電子元件封裝及其製造方法
圖3是示意性地說明電子元件封裝的實例的剖視圖。根據本示例性實施例的電子元件封裝100可包括安置於所述電子元件封裝的板上的電子元件120、及電性連接至電子元件120並保護電子元件120的囊封體130。在此種情形中,所述電子元件封裝的所述板可包括配線部110作為其主要元件。
配線部110可包括絕緣層111、導電圖案112、及導電介層窗113,且可包括電性連接至電子元件120的訊號傳遞配線、及與電子元件120電性斷開的電性測試配線S。在此種情形中,訊號傳遞配線及電性測試配線S二者可包括配線部110的導電圖案112及導電介層窗113。在配線部110的導電圖案112及導電介層窗113中,包含於電性測試配線S中的配線部110的導電圖案112及導電介層窗113由導電圖案112S及導電介層窗113S表示。
電性測試配線S可包括形成於配線部110的兩個表面上的導電圖案112S、及將導電圖案112S電性連接至彼此的導電介層窗113S,且可被設置以如下所述般實行配線部110的電性測試。儘管在根據實例的電子元件封裝100中已闡述了其中配線部110具有多層結構的情形,然而若需要,則配線部110亦可由單一層形成。另外,依設計特定細節而定,配線部110亦可具有較所述單一層更多的層。
絕緣層111中所可含有的絕緣材料可為:熱固性樹脂,例如環氧樹脂;熱塑性樹脂,例如聚醯亞胺樹脂;具有例如浸入於所述熱固性樹脂及所述熱塑性樹脂中的玻璃纖維或無機填料等加強材料的樹脂,例如預浸體、味之素增層膜(Ajinomoto build-up film,ABF)、FR-4、雙馬來醯亞胺三嗪(bismaleimide Triazine,BT)等。另外,在其中使用感光成像介電物(photo-imagable dielectric,PID)作為所述絕緣材料的情形中,絕緣層111可被形成為具有進一步減小的厚度,且可更易於實作精細圖案。若需要,則在配線部110中形成相應層的絕緣層111可由相同的材料形成或可由不同的材料形成。絕緣層111的厚度亦並無特別限制。舉例而言,絕緣層111的除導電圖案112以外的厚度可為約5微米(µm)至20微米,且當慮及導電圖案112的厚度時,絕緣層111的厚度可為約15微米至70微米。
導電圖案112及112S亦可充當配線圖案及/或焊墊圖案,且例如銅(Cu)、鋁(Al)、銀(Ag)、錫(Sn)、金(Au)、鎳(Ni)、鉛(Pb)、或其合金等導電性材料可用作導電圖案112及112S的材料。導電圖案112可依對應層的設計而定實行各種功能。舉例而言,導電圖案112可充當接地(GND)圖案、電力(PWR)圖案、訊號(S)圖案等而作為重佈圖案。此處,訊號(S)圖案可包括除接地(GND)圖案、電力(PWR)圖案等以外的各種訊號,例如資料訊號等。另外,導電圖案112可充當介層窗焊墊、外部連接端子焊墊等而作為焊墊圖案。導電圖案112的厚度亦無特別限制,且可為例如約10微米至50微米。
與此同時,若需要,則可在自絕緣層111暴露至外部的導電圖案112及112S(例如,電子元件120所連接至的導電圖案112及112S)上進一步形成表面處理層。所述表面處理層並無特別限制,只要其為相關技術中的所習知者即可,且可藉由例如電解鍍金、無電鍍金、有機可焊性保護劑(organic solderability preservative,OSP)、或無電鍍錫、無電鍍銀、無電鍍鎳/置換鍍金(substituted gold plating)、直接浸金(direct immersion gold,DIG)鍍覆、熱空氣焊料均塗(hot air solder leveling,HASL)等而形成。
導電介層窗113及113S可將在不同的層上形成的導電圖案112及112S、電極焊墊121等電性連接至彼此,藉此在電子元件封裝100內形成電性路徑。例如銅(Cu)、鋁(Al)、銀(Ag)、錫(Sn)、金(Au)、鎳(Ni)、鉛(Pb)、或其合金等傳導材料可用作導電介層窗113及113S的材料。導電介層窗113及113S亦可被完全填充以傳導材料。作為另一選擇,可沿導電介層窗113及113S的壁形成傳導材料。另外,導電介層窗113及113S可具有相關技術中習知的所有形狀,例如其中介層窗的直徑朝下表面變小的錐形形狀、其中介層窗的直徑朝下表面變大的倒錐形形狀、圓柱形形狀等。
