Abstract:
1. A microelectromechanical device, comprising: at least one optical signal conduit disposed on a substrate; at least one cap bonding pad disposed on the substrate and over a portion of the at least one optical signal conduit, the at least one cap bonding pad being formed of a polymer free material, the at least one cap bonding pad including a planarized top surface, the at least one cap bonding pad partially defining a cavity; and a cap bonded to the at least one cap bonding pad, and covering the cavity thereby forming a capped area having a controlled environment; and an adhesive disposed on a sidewall of the at least one cap bonding pad and on a sidewall of the cap, wherein the at least one optical signal conduit extends from outside the capped area to inside the controlled environment of the capped area.
