Contact pad for semiconductor device
First Claim
1. A device comprising:
- a die;
a molding compound along sidewalls of the die;
contact pads over the die and the molding compound; and
dummy pad features, each of the dummy pad features being adjacent a corresponding one of the contact pads, each of the dummy pad features being electrically disconnected from the corresponding one of the contact pads, wherein no other conductive material is interposed between each dummy pad feature and the corresponding one of the contact pads.

Abstract
A device and method of manufacture is provided that utilize a dummy pad feature adjacent contact pads. The contact pads may be contact pads in an integrated fan-out package in which a molding compound is placed along sidewalls of a die and the contact pads extend over the die and the molding compound. The contact pads are electrically coupled to the die using one or more redistribution layers. The dummy pad features are electrically isolated from the contact pads. In some embodiments, the dummy pad features partially encircle the contact pads and are located in a corner region of the molding compound, a corner region of the die, and/or an interface region between an edge of the die and the molding compound.
