1. In the thermаl prоcessing оf semicоnductor mаteriаls, annealing is accomplished by heating a silicon wafer according to a temperature-time recipe and then maintained in a fixed elevated temperature for a prescribed period of time As shown, the wafer is in an evacuated chamber whose walls are maintained at 27 oC and within which heating lamps maintain a radiant flux at its upper surface. The wafer is 0.78 mm thick and has thermal conductivity of 30 W/m.K. For W/m2, the temperature on its lower surface is measured at 997 0C. To avoid warping the wafer and inducing slip planes in the crystal structure, the temperature difference across the thickness of the wafer must be less than 3 0C. What is the emissivity of the wafer,
