The 0.18 micron semiconductor technology node achieved widespread use in 1999. This is the date when 180nm was popularized as a logic or digital-only process. By the mid-2000’s, foundries added mixed-signal capabilities and performance to this process node. The 180nm process node will be a very popular node for mixed signal applications well into the 2020s.
Triad sees 180nm as a very popular mixed signal ASIC node for the next several years. 180nm offers good logic gate density while supporting thick-oxide analog features. In fact, a good mixed signal 0.18-micron process node will combine 1.8V thin oxide digital capabilities with 3.3V / 5V thick oxide analog capabilities. This combination good logic density combined with the voltage headroom of a 3.3V or 5V process is well suited to real-world mixed signal applications. Triad offers 180nm mixed signal process access at AMS, MagnaChip, TowerJazz, IBM and TSMC. High voltage options are available on these 180nm process nodes as well.
