高誘電体層424とする。その後、スパッタ等の真空蒸着装置を用いて高誘電体層424の上に銅、白金、金等の金属層を形成し更にこの金属層上に電解めっき等で銅、ニッケル、スズ等の金属を10μm程度足すことにより、上部金属層426(後に上面電極42Aの一部をなす)を形成する。この結果、高誘電体シート420が得られる。
.0mjのエネルギー密度、2ショットの条件でφ65μmのスルーホール472を形成した(図6(b)参照)。その後、60g/Lの過マンガン酸を含む80℃の溶液に10分間浸漬し樹脂絶縁シート470の表面を粗化した。次に、粗化したあとの作製途中の基板を、中和溶液(シプレイ社製、商品名サーキュポジットMLBニュートラライザー)に浸漬してから水洗いした。さらに、基板を塩化パラジウム(PbCl2)と塩化第一スズ(SnCl2)とを含む触媒液中に浸漬しパラジウム金属を析出させることにより、樹脂
絶縁シート470の表面(スルーホール472の内壁を含む)にパラジウム触媒を付与した。次に、無電解銅めっき水溶液中に基板を浸漬し、34℃の液温度で40分処理することにより、樹脂絶縁シート470の表面及びスルーホール472の壁面に厚さ0.6〜3.0μmの無電解銅めっき膜を形成した(図示せず)。なお、無電解銅めっき水溶液は以下の組成のものを使用した。硫酸銅:0.03mol/L、EDTA:0.200mol/L、HCHO:0.1g/L、NaOH:0.1mol/L、α,α′−ビピリジル:100mg/L、ポリエチレングリコール(PEG)0.1g/L。次に、無電解銅めっき膜上に、ドライフィルムを形成し、以下の条件で厚さ25μmの電解銅めっき膜を形成した(図示せず)。なお、電解銅めっき液は以下の組成のものを使用した。硫酸:200g/L、硫酸銅:80g/L、添加剤:19.5 ml/L(アトテックジャパン社製、カパラシドGL)。また、電解銅めっきは以下の条件で行った。電流密度1A/dm2、時間115分、温度23±2℃。続いて、ドライフィルムを剥がし、図1の多層プリント配線板10を得た(図6(c)参照)。ここで、樹脂絶縁シート470が応力緩和部50に相当する。また、スルーホール472を埋めた銅めっき膜474の上部がグランド用パッド61A,電源用パッド62Aに相当する。なお、これと同時並行的にグランド用パッド61B,電源用パッド62Bも形成した。
図8は第2実施形態の多層プリント配線板110の部分的な縦断面図である。この多層プリント配線板110は、第1実施形態と同様、1チップに第1及び第2プロセッサコア81A,81Bを含むデュアルコアプロセッサ80(図1参照)を搭載可能な実装部160と、各プロセッサコアごとに独立して形成された電源ラインと、各プロセッサコアごとに独立して形成されたグランドラインと、各プロセッサコアごとに独立して形成された層状コンデンサとを備えたものであるが、ここでは説明の便宜上、第1プロセッサコア81Aに対応する第1層状コンデンサ140Aを中心として説明するものとする。なお、第2層状コンデンサの構成は第1層状コンデンサ140Aと略同じである。
Aとで構成された第1層状コンデンサ140Aと、同じく層間絶縁層120に積層され第1層状コンデンサ140Aと同じ構成の第2層状コンデンサ(図示せず)と、第1層状コンデンサ140A及び第2層状コンデンサに積層され弾性材料で形成された応力緩和部150と、デュアルコアプロセッサ80(図1参照)を実装する実装部160と、この実装部160の周囲に設けられたチップコンデンサ配置領域170Aとを備えている。
(1)乾燥窒素中において、濃度1.0モル/リットルとなるように秤量したジエトキシバリウムとビテトライソプロポキシドチタンを、脱水したメタノールと2−メトキシエタノールとの混合溶媒(体積比3:2)に溶解し、室温の窒素雰囲気下で3日間攪拌してバリウムとチタンのアルコキシド前駆体組成物溶液を調整した。次いで、この前駆体組成物
溶液を0℃に保ちながら攪拌し、あらかじめ脱炭酸した水を0.5マイクロリットル/分の速度で窒素気流中で噴霧して加水分解した。
(2)このようにして作製されたゾル−ゲル溶液を、0.2ミクロンのフィルターを通し、析出物等をろ過した。
