United Microelectronics Corporation, a global semiconductor foundry, has unveiled its 28eHV+ platform, the latest enhancement to its 28nm integrated high voltage (eHV) technology. Delivering higher power-efficient visual quality, 28eHV+ is an ideal display driver solution for powering next-generation displays used in smartphones, virtual and augmented reality devices, and IoT.
Compared to the proven 28nm eHV process, UMC’s 28eHV+ solution offers up to 15% reduction in power consumption without compromising image quality or data rates, meeting the demand for longer life the battery of the devices. It also offers optimized features to allow higher precision in voltage control and greater flexibility for chip designers.
For eHV technology, 28nm is currently the most advanced casting process for Small Panel Display Driver ICs (SDDI), which is used in AMOLED panels that are increasingly being adopted in high-end smartphones and AR/VR devices. . UMC is the vendor with more than 85% of the 28nm SDDI market and has shipped more than 400 million units since volume production began in 2020.
“We are excited to introduce our 28eHV+ platform, which has already gained interest from several customers and will go into production in the first half of 2023,” says Steven Hsu, vice president of technology development at UMC. “As a provider of specialized foundry technologies, UMC offers differentiated solutions that are aligned with our customers’ roadmaps, enabling them to capture opportunities in fast-growing markets. Following the release of 28eHV+, our development teams will work to extend our display driver solutions to 22nm and beyond.”
UMC’s 28eHV+ technology features the industry’s smallest SRAM bit cells, reducing chip area. It is based on the company’s next-generation 28nm High-K/Metal Gate technology, which features superior leakage and dynamic power performance.
