Description
図1に示すように、本実施形態に係る多層配線板1は、隣接するMPU(Micro-Processing Unit)(電子部品)2及びDRAM(Dynamic Random Access Memory)(電子部品)3を実装するための配線板であって、主配線板20と該主配線板20に形成された配線構造体10とを備える。主配線板20は、いわゆるコア基板を有しないコアレス基板であり、複数の主絶縁層及び主導体層を交互に積層してなるビルドアップ多層積層配線板である。また、本実施形態において、主導体層及び後述の副導体層は、電気回路を構成する配線層であり、その配置位置によってパッドと配線パターン等を含む場合もあれば、電子部品を実装するための実装パッドのみを含む場合もある。
まず、支持板110を準備する。支持板110は、例えば、低熱膨張率を有する表面の平坦なガラス板である。但し、支持板110はこれに限定せず、例えば、Si、金属板等でも良い。続いて、支持板110の上に剥離層111を形成する(図3A参照)。剥離層111に用いられる剥離剤として、例えば、ブリューワサイエンス社のWafer Bondが挙げられる。続いて、剥離層111の上に樹脂からなる副絶縁層100を形成する。副絶縁層100は、例えば、感光性ポリイミド樹脂からなる絶縁材を塗布して加熱することにより形成されている。続いて、剥離層111と副絶縁層100に加熱処理を施すことでこれらを接着させる。
以下、図4A〜図4Oを参照し配線構造体10を主配線板20の内部に埋め込んで積層して多層配線板1を作製する方法について説明する。そして、配線構造体10を主配線板20の内部に埋め込んで積層し多層配線板1を作製する際に、配線構造体10の副導体層103と主配線板20の主導体層201とを絶縁するように各工程が行われる。
以下、図7を参照して本発明の第2実施形態を説明する。この実施形態に係る多層配線板5は、配線構造体10が主配線板20から外部に突出する点において上述の第1実施形態と異なっているが、その他の構造等は第1実施形態と同様である。
以下、図8を参照して本発明の第3実施形態を説明する。この実施形態に係る多層配線板6は、放熱部材114を備える点において上述の第1実施形態と異なっているが、その他の構造等は第1実施形態と同様である。
以下、図9を参照して本発明の第4実施形態を説明する。この実施形態に係る多層配線板7は、副ビア導体115の拡径方向及び主ビア導体210,211,212,213の拡径方向が同じである点において上述の第1実施形態と異なっているが、その他の構造等は第1実施形態と同様である。
以下、図10を参照して本発明の第5実施形態を説明する。この実施形態に係る多層配線板8は、副実装パッド104の上表面104aが主実装パッド200の上表面200aよりも低く配置される点において上述の第1実施形態と異なっているが、その他の構造等は第1実施形態と同様である。
以下、図11を参照して本発明の第6実施形態を説明する。この実施形態に係る多層配線板9は、主実装パッド200の上表面200aが主絶縁層202の上表面202aよりも低く配置される点において上述の第1実施形態と異なっているが、その他の構造等は第1実施形態と同様である。
