  • Patent number: 8563984
    Abstract: Device having reduced buffer leak on GaN substrate. In HEMT device, n-GaN (n-type GaN wafer) is used as substrate 11. Non-doped AlpGa1-pN layer with non-uniform composition p is formed on substrate 11 as buffer layer 12. On buffer layer 12, channel layer 13 of semi-insulating GaN and electron supply layer 14 of n-AlGaN are sequentially formed. In buffer layer 12, substrate connection region 121 where p=0 (GaN) is formed on lower end side, and active layer connection region 122 where value of p is also 0 (GaN) is formed on upper end side (channel layer 13 side). High Al composition region 123 where value of p is set to 1 (p=1) (AlN) is formed between substrate connection region 121 and active layer connection region 122. Resistivity of the high Al composition region 123 is highest in the buffer layer.
