Abstract
A MEMS device comprises a first layer (), a second layer () and a third layer () sealed together. A mobile structure () in the second layer () is defined by openings () in the second layer (). In the first layer (), there is at least one first-layer cavity () with an opening towards the mobile structure () of the second layer (). In the third layer (), there is at least one third-layer cavity () with an opening towards the mobile structure () of the second layer (). Therefore, the third-layer cavity () and the second layer () define a space within the MEMS device, A getter layer () arranged on a surface of said space. The getter layer () is preferably arranged on a surface of the second layer () and in particular, the getter layer () is arranged on a static part of the second layer (). Alternatively, the MEMS device has a third-layer cavity () with at least two recesses () and the getter layer () is arranged on a surface of the recesses ().
