Title:
n型電極、III族窒化物系化合物半導体素子、n型電極の製造方法、及びIII族窒化物系化合物半導体素子の製造方法
Document Type and Number:
Japanese Patent JP4023121
Kind Code:
B2
Abstract:
An object of the present invention is to obtain greater reduction in resistance between an n-electrode and an n-type layer made of a Group III nitride compound semiconductor. According to the present invention, the n-electrode is formed with a first electrode material made of at least one member selected from the group consisting of vanadium (V), titanium (Ti), zirconium (Zr) and tungsten (W), a second electrode material made of at least one member selected from the group consisting of palladium (Pd) , platinum (Pt), gold (Au), silver (Ag) and copper (Cu), and a third electrode material made of at least one member selected from the group consisting of aluminum (Al), silicon (Si) and germanium (Ge).
