A liquid supply device includes: a storage tank configured to store a processing liquid including a first processing liquid (sulfuric acid) and a second processing liquid (hydrogen peroxide solution); a circulation path having a first pipeline through which the processing liquid passes in a horizontal direction, and configured to circulate the processing liquid stored in the storage tank; a branch path configured to supply the processing liquid to a processing unit; and a branching part having an opening for allowing the processing liquid to flow out from the first pipeline to the branch path, wherein the opening is formed in the branching part and formed below a periphery of the first pipeline when the first pipeline is viewed in section.

Liquid supply device and liquid supply method

There is disclosed a hollow tube body used for a liquid feeding member and deformable by pressurization, wherein: an axial cross-section of the tube body has two opposing long side parts and two opposing short side parts; four corner portions formed by the long side parts and the short side parts each have a shape curved to protrude outward; each of the long side parts has a recessed part recessed inward and continuing from the corner portions; and a portion other than the corner portions of each of the short side parts is in a flat shape.

Tube body and pumping device

A recovery route returns, to a retaining tank, mixed solution supplied to a substrate processing unit. A discarding route discards the supplied mixed solution to a place other than the retaining tank. A switching controller causes the supplied mixed solution to flow into the discarding route during a time interval until a first time interval has elapsed from a time point when the substrate processing unit starts to supply the mixed solution; causes the supplied mixed solution to flow into the recovery route during a time interval until a second time interval, which is decided based on a predetermined recovery rate, has elapsed after the first time interval elapses; and causes the supplied mixed solution to flow into the discarding route during a time interval until supply of the mixed solution has been ended from a time point when the second time interval elapses.

Substrate processing apparatus and substrate processing method

A liquid processing apparatus includes a processing unit, a first supply route, a first device, a second supply route, a second device, a housing, and an external housing. The processing unit processes a substrate by using processing liquid including first and second processing liquids. The first supply route is for supplying the first processing liquid to the processing unit. The first device is for supplying the first processing liquid to the first supply route. The second supply route is for supplying the second processing liquid to the processing unit. The second processing liquid has higher temperature than the first processing liquid. The second device is for supplying the second processing liquid to the second supply route. The housing accommodates the processing unit. The external housing accommodates the first and second devices, and is adjacent to the housing. The external housing includes a partition wall between the first and second devices.

Liquid processing apparatus

A substrate liquid processing apparatus includes a tank; a circulation line; a processing unit connected to the circulation line through a branch line and configured to perform a liquid processing on a substrate using a processing liquid flowing through the circulation line; a processing liquid producing mechanism configured to produce the processing liquid by mixing at least two kinds of raw material liquids supplied from respective raw material liquid sources at a controlled mixing ratio; a concentration measuring device configured to measure a concentration of the processing liquid flowing through the circulation line and a concentration of the processing liquid flowing through the processing liquid supply line; and a control device configured to control the processing liquid producing mechanism based on the measured concentrations of the processing liquid.

A disclosed substrate processing apparatus comprises a heat exchange plate configured to heat and/or cool the substrate; plural protrusions provided on the heat exchange plate so as to allow the substrate to be placed on the plural protrusions, leaving a gap between the substrate and the heat exchange plate; a suction portion configured to attract the substrate onto the plural protrusion by suction through plural holes formed in the heat exchange plate; and a partition member that is provided on the heat exchange plate and lower than the plural protrusions, wherein the partition member is configured to divide the gap into two or more regions including at least one of the holes so that at least one of the two or more regions is two-dimensionally closed by the partition member.

Substrate processing apparatus, substrate processing method, and computer-readable storage medium

A non-transitory storage medium stores software for performing a rinsing process on a substrate, after a developing process is performed on a light-exposed pattern disposed thereon. The sequence includes throwing off a developing solution from the substrate after development; supplying a water-based cleaning liquid onto the substrate; supplying a surfactant-containing rinsing liquid onto the substrate to replace liquid remaining on the substrate with the surfactant-containing rinsing liquid; and rotating the substrate to expand and throw off the surfactant-containing rinsing liquid on the substrate.

Non-transitory storage medium for rinsing or developing sequence

A rinsing method for performing a rinsing process on a substrate, after a developing process is performed on a light-exposed pattern disposed thereon, includes a step (STEP) of throwing off a developing solution from the substrate after development; a step (STEP) of supplying a water-based cleaning liquid onto the substrate; a step (STEP) of supplying a surfactant-containing rinsing liquid onto the substrate to replace liquid remaining on the substrate with the surfactant-containing rinsing liquid; and a step (STEP) of rotating the substrate to expand and throw off the surfactant-containing rinsing liquid on the substrate.
