1260718 五、發明說明(1) ^ 【發明所屬之技術領域】 本發明涉及到把半導體晶片焊接(b ο n d i n g )到承載 器或襯底上。晶片通常具有鍍有焊料層的背面,以闬於接 觸以.号與承載器. 襯底之間"炙金屬結i ,在工藝' ί通常 稱之為晶片的低熔點焊接(e u t e c t i c b〇n d i n g )。 【先前技術】 半導體晶片或積體電路等形式的半導體器件一般要被 裝進封裝件中。封裝件提供多種重要的功能,例如保護器 件免受機械與化學損傷。同時它也是該器件與下一級封裝 —進行互連的橋梁。晶片貼裝是封裝玉藝涉及到的多個步驟 中的一個,其中晶片被放置並貼附到承載器或襯底上形成 的晶片焊盤上。將器件貼附到晶片焊盤上面有多種方法, •例如使用環氧樹脂和枯性樹脂作為钻結劑將器件枯附到晶 片焊盤上,或者將助熔劑衝壓(s t a m p i n g )到晶片焊盤上 面,吏名後在才斗回ϋ王藝(s〇1 der reflow process ) ^ m 將背面帶有焊料的晶片放置到助熔劑上面。 一種越來越流行的做法是直接將背面鍍上焊料的晶片 固定到加熱的襯底上。當焊料接觸到加熱的襯底的時候就 會熔化,並形成與襯底的結合。這種方法通常被稱為低熔 點晶片焊接,因為晶片上的焊料通常含有低熔點合金成 分。相對於採用純金屬來說,低熔點晶片焊接利用了低熔 點合金的較低熔點特性。當器件與晶片焊盤時,襯底的溫 度應該被升到高於晶片背面焊料的熔點以便焯料能夠立即 熔化。當襯底隨後冷卻下來之後,在晶片背面和襯底上的

第10頁 1260718 五、發明說明〈6) 這個排列的問題是對於一個較長的時間段’在X 1和X 2 點及其以外的區域,加熱塊3 0不僅加熱引線框1 2的金屬部 分1 3,同時也加熱塑膠外殼1 4。由於塑膠材料較低的熱導 牙以及從加隹a 3 0接受到"〜熱量,塑鮮外殼1 4的〉“::变升高 到其無定形溫度(glass temperature ) 以上,並且可奇b 由於熱量產生變形或其他的損壞。最終產品的質量可能因 此受到影響。 圖4所示為現有技術中用於促進晶片1 0貼裝到聚合物 襯底1 6上的熱隧道2 2的側視示意圖,其中聚合物襯底1 6包 >含其上裝有金屬引線框1 8的塑膠條2 0。從其上傳送聚合物 襯底16的熱隧道22上下分別被頂蓋24和加熱台27限制。頂 蓋2 4在晶片貼裝位置有一個窗口 ,用於將背面帶有焊料的 晶片1 0放置到聚合物襯底1 6的金屬引線框1 8上面。 如同圖3中一樣,聚合物襯底1 6從圖的左邊向右邊移 動。隨著它通過含有内嵌加熱單元3 2的加熱塊3 0,其根據 加熱曲線被加熱。從沿熱隧道2 2的加熱塊3 0的排列獲得的 加熱曲線被顯示在圖4中。在由頂蓋2 4的視窗寬度定義的 XI和X2位置之間,金屬引線框1 8的溫度位於Tb以使得低熔 焊接能夠進行。 然而,可以看出金屬引線框1 8的溫度在一段較長的時 間内被保持在T b ’更確切的說’在X 1和X 2之間以及之外。 因此,聚合物襯底1 6的具有較低熱導率的塑膠條2 0可能由 於其吸收的熱量發生變形或者$其他形式的損壞。 圖5所示為根據本發明較佳實施例所述的熱隧道2 2的

應該指出的是,雖然上述描述是關於晶片貼裝位置之 外的以傳統加熱塊形式出現的非感應加熱方法的使用,感 應加熱器件同樣也能在晶片貼裝位置之外被使用,從而可 以合理的調節襯底在加熱管道中移動時的溫度曲線。晶片 貼裝位置感應加熱的使用避免了熱量直接傳遞到承載器或 襯底上的非金屬材料,以便降低非金屬材料到達其無定形 化或熔化溫度的速率。取而代之的是,熱量被間接的從金 屬引線框1 8傳遞到塑膠條2 0。並且,低熔點焊接溫度Tb被 保持了一段較短的時間,其剛剛足以放置晶片和進行晶片 和待焊接金屬表面之間低熔點焊接的發生。由於以上這些 因素,非金屬材料損傷的風險被降低或消除了 ,並且最終 產品的質量可能因此而被提高。 此處描述的本發明在所具體描述的内容基礎上很容易 產生變化、修正和/或補充,可以理解的是所有這些變 化、修正和/或補充都包括在本發明的上述描述的精神和 範圍内。
