Description
ことが困難となる。これにより製品ごとに光の向きや信頼性、放熱性と放熱性に起因する輝度にばらつきが発生し、歩留まりが低下するという問題があった。
図1は本発明に係る半導体デバイスの基板を示す概略図であり、(a)は平面図で(b)はA−A切断部端面図である。基板1は、金属基板2と、金属基板の一部に形成された凹部に充填された絶縁層3と、金属基板2上および絶縁層3上にそれぞれ形成された導電パターン4、5からなる。
としても一定の効果を有する。半導体素子7としてLEDを実装する場合、N層の端子に比べて面積が大きく熱伝導量が多いP層の端子に矢印Hのような熱伝導路を形成することでより効果的に放熱することができる。
なお、図4〜図6の説明は、金属基板2に絶縁層3はいかなる形状にも配置可能であり、また、絶縁層3上および金属基板2上における導電パターン4、5もいかなる形状にも配置可能であることを示すものである。
熱伝導性の良い一般的に用いられる金属基板であればどのような基板を用いても良い。ただし、半導体素子が半導体発光素子である場合、アルミ基板や銀にてコーティングされた金属基板であることが望ましい。基板で効率良く光を反射し、光の利用効率が向上するからである。
金属基板凹部への絶縁層充填について図7A(d)、図7A(e)を用いて説明する。凹部13に絶縁層3を形成する部材を充填するのだが、その際に、図7A(d)のように金属基板2の高さを超えて充填し、フォトレジスト12と一緒に研磨してフォトレジストを排除すると共に金属基板と絶縁層を図7A(e)のように同一高さに調整する。また、こうすることで金属基板表面の不純物を排除することが出来るため、配線形成の密着性が向上する。半導体発光素子を実装する場合、絶縁層を形成する絶縁部材として、反射率の良い白色レジスト(太陽インキ製造株式会社製「 PSR−4000LEW1」)が望ましいが、半導体素子が発光しない半導体の場合では、エポキシ樹脂等反射率によらない絶縁性樹脂を用いても良い。
