Abstract
A hermetic seal for an electronic component has a cap having a base portion with laterally extending walls. The laterally extending walls define a main chamber therebetween. A cavity is formed in the end of the laterally extending walls to define a secondary chamber and divide the end of the laterally extending walls into a first area and second area. The cap is hermetically sealed to the base at the first and second areas of the laterally extending walls so that the secondary chamber and the main chamber are separately hermetically sealed.
