Abstract
【解決手段】基板の一方の面に半導体層を有する発光素子と、この基板の他方の面を、絶縁性接着剤を介して表面に固定する実装基板とを備え、基板の他方の面に凹凸部を有し、凹凸部における複数の凹部に絶縁性接着剤が充填され、複数の凸部が実装基板に接触した状態で、発光素子が実装基板に実装した構成とした。
【選択図】図1
Description
本発明の実施形態1における構成例について、図1を用いて説明する。
[実施形態1の作用の説明]
次に、基板3の他方の面に形成された凹凸部5の作用について、図2を用いて説明する。
実装基板の銅の熱伝導率が398[W/m・K]、絶縁性接着剤の熱伝導率が0.26[W/m・K]である。つまり、接着剤に比べ、サファイアは約1000倍も熱伝導率が高いので、本実施形態の構成によれば、半導体層4で発生した熱の殆どは、絶縁性接着剤13のルートLよりも、サファイアからなる凸部5bのルートHを介して、実装基板11に伝わり、外部に放熱される。
[実施形態1の製造方法の説明]
次に、本実施形態1の発光デバイス1の製造方法について図4A〜図4Cを用いて説明する。
[変形例1の構成と作用の説明]
次に、実施形態1における、発光素子2の変形例1の構成および作用について、図5を用いて説明する。なお、図5(a)は発光素子2の正面図を、図(b)図が左側面図を、図(c)が下面図を示している。
[変形例2、変形例3の構成と作用の説明]
次に、変形例2および変形例3における発光素子2の構成と作用について、図6を用いて説明する。図6(a)は、変形例2の構成を、図6(b)で変形例3の構成を示している。
次に、実施形態2の発光素子2の構成例と作用について、図7を用いて説明する。
