Description
まず、ガラス成分の酸化物粉末を1200℃に加熱し、溶融状態で撹拌する。そして、ガラスを固化した後、ガラス封止部6の厚さに対応するようスライスして封止前ガラス11を板状に加工する(板状加工工程)。この後、封止前ガラス11に、後述するように、各LED素子2に対応する凹部11aを形成する。
図3(a)に示すように、複数のLED素子2を縦及び横について等間隔で搭載基板3に搭載する(搭載工程)。本実施形態においては、搭載基板3の中央側が各LED素子2の搭載領域10をなしている。具体的には、搭載基板3の回路パターン4の表面パターン41に複数のLED素子2を各Auバンプ28によって電気的に接合する。本実施形態においては、p側2点、n側1点の合計3点のバンプ接合が施される。
