1. A method of fabricating a trap, comprising:
preparing a back surface of a substrate for subsequent processing;
building, after the preparation of the back surface of the substrate, a stack of multiple layers on a top surface of the substrate, the stack of multiple layers including at least one metal layer for routing and at least one metal layer for top electrodes; and
shaping the substrate, after the stack of multiple layers is built on the top surface of the substrate, by processing the back surface of the substrate.
