Abstract for Presentation

Atomic-layer-deposited atomically thin In2O3 channel for BEOL logic and memory applications



In this talk, we report on the first demonstration of atomically thin In2O3 channel for logic and memory devices by a back-end-of-line (BEOL) compatible atomic layer deposition (ALD) process [1,2]. High performance planar In2O3 transistors with high mobility of 113 cm2/V⋅s and record high maximum drain current of 10 mA/um in a planar device and 20 mA/um in a single-channel gate-all-around (GAA) nanoribbon device are achieved by channel thickness engineering and post-deposition annealing [3]. This is the first time to realize a single channel field-effect transistor with two digits drain current in any kind of semiconductors. ALD In2O3 3D Fin transistors are also demonstrated, benefiting from the conformal deposition capability of ALD [4]. High-performance In2O3 ferro-electric transistors are demonstrated using ALD HfZrO2 gating with >2.2V large memory window, >10 years retention and >109 endurance [4,5]. These results suggest ALD oxide semiconductors and devices have unique advantages and are promising toward BEOL-compatible monolithic 3D integration [7].
