Description

多層布線基板,堆疊結構感測器封裝,及堆疊結構感測器封裝之製造方法
本發明係關於一種多層布線基板、一種堆疊結構感測器封裝及一種堆疊結構感測器封裝之製造方法,其等應用於一影像感測器及類似物中。
日本未審查專利申請公開案第2002-353427號提議一種影像感測器之堆疊結構感測器封裝。
圖1圖解說明如在日本未審查專利申請公開案第2002-353427號中揭示之影像感測器的堆疊結構感測器封裝。
在圖1中之一感測器封裝結構中,一框形第二基板2結合至一第一基板1之一第一表面上,藉此形成一空腔3。
一積體電路4安裝於空腔3中之第一基板1的第一表面上,且一影像感測器晶片5結合至第二基板2上。如此,形成堆疊結構感測器封裝。
但是,上述結構受限於其中在由第一基板1及第二基板2形成空腔3之後結合積體電路4的一層疊製程。此具有以下缺點。
因在相同處理步驟中之層疊係必要的,所以會限制一製造位置。
此外,故障之發生引起一高處理成本。詳細而言,當在製造期間(例如在密封影像感測器期間)發生一故障時,由於該故障,所以得處理掉堆疊結構感測器封裝之所有組件。
當上述堆疊結構感測器封裝係由第一基板1之一後表面上的一接合端子結合至另一結構時,該堆疊結構感測器封裝通常係焊接至一有機基板。但是,因為一接合區域限定於底表面,所以可存在有關連接強度之一問題。
此外,因感測器及用於處理感測器信號之積體電路4已封裝,所以用於實現一額外功能之一組件係額外地放置於該封裝之外側。此與小型化相矛盾。
期望提供一多層布線基板、一堆疊結構感測器封裝及製造該堆疊結構感測器封裝之一方法,其等可使一感測器組件甚至在製造期間發生一故障時仍可再用、改良該感測器組件之連接強度及使得該結構小且薄。
根據本發明之一實施例的一多層布線基板具有從一第一表面穿透至一第二表面的一通孔,且該多層布線基板包含一電連接端子,該電連接端子形成於該第一表面及該第二表面之至少一者上之一內邊緣部分(其係該通孔之一週邊)、一外邊緣部分(其係該基板之一外週邊)及一非邊緣部分的至少一者中。該電連接端子具有一堡狀結構,其並不穿透至相對於一形成表面之一表面。
根據本發明之另一實施例的一堆疊結構感測器封裝包含:具有一通孔之一多層布線基板,該多層布線基板包含一第一表面上之一線接合墊及一第二表面上之一電連接端子,該電連接端子係形成於一內邊緣部分(其係該通孔之一週邊)、一外邊緣部分(其係該基板之一外週邊)及一非邊緣部分的至少一者中;一影像感測器,其係固定至該多層布線基板之該第一表面上之該通孔的該週邊處以橫跨該多層布線基板之該通孔放置,且該影像感測器藉由一電線而電連接至該墊;一框架,其係固定至該多層布線基板之該第一表面上的該外邊緣部分以圍繞該影像感測器;及一光學濾光器,其係固定至該框架之一表面,以面向該影像感測器。
一種根據本發明之又一實施例之製造一堆疊結構感測器封裝的方法包含以下步驟:將一影像感測器固定至一多層布線基板之一第一表面上之一通孔的一週邊以橫跨該多層布線基板之該通孔放置,該多層布線基板具有該通孔且包含該第一表面上之一線接合墊及一第二表面上之一電連接端子,該電連接端子係形成於一內邊緣部分(其係該通孔之該週邊)、一外邊緣部分(其係該基板之一外週邊)及一非邊緣部分的至少一者中;藉由一電線而電連接該多層布線基板之該墊與該影像感測器;將一框架固定至該多層布線基板之該第一表面上的該外邊緣部分以圍繞該影像感測器;及將一光學濾光器固定至該框架之一表面以面向該影像感測器。