如上所述,所述電性測試配線S可包括配線部110的導電圖案112S及導電介層窗113S,且可以其中電性測試配線S與電子元件120電性斷開的狀態(即,以其中電性測試配線S不電性連接至電子元件120的狀態)包含於所述板中。另外,屬於電性測試配線S的導電圖案112S可與屬於所述訊號傳遞配線的導電圖案112電性斷開。包含於電性測試配線S中的導電圖案112S可形成於配線部110的兩個表面上,即,形成於圖3中配線部110的上表面及下表面上。此形式的目的可為在其中支撐架耦合至配線部110的下部部分的狀態中對配線部110的整個上部部分實行電性測試。在對以上所欲闡述的製造電子元件封裝的方法的說明中,將對此予以更詳細的闡述。
如圖3中所示,電性測試配線S的欲實行配線部110的電性測試的導電圖案中的某些導電圖案112S可形成於配線部110的下表面上,且可具有其中某些導電圖案112S不屬於屬於訊號傳遞配線的導電圖案112的形式,即,其中所述某些導電圖案112S與屬於所述訊號傳遞配線的導電圖案112斷開的形式。圖4中更詳細地示出此電性斷開結構。圖4是示意性地說明圖3中的電性測試配線的形狀的平面圖。電性測試配線S可包括具有菊鍊(daisy chain)形狀的導電圖案112S,以實行電性測試。由於採用所述菊鍊而非使用封裝來實行電性測試,因此需要在電性測試之後移除所述菊鍊。如圖4中所示,將電性測試配線S與鄰近於電性測試配線S的另一導電圖案112連接至彼此的連接部C可為導電圖案中形成於配線部110的最下表面上的一者,且可對應於將至少兩個導電介層窗113連接至彼此的測試連接圖案。連接部C可在電性測試之後斷開,藉此形成斷開區R。如此一來,可獲得不連接至電子元件120的電性測試配線S。
如在本示例性實施例中,配線部110可單獨地包括電性測試配線S,且因此可在安裝電子元件120之前對配線部110的整個上部部分實行電性測試,且可減少相對昂貴的電子元件120的不必要消耗。亦即,在根據相關技術的其中在安置電子元件120之後實行電性測試的方案中,即使缺陷是產生於所述配線部中而非所述電子元件中,仍會存在可能無法使用所述電子元件的問題。本發明人期望解決此問題。此外,即使在其中在安置所述電子元件之前實行所述電性測試的情形中,仍會因在製造配線部110的製程中所需的支撐架而難以將電性訊號施加至配線部110的上部部分及下部部分。因此,本發明人已使得即使在其中支撐架是利用上述電性測試配線S來安置的狀態中,仍能夠對配線部110的整個上部部分實行電性測試。
電子元件120可為各種主動元件(例如,二極體、真空管、電晶體等)或被動元件(例如,電感器、電容器、電阻器等)。作為另一選擇,電子元件120可為積體電路(integrated circuit,IC)晶片,積體電路晶片表示其中將數百至數百萬個或更多個組件整合於一起的晶片。若需要,則電子元件120可為其中將積體電路以覆晶(flip-chip)形式封裝的電子元件。所述積體電路晶片可為應用處理器晶片,例如中央處理器(例如,中央處理單元)、圖形處理器(例如,圖形處理單元)、數位訊號處理器、密碼學處理器、微處理器、微控制器等,但並非僅限於此。在此種情形中,儘管在圖3中示出一個電子元件120,然而亦可使用二或更多個電子元件。
電子元件120可包括電性連接至配線部110的電極焊墊121。電極焊墊121的目的可為將電子元件120電性連接至外部,且電極焊墊121的材料並無特別限制,只要其為傳導材料即可。所述傳導材料可為銅(Cu)、鋁(Al)、銀(Ag)、錫(Sn)、金(Au)、鎳(Ni)、鉛(Pb)、或其合金,但並非僅限於此。電極焊墊121可藉由配線部110而重配置,且配線部110可出於以下所欲闡述的示例性實施例中的重配置的目的而被劃分成第一配線部及第二配線部。電極焊墊121可具有嵌入形式或突出形式。另外,位於配線部110的連接至電子元件120的最上部分處的導電圖案112可具有如圖3中所示其中導電圖案112形成於絕緣層111的上表面上的形式,或具有其中導電圖案112嵌入於絕緣層111中的形式(即,其中導電圖案112不自絕緣層111突出的形式)。
