Web(ethylmethylaminohafnium) [TEMAHf] has primarily been used in the ALD process due to its relatively high vapor pressure, thermal stability on Si-wafer, and weak metal-nitrogen bonding; TEMAHf can be used to fabricate metal-oxide films with a higher purity level [6]. Accordingly, precursor choice is important. Another factor as important WebDec 31, 2024 · TEMAHf is a low vapour pressure precursor and needs to be heated to realize sufficient vapour pressure. However, this temperature should not exceed its thermal breakdown temperature of 140 °C [27]. In the present study, boosting mechanism is adopted for.

WebApr 9, 2024 · All TEMAHf pulses were separated by 0.9 s long purge periods. The exposure to the sequence of TEMAHf pulses was, again, followed by 0.1 s long H 2 O pulses repeated 120 times, whereby the pulses were separated by 0.9 s long purge periods. The buffer layer was, thus, formed similarly to the cycling sequence exploited in our earlier study .
