摘要 | In a method for making a compound semiconductor including a substrate and a compound semiconductor layer having a lattice mismatch ratio of 2% or more relative to the substrate, the method includes a first epitaxial growth step of forming a buffer layer on the substrate, the buffer layer having a predetermined distribution of lattice mismatch ratios in the thickness direction so as to reduce strain; and a second epitaxial growth step of forming the compound semiconductor layer on the buffer layer. The first epitaxial growth step is carried out by metal organic chemical vapor deposition at a deposition temperature of 600° C. or less. |
其他摘要 | 在制造包括基板和相对于基板具有2%或更大的晶格失配率的化合物半导体层的化合物半导体的方法中,该方法包括在基板上形成缓冲层的第一外延生长步骤,缓冲层在厚度方向上具有预定的晶格失配率分布的层,以减小应变;以及在缓冲层上形成化合物半导体层的第二外延生长步骤。第一外延生长步骤通过金属有机化学气相沉积在600℃或更低的沉积温度下进行。 |
