Description
図9に示す半導体装置に於いて、半導体基板500の一方の主面上に、電極パッド510が一定間隔で形成され、該電極パッド510間にはカバー膜520が形成されている。更に、電極パッド510の一部を含み、カバー膜520の全体を覆うように保護膜530が一定間隔で形成されている。そして、電極パッド510上には、バリアメタル540を介して半田バンプ550が形成されている。なお、バリアメタル540は、電極パッド510と半田バンプ550との密着性を向上させる機能を有する。
このような外部接続端子構成にあっては、バンプピッチの狭小化に伴い、バリアメタル540も微細化することが必要となるが、バリアメタル540の微細化は困難であり、しかも高コスト化を招くこととなる。更に、半田によりバンプを形成すると、リフロー時に、その形状が球形状となることから、バンプピッチの狭小化に対応することが困難となる。なお、従来例で形成可能なバンプに於けるバンプピッチは、170〜220μm程度である。
また、電解めっきによりバンプを形成する方法が知られている。この場合、通常、バンプと配線(パッド)との間には、バリアメタルが形成されている。バリアメタルは、バンプとパッドとの密着性を向上させるほか、電解めっき法によりパッド上にバンプを形成する際の共通電極として機能するという利点がある。しかし、狭ピッチ化に伴って、バリアメタルも微細化することが必要となるが、微細なバリアメタルの製造は困難であり、しかも、半導体装置の1チップ、1パッケージあたりのコストが圧縮される中、バリアメタルを形成するコストが高くなるという問題がある。
例えば、パッドの表面に形成される反射防止膜の材料として、バリアメタルと同一材料を用いることにより、バリアメタルの形成を省略し、電解めっきの際には、前記反射防止膜を共通電極として使用することによりバンプを形成する方法が提案されている(特許文献3参照)。しかし、この方法では、バンプの形成後に余分な配線層が露出しており、該配線層を除去しなければならず、従来のバリアメタルの除去工程と同様な処理が必須となり、製造工程の簡略化の点で、充分とはいえない。
本発明の半導体装置の製造方法は、半導体基板の一方の主面に複数個の電極パッドを形成する工程と、前記電極パッドの周縁部を覆って絶縁層を形成する工程と、前記絶縁層上に選択的にマスク層を形成する工程と、前記絶縁層に覆われない電極パッドの表面を清浄化する工程と、前記絶縁層及び前記マスク層により規定される領域に、前記電極パッドに接して外部接続用端子を形成する工程と、前記マスク層を除去する工程とを少なくとも含むことを特徴とする。
該半導体装置の製造方法では、まず、前記半導体基板の一方の主面に複数個の前記電極パッドが形成される。前記電極パッドの周縁部を覆って前記絶縁層が形成される。前記絶縁層上に選択的に前記マスク層が形成される。前記絶縁層に覆われない電極パッドの表面が清浄化される。前記絶縁層及び前記マスク層により規定される領域に、前記電極パッドに接して前記外部接続用端子が形成される。前記マスク層が除去される。ここで、前記マスク層を除去する工程において、前記電極パッドは一度も露出されることがない。例えば、前記半導体基板上にバリアメタルを形成し、該バリアメタル上にバンプ(外部接続用端子)を形成する場合には、露出した前記バリアメタルの一部を除去することが必要となるが、本発明の前記半導体装置の製造方法においては、前記バリアメタルの形成及び除去のいずれも不要である。このため、狭ピッチで形成された微細なバンプを有する半導体装置が低コストかつ簡便に効率よく製造される。
該半導体装置においては、前記外部接続用端子が前記電極パッドに直接接して配置されており、通常、前記外部接続用端子と前記電極パッドとの間に形成されるバリアメタルを有しない。
本発明の前記半導体装置は、狭ピッチで形成された微小なバンプを有し、高品質かつ高性能である。
本発明の半導体装置の製造方法の第1の実施例について、図面を参照しながら説明する。
まず、所定のウェハプロセスに従って、シリコン(Si)からなる半導体基板(ウェーハ)10の上面(一方の主面)に、複数個の半導体素子(デバイス)を形成する。
次いで、図1Aに示すように、前記半導体素子の外部接続端子部が選択的に表出されるように、該外部接続端子部を構成する電極パッド12の周縁部を覆うように無機絶縁層14を選択的に形成し、更に無機絶縁層14の表面及び側面を覆うように有機絶縁層16を形成する。
また、無機絶縁層14は、二酸化シリコン(SiO2)からなる下地層と窒化シリコン(SiN)からなる上層との積層体からなり、その厚みとしては、300〜800μm程度が選択される。
更に、有機絶縁層16は、ポリイミド樹脂からなり、その厚みとしては、1〜20μm程度が選択される。
