CHMOS

[2] CHMOS was used in the Intel 80C51BH, a new version of their standard MCS-51 microcontroller.

[4][5] CHMOS III-E was used for the 12.5 MHz Intel 80C186 microprocessor.

[7] CHMOS IV (H stands for High Speed) used 1.0 μm lithography.

Many versions of the Intel 80486 were made in 1.0 μm CHMOS IV.

[8] CHMOS V used 0.8 μm lithography and 3 metal layers, and was used in later versions of the 80386, 80486, and i860.
