450 millimetre wafers are still a pipe dream

The chief technology officer of TSMC, Jack Sun, outlined the plans the foundry has for moving to 450 millimetre wafers. There appear to be some problems.

One of the problems is the sheer cost required to create a 15 nanometre process on a 450 millimetre and it’s not pretty. The estimate is that such a fab will cost maybe as much as $20 billion and it appears the only companies to have agreed on such a plan are Intel, Samsung and TSMC.

The story is too old to be commented.
