    Abstract: An integrated device includes at least one MOS transistor having a plurality of cells. In each of one or more of the cells a disabling structure is provided. The disabling structure is configured to be in a non-conductive condition when the MOS transistor is switched on in response to a control voltage comprised between a threshold voltage of the MOS transistor and an intervention voltage of the disabling structure, or to be in a conductive condition otherwise. A system comprising at least one integrated device as above is also proposed. Moreover, a corresponding process for manufacturing this integrated device is proposed.

    Abstract: Embodiments are directed to high electron mobility transistor (HEMT) devices and methods. One such HEMT device includes a substrate having a first surface, and first and second heterostructures on the substrate and facing each other. Each of the first and second heterostructures includes a first semiconductor layer on the first surface of the substrate, a second semiconductor layer on the first surface of the substrate, and a two-dimensional electrode gas (2DEG) layer between the first and second semiconductor layers. A doped semiconductor layer is disposed between the first and second heterostructures, and a source contact is disposed on the first heterostructure and the second heterostructure.

    Abstract: A field effect transistor has a semiconductor layer with a top surface extending in a horizontal plane, and an active area defined in which are trench gate regions, which extend in depth with respect to the top surface and have an insulating coating layer and a conductive inner layer, and source regions, adjacent to the trench gate regions so as to form a conductive channel extending vertically. The trench gate regions have a plurality of first gate regions, which extend in length in the form of stripes through the active area along a first direction of the horizontal plane, and moreover a plurality of second gate regions, which extend in length in the form of stripes through the same active area along a second direction of the horizontal plane, orthogonal to, and crossing, the first gate regions. In particular, the first gate regions and second gate regions cross in the active area, joining with a non-zero curvature radius.
