bond pad
In the fabrication of chips, the chip core, called the dice, is provided with bonding points to which the microfine bonding wires of 12.5 µm to 50 µm diameter are welded during bonding. Depending on the application, the bond wires can be made of gold, silver, copper or aluminum.
The bonding points are the bonding pads. The size of the bond pads depends on the chip technology and integration density. Whereas the values used to be in the micrometer range, they are several hundred nanometers in modern integrated circuits.
