1. A process for manufacturing a device for use in the production of a microdevice including the steps of:
creating a support device by deposing discrete deposits of contaminant removing material on a base layer of a material selected from the group consisting of glasses, ceramics, semiconductors and metals, wherein said contaminant removing material is selected among the group of materials consisting of getter materials and drier materials;
covering said contaminant removing material by a manufacturing layer, wherein said manufacturing layer is a substrate layer which may be used in the manufacture of said microdevice;
removing selected materials in said manufacturing layer creating a passage in said manufacturing layer, such that said contaminant removing material is exposed to atmosphere, wherein said passages create; and
attaching said support device such that it covers operational parts of said microdevice and a seal is created at the periphery of said cavity by said support device and said microdevice, whereby said operational parts are placed in said cavity from removed layer of manufacturing material.
