之剖面圖。
