Abstract: First irradiation which causes an emission output from a flash lamp to reach its maximum value over a time period in the range of 1 to 20 milliseconds is performed to increase the temperature of a front surface of a semiconductor wafer from a preheating temperature to a target temperature for a time period in the range of 1 to 20 milliseconds. This achieves the activation of the impurities. Subsequently, second irradiation which gradually decreases the emission output from the maximum value over a time period in the range of 3 to 50 milliseconds is performed to maintain the temperature of the front surface within a ±25° C. range around the target temperature for a time period in the range of 3 to 50 milliseconds. This prevents the occurrence of process-induced damage while suppressing the diffusion of the impurities.

Abstract: A waste heat controller controls waste heat quantity of an engine according to a required heat quantity along with a heat-utilize requirement. When the heat-utilize requirement is generated, a fuel-increase-rate indicating a fuel increase quantity is computed. A reference fuel-increase-rate is established to be compared with the fuel-increase-rate. Based on this comparison result, it is determined whether the waste heat increase control will be executed.

Abstract: A silicon wafer is heated from an initial pre-heating temperature (T0) up to a first annealing temperature (T1) by a rapid heating up step using an IR lamp. A first annealing is executed at the first annealing temperature (T1). Successively, while the silicon wafer is maintained at a second annealing temperature (T2) lower than the first annealing temperature (T1), a second annealing step is executed by a resistive heating furnace. A thermal oxidation can be executed as the second annealing step. To do so, an equipment for manufacturing a semiconductor device in the present invention is provided with: a heating device having an IR lamp and a resistive heater; an annealing tube having on a surface thereof a plurality of concave portions in such a way that each bottom approaches a central line; a resistive heater wrapped around this annealing tube; and an IR lamp movably inserted into and pulled out from the concave portion from the external.

Abstract: In a shaft furnace for burning limestone or similar raw materials, gaseous, liquid or solid fuels are supplied through fuel supply pipes to the burning zone of a furnace shaft. To permit the simultaneous supply of at least two different fuels, the fuel supply pipes are arranged as multiple fuel lances. The fuel lances extend inwardly from the shaft furnace wall through the preheating zone into the first part of the burning zone. The fuel lance is a double tube member made up of an inner tube laterally enclosed by an outer tube forming an inner fuel supply passageway and an outer annular fuel supply passageway. Two separate fuels can be introduced into the burning zone, one flowing through the inner passageway and the other through the outer annular passageway. The two different fuels can be supplied in varying proportions without any changeover operations.
