Description
本揭露係有關一種封裝基板及其製法,尤指一種嵌埋有中介層之封裝基板及其製法。
隨著電子產業的蓬勃發展,電子產品在型態上逐漸趨於輕薄短小,在功能上則逐漸邁入高性能、多功能、與高速度化的研發方向,致使半導體晶片之佈線密度愈來愈高,而以奈米尺寸作單位。因此,目前所用以承載晶片之封裝基板(如覆晶式載板)已無法配合高線路密度之半導體晶片,因而業界遂發展出一種3D-SiP(System-in-package)封裝製程。
請參閱第1圖,係一種習知3D-SiP封裝件1之剖視圖,如第1圖所示,其係於一封裝基板1’與一半導體晶片15之間增設一矽中介層(Silicon interposer)12,該矽中介層12係採用矽穿孔(Through-silicon via,TSV)技術而具有複數貫穿且用以電性連接之導電穿孔121,且於該矽中介層12上形成一線路重佈結構(Redistribution layer,RDL)122,令該些導電穿孔121之一端電性結合間距較大之封裝基板1’,而該線路重佈結構122則電性結合間距較小之半導體晶片15,使該封裝基板1’可結合具有高佈線密度之半導體晶片15,之後再將封裝件設置於一電路板9上。故藉由該矽中介層12,不僅可解決缺乏可配合之載板的問題,且不會改變IC產業原本之供應鏈(supply
chain)及基礎設備(infrastructure),進而使最終的半導體封裝件具有高整合度、高效率、低耗電、小體積與低成本的優勢。
惟,習知3D-SiP封裝件1中,該封裝基板1’僅能堆疊例如半導體晶片15之主動元件,而無法同時設置該些被動元件14,亦即須將該些被動元件14設置於該電路板9上,故該半導體晶片15與該被動元件14之間的導電路徑過長,因而該半導體晶片15之電壓容易出現不穩定現象,致使最終電子產品的電性效能無法大幅提升。
再者,因該些被動元件14設於該電路板9上,故該些被動元件14不僅佔用該電路板9之佈設面積,且減少該電路板9之佈線空間,因而難以縮小產品之體積,且將減少產品之功能。
因此,如何克服習知技術中之種種問題,實已成目前亟欲解決的課題。
本揭露之一實施例提出一種封裝基板,係整合有中介層與被動元件。該封裝基板可包括:基板本體,係具有線路、相對之第一表面和第二表面,該第一表面係具有複數電性接觸墊;絕緣保護層,係形成於該基板本體的第一表面上;中介層,係埋設於該絕緣保護層中並電性連接該基板本體,且該中介層係具有複數貫穿的導電穿孔及外露於該絕緣保護層之線路重佈結構;以及至少一被動元件,係設於該基板本體的第一表面之上。
因此,相較於習知技術,當半導體晶片設於該中介層之線路重佈結構上時,可縮短該半導體晶片與被動元件之間的距離,即主動元件(如該半導體晶片)與被動元件之間的電性連接路徑縮短,使主動元件的腳位電壓較為穩定,因而能提升最終產品的電性效能。
再者,因該些被動元件無需設於電路板上,因而不會佔用電路板之佈設面積,故可增加該電路板之佈線空間,不僅可縮小產品之體積,且可增加產品之功能。
以下藉由特定的具體實施例說明本揭露之實施方式,熟悉此技藝之人士可由本說明書所揭示之內容輕易地瞭解本揭露之其他優點及功效。
須知,本說明書所附圖式所繪示之結構、比例、大小等,均僅用以配合說明書所揭示之內容,以供熟悉此技藝之人士之瞭解與閱讀,並非用以限定本揭露可實施之限定條件,故不具技術上之實質意義,任何結構之修飾、比例關係之改變或大小之調整,在不影響本揭露所能產生之功效及所能達成之目的下,均應仍落在本揭露所揭示之技術內容得能涵蓋之範圍內。同時,本說明書中所引用之如「上」、「頂」、「底」、「四周」、「上方」及「一」等之用語,亦僅為便於敘述之明瞭,而非用以限定本揭露可實施之範圍,其相對關係之改變或調整,在無實質變更技術內容下,當亦視為本揭露可實施之範疇。
本文中提及之“導電穿孔”係指形成於基材,例如本文
之中介層中的導電元件,以本文圖式為例,其外型如柱狀體。
請參閱第2圖,係本揭露之封裝基板2的第一實施例的剖視圖。
如第2圖所示,係先提供一具有線路200、頂表面(可視為第一表面)20a和底表面(可視為第二表面)20b的基板本體20,例如為多層內連線基板(multi-layer interconnect base plate),該頂表面20a係具有複數電性接觸墊21a,又該頂表面20a上係設有一中介層22與一絕緣保護層23,該中介層22嵌埋於該絕緣保護層23中並外露於該絕緣保護層23表面。接著,於該中介層22上設置複數被動元件24。
