发明名称 Controlling warping in integrated circuit devices
摘要 Techniques for integrated circuit device fabrication are provided. In one aspect, an integrated circuit device comprises a base, at least one die attached to the base, and a counterbalancing layer on at least a portion of at least one side of the base adapted to compensate for at least a portion of a thermal expansion difference existing between the base and the die. In another aspect, warping of an integrated circuit device comprising at least one die attached to a base is controlled by applying a counterbalancing layer to at least a portion of at least one side of the base adapted to compensate for at least a portion of a thermal expansion difference existing between the base and the die.
