本發明提供一種燒結接合用片材及附有基材之燒結接合用片材,其適於作業效率良好地製作,並且適於在會經過半導體晶片之燒結接合之半導體裝置製造過程中之燒結製程中實現良好之作業效率。

Description
本發明係關於一種可用於半導體裝置之製造等之燒結接合用片材、及帶有基材之燒結接合用片材。
於半導體裝置之製造中,作為用以一面將半導體晶片黏晶於引線框架或絕緣電路基板等支持基板一面取得與支持基板側之電性連接之方法,已知有於支持基板與晶片之間形成Au-Si共晶合金層而實現接合狀態之方法、或利用焊料或含有導電性粒子之樹脂作為接合材之方法。
另一方面,近年來負責電力之供給控制之功率半導體裝置之普及顯著。功率半導體裝置大多情形下因動作時之通電量較大而導致發熱量較大。因此,於功率半導體裝置之製造中,關於一面將半導體晶片黏晶於支持基板一面取得與支持基板側之電性連接之方法,要求能夠實現高溫動作時可靠性亦較高之接合狀態。於採用SiC或GaN作為半導體材料來謀求高溫動作化之功率半導體裝置中,此種要求尤為強烈。並且,為了應對此種要求,提出有使用含有燒結性粒子與溶劑等之燒結接合用組合物之技術作為伴隨電性連接之黏晶方法。
於使用含有燒結性粒子之燒結接合用材料所進行之黏晶中,首先,經由燒結接合用材料於特定之溫度、荷重條件下將半導體晶片載置於支持基板之晶片接合預定部位。其後,於特定之溫度、加壓條件下進行加熱步驟以於支持基板與其上之半導體晶片之間產生燒結接合用材料中之溶劑揮發等且於燒結性粒子間使燒結進行。藉此,於支持基板與半導體晶片之間形成燒結層,使得半導體晶片電性連接並且機械性地接合於支持基板。此種技術例如記載於下述之專利文獻1、2中。

[發明所欲解決之問題]
於利用燒結接合進行黏晶之半導體裝置製造過程中,先前有時逐個半導體晶片塗佈含有燒結性粒子之糊狀組合物。然而,此種方法並無效率。
另一方面,於利用燒結接合進行黏晶之半導體裝置製造過程中,為了一次性地對複數個半導體晶片供給燒結接合用材料,例如考慮經過如下製程。首先,於單面具有黏著面之加工用膠帶或其黏著面上排列複數個半導體晶片。繼而,對加工用膠帶上之半導體晶片陣列按壓作為製作成片材形態之燒結接合用材料之燒結接合用片材來進行貼合。繼而,一面使燒結接合用片材中壓接於半導體晶片之部位殘留於該半導體晶片上,一面進行該片材體之剝離。於藉由該片材體之貼合與其後之剝離進行燒結接合用材料自片材體向各半導體晶片之轉印之情形(即,於半導體晶片上產生自周圍分離出之燒結接合用片材小片之情形)時,可獲得附有燒結接合用材料層之半導體晶片(轉印步驟)。根據此種方法,能夠一次性地對複數個半導體晶片供給燒結接合用材料。
然而,於上述之轉印步驟中,先前存在產生如下部位之情形:即便為燒結接合用片材中壓接於半導體晶片之部位亦未產生小片化(即,未自周圍分離)而自該半導體晶片剝離。此種轉印步驟並無效率,就良率較佳地製造包含半導體晶片之燒結接合部位之半導體裝置之方面而言欠佳。
又,於用以實施如上所述之轉印步驟之燒結接合用片材之製作過程中,先前存在如下情形:於燒結接合用片材之切斷步驟、或用以將燒結接合用片材形成為特定之俯視形狀之沖裁加工時,無法將燒結接合用片材適當地切斷等。此種燒結接合用片材製作製程並無效率,就良率較佳地製作燒結接合用片材之方面而言欠佳。
本發明係基於如上之情況而想出者,其目的在於提供一種燒結接合用片材及附有基材之燒結接合用片材,該燒結接合用片材適於作業效率較佳地製作,並且適於在包含半導體晶片燒結接合部位之半導體裝置之製造過程中之燒結製程中實現良好之作業效率。
[解決問題之技術手段]
