Description

用於積體電路裝置之3D積體微電子總成及其製造方法(二) 發明領域
本發明係有關半導體封裝,且更特別有關一其上安裝一半導體裝置之3D中介層。
發明背景
半導體裝置趨勢係在於被封裝在更小封裝體(其保護晶片同時提供晶片外信號連接性)中之更小的積體電路裝置(IC裝置,亦稱為晶片)。近來已經發展並修製將相關晶片堆積在單一封裝體內之3D封裝。3D封裝可導致增高的密度及較小的形狀因數(form factor)、較好的電性效能(因為較短的互連體長度容許具有增高的裝置速度及較低的功率消耗)、較好的異質積造(亦即積造諸如一影像感測器及其處理器等不同的功能層)、及較低的成本。包括先鑽孔(Via-First)、後鑽孔(Via-Last)及中鑽孔(Via-middle)製程等用以形成貫通矽導孔(TSV)之既有3D IC封裝技術係利用先天即複雜且昂貴的半導體微影製程。結果,世上少有公司能負擔每年數十億美元計的CMOS研發費用以求跟上腳步。
另一相關的3D封裝技術係為中介層。一習見的中介層係為一絕緣基材(典型為塑膠或陶瓷),在基材上、中及/或經過基材形成傳導圖案以提供一用於半導體裝置之電性介面。中介層常使用於採用倒裝晶片方法利用銲球生成晶片與中介層之間的電性連接之晶片組裝技術。中介層可提供 相對於半導體裝置上的電性連接圖案或密度具有一經修改、增加、或減小的連接圖案或密度之電性連接。
更晚近來說,隨著貫通矽導孔來臨,已發展出3D矽及玻璃中介層以增大印刷電路板與積體電路之間的間隙,兩者皆就幾何結構及材料而言,以供使用於系統級封裝(SIP)、封裝體疊加(PoP)、倒裝晶片球柵陣列(fc-BGA)或更晚近的扇出晶圓層級封裝。3D中介層係合併晶圓層級技術與優點以及3D繞佈能力(譬如較高解析度及較細微的間距/密度)。
一習見的3D中介層顯示於第1圖。中介層1係包括一矽基材2、貫通矽導孔3,其延伸經過基材且形成基材的一電接觸部、繞佈層4及SMT相容接觸部5、倒裝晶片連接器6(其上安裝一IC晶片7)。製造中介層1的困難係涉及隨著基材2寬度增大而難以製造之導孔3(譬如需要昂貴的半導體濺鍍工具)。並且,會由於中介層與其上安裝有該中介層的PC板之間的不同熱及機械特徵所造成之熱應力,而使得中介層1與下屬印刷電路板之間的SMT接觸部5失效。需要一互補性、合乎成本效益的TSV解決方案以增強3D中介層的效能。
發明概要
本發明係為可解決習見中介層的缺陷之一3D中介層及其製造方法。
中介層係包括一具有相對的第一及第二表面之晶系基材處置器,其中一凹穴係形成進入第一表面,配置於處置 器中之用以界定凹穴的一表面上之一層的絕緣材料,配置於凹穴中之一順應性介電材料,以及複數個電性互連體。各電性互連體係包括一形成經過晶系基材處置器從第二表面延伸至凹穴之第一孔,一形成經過順應性介電材料藉以從第一孔延伸且對準之第二孔,沿著第一孔的一側壁形成之一層的絕緣材料,以及延伸經過第一及第二孔之傳導材料。
形成中介層之方法係包括形成一凹穴於一具有相對的第一及第二表面之晶系基材處置器中,其中凹穴係形成進入晶系基材處置器的第一表面;將複數個第一孔形成經過晶系基材處置器並從第二表面延伸至凹穴;形成一層的絕緣材料於處置器中之用以界定凹穴的一表面上,及於第一孔的側壁上;形成順應性介電材料於凹穴中;將第二孔形成經過順應性介電材料,使得第二孔的各者從第一孔的一者延伸且與第一孔的該一者對準;以及對於從第一孔的一者延伸、且與第一孔的該一者對準之第二孔的各一者,形成係延伸經過該一第一孔及該一第二孔之傳導材料。
