第1圖係用於說明第1實施形態之半導體裝置之圖。 弟2 Q至弟1 2圖係用於g兌明本實施形態之半導體裝置之 製造方法之圖。 本貫施形態之半導體裝置之製造方法係在集合體1 〇 形成配線2 0,外界端子3 0以及多層樹脂層。集合體 1 〇具有多個半導體元件1 2。集合體1 〇也可以爲矽晶 片(silicon wafer )。在各半導體元件ι2形成著多個電 極1 4。藉由將集合體1 〇切斷成個別之半導體元件1 2 ,即可將半導體元件1 2做爲半導體晶片。第1圖係詳細 表示含有切割成個別半導體元件1 2之前之集合體1 〇之 半導體裝置集合體之圖。 經濟部智慧財產局員工消費合作社印製 本實施形態之半導體裝置係將第1圖所示之半導體裝 置切割而成者。半導體裝置1包含各個半導體元件(半導 體晶片)1 2,配線2 0,外界端子3 0 ,以及多層樹脂 層(第1圖中爲第1樹脂層40與第2樹脂層100)。 而且,在多層樹脂層之中至少一層樹脂層(第1圖中爲全 部樹脂層)係避開半導體元件1 2之端部而形成。半導體 裝置1因爲其封裝尺寸大約等於半導體晶片,所以可依 C S P分類,或可謂具有緩和應力之功能之倒裝晶片。 半導體元件1 2在一面(有效面)形成有多個電極 1 4。多個電極1 4在半導體元件1 2之平面形狀爲矩形 (正方形或長方形)時,至少沿著一邊(含相對之一邊或 本紙張尺度適用中.國國家標準(CNS ) A4規格(210 X 297公釐) 13- 515064 A7 B7 五、發明説明(11) (請先閲讀背面之注意事項再填寫本頁) 所有邊)形成。或也可以在半導體元件1 2之一邊之面中 央形成多個電極1 4。在半導體元件1 2 ,避開電極1 4 ,形成氮化矽(S i N ),氧化矽(S i〇2 ),氧化鎂等 之鈍化膜(p a s s i v a t i ο n f i 1 m ) 1 6。鈍化膜1 6爲電氣絕 緣膜。鈍化膜1 6與本實施形態之多層樹脂層不同,也可 以用樹脂以外之材料形成。鈍化膜1 6也可以避開電極 1 4之至少電極1 4之一部分而形成於半導體元件1 2之 全面。 配線2 0係在半導體元件1 2之電極1 4所形成之面 ,而電連接到電極1 4。配線2 0大多由多層所構成。例 如,可以層合銅(Cu),鉻(Cr),鈦(T i),鎳 (N i ),鈦鎢(T i W ),金(A u ),鋁(A 1 ), 鎳釩(N i V ),鎢(W )之任一種以形成配線2 0。在 電極1 4形成之半導體元件1 2之端部時,則將配線2 0 拉入半導體元件1 2之中央方向。藉由連接到各電極1 4 而形成配線2 0,在半導體元件1 2之表面即形成配線圖 案。 經濟部智慧財產局員工消費合作社印製 如第1圖所示,外界端子3 0係避開電極1 4之正上 方而形成於配線2 0上面。詳細地說,外界端子3 0係形 成於配線2 0之例如表面部2 2。表面部2 2之面積形成 得比由電極1 4拉出之部分(線)更大。外界部分3 0係 避開電極1 4之正上面形成,所以施加於外界端子3 0之 應力不至於直接施加於電極1 4。外界端子3 0爲例如焊 球等部件,係用於與電路基板電連接。

),聚苯並 B惡哗(P B 〇,polybenzoxazole )等形成。 第1樹脂層4 0係形成於包含於配線2 0下面之區域 。詳細地說,第1樹脂層4 0係形成於集合體1 0上面, 第1樹脂層4 0上面形成有表面部2 2及與其連接之線( line )。換言之,第1樹脂層4 0至少形成於配線2 0與半 導體1 2之間。 第2樹脂層1 0 0係由1層或多層形成。第2樹脂層 1 0 0係形成於含有配線2 0上面之區域。第2樹脂層 1〇0也可以用與上述第1樹脂層4 0相同之材料形成, 至少有一層具有緩和應力之功能也可以。或者,第2樹脂 層1 0也可以與第1樹脂層4 0不同之材料來形成。 經濟部智慧財產局員工消費合作社印製 在第1圖所示之例子中,第2樹脂層1〇〇包含最上 層6 0與最下層5 0。