Description
図1は、本発明の実施の形態1における半導体素子の積層構造体10を示す断面図である。この積層構造体10は、つぎのような化合物半導体層で形成されている。なお、エピタキシャルウエハは上記積層構造体を含む半導体素子を形成する前段階の中間製品と位置づけられ、エピタキシャルウエハ単独で、市販されるものである。以後の化合物半導体層の説明において、半導体素子という場合、エピタキシャルウエハも含まれているものと解釈する。
積層構造体10:(InP基板1/InGaAsバッファ層2/GaInNAs受光層3/AlInAs窓層4)
各層の厚みは、大雑把に、InGaAsバッファ層2は1μm〜2μm程度、N含有InGaAs系層であるGaInNAs受光層3は2μm〜3μm、AlInAs窓層4は0.5μm〜1.5μmである。半導体受光素子をフォトダイオードとする場合には、AlInAs窓層4上にマスクパターンを設け、p型不純物をAlInAs窓層4を通して、GaInNAs受光層3に届くように導入して、pn接合またはpin接合を形成する。その後、AlInAs窓層4のp型領域上にp部電極を、またInP基板1またはInGaAsバッファ層2にオーミック接続するn部電極を形成する。
(1)参考例として挙げる操作の方法であるが、N含有InGaAs系受光層の下地バッファ層を形成した後、N含有InGaAs受光層を形成するための各セルを作動開始させ、各セルから出射される分子線を基板シャッタで受けて、所定時間経過させる。これによって、成長初期の分子線は基板シャッタで遮られて、下地バッファ層を含む積層構造体に到達しない。所定時間経過後に、基板シャッタを開状態にすることにより、水素濃度の低い、フラット濃度部分に相当する分子線を最初の成長から寄与させることができる。この操作には、しかしながら、下地バッファ層は、形成された後、時間が経過すると表面に凹凸ができ、欠陥密度増大の原因になるという短所がある。
(2)N含有InGaAs系受光層の初期における成長速度を遅くする。(2)の操作では、基本的に、N含有InGaAs系受光層の各構成元素のセルのシャッタを、短時間ピッチで開閉しながら成長させる。そして、成長初期段階では、協働して各セルとも、閉状態時間の開状態時間に対する割合を大きくして、成長速度を極力遅くする。これにより、成長初期の水素を高濃度に含む部分の多くは、各セルシャッタに遮られて、水素高濃度層3aの厚みはより薄くされる。この操作(2)によって、水素高濃度層の厚み制御が可能である。
(本発明例):積層構造10の各層は、MBE法によって成膜した。まずInP基板1にInGaAsバッファ層2を厚み1.5μmにエピタキシャル成長させる。InGaAsバッファ層2成長の時、Siをドーピングしてキャリア濃度5×1016個/cm3のn導電型とした。次に、GaInNAs受光層3を、厚み2.5μmにエピタキシャル成長させた。成長温度は500℃とした。III族元素の組成は、Ga46%、In54%とし、V族元素はAs98.5%、残部Nとした。ドーピングはしていない。次に、AlInAs窓層4をエピタキシャル成長させた。このGaInNAs受光層3の成長の際、水素高濃度層3aを下面から0.5μm以下の厚み範囲に限定するように、原料および成長条件を選択した。III族元素は、In52%、残部Alとした。この後、RTA(Rapid Thermal Annealing)によって660℃×1分間の脱水素熱処理を行った。
(比較例1)
比較例1は、本発明例と同じ積層構造をMBE法によって形成した。ただし、InGaAsバッファ層については、ドーピングをせず、厚みを0.15μmとした。そして、本発明例との根本的な相違点は、MBE法で積層構造を形成したままで、脱水素の熱処理を行っていないことである。
(比較例2)
比較例2では、本発明例と同じ積層構造をOMVPE(Organometallic Vapor Phase Epitaxy)法で形成した。そして、積層構造を形成したままで、脱水素熱処理は行っていない。
