Description
図1は、本発明の実施の形態1を模式的に示す。図1では、101は、例えば、Si基板、102は、例えば、Cr層からなる金属層1である。103は、例えば、Au層からなる金属層2である。金属層1は、金属層2と基板、例えば、Si基板の密着性を確保するための密着層である。
n−GaAs/n−AlxGa1−xAs/n−AlyGa1−yAs/p−AlzGa1−zAs/p−GaAsとすることができる。ここで、例えば、z>y、x>yとすることができる。すなわち、n−AlyGa1−yAsを活性層(発光層)とする発光ダイオードを形成するダブルヘテロ・エピタキシャル層構造とすることができる。
図15は、実施の形態2を示す。図15において、801は基板、例えばSi基板、802は、例えば、Cr層からなる金属層であり、Si基板と金属層の密着性を保持するための密着層である。803は、例えば、Pd層からなる高融点金属層である。804は、例えばIn層からなる低融点金属層である。805は、例えば、Ti/Pt/Auからなる金属層であり、半導体薄膜層806の接合面とオーミックコンタクトを形成する。821は、金属層803と金属層804とが反応することで形成される共晶層、例えば、PdIn、PdIn3等である。822は、前記金属層805と前記低融点金属層804とが反応してできる反応層である。低融点金属層804は、反応後に、低融点の金属単層の領域が残留していない状態が望ましい。ここで説明した形態を備えた素子の具体例としては、例えば実施形態1で説明した素子を挙げることができる。
実施の形態3は、実施の形態1及び実施の形態2において、半導体薄膜と、この半導体基板と異種材料の基板とをボンディングする際に露出する低融点金属の表面処理に関する。実施の形態1と実施の形態2において、表面に露出する低融点金属表面を真空中または大気圧中で、例えばN2プラズマ、Arプラズマ等を照射し、表面の酸化皮膜を除去する。次に、真空中、不活性ガス、又はN2ガス等を満たした酸化を防止する雰囲気中でボンディング面を密着させる。次に、低融点金属の融点よりも高い温度で加熱し、構成金属を反応させる。低融点金属表面は、表面を活性化する材料を使って活性化してボンディングすることもできる。このような活性化する材料には、例えば、エタノールアミン等のアミン類にホウフッ化物やホウフッ化物金属塩を添加したもの、その他ハロゲン化物などがある。
102 金属層1、
103 金属層2、
104 低融点金属層、
105 半導体薄膜層、
