Description
1248186 九、發明說明: 【發明所屬之技術領域】 本發明涉及一種用於利用在商業中已知爲球形-引線 接合器(BaU-Wire Bonder)的引線接合器(Wire Bonder)來 產生楔形-楔形(w e d g e - w e d g e )引線連接的方法。 【先前技術】 引線接合器是一種將被安裝在基板上的半導體晶片進 行引線接合的機器。在商業中,存在兩種不同類型的引線 接合器,一種爲球形-楔形引線接合器,簡稱爲球形引線-接合器,另一種爲楔形-楔形引線接合器,簡稱爲楔形-引 線接合器。 球形-引線接合器具有一個被夾到操縱桿(horn)的頂端 的毛細管(capillary)。毛細管將引線連接到半導體晶片的連 接點上和基板上的連接點上,以及引導這兩個連接點之間 的引線。在產生半導體晶片上的連接點和基板上的連接點 之間的引線連接時,伸出毛細管的引線的末端被首先熔化 成球。然後,這個球被藉由壓力和超音波連接到半導體晶 片上的連接點。藉由這種方式,來自超音波轉換器的超音 波被施加到操縱桿上。這個過程稱爲球接合。然後,引線 被拉到所需的長度,形成引線環並焊入(熱壓縮接合)基板 上的連接點。這個最後的子過程稱爲楔形接合。在將引線 連接到基板上的連接點上之後,引線被剝離且可以開始下 一輪的接合。 楔形-引線接合器具有引線引導和連接工具,其將引線 1248186 連接到半導體晶片上的連接點和基板上的對應連接點。在 產生半導體晶片上的連接點和基板上的連接點之間的引線 連接時,引線引導和連接工具所提供的引線的末端被藉由 壓力和超音波連接到基板上的連接點。然後,引線被拉到 所需的長度,形成引線環並焊入基板上的連接點。這兩個 子過程稱爲楔形接合。在將引線連接到基板上的連接點上 之後’引線被剝離或切斷且可以開始下一輪的接合。一般 而言’楔形-楔形連接進行這樣的引線連接;在兩個連接點 上’通吊在較局的溫度下’從毛細管伸出的對應引線被經 由壓力和超音波接入對應的連接點,而沒有前面所述的熔 化爲球。 楔形-引線接合器的接合頭與球形-引線接合器的接合 頭之間有本質的不同,因爲對於楔形-楔形接合過程,將被 連接到第一連接點上的引線的末端總是呈將進行的引線連 接的方向。因此,對於楔形-引線接合器,操縱桿必須可旋 轉地安置在垂直軸上,其中在操縱桿的頂端固定引線引導 和連接工具。楔形-引線接合器的接合頭必須使引線引導和 連接工具的移動具有總共五個自由度,而球形-引線接合器 的接合頭只需使毛細管的移動具有總共三個自由度。 【發明內容】 本發明是基於這樣的發現而作出的:在產生第二楔形 連接之後進行引線的剝離時,球形引線接合器也能夠用於 產生楔形-楔形引線連接,使得伸出毛細管的引線指向待進 行的下一引線連接的方向。 1248186 因此,根據本發明,提供了以如下的方式對球形-引線 接合器進行安排爲了藉由剝離引線來完成楔形-楔形引線 連接的產生和準備伸出毛細管的引線以產生下一楔形-楔 形引線連接,在將引線連接到第二連接點之後,進行下述 的步驟: -計算水平面上的二維向量V,其從毛細管的在待進行的 下一楔形-楔形引線連接的第一連接點上的所需作用點 指向毛細管的在待進行的下一楔形-楔形引線連接的第 二連接點上的所需作用點,以及 -在將引線連接到第二連接點上之後,將毛細管沿著由向 量V與垂直線所形成的平面中的行進路徑移動。在將引 線連接到第二連接點上時,像通常那樣產生預定斷開點 ,其中引線將在到達行進路徑的末端時剝離。 