在其中電子元件120為積體電路晶片的情形中,電子元件120可具有主體(未由參考編號表示)、保護層(未由參考編號表示)、及電極焊墊121。所述主體可在例如主動晶圓的基礎上形成。在此種情形中,可使用矽(Si)、鍺(Ge)、砷化鎵(GaAs)等作為主體的基材(basic material)。所述保護層可用於保護主體不受外部因素影響,且可由例如氧化物層、氮化物層等形成,或者可由氧化物層與氮化物層構成的雙層形成。例如銅(Cu)、鋁(Al)、銀(Ag)、錫(Sn)、金(Au)、鎳(Ni)、鉛(Pb)、或其合金等傳導材料可用作電極焊墊121的材料。其上形成有電極焊墊121的層可變為主動層。
電子元件120在其橫截面中的厚度並無特別限制,且依電子元件120的種類而定可有所變化。舉例而言,在其中所述電子元件為積體電路晶片的情形中,所述電子元件的厚度可為約100微米至480微米,但並非僅限於此。
與此同時,如圖3中所示,配線部110上可安置有至少一個導電柱(conductive post)131。在本示例性實施例中,已使用其中設置有多個導電柱131的結構。導電柱131可用於將被施加至電子元件封裝100的上部部分的電性訊號傳遞至配線部110,且在本示例性實施例中所述導電柱131並非必需的。如圖3中所示,所述多個導電柱131可安置於配線部110的外側處以包圍電子元件120。導電柱131可在當電子元件120上方安置有另一電子元件或藉由所述上部部分而施加外部電性訊號時充當電性連接路徑,且可含有具有高導電性的材料,例如銅、銀等。在此種情形中,如圖3中所示,導電介層窗132或導電圖案133可形成於導電柱131上方,以將電子元件120連接至安置於電子元件120上方的另一電子元件等。
囊封體130可保護電子元件120及導電柱131。舉例而言,囊封體130可囊封電子元件120及導電柱131。其中囊封體130囊封電子元件120及導電柱131的形式並無特別限制,且可為其中囊封體130包圍電子元件120的至少部分及導電柱131的至少部分的形式。此處,囊封體130包圍目標元件的含義是:囊封體130因夾置於囊封體130與所述目標元件之間的分離元件而不直接接觸所述目標元件;以及囊封體130直接覆蓋所述目標元件。
囊封體130的材料並無特別限制,只要所述囊封體可用於保護電子元件120及導電柱131即可。舉例而言,可使用以下作為囊封體130的材料:熱固性樹脂,例如環氧樹脂;熱塑性樹脂,例如聚醯亞胺樹脂;具有例如浸入於所述熱固性樹脂及所述熱塑性樹脂中的玻璃纖維或無機填料等加強材料的樹脂,例如預浸體、味之素增層膜、FR-4、雙馬來醯亞胺三嗪、感光成像介電樹脂等。另外,如下所述,可藉由在配線部110上堆疊處於非硬化狀態中的樹脂膜並接著硬化所述樹脂膜的方法來獲得囊封體130。除上述方法以外,可藉由例如使用環氧樹脂模製化合物(epoxy molding compound,EMC)的方法等習知模製方法來獲得囊封體130。
與此同時,若需要,則囊封體130可含有傳導顆粒以阻擋電磁波。舉例而言,所述傳導顆粒可為可阻擋電磁波的任意材料,例如銅(Cu)、鋁(Al)、銀(Ag)、錫(Sn)、金(Au)、鎳(Ni)、鉛(Pb)、焊料等,但並非特別限定於此。
所述電子元件封裝可更包括:外層114,安置於配線部110之下且能夠保護配線部110不受外部物理或化學影響等。在此種情形中,外層114可具有開口部,所述開口部暴露出配線部110的導電圖案112的至少部分。外層114的材料並無特別限制。舉例而言,可使用阻焊劑(solder resist)作為外層140的材料。另外,可使用與配線部110的絕緣層111相同的材料作為外層140的材料,且外層114一般而言由單一層形成,但若需要,則亦可由多個層形成。
