Reducing BEOL Parasitic Capacitance using Air Gaps

By: Michael Hargrove, SP&I Engineer

Reducing back-end-of-line (BEOL) interconnect parasitic capacitance remains a focus for advanced technology node development. Porous low-k dielectric materials have been used to achieve reduced capacitance, however, these materials remain fragile and prone to reliability concerns. More recently, air gap has been successfully incorporated into 14nm technology [1], and numerous schemes have been proposed to create the air gap [2-3].  There are many challenges to integrate air gap in BEOL such as process margin for un-landed vias and overall increased process complexity. In this paper, we introduce virtual fabrication (SEMulator3D®) as a means to study air gap process integration optimization and resulting interconnect capacitance reduction. Initial calibration to published air gap data is demonstrated. read more…

Using Advanced Statistical Analysis to improve FinFET transistor performance

By: Jimmy Gu, SP&I Staff Engineer

Trial and error wafer fabrication is commonly used to study the effect of process changes in the development of FinFET and other advanced semiconductor technologies.  Due to the interaction of upstream unit process parameters (such as deposition conformality, etch anisotropy, selectivity) during actual fabrication, variations based upon process changes can be highly complex. Process simulators that mimic fab unit processes can now be used to model these complex interactions.  They can also help process engineers identify important process and/or design parameters that drive certain critical targets such as CDs, yield limiting spacing, 3D design rule violations, resistance/capacitance, and other process and design issues.   The number of possible parameters that affect device performance and yield can be quite large, so statistical analysis can provide useful insight and help identify critical performance parameters.  Coventor’s SEMulator3D virtual fabrication (or process simulation) platform contains an analytics module for conducting virtual design-of-experiments and statistical analysis. I would like to use an example of a 14nm FinFET process flow in SEMulator3D to identify important process parameters that drive fin top CD, which is a key metric for transistor performance.

Why Fabs Worry About Tool Parts

By Mark Lapedus

Achieving high yields with acceptable costs is becoming much more difficult as chipmakers migrate to next-generation 3D NAND and finFET devices—but not just because of rising complexity or lithography issues.

To fabricate an advanced logic chip, for example, a wafer moves from one piece of equipment to another in what amounts to 1,000 process steps or more in a fab. Any glitch with the equipment or a process step can cause defects, thereby impacting yield. The culprit may be a malfunction in seemingly insignificant parts or sub-systems in the equipment itself.