最上層6 0及最下層5 0也可以用 不同材料形成之。最上層6 0之材料以使用可在上述第1 樹脂層4 0使用之材料爲宜,與其使用構成第1樹脂層 4 0及第2樹脂層1 0 0之其他層(最下層5 0 )之材料 ,不如使用楊氏模量(Y 〇 u n g ’ s m 〇 d u 1 u s )低之材料更佳。 配線2 0之一部分與電極1 4連接,並由該處拉到第 1樹脂層4 0上面。表面部2 2係形成於第1樹脂層4 〇 本紙張尺度適用中國國家標準(CNS ) A4規格(210 X 297公釐) '' -15- 515064 A7 ___ B7 五、發明説明(13) (請先閲讀背面之注意事項再填寫本頁) 上面。第1樹脂層4 〇係露出電極1 4而形成於集合體 1 0上。詳細地說,在集合體1 〇之鈍化膜1 6上面形成 有第1樹脂層4 0。 最下層5 0爲耐焊劑者(solder-resist ),而形成覆蓋 著配線2 0。此時,最下層5 0係避開配線2 0中之表面 部2 2而形成。另外,最下層5 0也可以形成於第1樹脂 層4 0上面。 如第2樹脂層爲單層之構造時,最上層6 0也可以代 替最下層5 0形成覆蓋配線2 0。最上層6 0係形成於外 界端子3 0之根部周圍。或是去除外界端子3 0之前端部 形成覆蓋外界端子3 0之側部也可以。無論如何,由最上 層6 0之一部分被去除,因此外界端子3 0至少露出其前 .端部。 此外,第2樹脂層1 0 0之熱膨脹係數可以比第1樹 脂層4 0大。藉此,可以緩和由熱應力施加於外界端子 3 0之應力等。 本實施形態之半導體裝置之形式方式爲第1樹脂層 經濟部智慧財產局員工消費合作社印製 4 0之平面形狀位於半導體元件1 2之外周更內側。詳言 之,即第1樹脂層4 0係避開半導體元件1 2之端部形成 。此時,如第1圖所示,第2樹脂層1 0 0也可以避開半 導體元件1 2之端部形成。半導體裝置1之第1樹脂層 4 0及第2樹脂層1 0 0之端面也可以成爲由例如後述之 曝光技術,印刷技術或噴墨方式等形成之端面,或如第1 圖所示,在離開半導體元件1 2之方向,成爲如同各樹脂 本紙張尺度適用中.國國家標準(CNS ) A4規格(210X297公釐) -16- 515064 A7 B7 五、發明説明(14) 層之平面形狀變小那樣附有楔形狀之傾斜面也可以。 (請先閲讀背面之注意事項再填寫本頁) 藉此,第1樹脂層4 0及第2樹脂層10 0之端面會 位於半導體裝置1之外周更內側,所以可以抑由半導體元 件1 2之剝離。 另外,在本實施形態中,只要例如第1樹脂層4 0係 避開半導體元件1 2之端部形成,則第2樹脂層1 0 0也 可以形成覆蓋半導體元件1 2之端面。此時,也可以形成 只有第2樹脂層1 0 0之最上層6 0覆蓋半導體元件1 2 之端部。尤其是,如果以楊氏模量比其他樹脂層(第1樹 脂層4 0及第2樹脂層1 0 0之最下層5 0 )爲低之材料 形成最上層6 0時,即可防止在切斷區域7 0中之半導體 元件1 2之缺失,同時抑制該缺失之進行以及抑制第1樹 脂層40及第2樹脂層100由半導體元件12之剝離。 此外,不必將最上層6 0避開半導體元件1 2之端部來設 置即可,所以可以簡單的工程製造半導體裝置。 經濟部智慧財產局員工消費合作社印製 下面要參照第2圖至第1 2圖說明本實施形態之半導 體裝置之製法。在本實施形態中,多層樹脂層之中至少將 一樹脂層(例如至少第1樹脂層4 0 )避開切斷區域7 0 形成之。 如第2圖至第5圖所示,形成第1樹脂層4 0,配線 2 0及第2樹脂層1 〇 0之1之最下層5 0。 首先,準備具有多個電極1 4且至少避開電極1 4之 一部分形成有鈍化膜1 6之集合體(參照第8圖)。 然後,形成用於形成配線2 0之第1樹脂層4 0。第 本紙張尺度適用中國國家標準(CNS ) A4規格(210 X 297公釐) -17- 515064 A7 _____ B7 五、發明説明(15) (請先閲讀背面之注意事項再填寫本頁) 1樹脂層4 0也可以利用曝光技術形成。