I recently heard SEMI saying that fab equipment is revised from -5% to -7% for 2012 and for 2013 from 17% to 13%. Still quite optimistic for 2013 but in sink with revenue predictions.

I think there is another factor at play too. Equipment spending is heavily influenced by migration to newer technology nodes. Since fewer and fewer fabs are migrating to the more advanced nodes, due to complexity and cost, there are fewer technology migrations to drive equipment spending. Even if you argue that the fewer fabs will need to buy more equipment to cover the demand, it will at least induce more fluctuation in the spending as the process migration will be more sporatic with fewer players to even out the averages.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
