Abstract
A semiconductor manufacturing apparatus according to the present embodiment includes a tank, a heater, a bubble supplier, a sensor and a controller. The tank stores a chemical solution for processing a substrate. The heater heats the chemical solution. The bubble supplier supplies bubbles to the chemical solution in the tank. The sensor detects at least one of a concentration of the chemical solution, a water concentration of the chemical solution, specific gravity of the chemical solution and a vapor concentration of a gas discharged from the tank. The controller controls the supply of bubbles by the bubble supplier based on a detection result of the sensor.
