Power devices with super junctions and associated methods of manufacturing are disclosed herein. In one embodiment, a method for forming a power device includes forming an epitaxial layer on a substrate material and forming a trench in the epitaxial layer. The trench has a first sidewall, a second sidewall, and a bottom between the first and second sidewalls. The method also includes forming an insulation material on at least one of the first and second sidewalls of the trench and diffusing a dopant into the epitaxial layer via at least one of the first and second sidewalls of the trench via the insulation material.
