Abstract
An encapsulated semiconductor device includes a device die with a semiconductor device fabricated thereon. A carrier layer opposite the device die covers the semiconductor device. A dam supports the carrier layer above the device die, the dam being located therebetween. The semiconductor device further includes a first sealant portion for attaching the dam to the device die, and a means for attaching the dam to the carrier layer. The device die, the dam, and the carrier layer form a sealed cavity enclosing the semiconductor device. A method of encapsulating semiconductor devices formed on a device wafer includes forming an assembly including a carrier wafer and a plurality of dams thereon. After the step of forming, the method attaches the plurality of dams to the device wafer to form a respective plurality of encapsulated semiconductor devices.
