Abstract
Carbon is proposed as a new FEOL material with high conductivity and thermal stability for CMOS integration. Here the application of carbon-based electrodes for future DRAM cell capacitors is presented. Trench capacitors with high-k dielectrics have been realized, fulfilling the requirements for serial resistance, capacitance, leakage, reliability and temperature stability beyond the 40 nm technology node.
