Process Technology[edit]
- See also: 0.35 µm process
Alpha 21264 was manufactured on a 0.35 µm process at DEC's own Hudson foundry. The process had a 0.35 µm drawn gate length and 0.25 µm effective channel length. The CMOS process had 3 metal layers. The chip allowed for a supply voltage of up to 2 V in order to limit the chips to a power limit of 72 W, although it was actually designed to reliably operate at up to 2.5 V.
