d)誘電体の表面全体に下塗り層を析出し又は作られた溝及びビアの壁にのみ下塗り層を析出し、
e)下塗り層に金属層を析出し(アディティブ工程)、溝及びビアはそこに導体構造を形成するために金属で完全に満たされ、
f)下塗り層が方法ステップd)で表面全体に析出されて誘電体を露光するため溝及びビアを除いて金属層と下塗り層を除去する、方法ステップを有する。
g)溝及びビアを具備した誘電体に別な誘電体を析出し、
h)ステップc)〜f)を繰り返す
i)プリント基板が誘電体を具備する。
ii)ビアを有する回路パターンのための凹部が誘電体に形成される。金属基層の面に作られるべき配線面との導電接続を確立するために、ビアは金属基層と同じ深さに作られる。オプションで、ビアは凹部に形成される。金属基層はレーザーアブレーションの間ランド領域として働き、一部は金属めっきの間電流を運ぶ。
iii)ビアを有する凹部の壁が下塗り層により活性化される。
iv)電気めっきによって、ビアを有する凹部のボリュームを完全に満たすように金属が下塗り層に析出される。
e)過度金属が除去される。
v)半導体チップが回路キャリア誘電体に埋設される(チップインポリマー技術)。同様に、半導体チップは、回路キャリアに析出して終端層を形成する永久レジスト又は第2フォトレジストに埋設されてもよい。これらの場合、回路キャリア上の回路パターンへの電気接続がチップ上の接触パッドに形成される。この目的のために、より具体的には、埋設されたチップ上の接触パッドへの付加的なビアが接続を確立するために埋設材料に形成される。
