Abstract
A MEMS package is provided. The MEMS package includes a metallization layer, a planarization structure, a MEMS device structure, a cap structure and a pressure adjustment element. The planarization structure has an inner sidewall defining a first cavity exposing the metallization layer. The MEMS device structure is bonded to the planarization structure. The MEMS device structure includes a movable element over the first cavity. The cap structure is bonded to the MEMS device structure and has an inner sidewall defining a second cavity facing the movable element. The pressure adjustment element is disposed in the second cavity.
