Special field:
High-Voltage CMOS and Bipolar-CMOS-DMOS
for industrial and automotive products

One focus of QPX services is on robustness of technologies containing lateral & vertical DMOS and/or high-voltage MOS/bipolar transistors with high DC/transient voltage requirements. The IC products fabricated in these technologies often have to operate in harsh environments (e.g. automotives) being exposed to a variety of EM disturbances and large temperature ranges.

A frequent cause of customer returns of
malfunctioning ICs is missing signal integrity or EOS failures caused by ESD protection devices. To avoid these kind of failures the holding voltage of ESD protection device can be increased above the supply voltage.
