DMILL, a mixed analog-digital radiation-hard BICMOS technology for high energy physics electronics.

High Energy Physics experiments under preparation at CERN (Geneva, Switzerland) with the future LHC (Large Hadron collider) require a fast, low noise, very rad-hard, mixed analog-digital microelectronics VLSI technology. Readout electronics designed using such a technology for the central parts of the LHC particle detectors must withstand more than 10 Mrad (SiO2) and 10(14) neutrons/cm(2) over 10 years of operation. We present here recent results obtained with a new rad-hard analog-digital technology called DMILL(1) [1-8], which monolithically integrates NPN bipolar, CMOS and P-JFET transistors, and which has been specifically developed to fulfill the severe constraints of LHC detector readout circuits.
