A method (38) for packaging a microelectronic device (10) and a device (10) packaged by the method (38). The method (38) includes a step of providing (42) a first material (16) on an active surface of the microelectronic device (10). The first material (16) has a first temperature coefficient of expansion. The method (38) also includes steps of heating (46) the microelectronic device (10) and the first material (16) to a predetermined first temperature and molding (48) a second material (20) about the microelectronic device (10) and the first material (16). The second material (20) has a second temperature coefficient of expansion less than that of the first material (16). A final step of cooling (50) the first material (16), the second material (20) and the microelectronic device (10) provides a packaged microelectronic device (30).
