Temperature Difference and Heat Transfer

Whenever there is a flow of heat flux resulting from a temperature gradient within the material or between two materials, there is heat transfer. Heat transfer primarily arises due to temperature differences between two bodies or within bodies. The term temperature gradient denotes temperature differences or variation of temperature due to change in some quantity. The fundamental use of the concept of temperature is found in the zeroth law of thermodynamics.

A gate oxide is grown in 640 torr of water vapour at 1050o C. The oxide is grown on a bare (100) silicon wafer. The oxidation time is 2 mins. i) Assuming the tau (τ) value is zero, use the Deal–Grove model to predict the oxide thickness. Do not use design curves. For simplicity, when estimating B and B/A, assume the values are a linear function of temperature, rather than the actual exponential function. ii) When this process is run, the measured oxide thickness is 0.1 µm, but the oxidation rate after 2 mins agrees with the B/A ratio.