なお、このような有機絶縁層16の配設構造によれば、無機絶縁層14と電極パッド12との界面への水分の侵入を防止することができると共に、後述する外部接続用端子(バンプ)に対する機械的ストレスの緩和を図ることができる。
フォトレジスト層20は、以下の工程に於いてマスク層として機能する。このとき、フォトレジスト層20は、電極パッド12を選択的に覆う有機絶縁層16の縁部近傍が表出されるように後退したパターンとされ、フォトレジスト層20は、電極パッド12及び有機絶縁層16の一部を表出して配設される。即ち、図2Aに示すように、フォトレジスト層20が除去された状態を想定した場合、電極パッド12上に形成される外部接続用端子(バンプ)Mbが、有機絶縁層16により規定される開口寸法Aよりも大きく有機絶縁層16上に寸法Bにまで延在する形態(A<B)となるように、また、図2Bに示すように、フォトレジスト層20に設けられる開口寸法Cは、開口寸法Aよりも大きく(A<C)設定される。
なお、フォトレジスト層20を構成するフォトレジスト材料は、ポジ型、ネガ型の何れであってもよく、また必要とされるパターン精度に対応して、例えばg線、i線或いはKrF等必要とされる感光波長に対応して選択される。更に、その形態も塗布型或いはフィルム(シート)状の何れであってもよい。また、フォトレジスト層20の厚さとしては、150μm程度が選択される。
バンプ形成用装置700は、半導体ウェーハ10に形成されている半導体素子に於ける、各電極パッド12の露出表面に存在する酸化被膜の除去を行う第1の処理チャンバ71、フォトレジスト層20により画定された領域内にバンプ形成用金属材料含むペーストを充填する第2の処理チャンバ72、及び該ペーストを加熱処理する第3の処理チャンバ73を具備している。
また、これらのチャンバ間、或いは該チャンバとウェーハセットチャンバ74との間に於ける被処理半導体ウェーハ10の移動は、ウェーハ搬送チャンバ75に於ける搬送用アーム(図示せず)により行われる。更に、バンプ形成用装置700内は、真空或いは減圧状態に維持され、また各チャンバ内はそれぞれ適切な真空或いは減圧状態が設定される。
その後、ウェーハセットチャンバ74に収容されている被処理半導体ウェーハ10を、搬送用アームにより第1の処理チャンバ(酸化膜除去チャンバ)71へ搬送する。該第1の処理チャンバ71内に於いて、半導体ウェーハ10に形成されている複数個の半導体素子に於ける、電極パッド12の露出表面にある酸化被膜の除去を行う。即ち、図4Aに示すように、有機絶縁膜16により画定された開口18内に表出する電極パッド12の表面に存在する酸化被膜42を除去し、電極パッド12の金属層表面を表出させる。
ここで、酸化被膜42の除去は、CHF3とO2との混合ガス、CHF4とO2との混合ガス、O2ガス、或いはN2ガスを用いた浄化処理により行うことができる。処理温度としては、20〜200℃が好ましく、出力としては、0.5〜2.0kWが好ましい。
酸化被膜42の除去は、アルゴン(Ar)ガス又は窒素(N2)ガスを用いたRFスパッタリッグ法、或いは蟻酸ガスを用いた還元処理によっても行うことができる。
前記RFスパッタリッグ法を用いる場合、処理温度は50〜200℃、RF出力は0.5〜2.0kWが好ましい。また、蟻酸ガスを用いた還元処理の場合、処理温度は20〜200℃が好ましい。
そして、第2の処理チャンバ72内に於いて、半導体ウェーハ10に形成されている各半導体素子の電極パッド12の露出部を対象に、フォトレジスト層20により画定された領域内に、金属材料含むペーストの充填処理がなされる。即ち、真空或いは減圧状態に於いて、フォトレジスト層20により画定された領域内に、フォトレジスト層20と同等の高さとなるよう、金属粒子(粉末)を含有する樹脂からなる導電性ペースト44が充填される。かかる状態を図4Bに示す。
なお、かかる導電性ペースト44の充填の際、第2の処理チャンバ72内は、真空或いは減圧状態に維持されていることから、電極パッド12上の有機絶縁層16より画定された開口18内に空気などが取り込まれることは無い。従って、気泡(ボイド)を含むことなく導電性ペースト44を充填することができる。
また、前記樹脂としては熱硬化性樹脂が適用されるが、適用される金属の融点よりも低い温度にて硬化することを要する。このため、該金属が銅(Cu:融点1,083℃)である場合には、エポキシ樹脂が適用される。
前記樹脂としては、熱硬化性樹脂に代えて、光硬化性樹脂を適用することもできる。
前記金属粒子(粉末)の含有量としては、特に制限はなく、目的に応じて適宜選択することができ、例えば、前記樹脂に対する重量比で、金属95:樹脂5〜金属70:樹脂30が好ましい。
