December issue of IEEE Spectrum revisits the controversial story of CCD invention:
It's easy to see why the Nobel committee went with Boyle and Smith. The CCD is synonymous with its only practical application: imaging. And according to many authoritative sources, Boyle and Smith invented the CCD. But had the Nobel nominators looked one step down the chain of invention, things might have been different.
Carlo Séquin, now a professor of electrical engineering and computer science at the University of California, Berkeley, says: "If the fundamental concept was the charge-transfer principle, then that goes to Boyle and Smith, and maybe Gene Gordon." If it's the invention of a practical CCD imager, "credit would go to Mike Tompsett, and possibly Gilbert Amelio," he says. (Amelio led commercial CCD development at Fairchild Semiconductor.)
There are also references to Smith, Boyle and Gordon versions of the CCD invention story.
