    摘要: A method of making an electronic device with a redistribution layer includes providing an electronic device having a first pattern of contact areas, and forming a redistribution layer on a temporary substrate. The temporary substrate has a second pattern of contact areas matching the first pattern of contact areas, and a third pattern of contact areas different than the second pattern of contact areas. The second pattern of contact areas is coupled to the third pattern of contact areas through a plurality of stacked conductive and insulating layers. The first pattern of contact areas is coupled to the second pattern of contact areas on the transferrable redistribution layer. The temporary substrate is then removed to thereby form a redistributed electronic device.

    摘要: A method of making redistributed electronic devices that includes providing a wafer having a plurality of electronic devices, each electronic device having a pattern of contact areas forming die pads. The method also includes forming redistribution layers on a temporary substrate having a pattern of contact areas forming wafer bonding pads matching the die pads and a pattern of contact areas forming redistributed pads different than the wafer bonding pads, the wafer bonding pads are coupled to the redistributed pads through a plurality of stacked conductive and insulating layers. The die pads are coupled to the wafer bonding pads, and the temporary substrate is removed. The wafer and redistribution layers are then divided into a plurality of redistributed electronic devices.

    摘要: A method of making a multi-chip module may include forming an interconnect layer stack on a sacrificial substrate. The interconnect layer stack may include patterned electrical conductor layers and a dielectric layer between adjacent patterned electrical conductor layers. The method may further include electrically coupling a first integrated circuit (IC) die in a flip chip arrangement to an uppermost patterned electrical conductor layer, and forming a first underfill dielectric layer between the first IC die and adjacent portions of the interconnect layer stack. The method further may include removing the sacrificial substrate to expose a lowermost patterned electrical conductor layer, and electrically coupling at a second integrated circuit die in a flip chip arrangement to the lowermost patterned electrical conductor layer. Still further, the method may include forming a second underfill dielectric layer between the second IC die and adjacent portions of the interconnect layer stack.

    摘要: A method of processing a wafer includes establishing a fine of symmetry defining left and right die areas on a front side of the wafer and left and right die areas on a back side. A first mask is used to form a first interconnection layer on the left and right die areas comprising a first portion on the left die area and second portion different than the first portion on the right die area. A second mask is used to form a second interconnection layer on the left and right die areas comprising a third portion on the left die area and fourth portion different than the third portion on the right die area. The first mask is reused to form a third interconnection layer on the left and right die areas on a back side, and the second mask to form a fourth interconnection layer on the left and right die areas on a back side.
