Abstract
Abstract The I/O ports of a packaged IC includes a plurality of optical conduits in the package adjacent electro-optical transmitters and receivers throughout the die spaced from the periphery of the die. The method of assembling the die in the package includes using optical transmitters on the die to align the top of the package and the optical conduits to the die which was previously mounted in the base of the package.
