Abstract
Integrated circuit dies are provide with a passivation layer having a plurality of differently sized openings exposing bond pads for bonding. The sizes of the bond pads vary in a manner that at least partially compensates for stresses during bonding, such as flip chip thermocompression bonding, due to asymmetric distribution of bond pads.
