1. A method of manufacturing a device, comprising:
providing a substrate having a first specified area;
attaching a cap to a first surface of the substrate, the cap covering the first specified area, having a retaining structure, formed in a first surface of the cap; and
inserting an electrolyte through a first hole formed in the cap;
wherein the retaining structure is configured to retain the electrolyte in alignment with the first specified area,
wherein the cap defining a first recess and wherein the retaining structure including at least one protrusion formed on and extending away from the first surface of the cap defining a second recess including a portion of the first surface of the substrate within the first recess so that the retaining structure is configured to restrict movement of the electrolyte within a portion of the first specified area defined by the second recess,
wherein the first hole is located inside the second recess;
forming a second hole inside the first recess but outside the second recess; and
venting excess electrolyte using the second hole.
