摘要

This paper gives an overview of the device physics and the process integration challenges of fully-depleted (FD) silicon-on-insulator (SOI) devices for advanced technology nodes. In the first part of the presentation, the physics related to the operation of ultra-thin film devices is described as well as how device scaling is impacted by the device parameters. Next, major fabrication challenges faced by fully-depleted SOI devices are reviewed along with their most recent progress. The technology modules reviewed include isolation, substrate engineering (limits of ultra-thin layers, strained layers, buried insulator materials,...), gate stack (high k and gate workfunction engineering techniques), methods for reducing SD parasitic resistance, such as elevated source/drain, as well as stress techniques.
