DC reactive magnetron sputtering was used to deposit few-nanometer-thick films of niobium nitride for fabrication of superconducting devices. Over 1000 samples were deposited on a variety of substrates under various chamber conditions. Sheet resistance thickness and.
When a highly insulating compound is deposited using DC reactive magnetron sputtering both the metallic and the insulating states exist simultaneously on the cathode surface due to the differential poisoning of magnetron cathodes. Since sputtering is a momentum transfer process ion-bombardment of the cathode causes sputtering of both the insulating layers Ins and the. CuAlO films were deposited via dc reactive magnetron sputtering in a load-locked vacuum system described elsewhere15 A metallic 5050 at.
CuAl target of 9999 purity was used for all of the depositions. The target to sub-strate distance was 14 cm. The target was kept at a con-stant power of 100 W throughout the depositions.
A reactive magnetron sputtering system was modified such that an end-Hall ion source was installed to assist the growing thin film from reactive magnetron sputtering and the TSD was increased to 350 mm. The optical and structural properties of titanium oxide thin films prepared by the ion-beam-assisted DC reactive magnetron sputtering were investigated and compared with those of. In the present work Vanadium oxide thin films were prepared by DC reactive magnetron sputtering at different oxygen partial pressure and thermally annealed in Ar atmosphere at 500C for 2 hours.
The microstructure transmittance optical band gap resistivity and temperature coefficient resistance TCR were measured. Conventional direct current dc magnetron sputtering of nonconducting oxide films via reactive sputtering is extremely difficult. Without good separation of the oxygen from the target the surface of the target rapidly becomes covered with an oxide film or poisoned when there is a high enough partial pressure of the reactive gas to form the desired film composition on the substrate.
Reactive DC Magnetron Sputtering Since DC power delivery is simpler and generally less expensive than an equivalent RF unit there is an incentive for adoption in industrial applications. This is an instance where the thin film industry has been served well by the development of electrical components and fast control of power supplies. Among these deposition methods DC reactive magnetron sputter deposition technique has received considerable attention because of the advantage in the preparation of metal oxide films by sputtering the metallic target in the present of reactive gas of oxygen at low deposition temperatures and on to large area substrates.
Physical properties of sputtered ZrO 2 films depend mainly on sputter. Plasma-Enhanced Reactive Magnetron Sputtering Assisted with Inductively Coupled Plasma for Reactivity-Controlled Deposition of Microcrystalline Silicon Thin Films Kosuke Takenaka 1 Yuichi Setsuhara and Akinori Ebe2 1Joining and Welding Research Institute Osaka University Ibaraki Osaka 567-0047 Japan 2EMD Corporation Yasu Shiga 520-2323 Japan E-mail. Experimental Part A homemade dc reactive magnetron plasma sputtering system was designed and constructed for thin film deposition purposes.
What is Sputtering. Sputtering is a vacuum deposition technique used to deposit thin-film of a material onto a surface. The substrates are placed into the vacuum chamber and pumped down to process pressure.
First creating gaseous plasma accelerates the ions from this plasma into some source material. It is used to knock atoms out of the target. The molecules atoms ions and electrons on the.
One of the more useful accessories to have on a sputter system meant for reactive sputtering is a Residual Gas Analyzer RGA or Process Gas Analyzer PGA in order to monitor the actual partial pressures of gas species involved in the process. These can then be controlled by means of gas Mass Flow Controllers MFCs along with a pumping throttle valve and suitable control. The MoN films were prepared by DC reactive magnetron sputtering using the AJA International ATC Orion Sputtering System.
The films were deposited from the 2 inch pure Mo target 9995 in an argon Ar and nitrogen N 2 atmosphere on substrates which were placed without any thermal glue on a heater. The CuAlO 2 films were deposited on glass substrates by dc reactive magnetron sputtering using the copperaluminum alloy in the ratio 13 due to the difference in the sputter yield target. The sputtering system is capable of producing the base pressure of 5 10 6 mbar.
The sputter chamber was pumped with diffusion pump and rotary pump combination. The pressure in the sputter chamber was. CrAlN films were synthesized by DC reactive magnetron sputtering.
The influence of the aluminium content on the microstructure hardness and the friction coefficient of the CrAlN films have been investigated. Results indicate that all CrAlN coatings present a columnar and dense structure. Also CrAlN coatings present a better hardness than CrN coating.
The increase of Al rate from 35 to 11 is. Magnetron sputtering increases the plasma density by introducing a magnetic field on the surface of the target cathode and utilizing the constraints of the magnetic field on the charged particles to increase the sputtering rate. Magnetron sputtering includes many types such as direct current DC magnetron sputtering and radio frequency RF magnetron sputtering each has a different working.
