Abstract
【解決手段】パッド電極14の一部が露出する開口部が形成されたパッシベーション層20と、パッド電極14上及びパッシベーション層20上に形成された下地金属層22と、下地金属層に形成され、外部接続用電極に対するバリア金属層26とを有する電子部品において、下地金属層22は開口部の外側又は/及び内側のバリア金属層26の下方に凹部21a又は/及び凸部21b、21cを有する。この凹部又は/及び凸部は開口部の外周囲又は/及び内周囲の全域に亘って形成されている。パッシベーション層20は、高密度プラズマ法によって形成されたSiO2膜を少なくとも1層含む。
【選択図】図1
Description
半導体基板211上にCVD法により酸化膜212を形成した後、LCDドライバICなどの半導体装置を形成する。スパッタ法などによりAlを全面に形成し、フォトリソ・エッチングによりAlをパターニングして、バンプ電極を形成すべき位置に、例えば、50μm×70μm程度の大きさのAl電極パッド213を形成する。CVD法によりSiO2などの絶縁膜を全面に、例えば、0.8〜1.4μm程度の膜厚で、表面保護膜214を形成した後、フォトリソ・エッチングによりAl電極パッド213上の表面保護膜214を除去して、そのAl電極パッド213上にスルーホール15を開孔する。
半導体基板211の表面全体にスパッタ法等により、複数の下地金属層を順次積層形成する。この下地金属層の構成としては、例えば、Alと密着性のよいTi/W216a、Auの拡散を防止するためのPd216bにより構成する。
下地金属層Ti/W216a、Pd216b上にポジ形の感光性樹脂膜を全面に25〜30μm程度の膜厚に被着した後、マスクを用いて、Al電極パッド213上の一部の感光性樹脂膜を露光し、感光性樹脂膜エッチング溶剤に浸して、露光した部位をエッチング(現像)し、Al電極パッド213よりも20μm程度内側のこのAl電極パッド213の上方に、30μm×50μm程度の欠損部を有するバンプ電極形成用パターン217を形成する。次に、下地金属層Ti/W216a、Pd216bを一方の陰極の共通電極として、半導体基板211をシアン化金カリウムまたは亜硫酸金ナトリウムなどのメッキ溶液に浸して、例えば、1A/cm2程度の一定の電流を供給することにより、Auメッキで、例えば、高さが15〜20μm程度のバンプ電極218を形成する。
マスクを用いてバンプ電極形成用パターン217の欠損部の周辺の感光性樹脂膜を、例えば、5μm程度露光し、感光性樹脂膜エッチング溶剤に浸して、露光した部位をエッチングして、そのバンプ電極形成用パターン217よりも各寸法が5μm程度大きい下地金属保護層形成用パターン217aを形成する。
再度、下地金属層Ti/W216a、Pd216bを一方の陰極の共通電極として、半導体基板211をメッキ溶液に浸して、一定の電流(例えば、1A/cm2)を供給することにより、Auメッキで、バンプ電極218の周囲の隙間に、1μm以下の膜厚(この膜圧は、下地金属層Ti/W216a、Pd216bの膜厚により決定する)の下地金属保護層219を形成する。この際に、バンプ電極218上にも同僚のAuメッキが施される。
感光性樹脂膜217aを除去溶剤等で除去し、更に、下地金属保護層219をマスクとして、下地金属層Pd216b、Ti/W216aをエッチング溶液に浸して、ウェットエッチング除去した後、下地金属保護層219を必要に応じてエッチング除去することにより最終的なバンプ電極構造が得られる。この時、下地金属層Pd216bは、下地金属保護層219により被覆されているので、下地金属層Pd216b、Ti/W216aのサイドエッチングが行われる部位がバンプ電極218の直下よりも外側となり、このバンプ電極218の下部の下地金属層Pd216bがエッチングされることがなくなる。そして、例えば、テープキャリアのインナーリードとバンプ電極218をインナーリードボンディングして、実装を終了する。
第1の実施の形態では、パッド電極14を囲む環状の障壁30の形成を行い、パッド電極及び障壁の上方にバンプ電極(突起電極)の形成を行う。ここで障壁は、以下の各実施の形態と同様に、下地金属層が連続して続く部分の距離及び面積を延長させるためのものであり、サイドエッチングの発生の影響を抑制するために設けるものである。この障壁の形成の形態は、以下の各実施の形態によって異なり、それぞれ各実施の形態において詳述される。
