    • 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).
    • 形成了在富氧或真空环境中不需要结合工艺的传感器(10,30)。 在第一实施例中,使用端口(14),通道(15)和开口(18)来向空腔(13)提供氧化环境。 在氧化过程中,空腔(13)被密封并且消耗任何剩余的氧化环境以形成处于真空压力下的密封空腔。 在替代实施例中,在第一基板(31)中形成空腔(32)。 空腔(32)由第二基板(36)覆盖,并且在空腔(32)上方的第二基板(36)中形成开口(33,34)。 这些开口(33,34)允许氧化环境进入空腔(32)。
