Abstract
A substrate is formed from a core substrate of flexible, low-temeprature co-fireable ceramic tape and an outer substrate of ceramic tape having apertures for receiving integrated circuits (ICs) therein. The substrate is heated the form a rigid body which then mounts the ICs. The rigid body and ICs are covered or at least partially covered with an insulating glass and heated to a temperature that fuses the glass but does not harm the ICs. The resulting structure hermetically seals the ICs in a single substrate that is insensitive to acceleration forces.