図3(A)で説明したように、半導体基板10上に形成された絶縁層12上に、パッド電極14と、パッド電極14を囲む外周層(障壁リング30によって形成される。)とが形成される。パッド電極14の径は、バンプ電極28の径よりも小さい。
障壁リング30は、パッド電極14と同じ材質で同じ厚さで形成してもよい。また、障壁リング30は、絶縁性材料で形成することもできる。
図3(B)に示すように、全面に、HDPによってHDP−酸化シリコン16a、更に、この上に窒化シリコン18が形成される。パッシベーション層(表面保護層)20はHDP−酸化シリコン(SiO2)16a及び窒化シリコン18によって形成される。
図3(C)の平面図、Z−Z部の断面図に示すように、エッチングによってパッシベーション層に開口部15aが形成される。この結果、パッド電極14の一部が露出される(開口部15aの径はパッド電極14の径よりも小さい。)。
図3(D)の平面図、Z−Z部の断面図に示すように、スパッタ法等によって下地金属層22(黒く塗りつぶして図示している。)が全面に形成される。パッシベーション層20の凹部21aの内部にも下地金属層22が形成されるので、下地金属層22にも凹部21aが形成され段差を生じることになる。なお、下地金属層22は、パッシベーション層20とよく接合し、上面の金属メッキ層のためのシード層(下地)として形成され、金属メッキ層を形成する際の電極として使用される。また、下地金属層22の不要部分は、後工程でウェットエッチングによって除去される。
フォトレジスト24を全面塗布する。
バンプ電極形成用のパターンを露光する。
図3(E)のZ−Z部の断面図に示すように、現像して、バンプ電極(矢印で示すバンプ電極の径28aをもつ。)28の形成用の開口部15cを、フォトレジスト24に形成する。
図3(F)のZ−Z部の断面図に示すように、開口部15cの内部に露出された下地金属層22上に、バリア金属層26が電解メッキによって形成される。なお、バリア金属層26は、金属材料の拡散防止や相互反応防止のために用いられ、隣接する母材との密着性がよい材料が用いられる。
図3(F)に示すように、バンプ電極28が電解メッキによってバリア金属層26上に形成される。
図4(A)のZ−Z部の断面図に示すように、フォトレジスト24を剥離する。
図4(A)とその部分拡大断面図に示すように、バリア金属層26をマスクとして、バリア金属層26の下部を除き、バリア金属層26の外側にある下地金属層22をウェットエッチングによって除去する。この時、ウェットエッチングによって、バリア金属層26の下方にある下地金属層22も、同時にエッチングされてしまう。この結果、バリア金属層26の下方に存在していた下地金属層22が除去されてしまい、サイドエッチング部分36が生じてしまう。
図4(B)のZ−Z部の断面図に示すように、バンプ電極28に半田フラックスを塗布する。
図4(B)に示すように、リフロー炉で加熱処理しバンプ電極28の組成、形状を均一化させる。
図4(B)に示すように、フラックスを洗浄除去して、バンプ電極28の形成工程が終了する。
第2の実施の形態では、パッド電極14上の内周囲において、パッシベーション層20によって凸状及び凹状の環状の障壁を形成して、パッド電極及び障壁の上方にバンプ電極28の形成を行う。即ち、この凸状及び凹状の環状の障壁は、パッド電極上に開口部の周方向に沿って形成され、バンプ電極の投影(パッド電極が形成された面への投影である。)面の内部となる位置に形成される。
図7(A)の平面図、X−X部の断面図に示すように、第1の実施の形態と同様に、半導体基板10上に形成された絶縁層12上に、パッド電極14(パッド電極14の形状は第1の実施の形態と同じであるが、径はバンプ電極28の径と同じである。)を形成した後に、全面にパッシベーション層20(酸化シリコン16b、窒化シリコン18からなる。)が形成される。酸化シリコン16bを、HDPに比して密度の低いプラズマを用いて形成したCVD−SiO2膜(例えば、TEOS/O2−CVDや、SiH4/N2O−CVD)としたが、第1の実施の形態と同じようにHDP−SiO2としてもよい。
