Claim Text:
1. A method for fabricating a MEMS (micro-electro-mechanical-system) structure including a proof mass apparatus, the method comprising: providing a thickness of silicon material coupled to at least one flexible element, the thickness of silicon material being configured to move in one or more spatial directions about the flexible element(s); forming one or more stress isolation regions in thickness of silicon material in a vicinity of the flexible element; forming a plurality of recessed regions in respective spatial regions of the thickness of silicon material adjacent the stress isolation regions; forming a glue material within each of the recessed regions; and forming a plug material overlying each of the recessed regions; wherein a proof mass is configured from at least the plug material provided in each of the plug regions in the thickness of silicon material.