(3)上記(2)で作製したろ過液を厚さ12μmの銅箔522(後に下面電極141Aとなる)上に1500rpmで1分間スピンコートした。溶液をスピンコートした基板を150℃に保持されたホットプレート上に3分間置き乾燥した。その後基板を850℃に保持された電気炉中に挿入し、15分間焼成を行った。ここで、1回のスピンコート/乾燥/焼成で得られる膜厚が0.03μmとなるようゾルーゲル液の粘度を調整した。なお、下面電極141Aとしては銅の他に、ニッケル、白金、金、銀等を用いることもできる。
(4)スピンコート/乾燥/焼成を40回繰り返し1.2μmの高誘電体層524を得た。
(5)その後、スパッタ等の真空蒸着装置を用いて高誘電体層524の上に銅層を形成し更にこの銅層上に電解めっき等で銅を10μm程度足すことにより、銅箔526(後に上面電極142Aの一部をなす)を形成した。このようにして、高誘電体シート520を得た。誘電特性は、INPEDANCE/GAIN PHASE ANALYZER(ヒューレットパッカード社製、品名:4194A)を用い、周波数1kHz、温度25℃、OSCレベル1Vという条件で測定したところ、その比誘電率は、1,850であった。なお、真空蒸着は銅以外に白金、金等の金属層を形成してもよいし、電解めっきも銅以外にニッケル、スズ等の金属層を形成してもよい。また、高誘電体層をチタン酸バリウムとしたが、他のゾル−ゲル溶液を用いることで、高誘電体層をチタン酸ストロンチウム(SrTiO3)、酸化タンタル(TaO3、Ta2O5)、チタン酸ジルコン酸鉛(PZT)、チタン酸ジルコン酸ランタン鉛(
PLZT)、チタン酸ジルコン酸ニオブ鉛(PNZT)、チタン酸ジルコン酸カルシウム鉛(PCZT)及びチタン酸ジルコン酸ストロンチウム鉛(PSZT)のいずれかにすることも可能である。
通し銅箔522の表面に達するスルーホールである。ここで、スルーホール形成は、まず深いスルーホール530を形成し、続いて浅いスルーホール531を形成した。深さの調整はレーザショット数を変更することにより行った。具体的には、スルーホール531は日立ビアメカニクス(株)製のUVレーザ にて、出力3〜10W、周波数30〜60k
Hz、ショット数4という条件で行い、スルーホール530はショット数31とした以外は同条件で行った。その後、スルーホール530,531内に後述するスルーホール充填用樹脂532を充填し、80℃で1時間、120℃で1時間、150℃で30分乾燥した(図9(d)参照)。なお、スルーホール530,531は、図8に示した電源用パッド162Aとグランド用パッド161Aのすべて(30000個)に対応するようには形成しなかった。
径を介して2.0mjのエネルギー密度、1ショットでバイアホール560を形成した(図11(a)参照)。続いて、粗化処理し、150℃で3時間乾燥硬化し応力緩和シート550を完全硬化した。その後、触媒付与、化学銅、めっきレジスト形成、電気銅めっき、めっきレジスト剥離、クイックエチングの工程を施すことにより、バイアホール560を金属で充填すると共に最表層に各バイアホール560の上面にパッド(グランド用パッド161A,電源用パッド162A)を形成し、実装部160を有する多層プリント配線板110を得た(図11(b))。なお、ランド544及び銅箔542に接続されているグランド用パッド161Aはグランドラインに接続され、上部電極543に接続されている電源用パッド162Aは電源ラインに接続される。
図13は第3実施形態の多層プリント配線板210の部分的な縦断面図である。この多層プリント配線板210は、第1実施形態と同様、1チップに第1及び第2プロセッサコア81A,81Bを含むデュアルコアプロセッサ80(図1参照)を搭載可能な実装部260と、各プロセッサコアごとに独立して形成された電源ラインと、各プロセッサコアごとに独立して形成されたグランドラインと、各プロセッサコアごとに独立して形成された
層状コンデンサとを備えたものであるが、ここでは説明の便宜上、第1プロセッサコア81Aに対応する第1層状コンデンサ240Aを中心として説明するものとする。なお、第2層状コンデンサの構成は第1層状コンデンサ240Aと略同じである。
