Selenium is a chemical element with the symbol Se and atomic number 34. It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. It rarely occurs in its elemental state or as pure ore compounds in the Earth's crust. Selenium – from Ancient Greek σελήνη (selḗnē) "Moon" – was discovered in 1817 by Jöns Jacob Berzelius, who noted the similarity of the new element to the previously discovered tellurium (named for the Earth).
Oxide semiconductor device and surface treatment method of oxide semiconductor
InactiveUS20090166616A1Effectively suppressing the threshold potential shift and occurrence of leak currentPhysical property is lessSolid-state devicesSemiconductor/solid-state device manufacturingGas phaseThreshold potential
Oxygen defects formed at the boundary between the zinc oxide type oxide semiconductor and the gate insulator are terminated by a surface treatment using sulfur or selenium as an oxygen group element or a compound thereof, the oxygen group element scarcely occurring physical property value change. Sulfur or selenium atoms effectively substitute oxygen defects to prevent occurrence of electron supplemental sites by merely applying a gas phase or liquid phase treatment to an oxide semiconductor or gate insulator with no remarkable change on the manufacturing process. As a result, this can attain the suppression of the threshold potential shift and the leak current in the characteristics of a thin film transistor.
