Patent ID: 7517734

Claim:
A method of manufacturing a wafer level package, said method comprising the steps of: preparing a device wafer in which a micro device, and bonding pads connected to the micro device are formed at one surface thereof; forming via connectors extending from the bonding pads to the other surface of the device wafer; bonding a cap structure to one surface of the device wafer so as to allow the micro device to be insulated and hermetically sealed; and forming external bonding pads at the other surface of the device wafer, the external bonding pads being connected to the bonding pads through the via connectors, respectively; wherein the cap structure is prepared by a process comprising the steps of: forming a photosensitive dry film structure having a well for receiving the micro device and bonding pads, and applying a passivation layer to an outer surface of the dry film structure.
