Improving the Quality of PVD Cu Seed Layer

Authors from Novellus Systems and The University of Illinois describe how the quality of PVD deposited barrier/seed interface in copper interconnect metallization was significantly improved by enhancing Cu nucleation on the Ta surface.

Considerations for Porting a Bulk CMOS Design to FD-SOI

Technologists describe a straight port of an existing bulk CMOS design to
FD-SOI at the same node, obtaining the value of fully depleted SOI for a
modest redesign effort.

RF Substrate Technologies for Mobile Communications

Two Soitec Group managers — Eric Desbonnets and Stéphane Laurent — describe how SOI wafers support RF technology development.

Manufacturing Closure with Calibre InRoute and Olympus-SoC

This Mentor Graphics paper describes the physical signoff challenges seen in advanced node designs.

Frequently Asked Questions About FD-SOI

Xavier Cauchy of Soitec and François Andrieu at LETI raise some of the technical issues surrounding fully depleted SOI technology. The authors compare FD-SOI to FinFETs, describe how non-digital transistors can be handled, and provide a list of references for further reading.

Design Impacts of Fully Depleted SOI

Xavier Cauchy, digital applications manager at Soitec, describes the design implications of fully depleted SOI technology at the 22/20 nm node.
