請求項8記載の発明は、請求項5乃至7のいずれか1項記載の発明において、前記堰き止め部が、前記機能素子上に突出するように形成された突堤部であるものである。
請求項9記載の発明は、請求項5乃至7のいずれか1項記載の発明において、前記堰き止め部が、前記機能素子上に設けた保護膜によって形成された溝部であるものである。
すなわち、本発明方法の場合は、機能素子の機能部に対応する孔部を有するパッケージ構成部材を当該孔部を機能素子の機能部に対向させた状態で突堤部に当接させてパッケージ構成部材を液状の封止樹脂に接触させることにより、パッケージ構成部材の下面と機能素子との間の微小な隙間において封止樹脂の表面張力によって孔部の縁部で堰き止め、これにより、液状の封止樹脂にパッケージ構成部材の孔部とほぼ同じ大きさの開口部を形成する。そして、この状態で封止樹脂を硬化させることにより、本発明方法によって得られた機能素子実装モジュールは、機能素子の機能部が露出した状態となっており、このため特殊なコーティングを施した高価なガラスを用いることなく例えば青紫レーザー光のような短波長の光を減衰させずに確実に入出力することができ、更には放熱性に優れた機能素子実装モジュールを提供することができる。
また、本発明によれば、放熱性に優れ、かつ、非常に小型の機能素子実装モジュールを提供することができる。
図1(a)〜(d)は、本発明に係る機能素子実装モジュールの例として光機能素子実装モジュールの製造方法の実施の形態を示す断面構成図、図2は、同光機能素子実装モジュールの実施の形態を示す断面構成図である。
その他の構成及び作用効果については上述の実施の形態と同一であるのでその詳細な説明を省略する。
また、図6(a)は、同機能素子モジュールの断面構成図、図6(b)は、同機能素子モジュールの封止前の外観構成を示す平面図である。
以下、上記実施の形態と対応する部分には同一の符号を付しその詳細な説明を省略する。
また、本発明の場合、溝部32の大きさ及び形状は特に限定されることはないが、封止樹脂8の機能部露出用空間10Aへの流れ込みを考慮すると、パッケージ構成部材9の孔部9Aの形状に対応するように、例えば、孔部9Aとほぼ同じ大きさの矩形リング形状に形成することが好ましい。
なお、本実施の形態の機能素子モジュール1Dは、例えば図5に示す実施の形態と同一の方法によって作成することができる。
また、図8(b)に示す機能素子実装モジュール1Fは、上述した機能素子実装モジュール1Cのパッケージ構成部材9上に、ガス排出口14を有しない保護用被覆部材13を設けたものである。
これら場合、保護用被覆部材13は、上記実施の形態と同一の方法によって設けることができる。
この場合、保護フィルム15は、上記実施の形態と同一の方法によって設けることができる。
例えば、上述の実施の形態においては、突堤部をリング形状に形成したが、液状の封止樹脂を確実に堰き止められる限り、他の形状に形成することも可能である。
