(h) 29.8 m thick Ni and 0.2 m thick Au are electroplated consecutively, the composition is the same as step (d).
(i) Removing the exposed photo resist by soaking the glass substrate in very clean acetone, and removing the exposed seed layer by using lift-off process.
(j) Removing the photoresist between fixed plate and floating plate by soaking in very clean acetone a longer time to obtain the released inertia micro capacitive sensor.
