Description
本発明は、光電子分野に関し、より具体的には光電子部品のパッケージングおよび製造に関する。より具体的には、本発明は、光電子モジュールおよびその製造方法と、このような光電子モジュール、特にフラッシュモジュールである光電子モジュールを含む電化製品および電子機器に関する。さらに、シーンを撮影する方法が提供される。本発明は、特許請求の範囲のオープンクローズ表現に基づく方法および装置に関する。
米国特許出願2010/0327164Alからは、光電子モジュール、より具体的には近接センサが知られている。このような光電子モジュールの製造において、発光体チップおよび光検出器チップは、トランスファー成形技術を用いてオーバーモールドされ、これらのチップの上方にレンズを形成する。
用語の定義
「能動光学部品」:たとえば、フォトダイオード、イメージセンサ、LED、OLED、レーザチップなどのような光検知素子または発光素子である。能動光学部品は、ベアチップまたはパッケージ、すなわちパッケージ化された部品であってもよい。
「縦方向」:「ウエハ」を参照する。
本発明の1つの目的は、特にコンパクトおよび/または有用な光電子モジュールを製造することである。また、複数のこのようなモジュールを備える電化製品、このようなモジュールを少なくとも1つ備える電子機器およびこのようなモジュールを製造する方法、ならびにシーンを撮影する方法を提供する。
本発明の別の目的は、光電子モジュールを製造する特に高速な方法および/または光電子モジュールを製造する特に簡単な方法を提供する。
本発明の別の目的は、特に少ない製造ステップ数で製造可能な光電子モジュールおよび対応の製造方法を提供することである。
本発明の別の目的は、録画されるシーンの特に良好な照明を、特に小型電子機器を用いて提供することが可能にすることである。
これらの実施形態は、光電子モジュールの特に良好な生産性に貢献することができる。
前述した実施形態の1つまたは複数と組合わせることができる方法の一実施形態において、スペーサウエハは、光を実質的に減衰または遮断する材料から作れる。このことは、製造の簡素化に貢献することができる。
以下、本発明を実施例および添付図面を用いてより詳細に説明する。
図1は、光電子モジュール1の概略断面図を示している。図示の断面は、縦方向の断面図である。図2は、図1のモジュールの構成要素のさまざまな概略側断面図を示している。図1において、これらの側面断面の近似位置は、s1〜s5および破線によって示されている。s4およびs5に対し、矢印で観察方向を示している。
図13は、導光素子11を備える光学部材Oを有する光電子モジュール1を含む電子機器10の細部を示す概略断面図である。電子機器10は、たとえば円形の断面を有する貫通孔として設けられた開口52を有するハウジング51を備える。光学系1は、導光素子11と、ベースプレート12と、特に少なくとも1枚のレンズ素子である少なくとも1つの受動光学部品Lとを備える。図13の実施形態において、設けられた受動光学部品が1つのみであるが、上記の教示に従って、光電子モジュール1の設計目的に応じて、2つまたは3つまたはそれ以上の受動光学部品を設けることができることは明らかである。導光部材11とベースプレート12とは、個別の部品であってもよく、一体部品として形成されてもよい。導光素子11または少なくともその一部は、開口52内に配置されている。その形状は、開口52の形状を補完するように設計されている。
図15は、図13に示された光学部材Oを含む光学ウエハ30の概略上面図である。直線は、分割が行われる場所を示している。ウエハスケールの製造方法を用いれば、このような光学部材Oの大量生産は可能である。このように、高整列精度および高収量、高生産性の製造は、達成することができる。
