Abstract:
A gallium nitride based semiconductor device includes a silicon-based layer doped simultaneously with boron (B) and germanium (Ge) at a relatively high concentration, a buffer layer on the silicon-based layer, and a nitride stack on the buffer layer. A doping concentration of boron (B) and germanium (Ge) may be higher than 1×1019/cm3.
Abstract:
Provided are a low-defect semiconductor device and a method of manufacturing the same. The method includes forming a buffer layer on a silicon substrate, forming an interface control layer on the buffer layer under a first growth condition, and forming a nitride stack on the interface control layer under a second growth condition different from the first growth condition.
Abstract:
A semiconductor buffer structure may include a silicon substrate and a buffer layer that is formed on the silicon substrate. The buffer layer may include a first layer, a second layer formed on the first layer, and a third layer formed on the second layer. The first layer may include AlxInyGa1-x-yN (0≦x≦1, 0≦y≦1, 0≦x+y≦1) and have a lattice constant LP1 that is smaller than a lattice constant LP0 of the silicon substrate. The second layer may include AlxInyGa1-x-yN (0≦x
