Patent ID: 8895370

Claim:
A method for forming an electronic device comprising: forming an epitaxial layer on a substrate; forming respective gate, source and drain areas in the epitaxial layer; forming a first metallization level adjacent the epitaxial layer defining respective gate, source and drain metallizations for the gate, source and drain areas; forming a second metallization level adjacent the first metallization level defining respective gate, source and drain terminals for the gate, source and drain metallizations; the respective gate, source and drain areas being formed as a set of modular areas extending parallel to each other, each modular area having a source area with a rectangular elongate shape, the source area perimetrically surrounded by the gate area and the drain area, the drain area being defined by first regions and second regions, the first regions of the drain area extending parallel to one another and separating adjacent one of the modular areas, and the second regions of the drain area extending parallel to one another and contacting ends of the first regions of the drain area; and forming a sinker structure extending perpendicularly to the substrate and comprising a grid of sinkers located directly below both the first regions and the second regions of the drain area.
