UMC Unveils Novel 80nm SDDI Foundry Process For SRAM Bitcell

News

United Microelectronics Corporation (UMC), has introduced an 80nm SDDI (Small-panel Display Driver IC) foundry process with one of the most competitive SDDI SRAM bitcells in the foundry industry.

The low power, advanced SRAM solution applies aggressive foundry design aims to shrink the bitcell size down to 0.714 um2 to enable HD720/WXGA smartphone resolutions, far less than the typical 0.81um2 size used in current 80nm SDDI processes.

UMC says its process is ready for mass production, with several Tier 1 customers engaged for HD720/WXGA smartphone resolution applications.

Yau Kae Sheu, senior director of UMC's 12-inch Specialty Technology Development division, says, "With the proliferation of today's smartphones, UMC has stayed at the forefront of specialty technology development to help the industry consistently introduce newer, feature-enhanced products. Our available 80nm and upcoming 55nm SDDI process will help new and existing display driver customers realise higher resolution with lower power consumption for upcoming generations of smartphone displays."

UMC has shipped over 300 million SDDI chips at 0.13µm for today's mainstream smartphone using WVGA and qHD resolutions.

In addition to the 0.13µm and 80nm SDDI processes, the foundry is also targeting next generation smartphone displays featuring full-HD with the industry's first 55nm SDDI process, which will be ready for customer design-in this quarter.