於本實施例中,該中介層22例如為矽中介層(Silicon interposer)且具有複數貫穿的導電穿孔221及外露於該絕緣保護層23之線路重佈結構(redistribution layer,RDL)222,該些導電穿孔221之底端係連接該電性接觸墊21a以電性連接該線路200,且該被動元件24係設於該線路重佈結構222上以電性連接該中介層22。
再者,藉由該被動元件24設於該線路重佈結構222上,以當如半導體晶片之主動元件(圖略)設於該線路重佈結構222上時,使該主動元件得以最靠近該被動元件24之方式組裝,而可大幅縮減該主動元件與該被動元件24之間的距離。
亦即,訊號透過該線路重佈結構222與被動元件24串接後,並透過該些導電穿孔221傳輸到該基板本體20,故該主動元件與被動元件24之間的電性連接路徑最短,因而該主動元件的腳位電壓最為穩定。
請參閱第3A至3C圖,係本揭露之封裝基板3的第二實施例之製法的剖視圖。本實施例與第一實施例之差異在於該被動元件24之位置及電性連接方式,其他相關結構大致相同,故不再贅述。
如第3A圖所示,藉由定深式機械鑽孔方式或雷射鑽孔方式,於該絕緣保護層23上形成對應外露部分電性接觸墊21a的複數開孔230。
如第3B圖所示,藉由電鍍、印刷、塞孔或噴塗之方式於該些開孔230中形成如柱體之導電元件231。
於本實施例中,該導電元件231之材質係為導電膠或電鍍金屬,如銅膏或銀膠。
如第3C圖所示,於該導電元件231上設置該被動元件24,該些被動元件24係藉由該些導電元件231電性連接該電性接觸墊21a。
於本實施例中,藉由該被動元件24設於該絕緣保護層23上,使該主動元件(圖略)得以較大尺寸設於該線路重佈結構222上,以增加該主動元件之佈線空間,而可提升該主動元件之功能。再者,當該主動元件設於該線路重佈結構222上時,相較於習知技術,本揭露能大幅縮減該
主動元件與該被動元件24之間的電性連接路徑,而能使該主動元件的腳位電壓更為穩定。
請參閱第4圖,係本揭露之封裝基板4的第三實施例的剖視圖。本實施例與第二實施例之差異在於該被動元件24之位置及電性連接方式,其他相關結構大致相同,故不再贅述。
如第4圖所示,藉由定深式機械鑽孔方式或雷射鑽孔方式,於該絕緣保護層23上形成對應外露該些電性接觸墊21a的複數開口232,再利用點膠等相關技術,將該被動元件24焊接於該開口232中的電性接觸墊21a上,令該被動元件24接觸並電性連接該電性接觸墊21a。
於本實施例中,藉由該被動元件24嵌埋於該絕緣保護層23中,可降低該封裝基板4之高度,以利於達到產品薄化之需求。
再者,當該主動元件設於該線路重佈結構222上時,相較於習知技術,本揭露能大幅縮減該主動元件與該被動元件24之間的電性連接路徑,而能使該主動元件的腳位電壓更為穩定。
要補充說明的是,本揭露之封裝基板2,3,4中,該中介層22之線路重佈結構222上係用以接置至少一如半導體晶片之主動元件(圖略),且之後再進行封裝製程,以構成一半導體封裝件,惟此可依據本說明書而能瞭解者,故不在此加以贅述。
再者,於製作該基板本體20時,可將至少一被動元件24’嵌埋於該基板本體20中且電性連接該線路200,如第5圖所示之封裝基板4’。
又,本揭露之基板本體20之底表面20b亦可具有電性接觸墊21b,以供電性連接至其他電子裝置,如:電路板或封裝結構。
另外,所述之各實施例係以無核心(coreless)之基板本體20作為例示說明,但具有核心層之基板本體同樣也可以應用在本揭露之封裝基板中,而且包含在本揭露的申請專利範圍中。
綜上所述,本揭露之封裝基板2,3,4中,係整合有中介層22與被動元件24,故當主動元件設於該中介層22上時,可使該主動元件與該被動元件24之間的距離大幅縮減,即該主動元件與該被動元件24之間的電性連接路徑縮短,因而能使該主動元件的腳位電壓更為穩定,以有效提升最終電子產品的電性效能。
再者,因該些被動元件24無需設於電路板(圖略)上,因而不會佔用電路板之佈設面積,故可增加該電路板之佈線空間,不僅可縮小產品之體積,且可增加產品之功能。
上述實施例係用以例示性說明本揭露之原理及其功效,而非用於限制本揭露。任何熟習此項技藝之人士均可在不違背本揭露之精神及範疇下,對上述實施例進行修改。因此本揭露之權利保護範圍,應如後述之申請專利範
