    Abstract: Disclosed herein are IC structures, packages, and devices assemblies that use ions or fixed charge to create field plate structures which are embedded in a dielectric material between gate and drain electrodes of a transistor. Ion- or fixed charge-based field plate structures may provide viable approaches to changing the distribution of electric field at a transistor drain to increase the breakdown voltage of a transistor without incurring the large parasitic capacitances associated with the use of metal field plates. In one aspect, an IC structure includes a transistor, a dielectric material between gate and drain electrodes of the transistor, and an ion- or fixed charge-based region within the dielectric material, between the gate and the drain electrodes. Such an ion- or fixed charge-based region realizes an ion- or fixed charge-based field plate structure. Optionally, the IC structure may include multiple ion- or fixed charge-based field plate structures.
