Description
はじめに、本発明の実施の形態の概要を列挙する。
次に、本発明の実施の形態の詳細について説明する。
図1〜図3を参照して、実施の形態1に係る半導体素子100について説明する。本実施の形態に係る半導体素子100は、プレナー型の受光素子であり、ベース基板1と、ベース基板1の第1の主面1A上に形成された半導体層積層体2とを備える。
受光層4は、バッファ層3を介して第1の主面1A上に形成されており、多重量子井戸構造を有している。具体的には、受光層4は、GaSb層4aとヒ化インジウム(InAs)層4bとで構成される一つの量子井戸が100ペア程度積層された、タイプII型のInAs/GaSb多重量子井戸構造を有している。GaSb層4aの膜厚はたとえば3nm程度であり、InAs層4bの膜厚はたとえば3nm程度である。このときの受光層4のカットオフ波長は、5μm程度である。GaSb層4aおよびInAs層4bは、ともに意図的にドープされていない。受光層4中のTeの濃度は、1×1016cm−3以下であり、好ましくはSIMSにおいて検出限界以下である。受光層4中のTe濃度がこの範囲であれば、暗電流の増加を抑制することができる。さらに、空乏層が広がりやすくなるため、半導体素子の受光感度を向上させることができる。受光層4中の炭素の濃度は1×1016cm−3以下である。このようにすれば、受光層4において空乏層が広がりやすくなるため、半導体素子100の受光感度を向上させることができる。
まず、ベース基板1を準備する(工程(S10))。ベース基板1は、GaSb基板であり、たとえば亜鉛(Zn)などのp型不純物がドープされてp型の導電型を有している。
本実施の形態に係る半導体素子100は、GaSb層4a、InAs層4b、およびInSb層4cで構成されたタイプII型の量子井戸構造を有する受光層4を備えており、受光層4は全有機MOVPE法により形成されている。そのため、受光層4は高い結晶性を有し、結晶欠陥が少ない。その結果、本実施の形態に係る半導体素子100では、受光層4内において結晶欠陥を介して生じる発生電流を低減することができる。また、本実施の形態に係る半導体素子100において、受光層4を構成するGaSb層4a、InAs層4b、およびInSb層4cの各膜厚が全有機MOVPE法によって正確に制御されているため、所定のカットオフ波長を有することができる。