電子元件封裝100可包括安置於電子元件封裝100的最下部分處的連接端子115。使用連接端子115的目的可為將電子元件封裝100物理地連接至及/或電性連接至外部。舉例而言,電子元件封裝100可藉由連接端子115而安裝於所述電子裝置的主板上。連接端子115可經由在外層114中形成的開口部而連接至導電圖案112。因而,連接端子115亦可電性連接至電子元件120。連接端子115可由例如銅(Cu)、鋁(Al)、銀(Ag)、錫(Sn)、金(Au)、鎳(Ni)、鉛(Pb)、焊料等傳導材料形成,但並非特別限定於此。連接端子115可為焊盤(land)、球、引腳等。連接端子115可由多個層或單一層形成。在其中連接端子115由多個層形成的情形中,連接端子115可含有銅柱及焊料,且在其中連接端子115由單一層形成的情形中,連接端子115可含有錫-銀焊料或銅。然而,此僅為實例,且連接端子115並非僅限於此。
與此同時,某些外部的連接端子115可安置於扇出區中。所述扇出區被定義為除其中安置有所述電子元件的區以外的區。亦即,根據實例的電子元件封裝100可為扇出式封裝。所述扇出式封裝可具有較扇入式封裝高的可靠性、可實作多個I/O端子、且可易於實行3D互連。另外,由於扇出式封裝相較於球柵陣列(ball grid array,BGA)封裝、焊盤柵陣列(land grid array,LGA)封裝等而言無需使用單獨的基板便可安裝於所述電子裝置上,因此所述扇出式封裝可被製造成具有減小的厚度,且可具有優異的價格競爭力。
連接端子115的數目、間距、安置形式等並無特別限制,且可由熟習此項技術者依設計特定細節而充分地進行修改。舉例而言,依電子元件120的電極焊墊121的數目而定,連接端子115的數目可為數十至數千個。然而,連接端子115的數目並非僅限於此,而是亦可為數十至數千個或更多個、或者為數十至數千個或更少個。
在下文中,將闡述根據本發明中示例性實施例的一種電子元件封裝的板及一種製造電子元件封裝的方法。藉由閱讀對製造電子元件封裝的方法的說明,可更清楚地理解根據上述示例性實施例或經修改實例的電子元件封裝的結構。
圖5至圖12是示意性地說明根據本發明中示例性實施例的用於電子元件封裝的板及製造使用所述板的電子元件封裝的方法的圖。
首先,如圖5中所示,可在支撐架160上形成配線部110。使用支撐架160的目的可為應對具有相對減小的厚度的配線部110,且支撐架160的材料並無特別限制,只要其可支撐配線部110即可。支撐架160可具有多層結構,且可包括離型層(release layer)、金屬層等,以易於在後續製程中自配線部110移除。在本示例性實施例中,可在其中支撐架160耦合至配線部110的狀態中實行配線部110的電性測試。為此,支撐架160的最上部分可由具有電性絕緣性質的材料形成。
可依所期望形狀來形成配線部110的絕緣層111、導電圖案112及導電介層窗113,且可以所需次數重複進行形成絕緣層111、導電圖案112及導電介層窗113的製程。詳言之,可藉由例如以下等習知方法來形成絕緣層111:對絕緣層111的前驅物(precursor)進行積層並接著硬化所述前驅物的方法;施加用於形成絕緣層111的材料並接著硬化所述材料的方法。可使用以下方法等作為積層所述前驅物的方法:實行在高溫下對前驅物壓製達預定時間的熱壓製製程、對所述前驅物進行減壓、並且接著將所述前驅物冷卻至室溫、在冷壓製製程中冷卻所述前驅物、並且接著分離作業工具。可使用例如利用刮板施加油墨的網版印刷方法、以霧形式施加油墨的噴霧印刷方法等作為施加所述材料的方法。所述硬化製程:其為後製程(post-process),可為將材料乾燥至不完全硬化以便使用光刻方法等的製程。
亦可藉由習知的方法來形成導電圖案112及導電介層窗113。首先,可使用上述機械鑽孔及/或雷射鑽孔形成介層窗孔(圖中未示出)。作為另一選擇,在其中絕緣層111含有感光成像介電物等的情形中,亦可藉由光刻方法來形成所述介層窗孔。亦可使用乾膜圖案藉由電解鍍銅、無電鍍銅等來形成導電圖案112及導電介層窗113。
如上所述,在本示例性實施例中,導電圖案112S及導電介層窗113S可形成電性測試配線S。然而,與最終結構不同,電性測試配線S可處於其中電性測試配線S連接至其他導電圖案112及導電介層窗113以實行配線部110的電性測試的狀態中。如圖5中所示,可在配線部110之下形成連接至電性測試配線S的所述連接部C。在其中在配線部110之下形成連接部C的情形中,在後續製程中可易於執行將電性測試配線S與電子元件120電性斷開的短路製程。
