Description
図1で示されるように、ダイシングテープ一体型半導体裏面用フィルム1は、基材31上に粘着剤層32が設けられたダイシングテープ3と、前記粘着剤層上に設けられたフリップチップ型半導体裏面用フィルム(以下、「半導体裏面用フィルム」という場合がある)2とを備える構成である。また、本発明のダイシングテープ一体型半導体裏面用フィルムは、図1で示されているように、ダイシングテープ3の粘着剤層32上において、半導体ウエハの貼着部分に対応する部分33のみに半導体裏面用フィルム2が形成された構成であってもよいが、粘着剤層32の全面に半導体裏面用フィルムが形成された構成でもよく、また、半導体ウエハの貼着部分に対応する部分33より大きく且つ粘着剤層32の全面よりも小さい部分に半導体裏面用フィルムが形成された構成でもよい。なお、半導体裏面用フィルム2の表面(ウエハの裏面に貼着される側の表面)は、ウエハ裏面に貼着されるまでの間、セパレータ等により保護されていてもよい。
半導体裏面用フィルム2はフィルム状の形態を有している。半導体裏面用フィルム2は、通常、製品としてのダイシングテープ一体型半導体裏面用フィルムの形態では、未硬化状態(半硬化状態を含む)であり、ダイシングテープ一体型半導体裏面用フィルムを半導体ウエハに貼着させた後に熱硬化される(詳細については後述する)。
<ゲル分率の測定方法>
半導体裏面用フィルムから約0.1gをサンプリングして精秤し(試料の重量)、該サンプルをメッシュ状シートで包んだ後、約50mlのトルエン中に室温で1週間浸漬させる。その後、溶剤不溶分(メッシュ状シートの内容物)をトルエンから取り出し、130℃で約2時間乾燥させ、乾燥後の溶剤不溶分を秤量し(浸漬・乾燥後の重量)、下記式(a)よりゲル分率(重量%)を算出する。
ゲル分率(重量%)=[(浸漬・乾燥後の重量)/(試料の重量)]×100 (a)
前記ダイシングテープ3は、基材31上に粘着剤層32が形成されて構成されている。このように、ダイシングテープ3は、基材31と、粘着剤層32とが積層された構成を有していればよい。基材(支持基材)は粘着剤層等の支持母体として用いることができる。前記基材31は放射線透過性を有していることが好ましい。前記基材31としては、例えば、紙などの紙系基材;布、不織布、フェルト、ネットなどの繊維系基材;金属箔、金属板などの金属系基材;プラスチックのフィルムやシートなどのプラスチック系基材;ゴムシートなどのゴム系基材;発泡シートなどの発泡体や、これらの積層体[特に、プラスチック系基材と他の基材との積層体や、プラスチックフィルム(又はシート)同士の積層体など]等の適宜な薄葉体を用いることができる。本発明では、基材としては、プラスチックのフィルムやシートなどのプラスチック系基材を好適に用いることができる。このようなプラスチック材における素材としては、例えば、ポリエチレン(PE)、ポリプロピレン(PP)、エチレン−プロピレン共重合体等のオレフィン系樹脂;エチレン−酢酸ビニル共重合体(EVA)、アイオノマー樹脂、エチレン−(メタ)アクリル酸共重合体、エチレン−(メタ)アクリル酸エステル(ランダム、交互)共重合体等のエチレンをモノマー成分とする共重合体;ポリエチレンテレフタレート(PET)、ポリエチレンナフタレート(PEN)、ポリブチレンテレフタレート(PBT)等のポリエステル;アクリル系樹脂;ポリ塩化ビニル(PVC);ポリウレタン;ポリカーボネート;ポリフェニレンスルフィド(PPS);ポリアミド(ナイロン)、全芳香族ポリアミド(アラミド)等のアミド系樹脂;ポリエーテルエーテルケトン(PEEK);ポリイミド;ポリエーテルイミド;ポリ塩化ビニリデン;ABS(アクリロニトリル−ブタジエン−スチレン共重合体);セルロース系樹脂;シリコーン樹脂;フッ素樹脂などが挙げられる。
本実施の形態に係るダイシングテープ一体型半導体裏面用フィルムの製造方法について、図1に示すダイシングテープ一体型半導体裏面用フィルム1を例にして説明する。先ず、基材31は、従来公知の製膜方法により製膜することができる。当該製膜方法としては、例えばカレンダー製膜法、有機溶媒中でのキャスティング法、密閉系でのインフレーション押出法、Tダイ押出法、共押出し法、ドライラミネート法等が例示できる。
