Abstract: A method for sealing cavities in micro-electronic/-mechanical system (MEMS) devices to provide a controlled atmosphere within the sealed cavity includes providing a semiconductor substrate on which a template is provided on a localized area of the substrate. The template defines the interior shape of the cavity. Holes are made so as to enable venting of the cavity to provide a desired atmosphere to enter into the cavity through the hole. Finally, a sealing material is provided in the hole to seal the cavity. The sealing can be made by compression and/or melting of the sealing material.
