  • Semiconductor device with schottky contact and method for forming the same
    Publication number: 20010034116
    Abstract: Method for forming a Schottky contact in a semiconductor device includes a step of preparing an n type GaN group compound semiconductor layer, such as AlxGa1-xN and InxGa1-xN. At least one metal layer including a ruthenium component layer is formed on the n type GaN group compound semiconductor layer as a rectifying junction metal. The rectifying junction metal may be used as a gate of a field effect transistor, or an electrode of a Schottky diode. The ruthenium oxide has a low cost, is stable to heat and chemical, and has excellent electric characteristics. The application of the ruthenium oxide to the rectifying junction metal enhances performances, such as UV ray detection, of electronic devices and optical devices operable at an elevated temperature.