半導体ウエハとしては、公知乃至慣用の半導体ウエハであれば特に制限されず、各種素材の半導体ウエハから適宜選択して用いることができる。本発明では、半導体ウエハとしては、シリコンウエハを好適に用いることができる。
本実施の形態に係る半導体装置の製造方法について、図2を参照しながら以下に説明する。図2は、前記ダイシングテープ一体型半導体裏面用フィルム1を用いた場合の半導体装置の製造方法を示す断面模式図である。
先ず、図2(a)で示されるように、ダイシングテープ一体型半導体裏面用フィルム1の半導体裏面用フィルム2上に任意に設けられたセパレータを適宜に剥離し、当該半導体裏面用フィルム2上に半導体ウエハ4を貼着して、これを接着保持させ固定する(マウント工程)。このとき前記半導体裏面用フィルム2は未硬化状態(半硬化状態を含む)にある。また、ダイシングテープ一体型半導体裏面用フィルム1は、半導体ウエハ4の裏面に貼着される。半導体ウエハ4の裏面とは、回路面とは反対側の面(非回路面、非電極形成面などとも称される)を意味する。貼着方法は特に限定されないが、圧着による方法が好ましい。圧着は、通常、圧着ロール等の押圧手段により押圧しながら行われる。
次に、図2(b)で示されるように、半導体ウエハ4のダイシングを行う。これにより、半導体ウエハ4を所定のサイズに切断して個片化(小片化)し、半導体チップ5を製造する。ダイシングは、例えば、半導体ウエハ4の回路面側から常法に従い行われる。また、本工程では、例えば、ダイシングテープ一体型半導体裏面用フィルム1まで切込みを行うフルカットと呼ばれる切断方式等を採用できる。本工程で用いるダイシング装置としては特に限定されず、従来公知のものを用いることができる。また、半導体ウエハ4は、半導体裏面用フィルムを有するダイシングテープ一体型半導体裏面用フィルム1により優れた密着性で接着固定されているので、チップ欠けやチップ飛びを抑制できると共に、半導体ウエハ4の破損も抑制できる。なお、半導体裏面用フィルム2がエポキシ樹脂を含む樹脂組成物により形成されていると、ダイシングにより切断されても、その切断面において半導体裏面用フィルムの接着剤層の糊はみ出しが生じるのを抑制又は防止することができる。その結果、切断面同士が再付着(ブロッキング)することを抑制又は防止することができ、後述のピックアップを一層良好に行うことができる。
ダイシングテープ一体型半導体裏面用フィルム1に接着固定された半導体チップ5を回収する為に、図2(c)で示されるように、半導体チップ5のピックアップを行って、半導体チップ5を半導体裏面用フィルム2とともにダイシングテープ3より剥離させる。ピックアップの方法としては特に限定されず、従来公知の種々の方法を採用できる。例えば、個々の半導体チップ5をダイシングテープ一体型半導体裏面用フィルム1の基材31側からニードルによって突き上げ、突き上げられた半導体チップ5をピックアップ装置によってピックアップする方法等が挙げられる。なお、ピックアップされた半導体チップ5は、その裏面が半導体裏面用フィルム2により保護されている。
ピックアップした半導体チップ5は、図2(d)で示されるように、基板等の被着体に、フリップチップボンディング方式(フリップチップ実装方式)により固定させる。具体的には、半導体チップ5を、半導体チップ5の回路面(表面、回路パターン形成面、電極形成面などとも称される)が被着体6と対向する形態で、被着体6に常法に従い固定させる。例えば、半導体チップ5の回路面側に形成されているバンプ51を、被着体6の接続パッドに被着された接合用の導電材(半田など)61に接触させて押圧しながら導電材を溶融させることにより、半導体チップ5と被着体6との電気的導通を確保し、半導体チップ5を被着体6に固定させることができる(フリップチップボンディング工程)。このとき、半導体チップ5と被着体6との間には空隙が形成されており、その空隙間距離は、一般的に30μm〜300μm程度である。尚、半導体チップ5を被着体6上にフリップチップボンディング(フリップチップ接続)した後は、半導体チップ5と被着体6との対向面や間隙を洗浄し、該間隙に封止材(封止樹脂など)を充填させて封止することが重要である。

