Abstract
A method for fabricating a multiple MEMS device. A semiconductor substrate having a first and second MEMS device, and an encapsulation wafer with a first cavity and a second cavity, which includes at least one channel, can be provided. The first MEMS can be encapsulated within the first cavity and the second MEMS device can be encapsulated within the second cavity. These devices can be encapsulated within a provided first encapsulation environment at a first air pressure, encapsulating the first MEMS device within the first cavity at the first air pressure. The second MEMS device within the second cavity can then be subjected to a provided second encapsulating environment at a second air pressure via the channel of the second cavity.
