Abstract
【解決手段】金属基板20の片面に絶縁層22を形成し、上記金属基板20に形成されたアライメントマークを用いて第1のフォトマスクを位置決めして露光・現像を行うことにより導体層28を形成した後、その反対側の面に、同じく上記アライメントマークを用いて第2のフォトマスクを位置決めして露光・現像を行うことにより導体層28のパッド28aに実装される発光素子40と光導波路フィルム41との光結合用開口36を形成し、上記パッド28aに発光素子40を実装した後、上記光結合用開口36を利用して、光導波路フィルム41を金属基板20に固定し、両者を光結合させるようにした。

Description
厚み25μmのSUS基板上に、厚み10μmで感光性ポリイミドを塗布した後、フォトマスクを用いて絶縁層形成予定部に露光し、下層PEBにより露光部と未露光部のポリイミドの溶解度に差をつけた。そして、現像液によって未露光部を除去した後、加熱によりポリイミドキュアを行い、硬化した露光部を絶縁層とした。
上記実施例1と同様にして、SUS基板上に、絶縁層を介して導体層(不用なシード層除去済)が形成された回路基板を作製した。そして、上記回路基板の両面に、ドライフィルムレジストをラミネートし、上記絶縁層および導体層が形成された方と反対側のドライフィルムレジストに対し、前記SUS基板に設けられたアライメントマークを利用してフォトマスクの位置合わせを行い、フォトリソによる露光・現像を行って露光部分のドライフィルムレジストを除去することにより、光結合用開口パターンと、PMTコネクタ取付用の位置決め孔(2個一対)となる開口パターンとを、素子が実装されるパッドに対し正確な位置関係で形成した。
