First, a worker cleaning liquid discharge pressure from the input key nozzle tip 30 from the operation panel 14, for example, generally set input a desired numerical value between 20 kg / cm 2 of 100 kg / cm 2 (Step 1) . Then, the value of the desired discharge pressure of the cleaning liquid is stored in the memory as a storage unit in the CPU 12 (step 2), and
The drive air pressure of the pump is set in the pump drive regulator 14 through the CPU 12 (step 3). And
The cleaning liquid is ejected toward the detection surface of the sensor 11 from the nozzle tip 30 of the nozzle 20 located at a position deviated from above the substrate W (step 4). Then, the discharge pressure of the cleaning liquid is detected by the sensor 11, and the value of the discharge pressure of the cleaning liquid becomes CP.
It is transmitted to U12 (step 5). In the CPU 12,
The value of the discharge pressure of the cleaning liquid stored in the memory in the CPU is compared with the value of the discharge pressure of the actual cleaning liquid detected by the sensor 11, and the value of the actual discharge pressure of the cleaning liquid matches the set value. It is determined whether or not (step 6). Here, when the actual value of the discharge pressure of the cleaning liquid is different from the set value, the process returns to step 3 and the discharge pressure of the cleaning liquid discharged from the nozzle tip 30 becomes a desired discharge pressure.
The pump drive air pressure of the pump drive regulator 14 is adjusted. On the other hand, if it is determined that the actual value of the discharge pressure of the cleaning liquid matches the set value, the process proceeds to step 7. In step 7, in the discharge nozzle 20, the cleaning liquid discharged from the nozzle chip 30 is folded back from the point S on the sensor 11 through the center point C on the substrate W to the outside of the substrate as shown in FIG. Up to the point R, the substrate W is reciprocally moved horizontally so that it is supplied while drawing an arc locus, sucked and held by the holding table 10, and the high-pressure cleaning liquid is supplied onto the substrate W that is rotating. Is washed (step 7). Then, the process proceeds to step 8 and it is determined whether or not the cleaning is completed for all the substrates. If it is determined that the cleaning is not completed, the processes of steps 5 to 8 are repeated until cleaning of all the substrates is completed. On the other hand, when the cleaning is completed for all the substrates, the operation is finished. In the present embodiment, the discharge pressure of the cleaning liquid is detected for each substrate and the discharge pressure of the cleaning liquid is adjusted.However, for example, the discharge pressure of the cleaning liquid is adjusted for each set number of substrates or each lot. May be adjusted.
