WebIn this paper, we report the plasma-enhanced atomic layer deposition (PEALD) of TiO2 and TiO2/Al2O3 nanolaminate films on p-Si(100) to fabricate metal-oxide-semiconductor (MOS) capacitors. In the PEALD process, we used titanium tetraisopropoxide ... The base pressure of the reactor was below 10−2 mbar, and, during the deposition, the gas ... WebThe bond strength of ALD Al2O3 films was not changed obviously by raising the deposition power, but it experienced a slight decrease after H2 plasma post-treatment. The water in the debonding atmosphere influenced the bond strength of standard ALD Al2O3 films greatly, which was 0.54 J m−2 in humid air and 1.00 J m−2 in anhydrous N2.

WebApr 5, 2024 · ALD Al 2 O 3 is widely reported and easy to be reproduced. As long as Al 2 O 3 is reproduced on an ALD plant, the exposure time of a new precursor could be estimated according to equation (4). Much less trial experiments are then needed to determine the best exposure pulse length. WebThe surface chemistry reaction for ALD-Al 2 O 3 can be expressed as The overall reaction is refers to the functional groups adsorbed on the deposition surface, showing that self-stop gas-solid reaction is the basis of ALD. TMA/H 2 O ALD process can be divided into 4 and 4 two half reactions, and the precursor molecule performs the chemical adsorption firstly …
