Description
本開示に係る別の一態様の窒化物半導体デバイスは、半導体素子を備える。前記半導体素子は、III族元素(ここで、前記III族元素は、周期表の13族の群から選択される元素である)を含み所定結晶面を有する単結晶のIII族窒化物半導体部と単結晶のII-IV族窒化物半導体部とを備える窒化物半導体構造体の、前記II-IV族窒化物半導体部の少なくとも一部を含む。前記II-IV族窒化物半導体部は、前記III族窒化物半導体部の前記所定結晶面上に設けられており、II族元素(ここで、前記II族元素は、周期表の2族の群又は12族の群から選択される元素である)とIV族元素(ここで、前記IV族元素は、周期表の14族の群から選択される元素である)とを含み、前記III族窒化物半導体部とヘテロ接合されている。前記所定結晶面は、(0001)面以外の結晶面である。前記窒化物半導体デバイスは、前記半導体素子である第1半導体素子とは別に、前記III族窒化物半導体部に形成された第2半導体素子を更に備える。
(1)概要
以下では、実施形態1に係る窒化物半導体構造体1について、図1に基づいて説明する。
以下では、III族窒化物半導体部3に含まれるIII族窒化物半導体としてAlN結晶又はGaN結晶を採用し、II-IV族窒化物半導体部4に含まれるII-IV族窒化物半導体としてZnGeN2結晶を採用する場合についての所定結晶面の面方位の検討内容について説明する。
本願発明者は、III族窒化物半導体(例えば、GaN結晶又はAlN結晶)上にII-IV族窒化物半導体(例えば、ZnGeN2結晶)をヘテロエピタキシャル成長させる場合に、回転ドメインの乱立問題が発生することがあるという課題を見出した。この課題は、本願発明者がMOCVD(Metal Organic Chemical Vapor Deposition)法によってAlN結晶上にZnGeN2結晶を結晶成長させる研究開発を行い、そのZnGeN2結晶の結晶性、表面モフォロジ及び断面構造等を評価することで見出したものであり、特許文献1にはこのような課題について示唆も言及もされていない。
まず、III族窒化物半導体上に結晶成長したII-IV族窒化物半導体において、回転ドメインの乱立問題が発生することを説明する。
II-IV族窒化物半導体においてII族元素及びIV族元素それぞれが配置されるサイトを制御するためには、III族窒化物半導体において対称性の低い面を利用すること、さらにその面から成長されるII-IV族窒化物半導体の面方位も界面エネルギによって一意に定まることが必要である。界面構造の解析は困難であるため、ここでは計算科学を用いて界面の設計を行なっている。
以上の界面構造を実現するには、例えば、a面を主面とするAlN基板を用意し、そのAlN基板の主面上にZnGeN2を結晶成長させればよい。もしくは、m面を主面とするAlN基板の主面上にZnGeN2を結晶成長させてもよい。その結果として、回転ドメインの乱立を回避した、優れた結晶性を有するシングルドメイン(単結晶)のZnGeN2結晶を得ることができる。
実施形態1に係る窒化物半導体構造体1は、III族窒化物半導体部3と、II-IV族窒化物半導体部4と、を備える。III族窒化物半導体部3は、単結晶であり、所定結晶面(第1側面33)を有する。II-IV族窒化物半導体部4は、III族窒化物半導体部3の所定結晶面上に設けられており、単結晶である。II-IV族窒化物半導体部4は、III族窒化物半導体部3とヘテロ接合されている。所定結晶面(第1側面33)は、(0001)面以外の結晶面である。所定結晶面(第1側面33)は、例えば、(11-20)面である。
以下では、窒化物半導体デバイス10について図12に基づいて説明する。
以下では、実施形態2に係る窒化物半導体構造体1bについて、図13に基づいて説明する。実施形態2に係る窒化物半導体構造体1bに関し、実施形態1に係る窒化物半導体構造体1と同様の構成要素には同一の符合を付して説明を省略する。
以下では、実施形態3に係る窒化物半導体構造体1cについて、図15に基づいて説明する。実施形態3に係る窒化物半導体構造体1cに関し、実施形態1に係る窒化物半導体構造体1と同様の構成要素には同一の符合を付して説明を省略する。
以下、実施形態4に係る窒化物半導体構造体1eを備える窒化物半導体デバイス10eについて図20に基づいて説明する。なお、窒化物半導体デバイス10eに関し、実施形態1で説明した窒化物半導体デバイス10と同様の構成要素には同一の符合を付して説明を適宜省略する。
