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 (SiO/sub 2/) and 10/sup 14/ neutrons/cm/sup 2/ over 10 years of operation. We are presenting here recent results obtained with a new rad-hard analog-digital technology called DMILL, which monolithically integrates NPN bipolar, CMOS and P-JFET transistors, and which has been specifically developed to fulfil the severe constraints of LHC detectors readout circuits.
