GISTEL, Belgium--(BUSINESS WIRE)--Sofics® bvba (www.sofics.com) of Gistel has been selected by ZMDI (www.zmdi.com) of Dresden, Germany to develop a library of PowerQubic® on-chip electrostatic discharge and electrical overstress (ESD/EOS) clamps for devices fabricated in a TSMC 0.18um gen II BCD (bipolar-CMOS-DMOS) process with 24V interfaces.
“Automotive electronics are exposed to high levels of electrical stress, so ZMDI needs the best available ESD/EOS protection for our products”
After conducting two evaluations of Sofics PowerQubic® technology prior to this agreement, to test the technology’s potential for enhancing device reliability while holding down manufacturing costs, ZMDI decided to work closely with Sofics on PowerQubic ESD/EOS protection for their latest devices.
Sofics is a leading provider of ESD solutions for integrated circuits. ZMDI is a major supplier of application-specific ICs for automotive and industrial electronics, medical technology, and infrared interfaces, including heavy-duty mixed analog and digital ICs.
Under the licensing agreement Sofics will adapt PowerQubic technology to ZMDI’s requirements, which include meeting IEC electromagnetic compatibility (EMC) standards for ESD immunity in automotive electronics.
“Automotive electronics are exposed to high levels of electrical stress, so ZMDI needs the best available ESD/EOS protection for our products,” said Frank Shulze, Business Line Manager, Sensing and Automotive. “We ran evaluations of several ESD solutions for chips fabricated in a 0.25um BCD process. PowerQubic clamps were superior in the EMC test, as well as in parameters such as meeting flexible clamping voltage specifications.
“So we selected Sofics to provide ESD/EOS protection for a new line of 0.18um devices that will meet our specifications, at a lower cost than building the clamps from scratch.”
According to Koen Verhaege, Sofics CEO, PowerQubic is a proven technology already implemented in several processes that offers economic advantages too.
“Because PowerQubic does not require process changes, licensees can actually lower their overall cost by opting for our advanced technology.
“We are very pleased that ZMDI has chosen our technology for their new 24V-compatible devices.”
PowerQubic incorporates proprietary clamps that dissipate more energy per area than any other device, allowing it to deliver the highest level of ESD/EOS protection available for high-voltage ICs. PowerQubic (PQ) and TakeCharge® (TC) ESD/EOS technologies from Sofics are proven across multiple applications, processes, and foundries. TSMC-9000 quality approval for both PQ and TC has been granted or is pending in several processes.
