Abstract:
A die having a ledge along a sidewall, and a method of forming the die, is provided. A method of packaging the die is also provided. A substrate, such as a processed wafer, is diced by forming a first notch having a first width, and then forming a second notch within the first notch such that the second notch has a second width less than the first width. The second notch extends through the substrate, thereby dicing the substrate. The difference in widths between the first width and the second width results in a ledge along the sidewalls of the dice. The dice may be placed on a substrate, e.g., an interposer, and underfill placed between the dice and the substrate. The ledge prevents or reduces the distance the underfill is drawn up between adjacent dice. A molding compound may be formed over the substrate.