將經由檢閱說明書、申請專利範圍及附圖得知本發明的其他目的及特徵構造。

較佳實施例之詳細說明
本發明係為3D中介層,其形成方式如同下文所描述及第2至7圖所顯示。形成製程開始係為如第2圖所示的一晶系基材處置器10。一非限制性範例可包括具有約600μm厚度之晶系基材的一處置器。利用一雷射、一電漿蝕刻製程、一噴砂製程、一機械銑製製程、或任何其他類似方法將一凹穴12形成於處置器中。較佳地,凹穴12藉由光微影術電漿蝕刻形成,其包括形成一層光阻於處置器10上,將光阻層圖案化以曝露處置器10的一選擇部分,且然後進行一電漿蝕刻製程(譬如使用一SF6電漿)以移除處置器10的經曝露部分以形成凹穴12。較佳地,凹穴12延伸不超過晶系基材厚度的3/4,或至少留下約50μm的最小厚度。電漿蝕刻可為異向性、推拔狀、等向性、或其組合。
通孔14隨後被形成經過處置器10的薄化部分,因此從凹穴12延伸至上表面,如第3圖所示。孔14可利用一雷射、一電漿蝕刻製程、電漿與濕蝕刻的一組合、一噴砂製程、或任何類似方法形成。較佳地,通孔14藉由與形成凹穴12類似的方式形成(差異在於孔14一路延伸經過晶系基材處置器10的薄化部分)。電漿矽蝕刻(譬如異向性、推拔狀、等向性、或其組合)係容許具有不同形狀的孔輪廓。較佳地,孔14的輪廓為推拔狀,其中一較小維度位於孔14的凹穴側,且一較大維度位於處置器10的頂表面。較佳地,最小 孔直徑為約10μm,且壁的角度相對於與可供經過其形成孔14之晶系基材表面呈正交的方向位於5°至45°之間,俾使孔在其頂表面上以起在面對凹穴12的表面上具有一更大的橫剖面尺寸。處置器10的全部經曝露表面(或至少是界定凹穴12之表面、孔14的側壁及處置器10的頂表面)係塗覆有一層16的絕緣材料,如第3圖所示(亦即,利用一噴灑製程、一PECVD製程、一電化沉積製程等所施加)。在一較佳的非限制性實施例中,絕緣材料層16可為二氧化矽(SiO2),利用一PECVD製程所施加,具有100埃(Angstroms)的最小厚度。
凹穴12隨後利用一旋塗製程、一噴灑製程、一配送製程、一電化沉積製程、一層疊製程、或任何其他的類似方法充填一順應性介電材料18,如第4圖所示。一順應性介電質係為在三正交方向皆展現順應性、且可容納晶系基材(~2.6ppm/℃)與Cu(~17ppm/℃)互連體之間的熱膨脹係數(CTE)不匹配之一種相對軟材料(譬如銲罩)。順應性介電材料18較佳係為一聚合物,諸如BCB(苯環丁烯)、銲罩、銲阻、FR4、模具化合物、或BT環氧樹脂。通孔20隨後形成經過介電材料18,並對準於孔14。可利用對於較大尺寸孔20的一CO2雷射(譬如約70μm的斑點尺寸)、或對於較小尺寸孔20(譬如小於50μm直徑)的一UV雷射(譬如在355nm波長之約20μm的斑點尺寸)來形成孔20。可使用小於140ns脈衝長度位於10及50kHz之間的雷射脈衝頻率。較佳地,通孔20具有10μm的最小直徑,且相對於垂直方向傾斜不大於15度。
