In other words, in the second annealing process, the initial temperature of {TAIL ~ the second reactor chamber} can be substantially room temperature, subsequently ramped up to a predetermined process temperature, i.e. the peak temperature of {HEAD ~ the temperature profile}, and then ramped back down to the initial room temperature
