1. A microdevice, comprising:
- a plurality of layers of successively deposited materials, wherein formation of each layer comprises;
a. selective deposition of at least a first material; and
b. deposition of at least a second material, which is different from the first material;
c. removal of any first and second material that extend beyond a desired boundary level of the layer;
wherein each successively formed layer is simultaneously deposited and adhered to a previously formed layer;
wherein at least a portion of one of the first or second materials from a plurality of the layers is removed via an etching operation after formation of the plurality of layers wherein the etching operation removes the one of the first or second materials without substantially removing the other of the first or second material; and
wherein a structure resulting from the formation and the removal provides at least one structure that can function as an accelerometer.
