Description

封裝結構及其製法
本發明係有關於一種封裝結構及其製法,尤指一種具有線路層的封裝結構及其製法。
現行之覆晶技術因具有縮小晶片封裝面積及縮短訊號傳輸路徑等優點,目前已經廣泛應用於晶片封裝領域,例如:晶片尺寸構裝(Chip Scale Package,CSP)、晶片直接貼附封裝(Direct Chip Attached,DCA)以及多晶片模組封裝(Multi-Chip Module,MCM)等型態的封裝模組,其均可利用覆晶技術而達到封裝的目的。
於覆晶封裝製程中,因晶片與封裝基板之熱膨脹係數的差異甚大,故晶片外圍的凸塊無法與封裝基板上對應的接點形成良好的接合,使得凸塊容易自封裝基板上剝離。另一方面,隨著積體電路之積集度的增加,因晶片與封裝基板之間的熱膨脹係數不匹配(mismatch),其所產生的熱應力(thermal stress)與翹曲(warpage)的現象也日漸嚴重,其結果將導致晶片與封裝基板之間的電性連接之可靠度(reliability)下降,並造成信賴性測試的失敗。
為了解決上述問題,遂發展出以半導體基材作為中介結構的製程,其係於一封裝基板與一半導體晶片之間增設一矽中介板(silicon interposer),因為該矽中介板與該半導體晶片的材質接近,故可有效避免熱膨脹係數不匹配所產生的問題。
請參閱第1圖,係習知具矽中介板之堆疊封裝結構之剖視圖。如圖所示,習知之封裝結構除了能避免前述問題外,相較於直接將半導體晶片接置於封裝基板之情況,習知之封裝結構亦可使封裝結構的版面面積更加縮小。
舉例來說,一般封裝基板最小之線寬/線距只可做到12/12微米,而當半導體晶片的輸入輸出(I/O)數增加時,由於線寬/線距已無法再縮小,故須加大封裝基板的面積以提高佈線數量,以便於接置高輸入輸出(I/O)數之半導體晶片;相對地,由於第1圖之封裝結構係將半導體晶片11接置於一具有矽貫孔(through silicon via,TSV)121的矽中介板12上,以該矽中介板12做為一轉接板,進而將半導體晶片11電性連接至封裝基板13上,而矽中介板12可利用半導體製程做出3/3微米或以下之線寬/線距,故當半導體晶片11的輸入輸出(I/O)數增加時,該矽中介板12的面積已足夠連接高輸入輸出(I/O)數之半導體晶片11。此外,因為該矽中介板12具有細線寬/線距之特性,其電性傳輸距離較短,所以連接於該矽中介板12之半導體晶片11的電性傳輸速度(效率)亦較將半導體晶片直接接置封裝基板之速度(效率)來得快。
惟,由於習知係使用矽中介板12的矽貫孔121來電性連接上下兩側的半導體晶片11與封裝基板13,但製作矽貫孔121會使得整體封裝成本提高;此外,最終封裝結構也會因為多了矽中介板12而增加不少厚度。
因此,如何避免上述習知技術中之種種問題,實為目前業界所急需解決的課題。
有鑒於上述習知技術之缺失,本發明提供一種封裝結構,係包括:具有貫穿之開口的框體;設於該框體的開口中的半導體晶片,係具有外露於該開口之相對的作用面與非作用面;形成於該開口中之介電層,以接觸並固定該半導體晶片,且該介電層與該作用面側之框體表面齊平;以及形成於該作用面側之介電層上的線路層,以電性連接該作用面。
本發明復提供一種封裝結構,係包括:框體,係具有貫穿之開口;半導體晶片,係設於該框體的開口中,且具有外露於該開口之相對的作用面與非作用面;介電層,係形成於該開口中,以接觸並固定該半導體晶片;線路層,係形成於該作用面側之介電層上,以電性連接該作用面;以及承載板,係設於該框體、介電層和半導體晶片之非作用面上,且該框體和承載板係非一體成形。
本發明復提供一種封裝結構之製法,係包括:提供一具有相對之第一表面與第二表面的承載板,該承載板之第一表面上形成有具有外露該第一表面之開口的框體,該框 體和承載板係非一體成形,該開口中的第一表面上設置有具相對之作用面與非作用面的半導體晶片,該半導體晶片係以該非作用面接合該第一表面,且該開口中填有介電層,以接觸並固定該半導體晶片;於該介電層上形成線路層,以電性連接該作用面;以及移除該承載板,以外露該半導體晶片之非作用面。
於一具體實施例中,提供該承載板與框體及設置該半導體晶片之步驟係包括:於該承載板上設置該半導體晶片;於該承載板上接置一具有凹部的蓋板,該凹部面對該承載板,令該半導體晶片對應容置於該凹部中;移除該蓋板之部分厚度,以外露該半導體晶片及該蓋板所留下之該框體;以及於該框體之開口中形成具有外露至少部分之該作用面的介電層。
於另一具體實施例中,形成該框體及該介電層之步驟係包括:提供一其上設有該半導體晶片及一具有凹部的蓋板的該承載板,該凹部面對該承載板,使該半導體晶片對應容置於該凹部底面,並令該蓋板懸空在該承載板上;於該凹部中及蓋板和承載板之間形成介電層,以接觸並固定該半導體晶片;以及移除該蓋板之部分厚度,以外露該半導體晶片及該蓋板所留下之該框體。
由上可知,本發明係以較便宜的線路層取代習知之中介板,且亦省去習知半導體晶片與中介板之間的銲球,因此能有效減少封裝結構的成本與厚度。

上述實施例係用以例示性說明本發明之原理及其功效,而非用於限制本發明。任何熟習此項技藝之人士均可在不違背本發明之精神及範疇下,對上述實施例進行修改。因此本發明之權利保護範圍,應如後述之申請專利範圍所列。
