Description
図1および図2は、本開示のある実施形態による製造方法によって得られる発光装置の例示的な構成を示す。図1および図2は、それぞれ、発光装置の模式的な断面図および底面図である。参考のために、図1および図2には、互いに直交するx軸、y軸およびz軸が示されている。本開示の他の図面においても、x軸、y軸およびz軸を示すことがある。
以下、図面を参照しながら、本開示の実施形態による発光装置の製造方法の例を説明する。ここでは、図1および図2を参照して説明した発光装置100の例示的な製造方法を説明する。
図5は、本開示のある実施形態による発光装置の製造方法の概略を示すフローチャートである。図6〜図19は、本開示のある実施形態による発光装置の製造方法の製造工程を説明するための図である。なお、図6〜図19の各々には、模式的な平面図と側面図(または断面図)とがあわせて示されている。
なお、図3および図4を参照して説明した構造は、例えば以下のようにして得ることができる。図16に示すように、まず、支持層300上に保護素子120Aを配置する。次に、図17に示すように、保護素子120Aの上面120u側から保護素子120Aを覆うように発光素子110を支持層300上に配置する。このとき、図17の上段に例示するように、発光素子110として、保護素子120Aに物理的に干渉しないような形状を有する正極112および負極114を有する素子を用いる。保護素子120Aの上面120uが例えば絶縁層を有する等、保護素子120Aと発光素子110とがこれらの間で電気的に絶縁されている場合には、保護素子120Aの上面120uと、発光素子110の下面110bとが互いに接触していても構わない。
以下、図20〜図37を参照しながら、本開示の他のある実施形態による発光装置の製造方法を説明する。図20は、本開示の他のある実施形態による発光装置の製造方法の概略を示すフローチャートである。図21〜図37は、本開示の他のある実施形態による発光装置の製造方法の製造工程を説明するための図である。
なお、第1導電部材122bおよび第2導電部材124bの構成は、上述の例に限定されず、例えば、Auバンプに代えてリード線等を用いることも可能である。
