L· U 10 發明背景 第1A至1C圖概略地顯示一習知引線框及一使用該引 線框之半導體裝置的構造。 第1A圖顯示一帶狀引線框1〇之一部份的平面構造。此 一引線框10之框架結構係由一外框部分11以及以矩陣型態 15配置於該外框部分11内部之内框部分12(亦稱為“分段條狀 物”)構成的。該外框部分11設有導孔13,該導孔在轉移該 引線框10時與一轉移機制齒合。一用以安裝半導體元件(晶 片)之四角形晶粒座部分14被設置於該框部分11、12所界定 之各個開口的中央。此一晶粒座部分14由四支從對應框部 20分11和12之四個角落延伸出來的支撐條15支撐。複數條光 束狀引線16以一梳子型態從各該框部分u、12朝該晶粒座 部分14延伸。各該引線16包括一内引線部分16a(第1]5圖), 該内引線部分被電性連接至-待安裝之晶片的電極端子, 以及-外引線部分(外部連接端子)i6b,該外引線部分被電 5 接至一 6壯 中誃引纟文裝板如主機板之架線。虛線CL代表封裝製程 飨a、泉框1〇最後被分割成封裝(半導體裝置)時的分段 、味。雖然汐右一 皆i \ W又頜不於第1A圖中,整個該分段條狀物(内框12) 为割成封裝時被移除。 第1β圖顯示一具有一QFN封裝結構並以該引線框1〇製 “ 冷體叙置20的橫斷面結構。在該半導體裝置20中, ^閱數字21代表一設置於該晶粒座部分14上之半導體元 多閱數子22代表銲線,該銲線將該半導體元件21之各 该電極端子連接至對應之該引線16的該内引線部分i6a;而 芩閱數字23則代表用以保護該半導體元件21、該銲線22以 及其他類似物之密封樹脂。做為該引線16之外部連接端子 的該外引線部分16b被暴露於該半導體裝置20之安裝側,如 弟1B圖所示。 製造該半導體裝置20(QFN封裝)之基本步驟包括:將該 半導體元件21設置於該引線框10之該晶粒座部分14上(黏 晶);以該銲線22將該半導體元件21之各該電極端子電性連 接至該引線框10之對應引線16(打線);以該密封樹脂23黏合 該半導體元件21、該銲線22以及其他類似物(製模);以及以 一切割器或諸如此類將該引線框10分割成封裝(該半導體 裝置20)(切割)。 在執行打線時,如第1C圖所概略顯示者,該半導體元 件21之該電極端子21a以一對一型態利用該銲線22被連接 至對應之該引線16。 根據上述習知引線框(第1A至1C圖)之構造,做為外部 連接端子之該引線16以一梳子型態從該框部分11、12朝該 晶粒座部分14延伸。因此,進一步增加端子數目時,有必 要縮小各該引線之寬度以及各該引線之間的間隔,或者在 保持各該引線等之尺寸下擴大該引線框之尺寸。 然而,各該引線之寬度的壓縮工程在技術面(引線框之 圖案製作所涉及的蝕刻、沖壓等)有其困難度。另一方面, 增加引線框之尺寸的做法會f來材料成本增加之缺點。換 言之,對於習知引線框來說,其光束狀引線(外部連接端子) 以一梳子型態從該框部分朝該晶粒座部分延伸之做法存在 一個問題,亦即,增加端子數目之需求不一定可以被滿足。 本申明案之申凊人已針對此問題提出一解決方案(曰 本專利申請案第2001-262876號,於2003年3月14日早期公 開(曰本早期公開專利第2003-78094號))。此一申請案之說 明書與圖示敘述一種引線框,其包括複數個似陸塊之外部 連接端子,該外部連接端子以點陣型態設置於一介於該框 部分和該晶粒座部分之間之區域,以取代習知的光束狀引 線。相較於具有以梳子型態延伸之光束狀引線(外部連接端 子)的習知引線框,該引線框之端子數目是可以增加的。 該引線框和習知技藝一樣,具有該晶粒座部分。該晶 粒座部分之尺寸(被該引線框所佔據之區域)依待安裝之半 V體元件(晶片)的尺寸決定且維持不變。換言之,一個引線 框對應一種晶片尺寸。因此,它具有一項缺點,亦即,需 要針對每一種待安裝之晶片種類製造一個供其專用的引線 框,是故,此一做法有改善空間。 C發明内容3 發明概要 本發明的目的之一是要提供一種引線框以及製造該引 線框之方法,其中該引線框可以分別應付各種待安裝之+ 導體元件(晶片)尺寸。此外,該引線框允許複數個晶片同時 安裝於一單一封裝(半導體裝置)中,並促成端子數目之增 加。 