Abstract:
1. A bonded structure comprising a first substrate, a second substrate, a polymeric ring, and a ring-shaped cavity encapsulated by said first substrate, said second substrate, and said polymeric ring, wherein said first substrate includes a first flat surface, a first non-flat surface that adjoins said first flat surface at an entirety of a periphery of said first flat surface, and another surface of said first substrate that overlies said first flat surface and adjoined to a periphery of said first non-flat surface, wherein said second substrate includes a second flat surface, a second non-flat surface that adjoins said second flat surface at an entirety of a periphery of said second flat interface, and another surface of said second substrate that underlies said second flat surface and adjoined to a periphery of said second non-flat surface, wherein an entirety of an area at which said first flat surface coincides with said second flat surface constitutes an intersubstrate interface at which a bondable material within said first substrate is bonded to a bondable material within said second substrate, and wherein said polymeric ring is in direct contact with said first non-flat surface at a first polymer-to-non-polymer interface and said second non-flat surface at a second polymer-to-non-polymer interface.