根據本發明之第1態樣,提供一種燒結接合用片材。該燒結接合用片材包含含有導電性金屬之燒結性粒子及黏合劑成分,且藉由SAICAS法所測定之23℃下之剪切強度為2~40 MPa。於本發明中,所謂藉由SAICAS法所測定之剪切強度,設為於以下之條件下使用作為Daipla Wintes股份有限公司製造之裝置之SAICAS(Surface And Interfacial Cutting Analysis System)所測定之剪切強度(剪切破壞強度):關於切刃,刃寬1 mm、斜角10°及隙角10°、切刃之水平速度為10 μm/s且垂直速度為0.5 μm/s之定速度模式;以及特定之溫度。該裝置能夠對基材上之作為測定對象物之材料層實施利用切刃之斜向切削,且可由關於其切削過程中之作用於切刃之水平力與垂直力及切刃之垂直位移之資料求出材料層之剪切強度等。
此種本燒結接合用片材於包含半導體晶片之燒結接合部位之半導體裝置之製造過程中例如以如下方式使用。首先,對於排列於單面具有黏著面之加工用膠帶或其黏著面上之複數個半導體晶片按壓本燒結接合用片材並且進行貼合。繼而,一面使燒結接合用片材中壓接於半導體晶片之部位殘留於該半導體晶片上,一面進行該片材體之剝離作業。藉由此種貼合作業與其後之剝離作業來進行燒結接合用材料自燒結接合用片材向各半導體晶片之轉印,而於半導體晶片上產生作為自周圍分離出之燒結接合用片材小片之燒結接合用材料層(轉印步驟)。繼而,將附有燒結接合用材料層之半導體晶片經由其燒結接合用材料層壓接於基板來暫時固定。然後,經過加熱過程而由介存於暫時固定之半導體晶片與基板之間之燒結接合用材料層形成燒結層,從而將該半導體晶片燒結接合於基板。例如能夠以如上方式使用本燒結接合用片材將半導體晶片燒結接合於基板。
本燒結接合用片材如上所述,藉由SAICAS法所測定之23℃下之剪切強度為2~40 MPa。關於包含含有導電性金屬之燒結性粒子與黏合劑成分之組合物之片材體,本發明者等人得出以下見解:藉由上述條件下之SAICAS法所測定之23℃下之剪切強度為2~40 MPa之構成適於保持其片材形狀且獲得良好之剪裁性。例如,如下述之實施例及比較例所示。於本燒結接合用片材中,藉由上述條件下之SAICAS法所測定之23℃下之剪切強度為2 MPa以上之構成就以保持片材形狀之片材體之形式操作本燒結接合用片材之方面而言較佳。於本燒結接合用片材中,藉由上述條件下之SAICAS法所測定之23℃下之剪切強度為40 MPa以下之構成就本燒結接合用片材不會變得過硬而發揮良好之剪裁性之方面而言較佳。關於本燒結接合用片材,就其良好之剪裁性之觀點而言,藉由SAICAS法所測定之23℃下之剪切強度較佳為2~35 MPa,更佳為2~32 MPa。並且,適於獲得良好之剪裁性之本燒結接合用片材適於在其製作製程中適當地實施切斷或沖裁加工,因此適於作業效率較佳地製作。並且,適於獲得良好之剪裁性之本燒結接合用片材適於在半導體裝置製造過程中之上述之轉印步驟中,使作為自周圍分離之燒結接合用片材小片之燒結接合用材料層產生於半導體晶片上。即,本燒結接合用片材適於適當地實施一次性對複數個半導體晶片供給燒結接合用材料之上述之轉印步驟。此種本燒結接合用片材適於在包含半導體晶片燒結接合部位之半導體裝置之製造過程中之燒結製程中實現良好之作業效率。
如上所述,本燒結接合用片材適於作業效率較佳地製作,並且適於在包含半導體晶片燒結接合部位之半導體裝置之製造過程中之燒結製程中實現良好之作業效率。
本燒結接合用片材藉由SAICAS法所測定之100℃下之剪切強度較佳為20 MPa以下,更佳為9 MPa以下,更佳為7 MPa以下。於本燒結接合用片材中,藉由SAICAS法所測定之23℃下之剪切強度(第1剪切強度)如上所述為2~40 MPa,且藉由該方法所測定之100℃下之剪切強度(第2剪切強度)為20 MPa以下之構成就於23~100℃之溫度範圍內確保本燒結接合用片材之良好之剪裁性之方面而言較佳。又,實施半導體裝置製造過程中之上述之轉印步驟之溫度存在包含於70℃及其附近之23~100℃之溫度範圍之情形。第1剪切強度為2~40 MPa且第2剪切強度為20 MPa以下之上述構成適於確保轉印步驟實施溫度即70℃及其附近之溫度範圍內之本燒結接合用片材之良好之剪裁性,因此就使用本燒結接合用片材適當地實施上述之轉印步驟之方面而言較佳。
