Abstract
【解決手段】 ドナー基板10Aは、所定のパターンによる第1の電鋳膜2と、第1の電鋳膜2上に形成された軟質膜の第2の電鋳膜3とにより構成された複数の導電膜パターン11A〜11Eを有する。ドナー基板10Aとターゲット基板との圧接、離間を繰り返すことにより、ドナー基板10A上の各導電膜パターン11A〜11Eが順次ターゲット基板上に転写してターゲット基板上に電鋳積層構造体が形成される。
【選択図】 図1
Description
この場合、前記研磨工程は、前記金属基板の表面を研磨によりRa値で10nm以下にするのが好ましい。金属基板の表面粗さを小さくすることにより、金属基板の表面に離型層を形成しなくても導電膜パターンを第1の基板から第2の基板側へ転写することができる。
本発明の第1の実施の形態に係る電鋳積層構造体の製造方法をドナー基板の作製と導電膜パターンの転写に分けて説明する。
図1(a)〜(f)は、第1の実施の形態に係るドナー基板の作製工程を示す。まず、ステンレス等の鉄系の金属、または銅等の非鉄系の金属からなる第1の基板としての金属基板1を用意する。金属基板1の板厚は、0.1〜5mm、望ましくは0.5〜1mmのものを用いる。
図2(a)〜(f)は、導電膜パターンの転写工程を示す。この電鋳積層構造体は、図1の方法により作製したドナー基板10A上の5つの導電膜パターン11A〜11Eを第2の基板としてのターゲット基板20の表面に順次転写して、積層することにより作製される。
この第1の実施の形態によれば、下記の効果を奏する。
(イ)導電膜パターン11は、構造体を主に形成する硬度の高いニッケルによる第1の電鋳膜2と、第1の電鋳膜2よりも硬度の低い金による第2の電鋳膜3とによる2層構造であるため、第1の電鋳膜2の膜厚に差が生じても、積層構造体を精度良く、また、歩留まり良く作製することができる。
(ロ)転写時の上部ステージおよび下部ステージにより導電膜パターン11に発生する圧接応力は、第2の金属膜3の降伏応力以上で、かつ第1の金属膜2の降伏応力以下にすることにより、導電膜パターン11の膜厚が均一化され、高精度な電鋳積層相構造体を得ることができる。
(ハ)金属基板1の表面粗さをRa値で10nm以下とすることにより、金属基板1から導電膜パターン11を容易に剥離し、ターゲット基板20へ転写することができる。
本発明の第2の実施の形態に係る電鋳積層構造体の製造方法をドナー基板の作製と導電膜パターンの転写に分けて説明する。
図4(a)〜(f)は、第2の実施の形態に係るドナー基板の作製工程を示す。まず、図4(a)に示すように、Siウェハ基板101上に、離型層102を形成し、この上に導電層103を形成し、その上に、例えば30μmの厚みに厚膜レジストを塗布してレジスト膜4を形成する。
次に、第1の実施の形態と同様に、ドナー基板10B上の5つの導電膜パターン110A〜110Eをターゲット基板20の表面に順次転写して、積層することにより電鋳積層構造体が作製される。
この第2の実施の形態によれば、導電膜パターン110は、構造体を主に形成する硬度の高いニッケルによる第1の電鋳膜2と、第1の電鋳膜2よりも硬度の低い金による第2の電鋳膜3と、導電層103とからなる3層構造であるため、第1の電鋳膜2の膜厚に差が生じても、積層構造体を精度良く、また、歩留まり良く作製することができる。
なお、本発明は、上記各実施の形態に限定されず、本発明の要旨を逸脱あるいは変更しない範囲内で種々な変形が可能である。