接下來,如圖6中所示,可從電性連接方面確認在配線部110中是否存在缺陷。為此,可將測試夾具161連接至配線部110上的導電圖案112。在此種情形中,測試夾具161可包括多個尖端162。可在與配線部110上的導電圖案112中的至少某些導電圖案112對應的位置處安置所述多個尖端162。
如上所述,為實行所述電性測試而設置的電性測試配線S可處於其中電性測試配線S電性連接至導電圖案112及導電介層窗113以連接至電子元件的狀態中,且可在配線部110上形成電性測試配線S的導電圖案112S。由於存在此結構,因此即使在其中電性訊號未施加至配線部110的上部部分及下部部分的情形中(即,即使在其中支撐架160耦合至配線部110的狀態中),可僅藉由安置於配線部110的上表面上的導電圖案112來實行電性測試,且可在安裝所述電子元件之前執行本測試製程。可棄用或出於另一目的而重複使用在本測試製程中被確定為不符合要求的配線部110,且不對被確定為不符合要求的配線部110實行後續製程,且因此可減少製程成本。
接下來,如圖7中所示,可在配線部110上形成具有柱形狀的導電柱131。可將導電柱131電性連接至配線部110的導電圖案112及導電介層窗113。如上所述,導電柱131可由例如銅、銀等材料形成,且可藉由恰當的鍍覆方法形成。除所述鍍覆方法以外,可使用另一方法作為形成導電柱131的方法。舉例而言,可考慮一種將具有柱形狀的結構結合至配線部110的方法。
與此同時,在形成導電柱131之後,亦可執行上述電性測試製程。亦即,在配線部110上安裝電子元件120之前,可對配線部110及導電柱131實行電性測試,以同時檢查在配線部110及導電柱131中是否產生缺陷。
接下來,如圖8中所示,可在配線部110上安置電子元件120,且可將電子元件120電性連接至配線部110。在此種情形中,電子元件120所安置的位置並無特別限制。然而,較佳地,可在配線部110上將電子元件120安置成處於不與電性測試配線S連接的狀態中。另外,在其中電性測試配線S直接位於電子元件120之下的情形中,電性測試配線S可能非所預期地連接至電子元件120。因此,較佳地,可將電子元件120所安裝於的位置加以調整,以使得電性測試配線S位於電子元件120的鄰近之處。與此同時,如上所述,可將電子元件120安置成被所述多個導電柱131包圍。為了提供穩定的安裝結構,可在電子元件120的電極焊墊121與配線部110的導電圖案112之間使用傳導黏合材料。
接下來,如圖9中所示,可形成用於囊封電子元件120及導電柱131的囊封體。可使用在配線部110上堆疊處於非硬化狀態的樹脂膜並接著硬化所述樹脂膜的方法作為形成囊封體130的方法的實例。在此種情形中,可在樹脂膜的表面(即,圖8中樹脂膜的上表面)上形成金屬薄膜。所述金屬薄膜可隨後用於形成配線圖案。可使用塗有樹脂的銅(resin coated copper,RCC)作為樹脂膜的具體實例。在形成囊封體130之後,可將導電介層窗132及導電圖案133形成為連接至導電柱131。以下將闡述形成導電介層窗132及導電圖案133的製程的詳細內容。
接下來,如圖10中所示,可將支撐架160與配線部110分離。在此種情形中,可恰當地利用相關技術中所使用的蝕刻製程、除汙製程等。另外,如上所述,可將測試連接圖案(即,連接部C)斷開,以將電性測試配線S電性隔離。將參照圖11來詳細闡述此斷開製程。
如圖11中所示,在藉由上述蝕刻製程、除汙製程等而暴露出導電圖案112之後,可形成例如乾膜光阻劑(dry film photo-resist,DFR)膜等遮罩層170。遮罩層170可具有其中將欲斷開的區開放的形式。可藉由此開放的區來蝕刻導電圖案112,以斷開所述連接部,藉此形成可將電性測試配線S電性隔離的斷開區。因此,可獲得原始預期的配線形式。
接著,可形成覆蓋導電圖案112的外層114。外層114可覆蓋包含於電性測試配線S中的導電圖案112S以使其不暴露至外部,且可具有開口部,所述開口部暴露出導電圖案112的連接至電子元件120的至少部分。