本燒結接合用片材之黏合劑成分較佳為包含高分子黏合劑及/或低分子黏合劑。此種構成就於燒結接合用片材中調整其彈性模數或黏著力等各種物性之方面而言較佳。

本燒結接合用片材中之熱分解性高分子黏合劑等高分子黏合劑之重量平均分子量較佳為10000以上。此種構成就利用熱分解性高分子黏合劑等高分子黏合劑之黏彈性來確保本燒結接合用片材或來自其之燒結接合用材料層之凝聚力或接著力之方面而言較佳。
本燒結接合用片材中之熱分解性高分子黏合劑等高分子黏合劑較佳為包含聚碳酸酯樹脂及/或丙烯酸系樹脂。如上所述,於使用本燒結接合用片材來實現燒結接合之過程中,利用來自本燒結接合用片材之燒結接合用材料層將接合對象物間暫時固定後進行燒結接合用之高溫加熱。燒結接合用之高溫加熱例如於包含300℃及其附近之溫度範圍內進行,結果聚碳酸酯樹脂及丙烯酸系樹脂作為於300℃左右之溫度下會分解、揮散之高分子黏合劑而容易準備。因此,本構成就於使用本燒結接合用片材進行燒結接合之接合對象物間所形成之燒結層中降低有機殘渣之方面而言較佳。存在燒結層中之有機殘渣越少則該燒結層越牢固之傾向,因此於該燒結層中容易獲得較高之接合可靠性。
本燒結接合用片材中之低分子黏合劑較佳為包含沸點低於熱分解性高分子黏合劑之熱分解開始溫度之低沸點黏合劑。此種構成適於在本燒結接合用片材中確保良好之黏性,因此適於確保對半導體晶片或基材等其他構件之良好密接性。
本燒結接合用片材中之高分子黏合劑與低分子黏合劑之比率(高分子黏合劑/低分子黏合劑)例如為3以下,較佳為2.5以下,更佳為2.0以下,進而較佳為1.5以下。此種構成就將本燒結接合用片材之藉由SAICAS法所測定之23℃下之剪切強度調整為特定之範圍之方面而言較佳。

圖2至圖6係表示使用上述之片材體X或燒結接合用片材10所進行之半導體裝置製造方法之一部分之步驟。本方法係用以製造具備半導體晶片之燒結接合部位之功率半導體裝置等半導體裝置之方法。
於本方法中,首先,如圖2(a)所示,準備具有燒結接合用片材10之上述片材體X及複數個晶片C。複數個晶片C各自為已經嵌入有特定半導體元件之半導體晶片。複數個晶片C於加工用膠帶T1之黏著面T1a上以鄰接晶片間留有空隙之方式排列。作為用以形成晶片C之晶片本體之構成材料,例如可列舉碳化矽(SiC)或氮化鎵(GaN)等功率半導體裝置用之半導體材料。晶片C之厚度例如為20~1000 μm。於各晶片C中,供貼附燒結接合用片材10之側之表面(圖2中為圖中上表面)已經形成有外部電極(圖示省略)。外部電極例如為銀平面電極,其厚度例如為10 nm~1000 nm。作為外部電極之銀平面電極亦可積層形成於半導體晶片表面上所形成之鈦薄膜上。該鈦薄膜之厚度例如為10 nm~1000 nm。該等銀平面電極及鈦薄膜例如可藉由蒸鍍法形成。又,於各晶片C之另一面(圖2中為圖中下表面)視需要形成有其他外部電極(圖示省略)。
於本半導體裝置製造方法中,繼而進行轉印步驟。於轉印步驟中,首先,如圖2(b)所示,對加工用膠帶T1上之複數個晶片C壓接片材體X之燒結接合用片材10之側來進行貼合。作為用以貼合之按壓機構,例如可列舉壓接輥。貼合溫度例如處於室溫至200℃之範圍,較佳為65~75℃。用以貼合之荷重例如為0.01~10 MPa。貼合之後,如圖2(c)所示,一面使燒結接合用片材10之一部分殘留於晶片C側,一面進行基材B之剝離作業。藉由此種貼合作業與其後之剝離作業進行燒結接合用材料自燒結接合用片材10向各晶片C之轉印,而於晶片C上產生作為自周圍分離出之燒結接合用片材小片之燒結接合用材料層11。於本步驟中,可一次性地對各晶片C供給燒結接合用材料。
