A method for a semiconductor device utilizing redistribution layers to couple stacked die is disclosed and may include bonding a first semiconductor die to a second semiconductor die, the first semiconductor die having a first surface comprising bond pads, a second surface opposite the first surface that is bonded to a first surface of the second semiconductor die, and sloped sides surfaces between the first and second surfaces of the first semiconductor die, such that a cross-section of the first semiconductor die is trapezoidal in shape. A passivation layer may be formed on the first surface and sloped side surfaces of the first semiconductor die and the first surface of the second semiconductor die. A redistribution layer may be formed on the passivation layer formed on the first surface and sloped side surfaces of the first semiconductor die and the first surface of the second semiconductor die.

A second semiconductor die with a first surface may be bonded to the second surface of the first die, wherein the first surface of the second die may comprise bond pads. A passivation layer may be formed on the first surface and sloped side surfaces of the first die and the first surface of the second die. A redistribution layer may be formed on the passivation layer, electrically coupling bond pads on the first and second die. A conductive pillar may extend from a bond pad on the second die to the second redistribution layer.
