  • Enhancement-mode field effect transistor having metal oxide channel layer
    Patent number: 9680030
    Abstract: An enhancement-mode n-type field effect transistor is disclosed to have a metal oxide channel layer, a gate dielectric layer, a gate electrode, a source electrode, and a drain electrode. The metal oxide channel layer has a material selected from SnO2, ITO, ZnO, SnO2 and In2O3. The metal oxide channel layer has a thickness less than a threshold value to exhibit pinch-off behavior in transfer characteristics and has a mobility trend without saturation under positive operational voltage.
    Type: Grant

  • Complementary Transistor Pair Comprising Field Effect Transistor Having Metal Oxide Channel Layer
    Publication number: 20170162570
    Abstract: A complementary transistor pair with an n-type enhancement-mode field effect transistor and a p-type field effect transistor is disclosed. The n-type enhancement-mode field effect transistor uses a metal oxide channel layer having a material selected from SnO2, ITO, ZnO, SnO2 and In2O3 while the p-type field effect transistor uses a germanium-containing channel layer.

  • Method for Fabricating Enhancement-mode Field Effect Transistor Having Metal Oxide Channel Layer
    Publication number: 20170162710
    Abstract: A method for fabricating an enhancement-mode n-type field effect transistor is disclosed. The method involves forming a metal oxide channel layer, forming a gate dielectric layer, forming a gate electrode, and forming a source electrode and a drain electrode. The metal oxide channel layer has a material selected from SnO2, ITO, ZnO, SnO2 and In2O3 with a thickness less than a threshold value. With the thickness less than the threshold value the metal oxide channel layer exhibits pinch-off behavior in transfer characteristics and has a mobility trend without saturation under positive operational voltage.
