Abstract
Disclosed is a method of forming an integrated circuit structure that forms lead-free connectors on a device, surrounds the lead-free connectors with a compressible film, connects the device to a carrier (the lead-free connectors electrically connect the device to the carrier), and fills the gaps between the carrier and the device with an insulating underfill.
