Abstract:
Techniques for reducing stress in an integrated circuit wafer are disclosed. A silicon substrate may include multiple integrated circuit chips and multiple scribe regions situated between the one of the multiple integrated circuit chips. A particular scribe region includes a plurality of layers and a stress reduction structure that includes, at a particular layer of the plurality of layers, a material whose coefficient of thermal expansion of materials is greater than a coefficient of thermal expansion of the silicon wafer.

Claim (Index 14):
An apparatus, comprising:\n a silicon substrate that includes:\n a plurality of integrated circuit chips; and \n a plurality of scribe regions situated between one of the plurality of integrated circuit chips, wherein a particular scribe region of the plurality of scribe regions includes:\n a plurality of layers; \n a stress reduction structure located on at least a particular layer of the plurality of layers, wherein the stress reduction structure includes, at the particular layer, a material, wherein a collective area of the material at the particular layer is at least 40 percent of a total area of the particular scribe region, and wherein the material has a coefficient of thermal expansion that is greater than a coefficient of thermal expansion of the silicon substrate; \n a test circuit; and \n one or more mask alignment targets.