例如,如第2圖 所示,在電極1 4上面及集合體1 〇上面(詳細地說係在 鈍化膜1 6上面)整面設置第1樹脂層4 0。第1樹脂層 4 0之材料可以使用感應到能量(光,紫外線或輻射線等 ).時會變性之樹脂,例如感光聚合物(photopolymer )等 。做爲第1樹脂層4 0之材料,可以使用照射能量( e n e r g y )時,溶解性會增加者(正型)或溶解性會減少者 (負型)皆可。 第1樹脂層4 0中,如第3眉所示,形成使電極1 4 露出之孔4 4,同時在切斷區域7 0形成開口部4 2。孔 4 4係形成於每一電極1 4。開口部4 2係沿著集合體 1 0之切斷區域7 0整體開口形成。換言之,開口部4 2 係沿著集合體1 0之中相鄰接之半導體元件1 2之境界線 形成。 經濟部智慧財產局員工消費合作社印製 例如,第2圖所示,將形成有開口 8 2,8 4之遮罩 8 0配置於第1樹脂層4 0之上方並照射能量9 0。如第 2圖所示,在此,如第1樹脂層40之材料屬於照射能量 即增加溶解性之材料時,則將開口 8 2,8 4配置於開口 部4 2及孔4 4之形成區域上。與此不同地,如第1樹脂 層4 0之材料屬於照射能量即減少溶解性之材料時,即覆 蓋開口部4 2及孔4 4之形成區域上,而在其他之區域上 配置開口。然後藉由顯影,如第3圖所示,形成開口部4 2與開口 8 2相對應,設置露出電極1 4之孔4 4與開口 8 4相對應。在使用上述之能量照射技術(曝光技術等) 本紙張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) ' 一 -18- 515064 A7 ____ B7 五、發明説明(16) 時,能量會由遮罩8 0之開口 8 2 , 8 4繞進,所以開口 部4 2及孔4 4之開口端部須以曲面形成。 (請先閲讀背面之注意事項再填寫本頁) 如第4圖所示,將配線2 0形成於由電極1 4到第1 樹脂層4 0上面。配線2 0也可以藉由光刻法,噴鍍法或 電鍍處理來形成。要在配線2 0之一部分形成表面部2 2 時,須將表面部2 2形成於第1樹脂層4 0上面。配線 2 0也形成於第1樹脂層4 0之孔4 4內面。 藉由將配線由電極1 4拉入,外界端子3 0即可避開 電極1 4之正上方來形成。另外,藉此,亦可將外界端子 3 0設置於半導體元件1 2之有效區內。亦即,可以進行 間距(phch )轉換。因此,在配置外界端子3 0時,在有 效區內,即可以提供一定表面之區域,設置外部端子3 0 之位置之彈性增加許多。例如,由於將配線2 0在必要之 位置彎曲,也可將外界端子3 0排成格柵狀。 經濟部智慧財產局員工消費合作社印製 如第4圖所示,形成最下層5 0。例如,將最下層 5 0設置於第1樹脂層4 0及配線2 0上整面。此時,在 形成於第1樹脂層4 0之開口部4 2也塡補最下層5 0之 材料。此項工程宜於第1樹脂層4 0硬化後才進行。 如第5圖所示,在最下層5 0使配線2 0之一部分( 表面部2 2 )露出,同時爲避開切斷區域7 0形成而形成 開口部5 2。此也可以在第1樹脂層4 0進行之工程相同 之方法形成。例如,第4圖所示,將形成有開口 1 8 2, 1 8 4之遮罩1 8 0配置於最下層5 0之上方以照射能量 9 0。此時,如第4圖所示,如最下層5 0之材料爲照射 本紙張尺度適用中國國家標準(CNS ) A4規格(21〇Χ297公釐) -19- 515064 A7 B7 _ 五、發明説明(17) 能量時會增加溶解性者時,則在開口部5 2及孔5 4之形 成區域上配置開口 1 8 2, 1 8 4。與此不同地,做爲最 (請先閲讀背面之注意事項再填寫本頁) 下層5 0之材料,也可以使用照射能量時,溶解性會減少 之材料。然後,藉由顯影,如第5圖所示,對應於開口 1 8 2,去除塡補於開口部4 2之部分並形成開口部5 2 。另外,對應於開口 1 8

