  • Patent number: 11380562
    Abstract: A substrate processing apparatus includes a substrate holder, a rotating mechanism, a processing liquid discharge unit, and a gas discharge unit. The processing liquid discharge unit discharges a liquid flow of a processing liquid such that the liquid flow comes into contact with a landing position in a rotation path of a peripheral portion of an upper surface of the substrate being rotated. The gas discharge unit discharges a first gas flow of an inert gas from above toward a first position upstream from the landing position in a direction of rotation of the substrate in the rotation path, and discharges a second gas flow of the inert gas from above toward a second position upstream from the first position in the direction of rotation of the substrate in the rotation path. The kinetic energy of the second gas flow is lower than the kinetic energy of the first gas flow.

  • Patent number: 10790151
    Abstract: Provided is a substrate processing method for processing a substrate. The substrate processing method includes a step of processing the substrate with a phosphoric acid liquid, a step of processing the substrate with a rinsing liquid, and a step of processing the substrate with a chemical liquid containing ammonia. After the substrate is processed with the rinsing liquid, the step of processing the substrate with a chemical liquid removes a portion of thickness of a film in a depth direction of a phosphorus diffusion region from the phosphorus diffusion region formed in the substrate when the substrate is processed with the phosphoric acid liquid.
