Abstract

IGZO transistors with various gate/drain-offset lengths (Lgdo) were fabricated with the film-profile-engineering method. Breakdown voltage (VBD) of the fabricated devices increases while transconductance (gm) decreases with increasing Lgdo. In contrast, threshold voltage and subthreshold swing remain relatively unchanged. Vbd of ∼80 V is obtained with Lgdo of 0.3 μm. Output characteristics with operation voltage up to 50 V are also demonstrated, evidencing the capability of the device for high-voltage operation. Impact of hot-carrier stress is also investigated in this work.
