Cost-effective fab-capacity expansion

Compared to fab expansion via new cleanroom construction, a SMIF upgrade may prove to be the lowest risk with the shortest time to project completion By Chris Humphreys & S. Peter Hansen With the semiconductor industry upturns and downturns occurring more frequently, capacity planning becomes a difficult task. Greenfield expansions can take 18 months or more to put capacity in place, and fab expansions can take up to 12 months.…

Energy conservation: Cost is not the real issue

For some time now we've been concerned about energy conservation in semiconductor manufacturing cleanrooms. Papers have been written, seminars have been conducted, consultants have proliferated and engineers have gone back to drawing boards where they've produced solutions-some quite innovative and others rather exotic. by Mike Fitzpatrick Click here to enlarge image We have even reduced the airflow in our cleanrooms, taking our most widely used process fluid-clean air-and diminished its…