於本半導體裝置製造方法中,繼而,如圖3所示,將晶片C與燒結接合用片材10中密接於該晶片C之部分一起自加工用膠帶T1拾取,獲得帶有燒結接合用材料層11之晶片C(拾取步驟)。於本實施形態之拾取步驟中,具體而言,於加工用膠帶T1之圖中下側使拾取機構之頂銷構件21上升,介隔加工用膠帶T1將拾取對象之晶片C頂起。於此種頂起之後,藉由對燒結接合用材料層11側之吸附作用,而利用吸附筒夾22吸附保持該晶片C。如此可進行附有燒結接合用材料層11之晶片C之拾取。
於本實施形態中,繼而,如圖4所示,自拾取有附有燒結接合用材料層之晶片C之吸附筒夾22向另一吸附筒夾23交接該晶片C。吸附筒夾23藉由對附有燒結接合用材料層之晶片C之晶片側之吸附作用而保持該晶片C。
繼而,如圖5(a)所示,將附有燒結接合用材料層之晶片C經由其燒結接合用材料層11壓接於支持基板S來暫時固定(暫時固定步驟)。具體而言,例如使用晶片安裝機,將附有燒結接合用材料層之晶片C經由其燒結接合用材料層11按壓於支持基板S來暫時固定。作為支持基板S,例如可列舉表面帶有銅配線等配線之絕緣電路基板、及引線框架。支持基板S中之晶片搭載部位可為銅配線或引線框架等基體表面,亦可為形成於基體表面上之鍍覆膜之表面。作為該鍍覆膜,例如可列舉:鍍金膜、鍍銀膜、鍍鎳膜、鍍鈀膜、及鍍鉑膜。於本步驟中,暫時固定用之溫度條件例如處於室溫至300℃之範圍,按壓之荷重例如為0.01~50 MPa,接合時間例如為0.01~300秒鐘。
繼而,如圖5(b)所示,經過加熱過程而由介存於暫時固定之晶片C與支持基板S之間之燒結接合用材料層11形成燒結層12,從而將晶片C燒結接合於支持基板S(燒結接合步驟)。具體而言,藉由經過特定之高溫加熱過程,於支持基板S與晶片C之間使燒結接合用材料層11中之低分子黏合劑揮發,視需要使高分子黏合劑之全部或一部分進行熱分解而揮散,而且使燒結性粒子之導電性金屬進行燒結。藉此,於支持基板S與晶片C之間形成燒結層12,一面將晶片C接合於支持基板S一面取得與支持基板S側之電性連接。於本步驟中,燒結接合之溫度條件例如處於150~400℃之範圍。用以燒結接合之壓力例如為60 MPa以下。又,燒結接合之接合時間例如為0.3~300分鐘。例如於該等條件之範圍內適當地設定用以實施燒結接合步驟之溫度分佈或壓力分佈。如上之燒結接合步驟可使用能夠同時進行加熱與加壓之裝置來進行。作為此種裝置,例如可列舉覆晶接合機及平行平板壓製機。又,就參與燒結接合之金屬之抗氧化之觀點而言,本步驟較佳為於氮氣氛圍下、減壓下、或還原氣體氛圍下進行。
於本半導體裝置製造方法中,繼而,如圖6(a)所示,將晶片C之電極部(圖示省略)與支持基板S所具有之端子部(圖示省略)視需要經由接合線W進行電性連接(打線接合步驟)。晶片C之電極部或支持基板S之端子部與接合線W之接線例如藉由帶有加熱之超音波熔接來實現。作為接合線W,例如可使用金線、鋁線、或銅線。打線接合中之線加熱溫度例如為80~250℃。又,其加熱時間例如為數秒~數分鐘。
繼而,如圖6(b)所示,形成用以保護支持基板S上之晶片C或接合線W之密封樹脂R(密封步驟)。於本步驟中,例如藉由使用模具所進行之轉注成形技術而形成密封樹脂R。作為密封樹脂R之構成材料,例如可使用環氧系樹脂。於本步驟中,用以形成密封樹脂R之加熱溫度例如為165~185℃,加熱時間例如為60秒~數分鐘。於在本密封步驟中密封樹脂R之硬化未充分進行之情形時,於本步驟之後進行用以使密封樹脂R完全硬化之後硬化步驟。
如此可製造具備半導體晶片之燒結接合部位之半導體裝置。
