Claim 14:
15. The method of claim 14 further comprising:
defining a plurality of test locations on the device layer;
defining a plurality of test strain gages, wherein each of the plurality of test strain gages is a strain gage of the first plurality thereof located at a different test location of the plurality of test locations; and
for each test strain gage of the plurality thereof, determining at least one parameter that is selected from the group consisting of:
(i) gage resistance;
(ii) thermal coefficient of resistance (TCR);
(iii) a difference between a measured gage resistance and an expected gage resistance at a first temperature, wherein the expected gage resistance is based on at least one lateral dimension of the body of the test strain gage and a resistivity measured at the test location of the test strain gage;
(iv) average gage resistance of a plurality of nearest-neighbor test gages in the plurality of test strain gages; and
(v) maximum resistance deviation from an average gage resistance at a first temperature of the plurality of nearest-neighbor test gages.