そして、第3の処理チャンバ73内にて、真空或いは減圧状態に於いて、半導体ウェーハ10に対し加熱処理を行い、導電性ペースト44を硬化させて、外部接続用端子(バンプ)46を形成する。かかる状態を、図4Cに示す。
なお、導電性ペースト44の加熱処理の際、第3の処理チャンバ73内は、真空或いは減圧状態に維持されていることから、導電性ペースト44からガスが放出されたとしても、当該ガスが外部接続用端子(バンプ)46内に取り込まれることは無い。
本工程に於ける加熱温度は、導電性ペースト44を構成する樹脂材料及び該樹脂材料中に含有される金属材料に対応して選択される。導電性ペースト44が、前述の如く銅粒子を含むエポキシ樹脂である場合には、200℃程度の加熱がなされる。
ウェーハセットチャンバ74内を常圧とした後、被処理半導体ウェーハ10をウェーハセットチャンバ74から取り出し、半導体ウェーハ10上に在るフォトレジスト層20を、アルカリ系溶剤等のエッチャントを用いて溶融除去或いは剥離除去する。これにより、半導体ウェーハ10上には、上面がほぼ平坦な外部接続用端子(バンプ)46が、複数個互いに分離して形成される。かかる状態を、図5に示す。
これに対し、本発明により形成される半導体装置に於ける外部接続用端子(バンプ)46の表面は、下地となる電極パッド12の表面とほぼ並行な平面を有する。従って、通常の球状バンプに比してその高さ(厚さ)を低く抑えることができ、半導体装置の小型化及び薄形化を図ることができる。
なお、本実施例に於ける半導体装置に於ける外部接続用端子(バンプ)46の高さ(厚さ)は、前述の如くフォトレジスト層20の厚さと同等のものとされたが、当該フォドレジスト層の厚さと同等とする必要性は必ずしも無く、該フォトレジスト層の厚さ(高さ)の2/3以上であればよい。
なお、本発明の半導体装置は、以下の実施例のように、種々の変形が可能である。
本発明の半導体装置の第2の実施例を、図6に示す。
図6に示す半導体装置200にあっては、有機絶縁層16が、下層の無機絶縁層14の端部側面を覆うことなく、無機絶縁層14上に配設されている。即ち、有機絶縁層16及び無機絶縁層14が同一のパターンを有して形成されている。
かかる構造によれば、電極パッド12の表出部を規定するこれらの絶縁層(有機絶縁層16及び無機絶縁層14)の加工が容易であり、開口部の開口寸法をより小径化することができる。
そして、外部接続用端子(バンプ)46は、所謂バリア層を介することなく電極パッド12に接し、且つ一部が無機絶縁層14上に延在して配設されている。
かかる構成にあっても、バリアメタルの形成が不要であるので、狭ピッチで微細な外部接続用端子(バンプ)を、低コストで形成することができる。
本発明の半導体装置の第3の実施例を、図7に示す。
図7に示す半導体装置300にあっては、有機絶縁層16が、下層の無機絶縁層14の端部側面を覆うことなく、且つその端部が外部接続用端子(バンプ)の外周側面に接して、無機絶縁層14上に配設されている。
かかる構造によれば、有機絶縁層16の加工精度の緩和が可能である一方、無機絶縁層14についてはより高い精度をもっての加工が可能となり、開口部の開口寸法のより小径化が可能となる。
そして、外部接続用端子(バンプ)46は、所謂バリア層を介することなく電極パッドに接し、且つ一部が無機絶縁層14上に延在して配設される。
かかる構成にあっても、バリアメタルの形成が不要であるので、狭ピッチで微細な外部接続用端子(バンプ)を、低コストで形成することができる。
本発明の半導体装置の第4の実施例を、図8に示す。
図8に示す半導体装置400にあっては、無機絶縁層14の端部側面を覆うことなく、且つ外部接続用端子(バンプ)46から離間して、無機絶縁層14上に、保護被膜16Aが選択的に配設されている。
保護皮膜16Aは、外部接続用端子(バンプ)46から離間して配設されていることから、絶縁性が低い被膜であってもかまわない。
無機絶縁層14は、製造工程中等に於いてその表面に炭素が含まれ、絶縁性が低下する為、その炭素含有部を除去する工程が必要とされるが、本実施例の如く外部接続用端子(バンプ)46から離間して配設されることにより、かかる炭素含有部の除去工程を必要としない。また、かかる構造によれば、無機絶縁層14についてはより高い精度をもっての加工が可能となり、開口部の開口寸法のより小径化が容易となる。
そして、外部接続用端子(バンプ)46は、所謂バリア層を介することなく電極パッド12に接し、且つ一部が無機絶縁層上に延在して配設されている。
かかる構成あっても、バリアメタルの形成が不要であるので、狭ピッチで微細な外部接続用端子(バンプ)を、低コストで形成することができる。
また、外部接続用端子(バンプ)46は無機絶縁層14上に配設される為、前記実施例1に比して、有機絶縁層16の厚さに相当する高さ分、その高さを低くすることができ、より小型の半導体装置を製造することができる。