如上所述,片材體X中之燒結接合用片材10藉由SAICAS法所測定之23℃下之剪切強度(第1剪切強度)為2~40 MPa。關於包含含有導電性金屬之燒結性粒子與黏合劑成分之組合物之片材體,本發明者等人得出以下見解:藉由上述條件下之SAICAS法所測定之23℃下之剪切強度為2~40 MPa之構成適於保持其片材形狀且獲得良好之剪裁性。例如,如下述之實施例及比較例所示。於燒結接合用片材10中,藉由上述條件下之SAICAS法所測定之23℃下之剪切強度為2 MPa以上之構成就以保持片材形狀之材料之形式操作燒結接合用片材10之方面而言較佳。於燒結接合用片材10中,藉由上述條件下之SAICAS法所測定之23℃下之剪切強度為40 MPa以下之構成就燒結接合用片材10不會變得過硬而發揮良好之剪裁性之方面而言較佳。關於燒結接合用片材10,就其良好之剪裁性之觀點而言,藉由SAICAS法所測定之23℃下之剪切強度較佳為2~35 MPa,更佳為2~32 MPa。並且,適於獲得良好之剪裁性之燒結接合用片材10適於在其製作製程中適當地實施切斷或沖裁加工,因此適於作業效率較佳地製作。並且,適於獲得良好之剪裁性之燒結接合用片材10適於在半導體裝置製造過程中之上述之轉印步驟中,使作為自周圍分離之燒結接合用片材10小片之燒結接合用材料層11產生於半導體晶片上。即,燒結接合用片材10適於適當地實施一次性對複數個半導體晶片供給燒結接合用材料之上述之轉印步驟。此種燒結接合用片材10適於在包含半導體晶片燒結接合部位之半導體裝置之製造過程中之燒結製程中實現良好之作業效率。
如上所述,燒結接合用片材10適於作業效率較佳地製作,並且適於在包含半導體晶片燒結接合部位之半導體裝置之製造過程中之燒結製程中實現良好之作業效率。
如上所述,片材體X中之燒結接合用片材10藉由SAICAS法所測定之100℃下之剪切強度(第2剪切強度)較佳為20 MPa以下,更佳為9 MPa以下,更佳為7 MPa以下。於燒結接合用片材10中,藉由SAICAS法所測定之23℃下之剪切強度(第1剪切強度)如上所述為2~40 MPa,且藉由該方法所測定之100℃下之剪切強度(第2剪切強度)為20 MPa以下之構成就於23~100℃之溫度範圍內確保燒結接合用片材10之良好之剪裁性之方面而言較佳。又,實施半導體裝置製造過程中之上述之轉印步驟之溫度存在包含於70℃及其附近之23~100℃之溫度範圍之情形。第1剪切強度為2~40 MPa且第2剪切強度為20 MPa以下之上述構成適於確保例如70℃及其附近之轉印步驟實施溫度下之燒結接合用片材10之良好剪裁性,因此就使用燒結接合用片材10適當地實施上述之轉印步驟之方面而言較佳。
如上所述,燒結接合用片材10之黏合劑成分較佳為包含熱分解性高分子黏合劑。根據此種構成,容易於上述暫時固定之溫度、例如70℃及其附近之溫度範圍內,利用熱分解性高分子黏合劑之黏彈性來確保燒結接合用片材10或來自其之燒結接合用材料層11之凝聚力,因此容易確保燒結接合用片材10或燒結接合用材料層11之接著力。因此,本構成就如下方面而言較佳,即抑制於在接合對象物間介存有來自燒結接合用片材10之燒結接合用材料層11之狀態下將接合對象物彼此壓接時或壓接後該等接合對象物產生錯位。
如上所述,燒結接合用片材10中之熱分解性高分子黏合劑等高分子黏合劑之重量平均分子量較佳為10000以上。此種構成就利用高分子黏合劑之黏彈性來確保燒結接合用片材10或來自其之燒結接合用材料層11之凝聚力或接著力之方面而言較佳。

如上所述,燒結接合用片材10中之低分子黏合劑包含沸點低於高分子黏合劑之熱分解開始溫度之低沸點黏合劑。此種構成適於在燒結接合用片材10中確保良好之黏性,因此適於確保對晶片C或基材B等其他構件之良好之密接性。因此,本構成就如下方面而言較佳,即抑制在接合對象物間介存有來自燒結接合用片材10之燒結接合用材料層11之狀態下將接合對象物彼此壓接時或壓接後該等接合對象物產生錯位。