0上所形成之一部分(表面部 22)形成外界端子30。形成最下層50之後,在由最 下層5 0露出之配線2 0之一部分(表面部)設置外界端 子3 0。由於形成最上層5 0,所以可易簡單設置外界端 子3 0。藉由將外界端子3 0設置於第1樹脂層4 0上面 ,即可以將第1樹脂層4 0做爲應力緩和層以緩和施加於 外界端子3 0之應力。也可以將焊球等設置於表面部2 2 以形成外界端子3 0。或在表面部2 2上面設置焊膏( solder cream )使其融解而藉由表面張力成爲球狀也可以。 如第6圖所示,形成最上層6 0。至少露出外界端子 3 0之前端部來形成。也可以將最上層6 0至少設置於外 界端子3 0之根部周圍。藉此,即可將最上層6 0做爲應 本紙張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) -20- 515064 A7 B7 五、發明説明(18) 力緩和層緩和施加於外界端子3 0之應力(熱應力)。 (請先閱讀背面之注意事項再填寫本頁) 例如,將以非感光性之樹脂做爲材料所構成之最上層 6 0設置於最下層5 0及外部端子3 0上面。此時,開口 部4 2,5 2也塡補最上層6 0之材料。然後,藉由利用 電漿等之乾蝕刻將一部分實質上去除使外界端子3 0至少 露出前端部。同樣地,也去除塡補於開口部4 2, 5 2之 部分,再形成開口部6

1〇切斷成個體。亦即,將含有多個半導體元件1 2之集 合體10之多個半導體裝置之集合體個體化,以形成每一 半導體元件1 2之半導體裝置1。第7圖表示要切斷時之 整個集合體1 0之剖面圖,第8圖表示要切斷時之整個集 合體1 0之圖。 集合體1 0係由形成有電極1 4之面側切斷。例如, 如第7圖所示,至少在避開第1樹脂層4 0而形成之切斷 區域7 0配置刀片(blade ) 1 1 0來切斷之。可以使刀片 經濟部智慧財產局員工消費合作社印製 1 1 0高速旋轉以切斷集合體1 0。此時,也可以將集合 體1 0黏貼於膠帶(tape,未圖示)來切斷。 藉此,至少可以沿著避開第1樹脂層4 0而形成之切 斷區域7 0切斷,所以可以抑制由於切斷而引起之半導體 裝置1之端部之缺失。如此一來,即可防止半導體裝置1 之第1樹脂層4 0及第2樹脂層1 0 0之剝離。進而製造 可靠性高之半導體裝置。 其次,如第9圖至第1 2圖所示,要說明本實施形態 本紙張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) ' — -22 515064 A7 B7 五、發明説明(20) 之半導體裝置之製造方法。 (第1變形例) 如第9圖所示,本變形例中,.將避開切斷區域7 0而 形成之至少一樹脂層(例如至少第1樹脂層4 0 )以噴墨 方式形成之。藉此,可以利用簡單之工程,將第1樹脂層 4 0設置於必須避開切斷區域7 0之區域。另外,除了避 開切斷區域7 0之外,還避開電極1 4設置第1樹脂層 4 0 〇 利用噴墨方式時即須應用將噴墨印表機上實用化之技 術,因而可以將墨水以高速而耗無浪費節約地塡充。 第9圖所示之噴墨頭1 1 2係在例如噴墨印表機上實 用化者,可使用利用壓電元件之壓電噴射式,或使用電熱 轉換器做爲能量產生元件之A

2開口之區域,以遮罩1 2 2之高度,均勻塡補塗漿 46。此時,藉由移走遮罩122,即可以在避開切斷區 域7 0及電極1 4之必要區域形成第1樹脂層4 0。 (第3變形例) 經濟部智慧財產局員工消費合作社印製 如第1 1圖所示,本變形例係事先製作至少一樹脂層 (例如第1樹脂層4 0 )之圖案而形成於另一構件1 3 0 ,再複製於集合體1 0而形成於避開切斷區域7 0之區域

