Abstract:
1. A bond pad design comprising: a plurality of bond pads on a semiconductor chip, all of the bond pads of the plurality of bond pads having an elongated shape, the elongated shape having an elongated portion and a contracted portion, the elongated portion of all of the bond pads of the plurality of bond pads being oriented along a stress direction radiating from a center of the chip to a periphery thereof, the plurality of bond pads comprising: a plurality of under-bump metallurgy (UBM) layers on respective bond pads of the plurality of bond pads, wherein a ratio of a length of the elongated portion to a width of the contracted portion is constant among the bond pads of the plurality of bond pads, and the first edge of the chip is substantially perpendicular to the second edge of the chip.
