Growth of single-phase nanostructured Er$$_2$$O$$_3$$ thin films on Si (100) by ion beam sputter deposition

Mao, W.*; Fujita, Masaya*; Chikada, Takumi*; Yamaguchi, Kenji; Suzuki, Akihiro*; Terai, Takayuki*; Matsuzaki, Hiroyuki*

Single-phase nanocrystalline thin films of Er$$_2$$O$$_3$$ (440) has been first prepared using Si (100) substrates by ion beam sputter deposition at 973 K at a pressure of $$<$$ 10$$^{-5}$$ Pa and $${it in}$$-$${it situ}$$ annealing at 1023 K at a pressure of $$approx$$ 10$$^{-7}$$ Pa. Er silicides formed during the deposition are eliminated via the annealing, which results in the single phase and the smooth surface of the Er$$_2$$O$$_3$$ thin films. The epitaxial relationship between Si (100) and Er$$_2$$O$$_3$$ (110) is clarified by X-ray diffraction and reflection high energy electron diffraction.

Film growth method by means of ion beam sputtering

Yamaguchi, Kenji

Shirisaidokei Handotai No Kagaku To Gijutsu, p.113 - 121, 2014/09

This article describes first the basic aspects of sputtering phenomena based on ion beam - solid interactions, followed by introduction of ion beam sputter deposition (IBSD) method for thin film fabrication. The article further introduces the experimental apparatus for IBSD application, equipped with an ion beam irradiation system for sputter-etching of the substrate surface. It is shown that this method is suitable for fabrication of semiconducting iron silicide film on Si substrate. The experimental results revealed that the obtained thin film is highly-oriented and continuous, forming atomically flat interface between film and the substrate.

On the formation of $$beta$$-FeSi$$_{2}$$ using Ion Beam Sputter Deposition (IBSD) method, sputter etching (SE) followed by thermal annealing is effective substrate treatment to obtain highly (100) oriented $$beta$$-FeSi$$_{2}$$ on Si (100). However the best condition of these treatments are not yet known. In this work, the effect of sputter etching (SE) together with annealing process on the orientation of the film is investigated. In prior to the deposition of Fe, the substrate is irradiated by Ne$$^{+}$$ ion with various energy and fluence followed by thermal annealing at 1027 K for 60 minuets. The overall results show the most suitable SE condition using Ne$$^{+}$$ ion on IBSD method is the energy of 1keV with the fluence of 30$$times$$10$$^{19}$$ ions/m$$^{2}$$.

Fabrication of high-quality Er$$_2$$O$$_3$$ thin film using ion beam sputter deposition method

Fujita, Masaya*; Asaoka, Hidehito; Yamaguchi, Kenji

no journal, , 

Ion beam sputter deposition method has been successfully employed to obtain highly-oriented Er$$_2$$O$$_3$$ thin film on Si substrate. In this study, thermal annealing of the "as deposited" film was performed under the same atmosphere as in the sputter deposition process. The XRD analysis revealed that the obtained film was found to grow in other orientations, which are not in the epitaxial relationship with Si(100) substrate. These findings were compared with previously obtained results to discuss the possible film growth mechanism.