(第4變形例) (請先閱讀背面之注意事項再填寫本頁) 第1 2圖爲表示本變形例之外界端子3 0之周圍之圖 。本變形例爲本實施形態之半導體裝置之變形例。在本變 形例中,設置於包含最上層1 6 0之第2樹脂層1 0 2之 外界端子3 0周圍部分之形態與上述有別。 例如,將外界端子3 0形成球狀時,設置於表面部 2 2之外界端子3 0之接合部之平視徑D 2與外界端子3 0 之直徑D有D 2 S D之關係。最上層1 6 0之形成方式必須 使該種接合部之平視徑D 2與由外界端子3 0之最上層 1 6 0露出部分之平視徑D i呈D i < D 2。亦即,可以將 最上層1 6 0形成覆蓋外界端子3 0之周圍俾外界端子 3〇不致妨礙其與電路基板之電連接。此時,如第1 2圖 所示,覆蓋最上層1 6 0之外界端子3 0之部分也可以比 最上層1 6 0之其他面突出。 經濟部智慧財產局員工消費合作社印製 如此一來,在將外界端子3 0電連接到電路基板時, 可以確實保護兩者之電連接部。並可進一步緩和施加於與 外界端子3 0之配線2 0之接合部之應力以防止接合部發 生裂紋。因此,可以提供更具可靠性之半導體裝置。另外 ,本變形例之半導體裝置之製造方法與上述相同也可以。 (第2實施形態) 第1 3圖至第1 5圖係用於說明本實施形態之半導體 裝置及其製造方法之圖。第1 3圖爲含有本實施形態之半

5圖爲含有本實施形態之變形例之半導體裝置的集 合體(半導體晶元)之剖面。 本實施形態之半導體裝置包含各個半導體元件(半導 體晶片)1 2,配線2 2 0 ,外界端子3 0及多層樹脂層 (第1 3圖中爲第1樹脂層240及第2樹脂層1 04) 。而且,多層樹脂層之中至少一樹脂層(第13圖中爲全 部樹脂層)係避開半導體元件1 2而形成者。半導體裝置 2之第1樹脂層2 4 0之形態與第1實施形態不同。另外 ,第2樹脂層1 0 4可以形成單層,但在第1 3圖所示例 子中,係由最上層6 0及最下層2 5 0之多層所構成。此 外,半導體裝置2係切斷第13圖所示之半導體裝置而成 者。除了下面之說明以外,可以爲與第1實施形態相同之 形態。 經濟部智慧財產局員工消費合作社印製 本實施形態之半導體元件1 2之端部形成有電極1 4 。第1樹脂層2 4 0係形成於半導體元件1 2之中央部。 換言之,第1樹脂層2 4

〇之形成區域抑制於小範圍,因此,可以緩和施加於 外界端子3 0之應力。 又如此地形成第1樹脂層2 4 0,因此,即可以避開 切斷區域7 0形成第1樹脂層2 4 0。另外,配線2 2 0 只要與第1實施形態一樣形成於電極1 4至第1樹脂層 2 4〇即可。 另外,第1樹脂層2 4 0之熱膨脹係數也可以小於第 2樹脂層1 0 4。藉此,可以緩和由熱應力施加於外界端 子3 0之應力。 經濟部智慧財產局員工消費合作社印製 本實施形態之半導體裝置之第2樹脂層1 0 4之形成 方式係使其位於比半導體元件1 2之外周更內側。詳言之 ,即第2樹脂層1 0 4係避開半導體元件1 2形成之。其 他之形態也可以與第1實施形態相同。 如第1 5圖所示,做爲本實施形態之變形例,也可以 將第2樹脂層1 〇 4之最上層6 0形成覆蓋半導體元件 1 2之端部。尤其是最上層6 0以使用比構成第1樹脂層 2

時形成最下層2 5 0。藉由在最下層2 5 0形成露出表面 部2 2 2之孔2 5 4 ,即可簡單地設置外界端子3 0。此 外,形成最下層2 5 0之工程也可以省略。 與第1實施形態一樣形成外界端子3 0與最上層6 0 ,並在切斷區域7 0形成開口部2 5 2,6 2。然後,沿 著切斷區域7 0切斷集合體1 〇。藉此,可以抑制半導體 裝置之多層樹脂層之剝離。 經濟部智慧財產局員工消費合作社印製 此外,也可以於設置最上層6 0於集合體1 0 〇之全 面後,僅去除最上層6 0之中覆蓋外界端子3 0之部分。 亦即,亦可以留下最上層6 0以覆蓋集合體1 〇之切斷區 域。如此一來,即可以簡單之工程形成最上層6 0 ° 另外,在本實施形態中,也可以使用上述實施形態之 第1至第4變形例以製造半導體裝置。 本紙張尺度適用中國國家標準(CNS ) A4規格(210 X 297公嫠) 515064 A7
