Miniature microdevice package and process for making thereof

A miniature microdevice package comprising:

• a miniature frame substrate made of a material selected from the group including:
• metal, ceramic having the properties of no outgassing, low porosity, and dimensional stability, and a combination of metal and ceramic having the properties of no outgassing, low porosity and dimensional stability, the miniature frame substrate having a spacer delimiting a hollow, the spacer being shaped in the miniature frame substrate;
• and
• a microdevice die having a microdevice substrate, a microdevice integrated on the microdevice substrate, bonding pads integrated on the microdevice substrate, and electrical conductors integrated in the microdevice substrate for electrically connecting the bonding pads with the microdevice, the microdevice die being mounted on the spacer to form a chamber, the microdevice being located within the chamber, the bonding pads being located outside of the chamber.
