Abstract :
Advanced process integration with low-k fluorine-doped interlayer dielectric was presented. Performance improvement due to wiring capacitance reduction was confirmed from speed analysis of inverter delay time by 7%. And it was clarified that there was no influence of fluorine in interlayer dielectric to MOSFET´s reliability. This process was carefully optimized from total CMOS integration point of view and was applied to development and production of advanced logic LSI.
