Abstract
A microfabricated device includes a substrate having a device layer and substantially filled, isolating trenches; a doped region of material formed by photolithographically defining a region for selective doping of said device layer, selectively doping said region, and thermally diffusing said dopant; circuits on said device layer formed using a substantially standard circuit technology; and at least one structure trench in the substrate which completes the definition of electrically isolated micromechanical structural elements.