為達成上述目的,本發明之一態樣提供一引線框,包 括:一框部分;以及複數個似陸塊之傳導部分,該傳導部 份以點陣型態設置於一被該框部分包圍之區域内,其中該 框部分和該複數個似陸塊之傳導部分由一黏合膠帶支樓。 根據此一態樣之引線框的構造,由於該複數個似陸塊 之傳導部分係以點陣型態設置於一被該框部分包圍之區域 内’部分該複數個似陸塊之傳導部分可以依據待安裝之半 &體元件(晶片)的尺寸,充作該晶粒座部分之代替品。換言 之’與習知晶粒座部分之尺寸依晶片尺寸決定且維持不變 的做去相反地,該複數個似陸塊之傳導部分係以點陣型態 5又置’且該似陸塊之傳導部分的需求數目可以用來取代該 曰曰粒座部分。因此,可以以單一引線框來處理各種尺寸的 晶片,不管其個別尺寸為何。 再者,由於該引線框可以安裝任意尺寸之晶片,本發 月了以使複數個晶片同時安裝於一單一封裝(半導體裝置) 此外,由於做為外部連接端子之該複數個似陸塊之傳 200414473 導部分(其中若干部分被做為該晶粒座部分之代替品)係以 點陣型態設置於一被該框部分包圍之區域内,相較於具有 以梳子型態從該框部分朝該晶粒座部分延伸(晶片完成但 端子增加)之光束狀引線(對應於該外部連接端子)的習知引 5 線框,該端子之數目是可以增加的。 另外,本發明在另一態樣中提供一製造引線框之方 法,包括下列步驟:以蝕刻或沖壓一金屬板來形成一底座, 該底座包括一框部分以及複數條引線,該複數條引線以互 相垂直之方式被設置於一由該框部分包圍並連接至該框部 10 分之區域内;以半蝕刻之方式,在該底座之一表面上除了 該引線互相交叉之部分和該框部分以外的部分形成凹面部 分;在該底座表面上形成該凹面部分之處加上黏合膠帶; 以及將該引線之形成該凹面部分的部分切割下來。 根據此一態樣之引線框的製造方法,該引線之形成該 15 凹面部分的部分最後會被切割下來以形成一結構,其中該 引線以不連續之方式設置以互相垂直。換言之,在該引線 框中,該似陸塊之傳導部分分別由其對應引線之部分形成 於各該引線互相交叉之處,並以點陣型態設置於一被該框 部分包圍之區域内。因此,類似上述態樣之引線框所產生 20 的功效是可以獲得的。 圖式簡單說明 第1A至1C圖例示一習知引線框以及使用該引線框之 半導體裝置的構造;

Rpl和RP2後,具有第3圖中所示之圖案的該引線以及該凹 面部分36,藉由蝕刻(如濕式蝕刻)被同時形成(第8B圖)。 再者,該蝕刻光阻(RP1和RP2)被移除以完成具有如第 4八圖下半段所示之結構的該底座31(第8C圖)。接下來的步 10驟與第4B圖以後之圖示所示者相同。 根據弟8圖所示之方法,由於該底座31的形成以及該凹 面部分36的形成是以單一步驟完成的,所以與上述實施例 (第3以及4A至4D圖)所使用之製程比較起來,此一製程被簡 化了。 15 【圖式簡單說明】 第1A至1C圖例示一習知引線框以及使用該引線框之 半導體裝置的構造; 第2A和2B圖例示根據本發明一第1實施例做成之引線 框的構造; 20 第3圖為一平面圖,示範一製造第2A和2B圖中之該引 線框的方法; 第4A至4D圖為橫斷面圖(部分平面圖),顯示在第3圖中 之方法之後所採行的步驟; 第5圖為一平面圖,例示一在第2 A和2B圖中之該引線 17 200414473 框中設置具有任意尺寸之晶片(晶片安裝區域之設置)的範 例; 第6圖為一平面圖,例示另一在第2A和2B圖中之該引 線框中設置具有任意尺寸之晶片(晶片安裝區域之設置)的 5 範例; 第7A至7C圖概略顯示一使用第2A和2B圖中之該引線 框的半導體裝置;以及 第8A至8C圖為橫斷面圖,示範另一製造第2A和2B圖中 之該引線框的方法。 10 【圖式之主要元件代表符號表】 10…帶狀引線框 30···引線框 11…外框部分 31…底座 12…内框部分 32…框部分 13…導孔 33…似陸塊之傳導部分 14…晶粒座部分 34…金屬薄膜 15…支撐條 35…黏合膠帶 16…光束狀引線 36…凹面部分 16a…内引線部分 LD…引線 16b…外引線部分 MR,MR1-MR4…半導體元件 20,40…半導體裝置 (晶片)安裝區域 21,41…半導體元件(晶片) MP…金屬板 22,42…銲線 23,43···密封樹脂 RP1,RP2···光阻圖案 18
