摘要

提出了一种具有成本效益的附加工艺模块,用于降低基于逻辑CMOS工艺的RF/BiCMOS和RF/CMOS技术中RF电感器和互连的欧姆损耗。该模块是基于薄CMOS互连层顶部金属层的局部增厚镀铜。在传统的5-/spl ω /-cm硅衬底上实现了10-nH电感的创纪录质量因子13。

Saddle add-on metallisation (SAM) for RF inductor implementation in standard IC interconnects
A cost-effective add-on process module is proposed for reduction of ohmic losses of RF inductors and interconnects in RF/BiCMOS and RF/CMOS technologies built on logic CMOS processes. The module is based on the local thickening of the top metal layer of the thin CMOS interconnects by Cu plating. A record quality factor of 13 is achieved for a 10-nH inductor on a conventional 5-/spl Omega/-cm silicon substrate.
