By the way, it occurred to me that as features become smaller and smaller the importance of ionizing effects post production may become more and more important, and i wonder if the march to smaller features might not be halted by such stupid things like "cosmic radiation".

Hi Zeev,
This is true, but it's not even just post-production effects that are important. As feature sizes get smaller, things like discharges of charge buildups on insulators during plasma etching can end up destroying devices. Process steps like Reactive Ion Etching may have to be modified or replaced before much smaller feature sizes can be successfully manufactured.
