具體而言,係以壓合部6之溫度成為loot程度的方 式來控制熱壓合頭4之加熱器,並以異向導電性接著薄膜 7之黏結樹脂7a溫度成為遷合部6之溫度2〇〇艺程度的方 式來控制基台2之加熱器3。 藉此,進行熱壓合之際,可將異向導電性接著薄膜7 以炼融黏度成為UxlG2mPa· s〜1Qxl()5mPa· s的方式來 加熱。 此處,當異向導電性接著薄膜7之熔融黏度未滿1〇χ 102mPa· s的情況,熱壓合時之黏結樹脂7a的流動性大,n 會發生空孔造成初期電阻以及連接可靠度變差,當熔融黏 度超過l.〇xl〇5mPa· s的情況,於熱壓合時在連接部分無 法將黏結樹脂7a完全排除,會發生空孔造成初期電阻以 及連接可靠度變差。 又,正式壓合時之壓力係對於每一個1C晶片以100N 之程度進行15秒左右。 40 〜80 如圖2所示般,本實施形態中,利用橡膠硬度 11 1296905 之彈性體所構成之壓合部6來進行加壓,藉此,可使得ic 晶片20之頂部2〇b相對於配線基板10以既定壓力來抵壓, 另一方面,將IC晶片20之側部的條帶部7c以較頂部2〇b 之壓力來得小之壓力來抵壓,是以,不僅可對於IC晶片2 0 與配線基板1〇之連接部分施加充分的壓力,且對於IC晶 片20周圍之條帶部7c也能以不致發生空孔的方式來加 壓。 其結果,依據本實施形態,可使用異向導電性接著薄 膜7進行高可靠度之ic晶片20等之連接。 特別是,在本實施形態中,進行熱壓合之際,藉由將 K晶片20侧以既定溫度來加熱,且將配線基板1〇側以較 該既定溫度為高之溫度來加熱,則對於IC晶片2〇周圍之 條帶部7c可充分地加熱,可確實防止空孔的發生。 再者,於熱壓合之際,由於將異向導電性接著薄膜7 以熔融黏度成為1〇xl〇2mpa.s〜1〇xl〇5mPa.s的方式來 加熱,乃可更確實地防止熱壓合時在連接部分之黏結樹脂 7a之排除與空孔的發生,可進行可靠度更高之連接。 另一方面,依據本實施形態之構裝裝置1,可得到可 進行高可靠度連接之簡潔構成的構裝裝置。 特別是,依據本實施形態,由於壓合部6之厚度係ic 晶片20厚度之同等以上,乃可對於IC晶片2〇之頂部 與側部之條帶部7c確實地以最適當壓力進行加壓。 圖3係顯示本發明之其他實施形態之概略構成圖,以 下針對與上述實施形態相對應之部分係賦予同一符號而 12 1296905 省略其詳細說明。 ‘ 如圖3所示般,本實施形態之構裝裝置1 a,壓合部6 -
之大小係較配置了複數(例如2個)之例如厚度相異之IC 曰曰片2 0、21的區域面積來得大,此點係與上述實施形熊 不同。 此時,壓合部6本身之橡膠硬度係40〜80,此與上述 實施形態相同。 依據具有此種構成之本實施形態,可將複數之特別是 厚度相異之1C晶片20、21同時以高可靠度做連接,藉此 · 可大幅提昇構裝效率。其他構成與作用效果係與上述實施 形態相同,故在此省略其詳細說明。 又’本發明並不限定於上述實施形態,可進行各種的 變更。 例如,在上述實施形態中,係舉出使用異向導電性接 著薄膜來構裝1C晶片的情況為例來說明,為本發明並不 限定於此,亦可使用不含導電粒子之接著劑。 又,於上述實施形態中,係舉出對於具有凸塊電極之 · 1C晶片進行構裝之情況為例做說明’惟本發明亦可適用於 不具凸塊電極之1C晶片。 (實施例) 以下以實施例與比較例來詳細地說明本發明。 〈實施例1> 在配線基板方面’係使用於玻璃環氧基板上形成寬度 75//m、間距150/zm之銅(Cu)圖案,且其上施以鎳—金锻 13 1296905 係準備形成有150# m間 〇· 4mm之晶片。 敷之硬性基板’在ic晶片方面, 距之凸塊電極的大小6x6mm、厚度 接著’使用熱壓合頭(裝設有由大小6〇x6〇mm、厚度 1〇_、橡膠硬度40之㈣橡膠所構成之壓合部),在異向 導電性接著薄膜方面,係使用於溶融黏度i Qxi()5mPa· g 之黏結樹脂中分散著導電粒子者,將IC日日日片熱壓合於配 線基板上。 此時’以壓合部之溫度為1〇〇。。、異向導電性接著薄 膜之溫度為200 °C的方式來控制基台溫度,以壓力 l〇〇N/IC(278N/cm2)進行15秒鐘之加壓與加熱。 〈實施例2> 除了使用橡膠硬度80之矽酮橡膠所構成之壓合部以 外,其餘與實施例1同樣條件來進行熱壓合。 〈比較例1 > 除了使用橡膠硬度1 〇以下之矽酮橡膠所構成之壓合部 以外’其餘與實施例1同樣條件來進行熱壓合。 〈比較例2> 除了使用橡膠硬度120之矽酮橡膠所構成之壓合部以 外’其餘與實施例1同樣條件來進行熱壓合。 〈實施例3> 除了使用在熔融黏度1 · 〇X1 〇5mpa · s之黏結樹脂中分 散有導電粒子之異向導電性接著薄膜以外,其餘與實施例 1同樣條件來進行熱壓合。 〈比較例3> 1296905 …除了使用在熔融黏度5mPa · s之黏結樹脂中分散有導 電粒子之異向$電性接著薄膜以外,其餘與實施例1同樣 條件來進行熱壓合。 〈比較例4> 除了使用在溶融黏度1.0xl09mPa· s之黏結樹脂中分 政有導電粒子之異向導電性接著薄膜以外,其餘與實施例 1同樣條件來進行熱壓合。 〈比較例5>