基本上,毛細管的行進路徑包括四個連續的行進移動 a) 將毛細管升高預定的距離△ z !; b) 以向量v所限定的方向,將毛細管在水平方向上移 動預定的距離△ Wi ; c) 將毛細管降低預定的距離△ z2 ;以及 d) 以向量v所限定的方向,將毛細管在水平方向上移 動預定的距離△ W2。距離△ W2形成的尺寸使得引線剝離。 在進行步驟a、b和C中毛細管的移動時引線夾張開且 在引線被剝離之前將引線與向量v的方向對準。引線在預 定的斷開點上剝離’使得引線從毛細管伸出,其被與向量 -7- 1248186 V的方向對準。 步驟a、b和c中毛細管的移動爲水平或垂直移 些移動也可以互相疊加’以避免突然的停止以及毛 相關振盪,其具有使毛細管的行進時間變短的優點 如上所述,球形-引線接合器的接合頭具有這樣 管,其引導引線並且使毛細管的移動具有三個自由 座標的笛卡爾系統的X、y和Z方向上的移動。滿足 求但是在設計上基本不同的不同接合頭在專利EP 、US 5330089 或 US 6460751 中有描述。 本發明的基本原理也可以用於這樣的應用:藉 將引線連接到基板上、然後連接到半導體晶片上的 產生引線連接。對於這些應用,通常需要經由必須 施加到半導體晶片上的附加引線材料來補強引線與 晶片之間的連接。在球形連接被首先施加到半導體 的連接點且不形成引線連接而立即剝離引線的情況 用上述的應用。在商業中,所產生的球形連接被稱;| (bump)”或”球形凸起”。然後,產生球形-楔形引線連 中伸出毛細管的引線被熔化爲球且被連接到基板上 點,然後拉出所需的引線長度,經由這種方式,形 ί哀和引線被連接到凸起上’作爲模形接合。這種引 的特徵在於其具有位於兩個末端的”球”或”凸起”。 中,這種方法已知爲球形-凸起-反向-環(B a 11 - B u m p - R L ο ο p)方法。本發明簡化了對於這種類型應用的引線 產生,其中本發明使伸出毛細管的引線首先被連接 動。這 細管的 〇 的毛細 度,即 這些需 317787 由首先 方式來 先前被 半導體 晶片上 中,採 I ”凸起 接,其 的連接 成引線 線連接 在商業 e v e r s e - 連接的 到施加 1248186 在半導體晶片上的凸起上’作爲楔形連接,然後被拉出所 需的引線長度’藉由這種方式立即形成引線環並將引線連 接到基板上的連接點上,作爲楔形連接。從而,進行兩種 不同的程序。 對於桌一種程序’半導體晶片上的所有連接點都首先 以已知的方法設置凸起。然後,設置半導體晶片與基板之 間的引線環,作爲如上所述的楔形-楔形連接。 對於第二種程序,從開始到結束依次完整地產生一個 引線連接。這種引線連接的產生的特徵在於以下的步驟: 將伸出毛細管的引線熔化爲球("球的形成”), 計算水平面上的二維向量V,其從毛細管在半導體晶 片的連接點上的所需作用點指向毛細管在基板的連接點i 的所需作用點, 球的形成通過以下方式: -將球連接到半導體晶片上的連接點,以及 -將毛細管沿著由向量V與垂直線所形成的平面中的行進 路徑移動,從而在行進路徑的末端剝離引線。在此,0 進路徑也包括如第一不例所描述的a到d的行進g重力 凸起被連接到半導體晶片上的連接點且伸出毛細管的弓丨 線指向將產生的引線連接的方向。 -將毛細管移回到剛產生的凸起上, -將伸出毛細管的引線連接到凸起上,從而建立楔形連胃 , '將引線拉出所需長度’從而’像通常那樣,引線形成環 1248186 ’且將引線連接到基板上的連接點上,作爲楔形連接。 【實施方式】 第1圖示出理解本發明所必需的引線接合器的若干部 分的示意性側視圖。