Description
少なくとも1つの実施形態によれば、半導体チップの底面は、放射線通過面および放射線出射面に対してそれぞれ垂直である。
半導体チップを準備する工程、
半導体チップを少なくとも部分的にコーティング材料で囲む工程、および
保護層を少なくとも部分的にコーティング材料上に付与する工程
を含む。
まず、電子部品をキャリア上に実装し、その後の保護層の除去を、例えば溶媒浴中で容易に行う。これにより、電子部品が、有害な環境影響や汚染から最後まで保護されるため、エンドユーザーによる取り扱い性が大幅に向上する。したがって、散乱光がなく、汚染物質/粒子によるレーザ放射の吸収による絶対出力の低下もないため、光の取り出しが改善される。一方、電子部品の汚染や、場合によっては実装後の故障の可能性が、大幅に低減される。
ここで、半導体チップ2は、例えば全方向に電磁放射線を放射することができる。さらに、例えば、上面11上に配置された保護層4は、放射線出射面10上に配置された保護層4のより良好な接着に役立つことができる。
