WebEtching the MoS2 surface resulted in a threshold voltage shift of 0.2 V per nanometer of MoS2 removed (for MoS2 thicknesses >15nm). For etched MoS2 layers reduced to < 15 nm, a threshold voltage change of ~1.8 V per nanometer was measured. WebThe pH effects on Co, Cu and W etching are reported. Diluted acids, such as 1% HF and 1% HCl, demonstrate etch rate profiles suitable for selective Co vs. W etch applications. Ru etch chemistries are alkaline oxidative based and expanded to meet 3 nm and below integration needs.

WebAt temperatures between 320 and 400 °C oxidative thermal etching regime has been observed in the case of single MoS 2 flakes [ 33, 34, 35, 40 ]. Above 400–410 °C substantial oxidation involving decrease of the flakes’ volume has been observed in air [ 41, 45 ]. WebChemically etching molybdenum is ideal for use in many industry sectors including the medical, aerospace, defence, marine and telecommunications industries, due to it’s ductility and high corrosion resistant properties, and has one of the highest melting points of all the pure elements.