球形-引線接合器包括接合頭2,該接 合頭2以及操縱桿3可藉由兩個驅動器在水平X y平面1中 移動,其中在操縱桿3的頂端夾有毛細管4。毛細管4具 有縱向鑽孔,藉由該鑽孔饋送引線5。操縱桿3能夠藉由 第三驅動器繞水平軸6旋轉。因此,這三個驅動器使毛細 管4的頂端的移動從一個位置A移動到任一位置B。根據 這種設計,毛細管4的自由度的數目n總共爲n = 3。此外 ,電極1 2被連接到接合頭2上,藉由該電極,可以將伸出 毛細管的引線熔化爲球。對這種電極的細節描述在台灣專 利申請TW 200404026和1222388中有示例。 第2圖示出具有若干安裝在基板7上的半導體晶片8 的基板7的示意性平面圖。基板7也可以爲半導體晶片。 每個半導體晶片8具有預定數目的連接點9.1、9.2等,每 個連接點藉由引線連接1 0. 1、1 0.2等與基板7上的對應的 連接點1 1 . 1、1 1 .2等進行電連接。 現在根據第3圖和第4A圖至第4E圖對根據本發明的 方法進行詳細的描述。第3圖示出了被第2圖的虛線包圍 的部分。第3圖的左側所示出的引線連接1 0 . 1已進行到這 樣的程度:藉由球形-引線接合器的毛細管4,引線環已從 半導體晶片8上的第一連接點9 . 1延伸到基板7上的對應 的第二連接點1 1 . 1,且末端被焊入兩個連接點9 . 1和1 1 . 1 -10- 1248186 。但是,從毛細管4中出來的引線5還未與引線連接〗〇 · 1 分開。下一步要做的是產生兩個連接點9 · 2和η . 2之間的 引線連接1〇·2。因此,向量v = (Vx,Vy,Vz)的兩個分量Vx和 vy確定爲位於水平Xy平面中,且從第—連接點9 2指向第 二連接點1 1 · 2 ··向量V連接各個連接點9 · 2和1 1.2上的毛 細管4的所需作用點。一般而言,兩個連接點9.2和!丨· 2 位於不同的Z咼度,向量V的Z分量vz不重要。因此,兩 個分量VX和Vy限定了位於水平xy平面中的二維向量Vl。 當第一連接點9 · 2上的毛細管4的所需作用點的座標用(X i, yi,Zl)指定且第二連接點η·2上的毛細管4的所需作用點 的座標用(X2, y2, ζ2)指定時,則這導致向量Vl爲Vl = (X2-Xl, 的結果。同樣示出了從實際還未完成的引線連接10· 1 的連接點1 1.1出來的向量V2。向量V2與向量Vl平行且示 出毛細管4所經過的水平X y平面i中的行進方向,其將在 下面的步驟描述。 第4A圖至第4E圖示出連續瞬態圖中的第二連接點1 1 · 1 、引線5和毛細管4,其示出引線5與引線連接1 〇 · 1的分 離。引線5的分離使得:在剝離之後,伸出毛細管4的引 線的末端與向量v i或v2平行。附圖示出與向量v2平行的 垂直平面中的垂直部分。箭頭表示毛細管4的行進方向。 第4 A圖示出在將引線5連接到第二連接點1 1 · 1之後 緊接的狀況。進行下述的步驟: -毛細管4被升高預定的距離△ z i。這個狀況在第4B圖中 示出。 -11- 1248186 -毛細管4被以向量v2所限定的方向在水平方向上移動預 ' 定的距離Aw!。這個狀況在第4C圖中示出。 -毛細管4被降低預定的距離△ z 2。這個狀況在第4 D圖中 示。一般而言,距離△ z 2小於距離△ z 1 ’因此,在毛細 管4的後面的行進移動中’引線5沒有與半導體晶片8 摩擦或只與其產生小摩擦。 -毛細管4再次被以向量v2所限定的方向在水平方向上移 動預定的距離△ w2。距離△ w2形成的尺寸使得引線剝離 。第4E圖示出在剝離引線5之後的狀況。 