    摘要: Microelectronic imagers with prefabricated housings and methods of packaging microelectronic imagers are disclosed herein. In one embodiment, a microelectronic imager can include a microelectronic die, an image sensor, and an integrated circuit operatively coupled to the integrated circuit. The microelectronic imager also includes an optic unit having an optic member. The microelectronic imager further includes a prefabricated housing having a first mounting site and a second mounting site. The die is seated within the housing at the first mounting site and the optics unit is seated within the housing at the second mounting site in a fixed, preset position in which the optic member is situated at a desired location relative to the image sensor.

    摘要: Separating and coating semiconductor dice at the wafer level to form individual chip-scale packages. In one embodiment, channels are formed in the active surface of a wafer to expose side surfaces of semiconductor dice. The surfaces of the channels are then etched to remove defects resulting from cutting. A first protective coating is deposited to seal the wafer active surface and the exposed side surfaces of each semiconductor die. Finally, the wafer is singulated along the channels to provide a plurality of individual chip-scale packages. Alternatively, material is removed from the back side of the wafer to expose the channels, and a second protective coating is applied to provide completely sealed chip-scale packages. Portions of the first protective coating may also be formed to project from the channels to anchor the second protective coating in place. In another embodiment, the first protective coating is formed without forming channels in the active surface of the wafer, and then channels are formed in the back side of the wafer.

    摘要: Microfeature workpieces having alloyed conductive structures, and associated methods are disclosed. A method in accordance with one embodiment includes applying a volume of material to a target location of a microfeature workpiece, with the volume of material including at least a first metallic constituent. The method can further include elevating a temperature of the volume of material while the volume of material is applied to the microfeature workpiece to alloy the first metallic constituent and a second metallic constituent so that the second metallic constituent is distributed generally throughout the volume of material. In further particular embodiments, the second metallic constituent can be drawn from an adjacent structure, for example, a bond pad or the wall of a via in which the volume of material is positioned.