図7(A)に示すように、パッド電極14上のパッシベーション層20に、中央の第1の開口部15a(例えば、円形の開口部15a)とこれを囲むように障壁を形成するために第2の開口部15b(例えば、円環状の開口部15b)を同時に形成する。第1の開口部15aの径、第2の開口部15bの外径はパッド電極14の径よりも小さい。
従って、本実施の形態では、下地金属層22の不要部分をウェットエッチングで除去する際に、サイドエッチング部分36が生じても、バリア金属層26の下部に、サイドエッチングされることなく残る下地金属層22の面積が、第1の実施の形態、従来技術よりも大きくなり、バリア金属層26と下地金属層22との接合面積を、第1の実施の形態、従来技術よりも更に大きく確保して、バンプ電極28と半導体基板10との接合強度を保持することができ、信頼性をより向上させることができる。
第3の実施の形態では、パッド電極14の一部を露出させる開口部15aの外側でパッド電極14の周縁の上方にあるパッシベーション層20上に、開口部15aの周方向に沿ってリング状の凸状の障壁34を形成して、パッド電極及び障壁34の上方にバンプ電極の形成を行う。即ち、開口部の外周囲に環状の凸部が形成され、この環状の凸部は、パッド電極の内周囲の領域のパッシベーション層上に形成される。この環状の障壁34は、開口部15aの外側のパッシベーション層20上に形成され、バンプ電極の投影(パッド電極が形成された面への投影である。)面の内部となる位置に形成され、バンプ電極とパッシベーション層との間に形成される。
図10(A)の平面図、Y−Y部の断面図に示すように、第1の実施の形態と同様に、半導体基板10上に形成された絶縁層12上に、パッド電極14(パッド電極14の形状は第1の実施の形態と同じであるが、径はバンプ電極28の径と同じである。)を形成した後に、全面にパッシベーション層20(酸化シリコン16b、窒化シリコン18からなる。)が形成される。酸化シリコン16bを、HDPに比して密度の低いプラズマを用いて形成したCVD−SiO2膜(例えば、TEOS/O2−CVDや、SiH4/N2O−CVD)としたが、第1の実施の形態と同じようにHDP−SiO2としてもよい。
図10(A)に示すように、パッド電極14の径よりも小さい外径をもち、パッド電極14の一部を露出させるためにパッシベーション層20に形成される開口部15aの径よりも大きな内径をもつ、例えば、円形リング状の凸部を感光性樹脂等により絶縁物リングを形成し、障壁リング34とする。この障壁リング34は、パッシベーション層20上に凸部として形成され、下地金属層が連続して続く部分の距離及び面積を延長させるためのものであり、サイドエッチングの発生の影響を抑制するためのものである。また、障壁リング34を導電性材料によって形成してもよいし、酸化シリコン、窒化シリコン等で形成してもよい。
図10(A)に示すように、パッド電極14上のパッシベーション層20に、障壁リング34の内径よりも小さく、パッド電極14の径よりも小さな径をもつ開口部15aを形成する。なお、S1eの工程とS1cの工程とを入れ換えて実行してもよい。
従って、本実施の形態では、下地金属層22の不要部分をウェットエッチングで除去する際に、サイドエッチング部分36が生じても、バリア金属層26の下部に、サイドエッチングされることなく残る下地金属層22の面積が、従来技術よりも大きくなり、第1の実施の形態と同様の効果を生じる。
本実施の形態では、第1から第3の各実施の形態において、複数の障壁、例えば、二重の障壁を形成してバンプ電極の形成を行う。
本実施の形態では、第1から第3の各実施の形態における異なるタイプの障壁30、32、34を組み合わせて、二重の障壁を形成してバンプ電極の形成を行う。
障壁30、32、34、バンプ28の形成手順は、第1から第3の実施の形態を参照すれば、明らかである。
図14は、本発明の各実施の形態におけるサイドエッチング36の比較を説明するZ−Z部の断面図である。
図14(E)は、第3の実施の形態において、障壁34の高さを高くした場合のサイドエッチング36の発生状況を示している。下地金属層22とバリア金属層26との接合面積が、第3の実施の形態の場合よりも増大するので、サイドエッチング36の影響は、第3の実施の形態の場合よりも少なくなる。