毛細管4在水平方向上移動距離△ w i和毛細管4在後 來降低距離△ z2具有這樣的效果:伸出毛細管4的引線的 末端在水平方向上遠離毛細管4的頂端突起。在向量v i的 方向上的行進方向具有這樣的效果:引線的末端爲將進行 的下一引線連接的方向。 剝離引線5的過程步驟具有這樣的效果:伸出毛細管 4的引線的末端與向量Vl平行。毛細管4現在被移動到將 進行的下一引線連接10.2第一連接點9.2且引線5被連接 到連接點9 · 2上。引線5的連接通過預定接合力和超音波 被施加到毛細管4上來完成。由於引線的末端先前沒有形 成球’所以引線5與連接點9 · 2之間的連接爲楔形連接。 弓丨線現在以通常的方式被拉出所需的長度,形成引線環且 連接到第二連接點1 1 · 2上。同時或者在後來,對將進行的 下一引線連接丨〇 · 3計算向量v i且根據上述的過程步驟剝離 引線。 -12- 1248186 在完成半導體晶片與基板之間的最末引線連接時,對 下一半導體晶片與基板之間將進行的第一引線連接確定向 量V。經由這種方式,所有的半導體晶片可以容易地藉由 楔形-楔形連接接合。 只存在一個問題,在開始產生時,伸出毛細管的引線 的末端沒有指向與將進行的第一引線連接對應的向量V1的 方向。這個問題可以經由以下的方式解決:或者對於引線 連接,引線的末端形成爲球且引線被連接爲球形連接,或 者引線被連接到基板上的合適位置上,根據本發明的過程 步驟對將進行的第一引線連接計算向量V i和剝離引線。伸 出毛細管的引線的末端現在指向向量V i的方向且第一引線 連接能夠產生爲楔形-楔形連接。 本發明的一個重要優點在於省去了引線球的形成,這 整體來說縮短了循環時間。另一個優點是所產生的楔形-楔 形連接的環高度小於球形-楔形連接。 第5A圖示出根據上面基於第4A圖至第4E圖所述的 方法、毛細管4 (第4 A圖)在向量v i和垂直線(g[] z方向)所 形成的平面中所經過的行進路徑1 3,其在將引線5連接到 第二連接點1 1 · 1上直到引線5被剝離之後。這個行進路徑 包括兩個垂直和兩個水平的移動,其距離由AZl、Awi、 △ z 2和△ w 2限定。根據本發明的方法也可以將毛細管4的 行進移動進行稍微的修改,其特別被最佳化爲在行進移動 期間消除停止的效果。在第5B圖至第5E圖示出四個示例 。對於第5 B圖中的示例,將水平方向上的移動距離△ w t -13- 1248186 、毛細管4升高的距離△ z !和毛細管4降低的距離△ Z2疊 加··毛細管4的行進路徑1 3爲鋸齒形。對於第5 C圖的示 例,將毛細管4降低的距離△ z2與水平方向上的移動距離 △ w i疊加:毛細管4的行進路徑1 3部分爲弓形。此外, 爲了盡可能防止在毛細管4的突然停止時,毛細管4出現 不能避免的振盪以及獲得較短的循環時間,可以藉由弓形 部分來平滑行進路徑1 3中的剩下的轉角點。第5 B圖和第 5 C圖的示例中所示的行進路徑1 3被修改爲如第5 D圖和第 5 E圖所示。至少在毛細管4完全經過行進路徑1 3時,引 線5被剝離引線連接1 〇 . 1 (第2圖)。 本發明的第二實施例涉及這樣的應用:第2圖所示的 半導體晶片8上的連接點9 . 1、9 · 2等以及基板7上的連接 點1 1 · 1、1 1 · 2等之間的引線連接1 〇 . 1、i 〇 . 2等被藉由以 "凸起π的形式施加到半導體晶片8上的連接點9.1、9.2等 上的附加引線材料而補強。對於這個實施例,引線連接被 一個接一個地產生:首先,”凸起”,更確切地說爲所謂的,, 球凸起”被施加到半導體晶片8上的連接點,然後,毛細管 4以將進行的引線連接的方向移動,直到引線5被剝離, 然後毛細管4移回到凸起上,然後進行從凸起到基板7上 的連接點的楔形-楔形引線連接。