Description
本発明例1の窒化物半導体結晶10は、図1および図2に示す製造装置100を用いて、上述した実施の形態にしたがって製造した。
比較例1の窒化物半導体結晶は、基本的には本発明例1と同様に製造したが、坩堝101を構成する材料がカーボンであった点および被覆管110を備えていなかった点において異なっていた。
比較例2の窒化物半導体結晶は、基本的には本発明例1と同様に製造したが、坩堝101を構成する材料がTaC(炭化タンタル)であった点および被覆管110を備えていなかった点において異なっていた。
本発明例1、比較例1および2のAlN結晶について、SIMSを用いて不純物濃度としてSi濃度、C濃度、およびO濃度を測定した。その結果を下記の表1に示す。
表1に示すように、Cを含まず、かつ原料17の融点よりも高い金属よりなる坩堝101を用いて製造した本発明例1のAlN結晶では、C濃度およびSi濃度がそれぞれ1ppm以下で、不純物濃度が2ppm以下と非常に低かった。
本実施例の試料1〜3では、基本的には本発明例1の製造装置100を用いてAlN結晶を製造したが、キャリアガスとして、反応容器123内における被覆管110の内周側にN2ガスを流し、反応容器123内における被覆管110の外周側にヘリウム(He)ガス、ネオン(Ne)ガス、Arガスをそれぞれ流した点において異なっていた。