可藉由以下方法來形成外層114:對外層114的前驅物進行積層並接著硬化所述前驅物的方法;施加用於形成外層114的原材料並接著硬化所述原材料的方法。接著,可在外層114中形成開口部,且可形成參照圖3所闡述的連接端子115以填充於所述開口部中。形成連接端子115的方法並無特別限制。亦即,可依連接端子115的結構或形式而定藉由相關技術中眾所習知的方法來形成連接端子115。可藉由回焊(reflow)來固定連接端子115,可將連接端子115的部分嵌入於外層114中以增強固定力,且可將連接端子115的其餘部分暴露至外部,藉此可提高可靠性。
與此同時,作為經修改實例,如圖12中所示,可在囊封體130上安置附加電子元件140,且可形成覆蓋附加電子元件140的附加囊封體150,藉此可獲得堆疊式封裝(package-on-package,POP)結構。在下文中,為了將電子元件120與附加電子元件140彼此區分並將囊封體130與附加囊封體150彼此區分,若有必要,則電子元件120將稱作第一電子元件,附加電子元件140將稱作第二電子元件,囊封體130將稱作第一囊封體,且附加囊封體150將稱作第二囊封體。
第二電子元件140可為類似於第一電子元件120的各種主動元件或被動元件,且可為例如記憶體組件等。如上所述,第二電子元件140可電性連接至導電柱131。儘管圖12中已示出所述第二電子元件與導電柱131之間藉由導線151而進行的連接,然而所述第二電子元件與導電柱131之間藉由導線151而進行的所述連接僅為實例。亦即,可藉由另一連接方法(例如,覆晶結合方法等)來將第二電子元件與導電柱131連接至彼此。另外,儘管圖3中已示出一個電子元件120,然而亦可使用二或更多個電子元件。
與第一囊封體130類似,第二囊封體150可囊封第二電子元件140,以保護第二電子元件140。在此種情形中,如自圖12中所示形式所見,第一囊封體130與第二囊封體150可彼此接觸。詳言之,第一囊封體130的上表面與第二囊封體150的下表面可在至少局部區中彼此接觸,且藉由此結構,即使在其中使用多個電子元件的情形中,仍可獲得緊湊的封裝結構。第二囊封體150的材料並無特別限制,只要第二囊封體150可實行此功能即可。舉例而言,可利用絕緣樹脂藉由環氧樹脂模製化合物模製來形成第二囊封體150。另外,第二囊封體150亦可由與第一囊封體130相同的材料形成。此外,可藉由與形成第一囊封體130的方法相同的方法(例如,堆疊處於非硬化狀態中的樹脂膜的方法)來獲得第二囊封體150。
與此同時,可如圖12中所示在其中支撐架160耦合至配線部110的狀態中、或可在其中支撐架160與配線部110分離的狀態中執行安裝附加電子元件140的當前製程。另外,在安裝第二電子元件140之前,可藉由囊封體130上的導電圖案133來再次實行電性測試,且在其中支撐架160與配線部110分離的狀態中,可利用囊封體130上的導電圖案133及配線部110之下的導電圖案112二者來實行所述電性測試。在後續製程中,可使用上述製程,藉此恰當地完成堆疊式封裝結構。
在下文中,將闡述本發明中所提出的製造電子元件封裝的方法的另一實例。圖13至圖18是示意性地說明根據本發明中另一示例性實施例的製造電子元件封裝的方法的圖。根據本示例性實施例的製造電子元件封裝的方法與根據上述示例性實施例的製造電子元件封裝的方法的主要不同在於:使用具有不同特性的兩個配線部。然而,在上述示例性實施例中,亦可採用以下將結合製造電子元件封裝的方法來闡述的內容中並不與上述示例性實施例的技術精神相悖的技術精神。
首先,如圖13中所示,可在支撐架260上形成第一配線部210a。第一配線部210a可包括絕緣層211a、導電圖案212a(參見圖14)、及導電介層窗213a(參見圖14)。在此種情形中,第一配線部210a可包括用於實行電性測試的電性測試配線S。由於可藉由在上述示例性實施例中所闡述的方法來獲得第一配線部210a,因此將不再予以贅述。
