20090134957 | Film bulk acoustic resonator package and method for manufacturing the same - A film bulky acoustic resonator (FBAR) package and a method for manufacturing the package are provided. A top surface of a FBAR on a substrate is entirely covered with a cap and a signal line connected to an external circuit unit is directly attached to a bonding pad of the FBAR through a substrate via-hole formed through the substrate. Since the signal line connected to the external circuit unit is directly attached to the bonding pad of the FBAR through the substrate via-hole formed through the substrate, a process for attaining a signal line connection space of the external circuit unit can be omitted. Therefore, an overall working process can be simplified and the manufacturing cost can be reduced, while improving the production yield. Furthermore, a size of the FBAR can be remarkably reduced. In addition, as described above, when the signal line connected to the external circuit unit is directly attached to the boding pad through a bottom of the substrate, a length of the signal line can be minimized and thus the deterioration of the FBAR, which may be caused during a wafer level packaging process, can be reduced. | 05-28-2009 |
