Description
まず、基板107の上面全体において、上述したn型コンタクト層108、n型バッファ層109、吸収層106、p型バッファ層111、及びp型コンタクト層112を含む構造層を、MOCVD装置等を用いて成長させる。
次に、リソグラフィ技術を用いて、上述した構造層から、受光メサ部110、パッドメサ部120、及びダミーメサ部130A、130Bを分離することにより形成する。
その後、基板107の上面側全体に絶縁酸化膜であるパッシベーション膜114を形成する。パッシベーション膜114としては、半導体受光素子10に入光する光の波長(1.3μm帯もしくは1.55μm帯)に対して、低反射膜として機能するものを用いる。
次に、パッシベーション膜114における受光メサ部110の上面における受光部電極101が形成される領域に、環状のスルーホールを形成し、パッシベーション膜114から、p型コンタクト層112を露出させる。また、n型コンタクト層108の上面におけるn電極115が形成される領域にスルーホールを形成し、パッシベーション膜114から、n型コンタクト層108を露出させる。
その後、受光部電極101を、受光メサ部110の上面において形成されたパッシベーション膜のスルーホール内に形成する。受光部電極101は、上述したレジスト塗布工程、金属膜蒸着工程、リフトオフ工程により形成することができる。即ち、受光部電極101を形成しない領域全体に、レジストを形成し、当該レジストの上面及び、受光部電極101を形成する領域に金属膜を蒸着する。その後、レジストを除去することにより、レジスト上面に形成された金属膜を除去し、受光部電極101を形成する。
次に、上述したパッド電極102、n電極115、及びダミー電極131A、131Bを形成する。パッド電極102、n電極115、及びダミー電極131A、131Bの形成方法は、受光部電極形成工程と同様、レジスト塗布工程と、金属膜蒸着工程と、リフトオフ工程とを用いて形成することができる。なお、このパッド電極、n電極、ダミー電極形成工程は、上述した受光部電極形成工程の前に行ってもよく、同時に行ってもよく、また後にあってもよい。ただし、後述するブリッジ電極構成とは同時には行わない。
次に、ブリッジ電極103を形成する。ブリッジ電極103の形成方法は、図10を用いて上述したとおりであるため、その説明を省略する。なお、ブリッジ電極形成工程は、上述したパッド電極、n電極、ダミー電極形成工程の前に行っても良い。
最後に、半導体受光素子群をチッピングし、個辺化された半導体受光素子10を得る。なお、このチッピング工程においては、必ずしも一つの半導体受光素子10にチッピングする必要はなく、例えば、アレイ状に配列された複数の半導体受光素子10を含む半導体受光素子群としてチッピングしても構わない。
