Altera has been working TSMC since 1993
UMC used UMC for a while but recently switched to Samsung and TSMC
It is good that Tabula is dealing with both the Giant Foundries TSMC and Intel this way it will be able to have access to the latest manufacturing technology and the advantage of the experienced manufacturers. Altera and Xilinx will have to notice the presence of this small company coming up. By the way any clue about the manufacturing foundry of Altera and Xilinx products?
I don't know if that is the only thing Intel is offering, foundry wise. It may be that that is the only segment at this point that is willing to pay Intel's premium. As far as its own ramp, Intel has enough employees that I don't think a couple small foundry customers will be a distraction. However, there is some speculation that Intel is having difficulty with the 22-nm ramp, hence the delays.
