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.
