ExperimentalMolybdenum nitride films were deposited by R.F. (13.56 MHz) reactive magnetron sputtering in an NORDIKO 3500 system as described in a previous paper. The target is a 100 mm diameter disk of pure molybdenum (purity 99.98 at.%). The chamber is pumped down via a cryogenic pump backed by a primary pump, allowing a residual vacuum of about 10−7 mbar. Argon (working gas) and nitrogen (reactive gas) were introduced into the chamber through a mass flow controller, while the absolute working pressure was fixed at 5× 10−3 mbar. The gas pressure was measured using a BOC EDWARDS gauge. The nitrogen partial pressures reach values of 20%, 30%, 40% and 50% of the absolute working pressure. The target to substrate distance was about 170 mm with an angle of 30°, with respect to the substrate normal. The R.F. power density on the cathode was fixed at 3.18 W·cm−2, with the R.F. voltage on the target fixed at 800 V. All depositions were performed at room temperature.
實驗。<br>如前一篇論文所述,R.F.(13.56 MHz)反應磁龍在NORDIKO 3500系統中濺射沉積了氮化物薄膜。目標是一個直徑為 100 mm 的純摩爾(純度為 99.98 在.%)腔室通過由主泵支援的低溫泵泵下,允許殘餘真空約 10~7 mbar。通過品質流量控制器將 Argon(工作氣體)和氮氣(反應氣體)引入腔室,而絕對工作壓力固定在 5× 10×3 mbar。使用 BOC EDWARDS 儀錶測量氣壓。氮氣部分壓力達到絕對工作壓力的20%、30%、40%和50%以上。與基板法線一樣,基板距離目標約為170 mm,角度為30°。陰極上的 R.F. 功率密度固定在 3.18 W+cm+2,目標上的 R.F. 電壓固定在 800 V。所有沉積都是在室溫下進行的。
