We describe an advanced 0.13pm CMOS technology platform optimized for density, performance, low power and analoghixed signal applications. Up to 8 levels of Copper interconnect with industries first true low-k dielectric (SiLK, k=2.7) [ l ] result in superior interconnect performance at aggressive pitches. A 2.28pm2 SRAM cell is manufactured with high yield by introducing elongated local interconnects on the contact level without increasing process complexity. Trench based embedded DRAM is offered for large area memory. Modular analog devices as well as passive components like resistors, MIM capacitors and intrinsic inductors are integrated.

Low voltage operation in s u b -0 . 2 5~ requires the simultaneous integration of all components on a single chiphigh performance, low leakage and mixed-signal componentsis crucial. In this paper we present the successful integration of a low leakage gate-dielectric using a triple-gateoxide process with 16&24&52A, a low-k BEOL and mixed signal components. The 1.5V S U M cell

Based on a generic digital process (1) additional modules can be added in a modularand cost effective-manner for mixed signal as well as for eDRAM applications offering a maximum of flexibility for product designers. For mixed signal applications a precision metal-insulator-metal capacitor (MIMCAP) was developed. This is for the first time a realization of a metal-insulatormetal capacitor in a copper dual damascene metallization scheme.
