Abstract: A method of fabrication of micromechanical devices enables the production of large area micromechanical transducer structures which are symmetric, stress balanced structures relatively devoid of geometric distortions. Micromechanical transducer structures are fabricated implementing processes and physical characteristics which overcome the unbalanced stresses occurring in high concentration diffusion planar structures that cause problematic geometric distortions that restrict physical size. Large increases in the practical size of micromechanical devices which may be fabricated are achieved while permitting greater depths of structural features, without the resultant concentration and stress distortions. Multilevel, balanced stress structures can be created which are of varying geometries at each level to produce a "sculpted" structure.
