Methods of manufacturing an integrated circuit having stress tuning layer

Warpage and breakage of integrated circuit substrates is reduced by compensating for the stress imposed on the substrate by thin films formed on a surface of the substrate. Particularly advantageous for substrates having a thickness substantially less than about 150 μm, a stress-tuning layer is formed on a surface of the substrate to substantially offset or balance stress in the substrate which would otherwise cause the substrate to bend. The substrate includes a plurality of bonding pads on a first surface for electrical connection to other component.
