Contrary to rumors the company did not just barely achieve the the 100 nm target or the 100 nm weren't good enough, but, due to Chris, POET did much better than 100 nm.
They are now pushing to large scale manufacturing capability which is available in the shape of all the "old" (7 yeras) 45 nm fabs. You can get them for cheap and with POET turn them into big profit centers. POET is pushing for 40 nm and they have partners to help them.
