Energy Efficiency of Products

As part of its sustainability strategy, UMC aims to increase investment in technologies that deliver enhanced energy efficiency, reducing carbon emissions along the value chain as well as the carbon footprints of end-products. UMC's technologies also contribute to global climate change mitigation by providing semiconductors to power electric vehicles, smart energy management systems, industrial automation, and optimization technology and systems. To align its technology development roadmap with carbon reduction goals, the company has set incremental goals through 2030 to expand the proportion of overall revenue derived from sustainable products.


Green Technology Development

UMC offers ultra-low power (ULP) and ultra-low leakage (ULL) logic technology platforms, which can be integrated with the company's leading specialty processes to enhance energy saving characteristics of end-products.


Logic Process Technology

For its 28nm logic process, UMC provides two types of high-performance and ultra-low-power options to suit different customer needs, including automotive applications. The 22nm logic process platform provides lower core operating voltage, demonstrating ultra-low leakage and energy-saving features. The 14nm process is more suitable for computing and data processing due to its high performance, low power consumption and low latency.


Embedded Non-Volatile Memory Technology (eNVM)

UMC offers state-of-the-art eNVM solutions to meet a variety of embedded system applications. In addition to the standard eNVM solutions, UMC has also successfully developed resistive memory (RRAM) and magnetoresistive memory (MRAM) technologies, which can be embedded in logic processes and operate with very low standby electrical current, reducing the power consumption of products in end applications. Coupled with robust logic processes for peripheral devices, UMC produces energy efficient microcontrollers for a range of applications including automotive, smart factory, and consumer products.


Embedded High Voltage Technology (eHV)

UMC has the industry's broadest portfolio of eHV process technologies and corresponding intellectual property solutions for display panel driver chips of all sizes. UMC's ultra-low leakage solution enables customers to integrate control logic, gate drivers, source drivers, and memories on the same IC to form a system-on-chip (SoC), which can achieve multiplexing and improve product performance without increasing power consumption.


Bipolar-CMOS-DMOS Technology (BCD)

UMC's BCD platforms, backed by comprehensive eNVM options, deliver complete power management functions in a single chip. Customers' power management ICs produced using BCD technology exhibit lower energy loss during voltage conversion and boast a smaller form factor, making it a preferred solution for developing end-products that is more energy efficient.


Radio-Frequency Silicon-on-Insulator Technology (RFSOI)

UMC's RFSOI technology, with its unique substrate characteristics capable of preventing low and high frequency doubled harmonics and reducing power loss, exhibits outstanding energy efficiency in end applications.

Micro-controller unit (MCU)

The MCU circuits have energy efficient characteristics to control the components operation while saving electrical power in the same time. In general, MCU circuits have time pulses, feedback systems, only operate at the right time, and save power with a very low Standby current in other idle times. Such that MCUs are always able to minimize power consumption and achieve higher energy efficiency. UMC’s MCUs are widely popular in end applications, and in fact, they can indeed demonstrate the effect of energy saving and power conserving, which contribute to the progress towards a low-carbon economy and therefore are recognized as sustainable products.


Power management IC (PMIC)

Power management IC (PMIC) can improve the power efficiency of electronic devices, reduce energy loss during voltage conversion, and thereby achieve energy saving. UMC's Bipolar-CMOS-DMOS (BCD) technology platforms, backed by comprehensive eNVM options, deliver complete power management functions in a single chip. Customers' power management ICs produced using BCD technology exhibit lower energy loss during voltage conversion and boast a smaller form factor, making it a preferred solution for developing end-products that is more energy efficient.


Display driver IC (DDI)

Based on superior high-voltage process and ultra-low leakage logic/mixed-signal (MS) process technology, UMC has a full range of high-voltage process technology platforms from 0.8μm to 22nm to provide complete solutions for small to large display driver ICs designs. The development of 28nm ultra-low power embedded high-voltage platform 28eHV-LP process technology, featuring the industry's smallest SRAM bit cell, thereby reducing the chip area, was completed. Compared to the proven 28nm eHV process, UMC’s 28eHV-LP solution offers up to 15% reduction in power consumption without compromising image quality or data rate, addressing the demand for longer battery life of devices. The 28eHV-LP SDDI, used in AMOLED panels, have been widely adopted in high-end smartphones and AR/VR devices increasingly.


Automotive Electronics

The large-scale electrification of vehicles is also taking place rapidly as consumers become more environmentally conscious and as governments roll out policies in line with their net zero carbon emissions goals. UMC Auto is a comprehensive platform, that the automotive electronic products are strictly qualified and the fabs comply with the rigorous verification standards. Moreover, UMC's automotive electronic products also have energy-efficient features of low power consumption and low leakage, which can grasp the business opportunities of low-carbon economy development in expanding the clean technology end applications of hybrid/electric vehicles, and further help promote UMC's overall value chain with customers towards the goal of net zero carbon emissions.
