The invention includes a method of forming a planarized surface over a semiconductor substrate. Metadata is aggregated that is related to one or more participant electronic devices and a presenter electronic device that communicate with each other in the web conference. The method can be used in conjunction with existing VPN and proxy solutions, but provides distinct additional functionality, particularly suited to corporate needs. The resulting duplex nucleic acids comprise a set of sequence tags, comprising an addressable portion, a target nucleic portion and a portion of the nucleic acid bridge. In an embodiment, handles are provided on the cover member to facilitate handling and storage of the device. A second transparent conductive layer is formed on the base.
