摘要
This paper discusses the BEOL development, qualification, and manufacturing ramp of IBM's 90nm generation RF-CMOS technology. This technology, which was qualified in both 200mm and 300mm fabs, was developed using IBM's base 90nm generation and includes all standard RF analog features and RF circuit models [3]. BEOL RF analog features include analog wiring, which consists of 3um Cu and/or 4um AlCu wires, 2fF/mu m(2) Si3N4 (nitride) and 5.61F/mu m(2) High-K metal-insulator-metal (MIM) capacitors, 0.3-1.6fF/mu m(2) vertical-natural capacitors formed with native Cu wires and vias, FEOL polysilicon and crystalline silicon resistors, and precision 8% tolerance BEOL TaN resistors. As compared to IBM's 130nm generation RF-CMOS, the key changes include three BEOL capacitor options, dual damascene and tapered via analog wiring, and low-K SiCOH intermetal dielectric (IMD).
