Abstract: Disclosed herein are IC package devices and related methods of manufacturing. In one embodiment, an package device includes first and second package substrates, and a first IC chip having at least one coupling structure formed on its active region for electrically coupling the first chip to the first substrate. The IC package also includes a second IC chip having at least one coupling structure formed on its active region for electrically coupling the second chip to the second substrate. The IC package also includes a heat spreader configured to disperse heat from the first and second chips, where the heat spreader has a first surface coupled to a backside of the first chip, and a second surface that coupled to a backside of the second chip. Thus, the backsides of the two chips are oriented towards each other. The internal heat spreader also provide support across the IC package to prevent warpage, and thus maintain coplanarity of the IC package.

Abstract: A method and system for integrally checking a chip layout dataset and a package substrate layout dataset for errors are disclosed. The package substrate layout dataset is converted from a first format into a second format in which the chip layout dataset is provided. The chip layout dataset of the second format is combined with the package substrate layout dataset of the second format into a combined dataset. The combined dataset is then checked for errors or design rule violations.
