Abstract :
A leading edge 130 nm generation logic technology with 6 layers of dual damascene Cu interconnects is reported. Dual Vt transistors are employed with 1.5 nm thick gate oxide and operating at 1.3 V. High Vt transistors have drive currents of 1.03 mA//spl mu/m and 0.5 mA//spl mu/m for NMOS and PMOS respectively, while low Vt transistors have currents of 1.17 mA//spl mu/m and 0.6 mA//spl mu/m respectively. Technology design rules allow a 6-T SRAM cell with an area of 2.45 /spl mu/m/sup 2/, while array specific design rule give the densest SRAM reported to date, the 6-T cell has an area of only 2.09 /spl mu/m/sup 2/. Excellent yield and performance is demonstrated on a 18 Mbit CMOS SRAM.