現在參照第7 Α圖到第7 F 圖對第6圖所示的引線連接1 0.2的產生進行描述,其中第 7A圖至第7F圖示出與引線連接ι〇·2的方向對準的垂直面 的垂直部分,即由向量vi和垂直線所形成的平面。第7Α 圖至第7F圖還示出引線夾丨4的張開或閉合的狀況。固定 -14- 1248186 基準軸1 7用於示出向量v ,的方向上的毛細管4的各水平 位置。 第7 A圖示出在伸出毛細管4的引線被熔化爲球且連接 到半導體晶片8上的第一連接點9.2之後且在引線5被剝 離之前的狀況。在連接時,熔化的球被壓平。引線5仍然 與被壓平的球1 5連接,但是已預形成預定斷開點1 6,在 預定斷開點1 6上引線5將被剝離。毛細管4現在被升高至 所謂的尾部高度,使得在後來剝離引線5之後,伸出毛細 管4的引線5 (所謂的”尾部”)具有預定的長度。這種狀況如 第7B圖所示。毛細管4被同時向側邊和向上移動,較佳的 是沿著以預定斷開點1 6爲中心的弓形,從而這種行進移動 的水平分量指向將進行的引線連接1 0.2的方向。毛細管4 所經過的軌跡路徑如元件符號1 8所示。這個方向經由第一 連接點9 · 2和第二連接點1 1 · 2上的毛細管4的所需作用點 之間的連接線來限定。這個連接線對應於如第2圖所示的 引線連接1 〇 . 2,作爲向量v i。當沿著以預定斷開點1 6爲 中心的弓形進行移動時,預定斷開點1 6未變形且引線5還 未剝離。這個狀況如第7C圖所示。引線夾1 4現在被閉合 且毛細管4進一步遠離第一連接點9. 1移動,較佳的是沿 著連接預定斷開點1 6和毛細管4的開口的線移動。由於引 線夾1 4被閉合,所以引線5在預定斷開點1 6上被剝離。 ”球凸起π的形成現在完成了,且伸出毛細管4的引線與將 進行的引線連接1 0 · 1的方向對準。這個狀況如第7 D圖所 示。毛細管4現在移回到”球凸起"(第7 Ε圖)上且被降低 -15- 1248186 (第7F圖),且伸出毛細管4的引線藉由壓力和超音波連接 到”球凸起”上。然後,以通常的方式完成引線連接1 〇 . 2, 其中引線5被拉出預定的長度,像通常那樣形成爲引線環 並連接到第二連接點,作爲楔形連接。 本發明的基本優點在於: -環高度Η(第6圖)小於球形-楔形引線連接。 -楔形-楔形引線連接的產生無需所謂的反向移動,其是球 形-楔形引線連接所需的,以預形成引線環,使引線連接 具有所需的彎曲。經由這種方式,連接點9 · 1、9 · 2等的 空間需求降低了,這提供了連接點9. 1與相鄰設置的半 導體晶片19之間的最小距離Α小於當從連接點9.1、9.2 等開始必須進行球形連接時的距離要小的優點,這對於” 層疊的晶片π應用更是如此。 -接合周期所需的時間小於球形-凸起-反向-環方法,由於 對於每個引線連接,引線被熔化爲球只需一次而不是兩 次。 雖然已示出和描述了本發明的實施例和應用,但是對 於可從本公開中獲益的本發明的技術人員來說顯而易見, 在不脫離本發明的範圍的情況下,可以進行多種修改,而 不是上述的實施例。因此,本發明只受所附的申請專利範 圍及其等同物所限制。 【圖式簡單說明】 附圖合倂入本文件中並作爲本文件的一部分,附圖示 出了本發明的一個或多個實施例,且與詳細的說明一起解 -16- 1248186 釋本發明的原理和實現。附圖沒有刻度比例。在附圖中: 第1圖示意性地示出一球形-引線接合器; 第2圖爲示出具有若干半導體晶片的基板的示意性平 面圖; 第3圖爲第2圖的剖面圖;
