SUPPLY POWER ADJUSTING APPARATUS AND SEMICONDUCTOR MANUFACTURING APPARATUS |
摘要 |
A semiconductor manufacturing apparatus for performing heat treatment by carrying a substrate holder, on which a plurality of substrates are loaded, into a reacting furnace. The semiconductor manufacturing apparatus is provided with a heater arranged on a circumference of the reacting furnace, and a supply power adjusting apparatus for adjusting a supplying power to the heater. The supply power adjusting apparatus is composed of a power IGBT converter for converting an alternating voltage from an alternating power supply into an alternating power in accordance with the frequency of a control signal and supplying the heater with the alternating power, and a regenerating IGBT converter for regenerating a back electromotive force generated by switching operation of the IGBT converter and returning the back electromotive force to the alternating power supply.
