AC transconductance: A novel method to characterize oxide traps in advanced FETs without a body contact

A novel ac transconductance method for oxide trap characterization is introduced, validated and demonstrated on two advanced FETs without a body contact, including Si Ultra-Thin-Body and BOX (UTBB) Fully Depleted (FD) SOI MOSFETs and InGaAs MOSFETs. The proposed method can extract the energy and spatial distributions of oxide traps in a variety of device structures, gate areas, and channel materials.
