Abstract: PURPOSE: To remove a photoresist, using ozone-dissolved water at high concentration and a high liquid temperature, in a photoresist remover. CONSTITUTION: A semiconductor wafer 1 is heated, using an infrared lamp 16 immediately prior to discharging the ozone-dissolved water at normal temperature manufactured with an ozone-dissolved water manufacture device 14 onto the semiconductor wafer 11 placed on a stage 12 via a discharge nozzle 13. According to this method, the ozone-dissolved water can be kept at low temperature just before being discharged onto the semiconductor wafer. That is, the ozone-dissolved water can be kept at high temperature just before discharge. When this ozone-dissolved water in high concentration is discharged to the semiconductor wafer, the liquid temperature of the ozone-dissolved water rises and the decomposition of the ozone occurs, because the semiconductor wafer is heated in advance to a prescribed temperature. Due to this decomposition of ozone, chemical reaction between the ozone and a photoresist is accelerated. Therefore, the etching speed of the photoresist goes up, and in turn, this system can shorten the time required for removal of the photoresist.
