摘要: A sensor (10,30) is formed that does not require a bonding process in an oxygen rich or vacuum ambient. In a first embodiment, a port (14), a channel (15) and an opening (18) are used to provide an oxidizing ambient to a cavity (13). During an oxidation process, the cavity (13) is sealed and any remaining oxidizing ambient is consumed to form a sealed cavity that is under a vacuum pressure. In an alternate embodiment, a cavity (32) is formed in a first substrate (31). The cavity (32) is covered by a second substrate (36) and an opening (33,34) is formed in the second substrate (36) above the cavity (32). These openings (33,34) allow an oxidizing ambient to enter the cavity (32).
