Electrical performance of dense and isolated n-type FinFETs in micro-loading effect

Abstract

The micro-loading effect in this work seems obviously. According to the extraction of drive current (IDS) for dense and isolated FinFET devices at the on-drawn layout (W/L=0.11/0.5 (μm/μm), the ratio with 11-fin fingers vs. single fin was 10.01. Using the re-work concept to derive the un-etching depth (ΔH) located at the inner sidewall fin height was still around 2.4 nm as the outer sidewall height (Hfin) was 90 nm.
