HP's ''NMOS II'' process as the name implied was a second generation nMOD process which was a shrink of their previous generation [[7 µm]] nMOS also developed by [[HP]]'s Loveland Division. The shrink was done in the hope they could double the speed while doubling density. Loveland went on on to create a third and final process, the ''NMOS III'' using a [[1.5 µm process]]. While they succeeded in doubling the density and more than ten-folding the speed, the complexity of the chip still required them to fabricate it on 3 seperate dies and package them together.

The 5μm lithography process was the semiconductor process technology used by some semiconductor companies during the mid 1970s. This process was later superseded by 3 µm, 2 µm, and 1.5 µm processes.

Industry

HP's NMOS II was a second generation nMOD process which was a shrink of their previous generation 7 µm nMOS also developed by HP's Loveland Division. The shrink was done in the hope they could double the speed while doubling density. Loveland went on on to create a third and final process, the NMOS III using a 1.5 µm process. While they succeeded in doubling the density and more than ten-folding the speed, the complexity of the chip still required them to fabricate it on 3 separate dies and package them together. Intel introduced their 2116 in 1976, the first 16 Kib DRAM which was also implemented using 5 micron design rules.
