IC 0.35µm ARC C35B4O1

IC ams 0.35µm CMOS Opto ARC 4 ML C35B4O1


This 0.35 CMOS-Opto process is offered in each 0.35 CMOS run (C35B4C3).
This is a ARC (Anti Reflective Coating) option.

  • Anti-Reflective Coating (ARC) allows a higher photo-sensitivity than C35B4C3.
  • P-Epi wafers for lowering current leakage in the diode (lower dark current).

The C35B4O1 is with 4 layers metal available for prototyping and low volume production.
Met. layer(s): 4
Poly layer(s): 2
Maximum die size: 2cm x 2cm
DLP Usable cells: about 300 digital cells
Available I/O: I/O cell library with digital pads is available 3V, 3V/5V, 5V with internal level shifters
Temp. range: -40° C. / +125° C.
Supply voltage: 5V or 3.3V.


High performance analog/digital process + anti-reflective coating for optical devices


Provides enhanced optical sensitivity for embedded photodiodes and high density CMOS camera products.
