ABSTRACT:
A moisture getter, which is a material capable of absorbing moisture, is painted within the cap of an integrated circuit package prior to sealing. The package is then heated to the high sealing temperature necessary to provide sealing without affecting the getter material. The getter material is formed from a family of materials which is capable of withstanding the high temperature of the sealing process without degradation and which can absorb a large amount of water after exposure to sealing temperatures.
