This invention provides a gas equalization assembly, a semiconductor process chamber, and a semiconductor thin film deposition apparatus. The gas equalization assembly includes: a gas equalization chamber, a servo motor, and a gas equalization plate, a gas equalization fan, and a spray plate located within the gas equalization chamber. The gas equalization chamber is a hollow cavity with a top wall having an air inlet and a mounting hole, and an open bottom end. The gas equalization plate is used for zoned diffusion of the incoming gas. The upper end of the servo motor is fixed above the top wall of the gas equalization chamber, and its lower end's rotating shaft extends through the mounting hole into the interior of the gas equalization chamber. The gas equalization fan is configured to rotate synchronously with the rotating shaft to mix, pressurize, and uniformly deliver the gas downwards. The spray plate is located below the gas equalization fan and covers the bottom end of the gas equalization chamber. The spray plate has multiple air jets arranged in an array to uniformly spray the gas from the gas equalization chamber. This effectively improves the uniformity and consistency of the reactant gas entering the reaction chamber, thereby improving the uniformity of thin film deposition.
