Paper Abstract

One of the challenges of scaling Shallow Trench Isolation (STI) is controlling the Vt and Idsat of narrow devices. In this paper, we show that Idsat of narrow devices is strongly affected by changes in mobility due to stress from the trench edge. We also show that Vt and leakage of narrow devices is controlled by dopant re-distribution in the channel caused by TED and boron segregation to the trench sidewalls.
