Description
本發明係有關一種半導體封裝件,尤指一種提高製作良率之半導體封裝件及其製法。
隨著電子產業的蓬勃發展,電子產品也逐漸邁向多功能、高性能的趨勢。目前應用於晶片封裝領域之技術,例如晶片尺寸構裝(Chip Scale Package,CSP)、晶片直接貼附封裝(Direct Chip Attached,DCA)或多晶片模組封裝(Multi-Chip Module,MCM)等覆晶型態的封裝模組、或將晶片立體堆疊化整合為三維積體電路(3D IC)晶片堆疊技術等。
第1圖係為習知3D晶片堆疊之半導體封裝件之製法之剖面示意圖。如第1圖所示,提供一矽中介板(Through Silicon interposer,TSI)1,該矽中介板1具有相對之置晶側10a與轉接側10b、及連通該置晶側10a與轉接側10b之複數導電矽穿孔(Through-silicon via,TSV)100,且該轉接側10b上具有一線路重佈結構(Redistribution layer,RDL)101。將間距較小之半導體晶片9之電極墊90係藉由複數銲錫凸塊102電性結合至該置晶側10a上,再以底
膠92包覆該些銲錫凸塊102,且形成封裝膠體8於該矽中介板1上,以覆蓋該半導體晶片9。於該線路重佈結構101上藉由複數如凸塊之導電元件103電性結合間距較大之封裝基板7之銲墊70,並以底膠72包覆該些導電元件103。
第1A至1F圖係為習知矽中介板之製法之示意圖。
如第1A圖所示,提供一已完成佈線製程而尚未切割之晶圓10,其係由複數如第1F圖所示之矽中介板1所構成(其詳細內部結構可參考第1F圖),且該晶圓10之置晶側10a上覆蓋有一支撐件11之保護層110,使該些銲錫凸塊102埋設於該保護層110中。
如第1B圖所示,將該晶圓10以其轉接側10b結合至一第一承載件12之第一膠膜120上,使該些導電元件103埋設於該第一膠膜120中。
如第1C圖所示,移除該支撐件11及其保護層110,以外露該置晶側10a。
如第1C-1圖所示,於該第一膠膜120上進行預切割製程,以產生複數V形預切割道121於該第一膠膜120上。
如第1C-2圖所示,以一機械手臂5固定(如真空吸附)該晶圓10之置晶側10a。
如第1C-3圖所示,翻轉倒置整體結構,再移除該機械手臂5。接著,利用預切割道121進行定位,使整體結構以該置晶側10a固定於定位板4上,再固化該第一膠膜120。
如第1C-4圖所示,以另一機械手臂5’固定(如真空
吸附)該第一承載件12。
如第1C-5圖所示,移除該定位板4,再將第二承載件13之第二膠膜130結合至該晶圓10之置晶側10a,使該些銲錫凸塊102埋設於該第二膠膜130中。
如第1D圖所示,移除該另一機械手臂5’與第一承載件12,且藉由該預切割道121移除該第一膠膜120。
如第1E圖所示,進行切單作業,以於該晶圓10之轉接側10b上藉由雷射機6進行隱形切割(Stealth Dicing,簡稱SD)製程。
如第1F圖所示,以機械手臂(圖略)取出各該矽中介板1。
目前製作該矽中介板1,於晶圓10進行雷射切單時,因該置晶側10a具有特殊佈線而令雷射無法穿透,故於移除該支撐件11及其保護層110後,需先經過重置(remount)作業,即將第二承載件13之第二膠膜130結合至該晶圓10之置晶側10a,使該轉接側10b朝上,再進行切割。
惟,前述習知矽中介板1之製法中,由於先將該晶圓10以其轉接側10b結合至一第一承載件12之第一膠膜120上,再移除該支撐件11及其保護層110,故於進行切單製程前,需進行重置作業,因而第1C圖至第1D圖的過程極為複雜,即需經過許多步驟(如第1C-1至1C-5圖所示),導致於第1C-2圖所示之製程、第1C-3圖之翻轉倒置及定位步驟將產生破損(crack)(因晶圓10之厚度僅100um)
或掉落之風險、或於第1D圖之移除該第一膠膜120時,將產生該第二膠膜130脫落(peeling)之風險,以致於製造良率下降,因而增加產品成本。
再者,第1C圖至第1D圖之步驟繁多,將降低產量(throughput),而難以降低產品成本。
因此,如何克服上述習知技術的種種問題,實已成目前亟欲解決的課題。
鑑於上述習知技術之種種缺失,本發明係提供一種中介基板之製法,係包括:提供一基板本體,該基板本體具有相對之置晶側與轉接側、及連通該置晶側與轉接側之導電穿孔,且該置晶側上覆蓋有一保護層;於該基板本體之轉接側上進行切單製程;將該基板本體以其轉接側結合至一承載件上;移除該保護層;以及移除該承載件,以取得複數該中介基板。
前述之製法中,該基板本體係為半導體板體。
前述之製法中,該基板本體係為晶圓型式。
前述之製法中,該中介基板係為晶片型式。
前述之製法中,該中介基板之轉接側係用以電性結合封裝基板,該置晶側係用以電性結合晶片。
另外,前述之製法中,該切單製程係為隱形切割製程。
由上可知,本發明之中介基板之製法,藉由先進行切單製程,再移除該保護層,以省略習知重置作業,故能避免習知技術之破裂、掉落或脫落之風險,以提高產品之良
率。
再者,本發明省略習知重置作業,故能節省製程時間及購買機台之成本,因而能提高製程效率。
又,本發明省略習知重置作業,因而能減少該基板本體於生產線上傳送時所造成之產品損壞問題。
另外,本發明省略習知重置作業,能避免該基板本體因該第二膠膜脫落而造成產品損壞之問題。

如第2D圖所示,移除該支撐件21及其保護層210,以外露出該置晶側20a與銲錫凸塊202。
如第2E圖所示,移除該承載件22及其膠膜220,且由於已進行切單作業,故能取得複數該中介基板2。
於本實施例中,該中介基板2係為晶片型式,且作為矽中介板,使該轉接側20b用以電性結合封裝基板(如第1圖所示之封裝基板7),該置晶側20a用以電性結合晶片(如第1圖所示之半導體晶片9)。
綜上所述,本發明之中介基板2之製法,係藉由將該基板本體20先進行切單作業,再移除該支撐件21及其保護層210,故能省略習知重置作業(即第1C-5圖所示之第二承載件13之第二膠膜130結合至該晶圓10之置晶側10a),以節省成本與時間,且能省略習知技術需經多個製程步驟所造成之風險。
再者,本發明之中介基板2之製法省略習知重置作業,故能節省製程時間,並能避免習知技術降低製程良率之問題,故能產量,以降低產品成本。
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。
20‧‧‧基板本體
20b‧‧‧轉接側
21‧‧‧支撐件
210‧‧‧保護層
6‧‧‧雷射機