通孔20的側壁隨後被金屬化(亦即塗覆有一金屬化層22)。金屬化製程較佳開始係為用於移除通孔20內部壁上髒污(由鑽過諸如環氧樹脂、聚醯亞胺、氰酸鹽酯樹脂等介電材料所造成)的任何樹脂之去污製程。該製程係涉及使樹脂髒污與γ丁內酯與水的一混合物作接觸以軟化樹脂髒污,接著以一鹼性過錳酸鹽溶液作處理以移除軟化的樹脂,並以一水性酸性中和劑作處理以中和並移除過錳酸鹽殘留物。在去污處理之後,初始傳導金屬化層22係由無電極銅鍍覆形成,接著係為一光微影術回蝕使得金屬化層(在孔20底部)沿著介電質18延伸遠離孔20且(在孔14頂部)沿著絕緣層16遠離孔14,兩者皆為一段短距離(譬如25μm或以上)。藉由來自表面粗度的一錨固效應在經鍍覆介面獲得黏著。所產生的結構顯示於第4圖。
隨後藉由將一層金屬(譬如藉由金屬濺鍍)沉積於絕緣層16(及從孔14延伸之金屬層22的那些部分)上方、及介電材料18(及從孔20延伸之金屬層22的那些部分)上方,而使金屬接觸部形成於孔組合14/20的兩端。隨後進行一可光成像性阻劑層的沉積,接著是一光微影術步驟(亦即經過一罩幕的UV曝光以及選擇性阻劑層移除),接著是被光阻移除所曝露的那些部分之選擇性金屬蝕刻,及光阻移除。所產生的結構顯示於第5圖,其中金屬接觸部24配置於孔14上方並電性接觸於自其延伸的金屬層22,且金屬接觸部26配置於孔20上方並電性接觸於自其延伸的金屬層22。
如第6圖所示,可藉由連同光微影術步驟進行一系列的 交替之絕緣與傳導層形成以生成將電接觸部26繞佈至其在中介層底表面上的所欲最終位置之繞佈層28,而使金屬接觸部26被延伸、扇出、或扇入。這些繞佈層亦將順應性介電材料18包封在凹穴12中。繞佈製程完成時,外金屬層可鍍覆有Ni及Au。金屬接觸部24亦可往上延伸,其中藉由金屬沉積及微影性蝕刻形成額外的金屬層(譬如銅)。BGA互連體30及32隨後分別利用一銲料合金的一絲網印刷製程、或藉由一球置放製程、或藉由一鍍覆製程而形成於金屬接觸部24及26上。BGA(球柵陣列)互連體係為用於與對偶導體產生物理及電性接觸之圓弧形導體,通常藉由將金屬球銲接或部份地融化在結合墊上所形成。所產生的結構係為第7圖所示的中介層總成36。
一IC晶片38可隨後被積造(亦即機械性附接或安裝)至中介層36,如第8圖所示,其中BGA互連體30係與IC晶片38的結合墊40接觸且產生電性連接。可利用習見的揀放或晶粒附接設備進行積造。較佳地,這係在一加熱環境中進行,故BGA互連體30係結合於金屬接觸部24及結合墊40(且在其間產生一穩固電性連接)。藉由第8圖所示之所產生的結構,IC晶片38的各結合墊40經由BGA互連體30、金屬接觸部24、延伸經過孔14/20之金屬層22、及金屬接觸部26(延伸經過繞佈層28)而在中介層36底部上被電性耦合至BGA互連體32的至少一者。
上述及圖示的中介層36及其製造方法具有數項優點。第一,孔14/20及其中的金屬層22係形成電性互連體,電性 互連體將信號轉移經過中介層、且將BGA互連體30電性耦合至BGA互連體32。第二,可避免形成經過晶系處置器的長孔,而是形成經過處置器10的一薄化部分之較短的孔14。相較於需要昂貴矽蝕刻設備及處理之經過晶系矽形成較長的孔而言,經過介電質18形成較長的孔20係更容易且需要更便宜的設備及處理。第三,絕緣層16及介電質18的組合提供優異的電性絕緣。第四,因為相較於若中介層主要為貫穿其整體厚度之晶系矽的情形,介電材料18的熱及機械特徵更良好地匹配於將安裝有中介層36之PCB的熱及機械特徵,機械應力係降低。第五,介電材料18額外地提供優異的機械性絕緣。
