摘要:
A semiconductor device utilizing redistribution layers to couple stacked die is disclosed and may include a first semiconductor die with a first surface comprising bond pads, a second surface opposite the first surface, and sloped side surfaces between the first and second surfaces, such that a cross-section of the first die is trapezoidal in shape. 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.

摘要:
In accordance with the present invention, there is provided a CPV package which comprises a leadframe assembly, such leadframe assembly including multiple frames stacked on top of each other. A top frame of the leadframe assembly provides the electrical interconnect between the top or front surface of the receiver die and the bypass diode required to complete the circuit. The top frame also provides hook up wire interconnect pads for the completed CPV package. An exposed bottom surface of a bottom frame of the leadframe assembly defines a heat spreader which assists in thermal management. The fabrication of the CPV package to include multiple frames stacked on top of each other provides high thermal dissipation and high voltage isolation, while at the same providing a high level of reliability with a comparatively low manufacturing cost.
