摘要:
An embodiment is a structure comprising a substrate, a first die, and a second die. The substrate has a first surface and a second surface opposite the first surface. The substrate has a through substrate via extending from the first surface towards the second surface. The first die is attached to the substrate, and the first die is coupled to the first surface of the substrate. The second die is attached to the substrate, and the second die is coupled to the first surface of the substrate. A first distance is between a first edge of the first die and a first edge of the second die, and the first distance is in a direction parallel to the first surface of the substrate. The first distance is equal to or less than 200 micrometers.

摘要:
A method includes bonding a first and a second package component on a top surface of a third package component, and dispensing a polymer. The polymer includes a first portion in a space between the first and the third package components, a second portion in a space between the second and the third package components, and a third portion in a gap between the first and the second package components. A curing step is then performed on the polymer. After the curing step, the third portion of the polymer is sawed to form a trench between the first and the second package components.
摘要:
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.
