First Claim
Patent Images
1. An integrated circuit die comprising:
- a plurality of bond pads; and
a die passivation layer comprising polymer and having a plurality of differently sized openings exposing a plurality of the bond pads, positions of the differently sized openings distributed asymmetrically relative to an entire upper surface of the integrated circuit die in a top down view, wherein sizes of the differently sized openings are measured horizontally at an upper surface of the die passivation layer.

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.
