Abstract
A method for assembling a hermetically sealed package to contain a MEMS die and the hermetically sealed package are presented. The method includes selectively applying a glass mixture to a dome. The dome is heated to a first temperature sufficient to flow the glass mixture. The dome is pressed into contact with a carrier containing the MEMS device, the pressing being maintained at a pressure and for a temporal interval sufficient to flow the glass mixture onto the carrier. The dome is cooled while maintaining contact with the carrier, to a second temperature sufficient to allow the glass mixture to harden into a glass frit thereby to seal the carrier to the dome. The glass frit has a seal width.
