UMC Launches Advanced 55nm BCD Platform to Power Next-Generation Automotive, Industrial, and Consumer Applications

Hsinchu, Taiwan – October 22, 2025 – United Microelectronics Corporation (NYSE: UMC, TWSE: 2303) today announced the launch of its new 55 nm Bipolar-CMOS-DMOS (BCD) platform, designed to significantly elevate power efficiency and integration in next-generation smartphones, consumer electronics, automotive, and industrial applications.

Advancing Power Management with Higher Integration

As device functions proliferate and power-management demands intensify, UMC’s 55 nm BCD platform enables a higher level of mixed-signal and power integration—bringing analog, digital, and power functions together on a single chip.

Key features of the platform include:

• A Non-Epitaxy (Non-EPI) process optimized for mobile and consumer devices.
• An Epitaxy (EPI) process compliant with AEC-Q100 Grade 0 automotive standards and supporting operating voltages up to 150 V.
• A Silicon-on-Insulator (SOI) process variant tailored for high-grade automotive and industrial applications, compliant with AEC-Q100 Grade 1, offering superior noise-reduction and low-leakage characteristics.
• Integration of ultra-thick metal (UTM), embedded flash, and resistive random-access memory (RRAM) technologies, enabling smaller chip area, reduced power consumption, and improved flexibility in power-circuit design.

Reinforcing UMC’s BCD Portfolio and Market Position

“With the readiness of our 55 nm BCD platform, we mark a major milestone for UMC—rounding out our specialty BCD technology portfolio and boosting our competitiveness in the power-management market,” said Steven Hsu, Vice President of Technology Development at UMC.

UMC’s BCD portfolio now spans nodes from 0.35 µm, 0.25 µm, 0.18 µm, 0.11 µm down to 55 nm, offering customers robust voltage capabilities, broad IP resources, and strong design support.

Applications and Market Impact

The new 55 nm BCD platform is well-suited for:

• Power ICs in smartphones, wearables, and mobile/consumer electronics
• Automotive electronic subsystems requiring high reliability and stringent standards
• Smart home, smart factory, and industrial power management applications

By offering multiple process variants tailored to different market segments, UMC enables customers to choose the optimum balance of cost, performance, voltage capability, and integration.
