Claim 3:
4. The micromachined resonator of claim 3 wherein the first structure has a cross-sectional axis that is orthogonal to the first axis and wherein the impurity dopant has a maximum concentration within the first structure along the cross-sectional axis of the first structure at each surface of the first structure and a minimum concentration within the first structure at a point intermediate to surfaces of the first structure and wherein the second structure has a cross-sectional axis that is orthogonal to the second axis and wherein the impurity dopant has a maximum concentration within the second structure along the cross-sectional axis of the second structure at each surface of the second structure and a minimum concentration within the second structure at a point intermediate to surfaces of the second structure.
