Abstract:
1. A method for activating a getter, comprising: forming a magnetically permeable material on a first substrate; forming a cavity disposed in the first substrate under the magnetically permeable material, wherein the cavity is devoid of solid material under a substantial portion of a surface of the magnetically permeable material; forming a first layer of getter material over the magnetically permeable material; forming a microdevice on a surface of either the first substrate or a second substrate; providing a coil which is not mechanically or electrically coupled to the first substrate; applying an RF signal to the coil; heating the magnetically permeable material by inductive coupling to the coil; and heating the getter material by thermal conduction from the magnetically permeable material, to a temperature sufficient to activate a surface of the getter material for gettering.
