Abstract

A transistor structure with a multi-layer field plate and related methods are disclosed. The transistor structure includes a dielectric layer that has a thinner portion over a first doped well and a second doped well, and a thicker portion adjacent the thinner portion and over the second doped well. The thicker portion has a height greater than the thinner portion above the doped wells. The transistor includes a first gate structure on the thinner portion and a field plate on the thicker portion of the dielectric layer.