各実施例及び比較例で使用したフィラーの平均粒径及び最大粒径については、レーザー回折式の粒度分布計(HORIBA製、装置名;LA−910)を用いて測定した。結果を下記表1に示す。
各実施例及び比較例で作製したフリップチップ型半導体裏面用フィルムを、乾燥機内において175℃、1時間で熱処理を行い、熱硬化させた。その後、TWA法(温度波熱分析法、測定装置;アイフェイズモバイル、(株)アイフェイズ製)により、各ダイボンドフィルムの熱拡散率α(m2/s)を測定した。次に、各ダイボンドフィルムの比熱Cp(J/g・℃)を、DSC法により測定した。比熱測定は、エスアイアイナノテクノロジー(株)製のDSC6220を用い、昇温速度10℃/min、温度20〜300℃の条件下で行い、得られた実験データを基に、JISハンドブック(比熱容量測定方法K−7123)により算出した。更に、各半導体裏面用フィルムの比重を測定した。
半導体裏面用フィルムA〜Fの露出面側(剥離ライナとは反対側の面)の表面粗さ(Ra)を、JIS B 0601に基づき、Veeco社製の非接触三次元粗さ測定装置(NT3300)を用いて測定した。測定条件は、50倍とし、測定値は、測定データにMedian filterをかけて求めた。測定は、各フリップチップ型半導体裏面用フィルムについて、測定箇所を変更しながら5回行い、その平均値を表面粗さ(Ra)とした。
半導体裏面用フィルムの半導体ウエハに対する接着性(剥離力)は、半導体ウエハとしてのシリコンウエハを熱板の上に置き、所定の温度(50℃)下で、粘着テープ(商品名「BT315」日東電工株式会社製)により裏面補強した長さ150mm、幅10mmの半導体裏面用フィルムを2kgのローラーを一往復して貼り合わせる。その後、熱板上(50℃)に2分間静置した後、常温(23℃程度)で20分静置し、放置後、剥離試験機(商品名「オートグラフAGS−J」島津製作所社製)を用いて、温度23℃の条件下で、剥離角度:180°、引張速度:300mm/minの条件で、裏面補強された半導体裏面用フィルムを引き剥がして(半導体裏面用フィルムと半導体ウエハとの界面で剥離させて)、この引き剥がした時の荷重の最大荷重(測定初期のピークトップを除いた荷重の最大値)を測定し、この最大荷重を半導体裏面用フィルムと半導体ウエハ間の接着性(半導体裏面用フィルムの半導体ウエハに対する接着性)として、半導体裏面用フィルムの剥離力(N/10mm幅)を求める。
前記の<半導体裏面用フィルムの半導体ウエハに対する接着性評価>により得られた半導体裏面用フィルムを半導体ウエハに貼り合わせたサンプルにおける半導体裏面用フィルムの表面に、YAGレーザーによりレーザーマーキングを施し、該レーザーマーキングにより得られた情報(バーコード情報)について、下記の評価基準により、各実施例又は各比較例に係る半導体裏面用フィルムのレーザーマーキング性を評価した。
+:無作為に選んだ成人10人中、レーザーマーキングにより得られた情報を良好に視認できると判断した人数が8人以上である
−:無作為に選んだ成人10人中、レーザーマーキングにより得られた情報を良好に視認できると判断した人数が7人以下である
表1から分かる通り、実施例1及び2のように、熱伝導性フィラーの含有量が50体積%以上であり、かつ熱伝導性フィラーの平均粒径及び最大粒径がそれぞれ前記半導体裏面用フィルムの厚みの30%以下及び80%以下であると、半導体裏面用フィルムの表面粗さを低い値に抑えつつ、良好な熱伝導性が得られた。加えて、半導体裏面用フィルムの半導体ウエハに対する接着性及びレーザーマーキング性も良好な結果となった。一方、比較例1及び2のように、熱伝導性フィラーの含有量が50体積%未満であると熱伝導率が低下してしまった。また、熱伝導性フィラーの平均粒径及び最大粒径がそれぞれ前記半導体裏面用フィルムの厚みの30%及び80%を超えると、熱伝導率は良好であるものの表面粗さが大きくなり、半導体裏面用フィルムの半導体ウエハへの接着性及びレーザーマーキング性が劣る結果となった。
