Claim:
1. A microelectromechanical systems (MEMS) structure comprising: a first substrate with cavities, bonded to a second substrate, that forms a plurality of hermetically sealed enclosures of at least two types comprising at least a first hermetically sealed enclosure and a second hermetically sealed enclosure, wherein each of the plurality of hermetically sealed enclosures is defined by the first substrate, the second substrate, and a seal-ring material, wherein a first enclosure type of the first hermetically sealed enclosure or the second hermetically sealed enclosure further includes a gettering element configured to decrease cavity pressure in the first enclosure type or an outgassing element configured to increase cavity pressure in the first enclosure type, and wherein the first enclosure type further includes at least one heater integrated into the second substrate adjacent to the gettering element or the outgassing element configured to adjust the temperature of the gettering element or the outgassing element and configured to adjust a gas composition by temperature specific selective absorption or desorption of the gettering element or the outgassing element, respectively, in the first enclosure type of the first hermetically sealed enclosure or the second hermetically sealed enclosure.
