Paul, Do not the new cassettes that hold the wafers allow for piecemeal upgrades? An 8" component can have a 300MM replacement installed and then they can test it and use it with the smaller 8" wafers and then replace the next one and so on until they have them all upgraded to 300MM and working fine and then place 300 MM wafers into them. Was not cassettes invented for just this reason? To break the continous flow into a semi batch mode? In addition they can also use more parallelism so instead of 5 production lines they can have free standing machines with cassette carrybots feeding them. So they may have 4 of one machine 8 of another etc becuse the machine they have four of has twice the throughput of the machine they have 8 of. That way when a single machine is down the line works around it and often has enough extra capacity to absorb the falloff from the down machine? Bill
