Subject: Technology difference vs. system reliability
Message:
I was wondering if anyone has done long term reliability studies of "gem" emulated microcircuits. what is the mtbf for a 1.5 micron BiCmos designed IC vs. a 4-7 micron bipolar IC. What other problems ie. ESDS, Radiation Tolerance, Metal migration etc,

Reliability of the two styles of microcircuits, that is 1.5 micron technology and 4 micron technology have a historical failure rate difference of about 7 or 8 times. The old four micron technology devices show failure rates of 28 fits [failures per billion hours] for nand technology where 1.5 micron devices have a failure rate of 4 fits. This information was developed via the RACís PRISM prediction process, which allows access to old time technology. Current sub-micron technology indicates that the failure rate is as low as 1.5 fits.
