Abstract:
The present invention relates generally to flip chip technology and more particularly, to a method and structure for fabricating a mechanically anchored controlled collapse chip connection (C4) pad on a semiconductor structure. In an embodiment, a method is disclosed that may include forming a bonding pad having one or more anchor regions that extend into a semiconductor structure and may inhibit the bonding pad from physically separating from the TSV during temperature fluctuations.
