  • Publication number: 20090051044
    Abstract: A wafer-level packaging method is shown below: providing an un-cut wafer having a front side and a back side. A plurality of cutting lines is formed on the front side of the wafer so as to define the positions of each chip module such as a wireless module. The next step is providing an extendible film attached onto the back side of the wafer. Next is dicing the wafer along the cutting line to separate each chip module and expending the extendible film so that a gap is formed between each chip module. At last, filling a packaging compound onto the front side and the lateral side of the chip module produces a packaged structure. As mentioned above, the structure is employed for protecting the external surface of the chip.

  • Publication number: 20090023244
    Abstract: A method for activating a getter at low temperature for encapsulation in a device cavity containing a microdevice comprises etching a passivation layer off the getter material while the device wafer and lid wafer are enclosed in a bonding chamber. A plasma etching process may be used, wherein by applying a large negative voltage to the lid wafer, a plasma is formed in the low pressure environment within the bonding chamber. The plasma then etches the passivation layer from the getter material, which is directly thereafter sealed within the device cavity of the microdevice, all within the etching/bonding chamber.
