Philips and IMEC successfully conclude exploration and optimization of devices for the 65nm CMOS technology node

16/09/2003

Leuven, Belgium, September 16, 2003 --- The completion of fabrication of 65nm CMOS devices with good electrical performance marks the second milestone within the strategic partnership between Philips and the micro- and nanoelectronics research center IMEC.

Philips Research and IMEC formed a strategic alliance beginning of 2000 to explore the key processing and integration steps in advanced CMOS technologies. Work on the 65nm CMOS technology node began in early 2002 after a successful first step had been made in the joint exploration of the 90nm CMOS technology node.

The 65nm technology is based on a scaled version of planar 90nm bulk CMOS. Devices feature 45nm gate length, equivalent oxide thickness of 14Å, 100nm thick polysilicon gates and sub-20nm junction depths. Gate dielectric recipes were optimized through plasma nitridation of ultra-thin oxides for reduction of gate leakage and suppression of boron penetration. Shallow source/drain engineering was performed using ultra-low energy implantation in combination with germanium pre-amorphization and fluorine co-implantation (PMOST) and fast ramping high-temperature spike anneals. Low-temperature deposition techniques were introduced in the back-end for spacer, salicide blocking and PMD (pre-metal dielectric) layers to avoid excessive dopant diffusion and de-activation. Finally an advanced two-step nickel salicidation was successfully integrated leading to improved control of line width effects as well as reduced junction leakage and contact resistance.

Drive currents of 790µA/µm for NMOST and 355µA/µm for PMOST were obtained at Vdd=1V and an off-state current of 100nA/µm. Devices exhibit good short channel effects control. “The achieved electrical performance, which compares favorably with results from other companies, demonstrates that a successful step has been made in the joint exploration of the 65nm technology at IMEC and Philips Research,” says Dr. Carel van der Poel, Senior Vice President of Philips Research.

“These results again prove the success of our strategic alliance with Philips, through which we have created a larger pool of brainpower at IMEC and merged our complementary competences,” notes Dr. Luc Van den hove, Vice President Silicon Process and Device Technology at IMEC. “In this way, both IMEC and Philips have strengthened their position in state-of-the-art silicon technologies.”
