1. A packaged chip, comprising:
- a chip having a front surface, an active region at the front surface and a conductive pad at the front surface conductively connected to the active region;
a packaging layer having an inner surface confronting the active region of the chip, the inner surface spaced from at least a portion of the active region to define a gap, the packaging layer having an outer surface remote from the inner surface and a plurality of edge surfaces extending away from the outer surface;
a conductive interconnect extending from the conductive pad along at least one of the edge surfaces and along the outer surface.

Abstract
An integrally packaged integrated circuit device including an integrated circuit die including a crystalline substrate having first and second generally planar surfaces and edge surfaces and an active surface formed on the first generally planar surface, at least one chip scale packaging layer formed over the active surface and at least one electrical contact formed over the at least one chip scale packaging layer, the at least one electrical contact being connected to circuitry on the active surface by at least one pad formed on the first generally planar surface.

9. A method of fabricating a plurality of packaged chips, comprising:
-
a) assembling a device wafer including a plurality of chips having front surfaces with a packaging layer overlying the front surfaces, each chip including an active region at the front surface and at least one conductive pad at the front surface conductively connected to the active region, the packaging layer having a inner surface confronting the active region, the inner surface spaced from at least a portion of the active region to define a gap, the packaging layer having an outer surface remote from the inner surface and a plurality of edge surfaces extending away from the outer surface; b) after step a), forming conductive interconnects to the chips, each conductive interconnect including a contact at the outer surface conductively interconnected to the at least one conductive pad of one of the chips by a conductor extending along a wall of at least one channel in the packaging layer; and c) severing the device wafer along dicing lanes into a plurality of packaged chips. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
