摘要
Various embodiments of the present disclosure are directed towards an integrated chip including a capping structure over a device substrate. The device substrate includes a first microelectromechanical systems (MEMS) device and a second MEMS device laterally offset from the first MEMS device. The capping structure includes a first cavity overlying the first MEMS device and a second cavity overlying the second MEMS device. The first cavity has a first gas pressure and the second cavity has a second gas pressure different from the first cavity. An outgas layer abutting the first cavity. The outgas layer includes an outgas material having an outgas species. The outgas material is amorphous.
