Abstract

一種電子封裝件係包括:具有導電柱之第一線路結構、設於該第一線路結構上且包含第一電子元件、第二電子元件與導電體的堆疊結構、包覆該堆疊結構與該導電柱之包覆層、以及形成於該包覆層上之第二線路結構。藉由該堆疊結構之設計,以整合多種晶片於單一封裝件中,且能縮小該電子封裝件之尺寸。本發明復提供該電子封裝件之製法。

Description

電子封裝件及其製法
本發明係有關一種封裝技術,尤指一種半導體封裝件及其製法。
隨著半導體封裝技術的演進,半導體裝置(Semiconductor device)已開發出不同的封裝型態,而為提升電性功能及節省封裝空間,遂開發出不同的立體封裝技術,例如,扇出式封裝堆疊(Fan Out Package on package,簡稱FO PoP)等,以配合各種晶片上大幅增加之輸入/出埠數量,進而將不同功能之積體電路整合於單一封裝結構,此種封裝方式能發揮系統封裝(SiP)異質整合特性,可將不同功用之電子元件,例如:記憶體、中央處理器、繪圖處理器、影像應用處理器等,藉由堆疊設計達到系統的整合,適合應用於輕薄型各種電子產品。
第1圖係為習知用於PoP之半導體封裝件1的剖面示意圖。如第1圖所示,該半導體封裝件1係包括一具有至少一線路層101之封裝基板10,且以覆晶方式結合一半導體元件11於該線路層101上。
具體地,該半導體元件11具有相對之作用面11a與非作用面11b,該作用面11a具有複數電極墊110,以藉由複數如銲錫凸塊12電性連接該電極墊110與該線路層101,並形成底膠13於該半導體元件11與該線路層101之間,以包覆該些銲錫凸塊12。
再者,該半導體元件11形成有一封裝膠體15於該封裝基板10上,以包覆該底膠13及該半導體元件11,且形成複數導電通孔14於該封裝膠體15中,以令該導電通孔14之端面外露於該封裝膠體15,俾供後續藉由銲球(圖略)結合一如中介板或封裝基板等之電子裝置(圖略)。
然而,習知半導體封裝件1中,係以該導電通孔14之外露端面作為外接點,故當該外接點之數量增加時,該導電通孔14之間的間距需縮小,此時各該導電通孔14之端面上之銲球之間容易發生橋接(bridge)。
再者,若習知半導體封裝件1需要更多功能時,該封裝基板10上需以並排(side by side)方式設置更多種類之半導體元件11,此時需增加該封裝基板10之設置面積,因而導致該半導體封裝件1的尺寸增大。
因此,如何克服習知技術之種種缺點,實為目前各界亟欲解決之技術問題。
鑒於上述習知技術之缺失,本發明提供一種電子封裝件,係包括:第一線路結構,係具有相對之第一側與第二側,且該第一側上形成有至少一電性連接該第一線路結構 之導電柱;堆疊結構,係設於該第一線路結構之第一側上,其中,該堆疊結構包含有第一電子元件、及結合並電性連接至該第一電子元件之第二電子元件與至少一導電體;包覆層,係形成於該第一線路結構之第一側上,以令該包覆層包覆該堆疊結構與該導電柱,且令該導電柱之端面外露於該包覆層;以及第二線路結構,係形成於該包覆層上且電性連接該導電柱。
本發明復提供一種電子封裝件之製法,係包括:提供一堆疊結構與一第一線路結構,其中,該堆疊結構包含有第一電子元件、及結合並電性連接至該第一電子元件之第二電子元件與至少一導電體,而該第一線路結構具有相對之第一側與第二側,且該第一側上形成有至少一電性連接該第一線路結構之導電柱;將該堆疊結構設於該第一線路結構之第一側上;形成包覆層於該第一線路結構之第一側上,以令該包覆層包覆該堆疊結構與該導電柱,且令該導電柱之端面外露於該包覆層;以及形成第二線路結構於該包覆層上,且令該第二線路結構電性連接該導電柱。
前述之電子封裝件及其製法中,該堆疊結構以其第一電子元件設於該第一線路結構之第一側上。例如,該導電體之部分表面外露於該包覆層,使該第二線路結構電性連接該導電體;或者,該第二電子元件之部分表面外露於該包覆層,使該第二線路結構接觸該第二電子元件。
前述之電子封裝件及其製法中,該堆疊結構以其導電體設於該第一線路結構之第一側上,且該導電體電性連接 該第一線路結構。例如,該第一電子元件包覆於該包覆層中;或者,該第一線路結構之第一側上復形成有至少一導電凸塊,以令該導電體結合至該導電凸塊上。
前述之電子封裝件及其製法中,該導電柱之表面係形成有表面處理層。
前述之電子封裝件及其製法中,復包括形成複數導電元件於該第一線路結構之第二側上。
前述之電子封裝件及其製法中,復包括形成複數導電元件於該第二線路結構上。
由上可知,本發明之電子封裝件及其製法,主要藉由該堆疊結構之設計,以利於整合多種晶片於單一封裝件中,且能縮小該電子封裝件之尺寸。
再者,藉由在該堆疊結構之上、下方形成第一與第二線路結構,而無需使用傳統的封裝基板,故可減少該電子封裝件之厚度,並降低生產成本。
另外,藉由該第一與第二線路結構之接觸墊(即該第一與第二線路重佈層之外露表面)作為外接點,可利於控制各該接觸墊之間的距離,以符合細間距的需求,且能避免各該導電元件之間發生橋接。

又,該整平製程係藉由研磨方式,移除該導電柱24之部分材質與該包覆層25之部分材質(必要時,移除該導電體22之部分材質,如第2D’圖所示)。
如第2E圖所示,接續第2D圖之製程,形成一第二線路結構26於該包覆層25上,且該第二線路結構26電性連接該些導電柱24與該些導電體22。

再者,該堆疊結構2a之上、下側均形成有線路結構(即該第一與第二線路結構23,26),因而無需使用習知封裝基板,故可減少該電子封裝件2,2’之厚度,並降低生產成本(即免用習知封裝基板)。
另外,藉由該第一與第二線路結構23,26之接觸墊(即外露於該第一絕緣保護層28與第二絕緣層260’之第一與第二線路重佈層231,261’)作為外接點,可利於控制各該接觸墊之間的距離,以符合細間距的需求,且能避免各該第一導電元件27a之間或各該第二導電元件27b之間發生橋接。

再者,藉由在該堆疊結構2a之上、下方形成線路結構(即該第一與第二線路結構33,36),而無需使用傳統的封 裝基板,故可減少該電子封裝件3,3’之厚度,並降低生產成本。
另外,藉由該第一與第二線路結構33,36之接觸墊(即該第一與第二線路重佈層331,361之外露表面)作為外接點,可利於控制各該接觸墊之間的距離,以符合細間距(fine pitch)的需求,且能避免各該第一導電元件27a之間或各該第二導電元件27b之間發生橋接。
