WebDec 31, 2024 · A number of precursors are available for ALD film growth, which have varied range of vapour pressure and therefore a suitable mechanism for their effective delivery to the reaction chamber is important to have saturated ALD thin film growth. TEMAHf is a low vapour pressure precursor and needs to be heated to realize sufficient vapour pressure. Webwet process [11]. TEMAHf and TEMASi were used as the Hf and Si precursors and ozone was used as an oxidizing agent. Alternating pulses of precursor vapors and ozone were introduced at substrate temperatures below 400ºC to provide HfO2 (TEMAHf based) or homogeneous HfxSi1-xO (TEMAHf + TEMASi based) films.
