A few process shrinks ago, alpha particle= effects were becoming worryingly intrusive and everybody was concerned how= much smaller features on ICs could actually be pushed. I recall when the 64kb DRAMs first appeared and alpha particle hits were suddenly a critical issue - the doomsayers were claiming DRAM cells couldn't be shrunk any further. I suspect moving from CERDIP to plastic packages and adding suitable coatings to stop alpha particles helped. In any case, things have shrunk by about 5 orders of magnitude and no-one mentions alpha particles any more. --=20 Peter Jeremy --0OAP2g/MAC+5xKAE Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJV/PxXXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRFRUIyOTg2QzMwNjcxRTc0RTY1QzIyN0Ux NkE1OTdBMEU0QTIwQjM0AAoJEBall6Dkogs0ZE4QAIXRbIB03xeKKbjsiWNy/hkE Zr+9ZbKwZiuPq8cdxiIgjiYnZ/tt3kzhpJGRtbV5XkoX0mqmGedMG2alyVSrgASb m4egXlK1PLQzC6Wap2aeOfAE2kPd/YwCM6eSFBwjJnzYe2moJbjgensVzUlUOhGt bzATqtLkcg1w1UmH3OqSsUnCJMIr9W6cKSs3WhcWL242Tcs1nbrzg4WY8iM9VAOu MihibUbXtDqRpbg9gkZ74qmRydJdU2gESR4kPyQ5yfl69Xveo5KPZPpAkPXXGKqD TlWTdepamuoiyvRaZyAnLt0B5eIkndLBytFgH4XXRxnFDivMGfKbIHGY4wY6IQAE 52er5a703yee9UbmdtmNq257Q1TZQDyz+ejaft5qRj6/Utwe9mC9xXKkv+TMpBSU NthSfgbZ2fGYncohOfzLr/4ParrS2o9hDmrDqwrY0ywn6MTqNFlmlI3j7lTguEJ7 Dj8xrDB1EnXhs5AUUlcFKwDd1JNNESssXiPihVJiScGnbRWhK40as6Vx7qDQFIH6 kzePIK8PF1fahzxJIFSwZbQkTkUOGoU7fMVZN8CyaNiB0F9mqApvmbSPLabbvwJL UKESruon4iq7jv2LaST8D30y8b63ASnQ2xtnIj6MMyz/60/61mZbE5PLdnqbcx3U IZdCFi17hghOUtsw7FTa =GUNY -----END PGP SIGNATURE----- --0OAP2g/MAC+5xKAE--