接下來,如圖14中所示,可在第一配線部210a上形成第二配線部210b。與第一配線部210a類似,第二配線部210b可包括絕緣層211b、導電圖案212b、及導電介層窗213b,且可將用於實行電性測試的電性測試配線S形成為處於連接至第一配線部210a的狀態中。可利用相較於第一配線部210a而言更靠近電子元件安置的第二配線部210b作為重佈層。為此,包含於第二配線部210b中的導電圖案212b之間的最小間距可小於包含於第一配線部210a中的導電圖案212a之間的最小間距。為此,分別包含於第一配線部210a及第二配線部210b中的絕緣層211a及211b的材料可彼此不同。在其中第二配線部210b中需要形成精細圖案的情形中,絕緣層211b可由光可固化材料形成,以便可使用光刻製程。包含於第一配線部210a中的絕緣層211a可由與第二配線部210b的絕緣層211b的材料相同的材料形成。然而,慮及所述電子元件封裝的其他特性,包含於第一配線部210a中的絕緣層211a可由與第二配線部210b的絕緣層211b的材料不同的材料形成。舉例而言,慮及翹曲剛性(warpage rigidity)特性等,包含於第一配線部210a中的絕緣層211a可由包含預浸體或味之素增層膜的材料形成。
與此同時,與上述示例性實施例不同,在本示例性實施例中,已使用具有突出形式的電極焊墊214b。可將絕緣層211b蝕刻成具有恰當的厚度,以獲得具有突出形式的電極焊墊214b。在形成精細圖案時使用具有嵌入形式的電極焊墊可為恰當的,且在其中使用具有突出形式的電極焊墊的情形中,所述電極焊墊與所述電子元件之間的緊密黏合可得到改善。因此,若需要,則可使用具有恰當形式的電極焊墊。
接下來,儘管圖中未單獨示出,然而同樣在本示例性實施例中,如以上參照圖6所述,可對第二配線部210b的整個上部部分實行電性測試。當在本測試製程中確定在第一配線部210a及第二配線部210b中的至少一者中存在缺陷時,可不實行後續製程,且因此可提高製程效率。
如圖15中所示,可形成導電柱231。將更詳細地闡述形成導電柱231的製程。首先,可在配線部210a及210b上形成例如乾膜光阻劑膜等遮罩層280,且可移除其中欲形成導電柱的區。接著,可藉由例如鍍覆製程、濺鍍製程、施漿製程(paste applying process)等製程來填充被移除的區,以形成導電柱231。接著,可移除遮罩層280。因此,可提供其中安裝有電子元件的區。另外,與上述示例性實施例類似,若需要,則可在形成導電柱231之後藉由導電柱231來實行配線部210a及210b等的電性測試。
接著,如圖16中所示,可在配線部210a及210b上安裝包含電極焊墊221的電子元件220,並可藉由在電極焊墊221與電極焊墊214b之間施加導電黏合劑222而將電子元件220結合至配線部。
接下來,如圖17中所示,可形成囊封體230。在此種情形中,如上所述,可使用處於非硬化狀態中的塗有樹脂的銅(RCC)。在形成囊封體230之後,可形成用於電性連接至隨後所安裝的附加電子元件等的傳導結構。為此,可使用以下方法:局部地移除囊封體230以形成暴露出導電柱231的孔H,並接著形成將導電圖案233與導電柱231連接至彼此的導電介層窗232。
接下來,如圖18中所示,可在囊封體230上安置附加或第二電子元件240,且可形成覆蓋附加或第二電子元件240的附加或第二囊封體250。然而,可省略本製程。亦即,可在其中不形成附加電子元件240及附加囊封體250的狀態中實行後續製程。接著,與上述示例性實施例類似,可移除支撐架260,且可移除作為連接至其他導電圖案212a的測試圖案的連接部,以將電性測試配線S電性隔離。接著,與上述示例性實施例類似,可形成外層及連接端子,藉此可獲得封裝結構。
如上所述,根據本發明中的示例性實施例,所述電子元件封裝可具有緊湊的大小,且即使在其中使用多個電子元件的情形中仍可具有高利用率。另外,可在安裝電子元件之前實行電性測試,藉此可顯著提高製造效率。此外,可藉由根據本發明中示例性實施例的製造電子元件封裝的方法來高效地製造上述電子元件封裝。
儘管以上已示出並闡述了示例性實施例,然而對於熟習此項技術者將顯而易見,在不背離由隨附申請專利範圍界定的本發明的範圍的條件下,可作出潤飾及變型。