如隨後所描述,相較於(例如)在任一邊緣部分中不提供電極之例,因為此等電極之每一者具有一堡狀結構,所以可增加電極之數量及可增強抵抗熱衝擊及類似物之焊接連接強度。

該多層布線基板11G具有一有效形狀,在該多層布線基板11G結合至另一多層布線基板時其用於最小化一安裝區域的。
在多層布線基板11G中,雖然連接強度小於第一至第六結構實例之連接強度,但可增加內部電極之數量。
下文將相對於圖9中之多層布線基板11G檢驗圖6中之多層布線基板11D及圖3中之多層布線基板11A之每一者中的電極數量及抵抗熱衝擊之焊接強度。
圖10相對於圖9中之多層布線基板顯示圖6及圖3中之多層布線基板之每一者中的電極數量及所量測之抵抗熱衝擊之焊接強度的一結果。
在圖10中,連接強度指示為一測試片之一實際量測值對圖9中之多層布線基板11G之一實際量測值的一比率,圖9中之多層布線基板11G之一實際量測值係設定為1來作為參考(參考型樣)。
在此例中,圖6中之多層布線基板11D之連接強度係作為參考型樣之圖9中之多層布線基板11G的連接強度的1.71倍。
圖3中之多層布線基板11A之連接強度係作為參考型樣之圖9中之多層布線基板11G的連接強度的1.64倍。
與此同時,當圖9中之多層布線基板11G中之電極數量為40時,圖6中之多層布線基板11D中的電極數量為56,其為作為參考型樣之圖9中之多層布線基板11G的電極數量的1.4倍。
圖3中之多層布線基板11A中的電極數量為56,其為作為參考型樣之圖9中之多層布線基板11G的電極數量的1.4倍。
如上文所描述,在根據此實施例之多層布線基板11及11A至11F中,從第一表面(前表面)111穿透至第二表面(後表面)112之通孔113係形成於中央部分中。
在該多層布線基板11中,一電連接端子(電極)形成於第一表面111及第二表面112之至少一者上之內邊緣部分IEP(其係通孔113之週邊)、外邊緣部分OEP(其係基板自身之外週邊)及非邊緣部分的至少一者中。
在多層布線基板11中,形成於內邊緣部分IEP及外邊緣部分OEP之至少一者中的電連接端子(電極)具有一堡狀(凹陷)結構,該堡狀結構並不穿透至(並不到達)相對於一形成表面的一表面。
因此,多層布線基板11及11A至11F可改良連接至另一基板及類似物之強度且亦可增加電極之數量(端子之數量)。
而且,多層布線基板11G可在結合至另一多層布線基板時最小化該安裝區域。
使用具有上述特徵之多層布線基板11及11A至11G之任一者的圖2中的堆疊結構感測器封裝10容許一感測器組件甚至在製造期間發生一故障時仍可再使用、改良該感測器組件之連接強度及使得該結構小且薄。
圖11A至圖11D圖解說明圖2中之堆疊結構感測器封裝10的一製造方法。
下文將參考圖11A至11D描述圖2中之堆疊結構感測器封裝10的製造方法。
首先,如在圖11A中所圖解說明,影像感測器12藉由一黏著劑15固定至多層布線基板11之表面,該多層布線基板11具有通孔113及包含第一表面(前表面)111上之線接合墊PAD及用於連接至第二表面(後表面)112上之另一基板的電極IEL、OEL及CTEL的至少任一者。
接下來,如圖11B中所圖解說明,影像感測器12及多層布線基板11之墊PAD係藉由一電線16而電連接。
其後,如在圖11C中所圖解說明,框架13藉由一黏著劑17固定至多層布線基板11之第一表面(前表面)111,以圍繞影像感測器12。
隨後,如在圖11D中所圖解說明,光學濾光器14藉由一黏著劑18接合至由陶瓷、樹脂或類似物形成之框架13的一表面且密封在一起。
此完成作為一影像感測器組件之圖2中之堆疊結構感測器封裝10的製造。
以此方式製造之圖2中之堆疊結構感測器封裝10容許一感測器組件甚至在製造期間發生一故障時仍可再使用、改良該感測器組件之連接強度及使得該結構小且薄。
<2.另一實施例>
圖12圖解說明根據本發明之另一實施例之一多層布線基板應用於其中的一堆疊結構感測器封裝的一結構實例。
根據其他實施例之一堆疊結構感測器封裝10A在以下點不同於根據先前描述之實施例的感測器封裝10。
在堆疊結構感測器封裝10A中,其上安裝電子裝置(諸如一積體電路21)及一電子組件22(諸如一電阻器)的一有機多層基板20藉由焊料24在上述連接端子(電極)處連接至多層布線基板11之第二表面(後表面)112。
在製造先前描述之圖2中之感測器封裝10之後,經由以下製程形成堆疊結構感測器封裝10A。
將積體電路21及電子組件22安裝於除了多層布線基板11之外的有機多層基板20上,安裝感測器封裝10以覆蓋該積體電路21及該電子組件22,且同時焊接該感測器封裝10及該有機多層基板20以獲得具有堆疊結構之感測器封裝10A。
上文已描述根據實施例之堆疊結構感測器封裝10及10A。
在上文描述中,圖3至圖9僅圖解說明電極配置實例,且可根據預期用途改變電極數量、電極之間的間距及電極大小。
而且,可根據預期用途改變多層布線基板11及通孔113之形狀。
多層布線基板11可為一有機基板及一無機基板之任一者。
在多層布線基板11中之電極電鍍可為銅圖案化、鍍金或抗鏽的。
此外,安裝於根據實施例之半導體裝置下之組件可為一主動組件及一被動組件的任一者。
如上文所描述,根據實施例,具有通孔113之多層布線基板11用於感測器組件中。
結果,當在一各別之程序中將一感測器封裝操作所必需之感測器組件與電子組件及積體電路封裝在一起時,可將該電子組件及該積體電路放置於該感測器組件之下。
而且,可藉由堆疊結構感測器封裝之製造方法達成以下效果,藉由該製造方法可同時將感測器組件與此等組件焊接在一起。
藉由使用具有通孔113之多層布線基板11,連接端子不僅可設置於基板之底表面上且亦可設置於基板之外週邊及通孔之週邊中。此外,因每一端子具有一堡狀結構,所以可在焊接時形成一填角,其改良有機多層基板與感測器封裝(感測器組件)之間的結合強度。
藉由處理包含作為一組件之具有通孔113的多層布線基板11的感測器封裝,可在普通安裝設備中製造堆疊結構感測器封裝,該普通安裝設備為在任何製造位置處之製程提供通用之多功能性。
藉由處理包含作為一組件之具有通孔113的多層布線基板11的感測器封裝,可與放置於感測器下之電子組件及積體電路一起執行焊接。此使得可由一簡單程序製造堆疊結構感測器封裝。
因可焊接放置於包含具有通孔113之多層布線基板11的感測器封裝下的組件,所以不僅可使用一積體電路,亦可使用各式各樣的組件。此促成該堆疊結構感測器封裝之較大靈活性及經改良之效能。
包含具有通孔113之多層布線基板11的感測器封裝係在與放置於該感測器封裝下之電子組件及積體電路分開的一程序中製造。所以,當在該感測器組件之製造期間發生一故障時,僅該感測器組件遭受處理成本。因此,可減少在發生一故障時的處理成本。
此外,當在感測器封裝之製造期間發生一故障時,可藉由再使用感測器組件而減少處理成本。
