A data processing method includes a step of obtaining evaluated values of the time-series data by comparing the time-series data with reference data, a step of classifying the evaluated values into a plurality of levels, a step of displaying an evaluation result screen including a display area including a first graph showing an occurrence rate of each level of the evaluated values, the evaluation result screen including the display area with respect to each of the two or more processing units. A history screen displaying a history in which the evaluated values have been obtained and a trend screen including graphs showing temporal change in the evaluated values in addition to the evaluation result screen is hierarchically displayed. A mark is attached at a position corresponding to a processing result selected in the history screen in a graph in the trend screen.

Data processing method, data processing apparatus, and recording medium with data processing program recorded thereon

A data processing method includes a step of obtaining scores of time-series data by comparing the time-series data with reference data in order to process time-series data acquired in a substrate processing apparatus having one or more processing units, a step of classifying the scores into a plurality of levels, and a step of displaying an evaluation result screen including a display area including a graph showing an occurrence rate of each level of the scores, the number of occurrences of each level, and a graph showing temporal change in the number of occurrences of a worst level of the scores when substrates have been processed through a predetermined method with respect to each of the two or more processing units. Accordingly, a data processing method through which a state of the substrate processing apparatus can be easily ascertained is provided.

A substrate processing apparatus includes a substrate holder, and a discharge head for peripheral area from which a fluid is discharge toward a surface peripheral area of the substrate held on the substrate holder. The discharge head for peripheral area includes multiple nozzles, and a support part that supports the nozzles integrally. The nozzles include a processing liquid nozzle from which a processing liquid is discharged toward the surface peripheral area, and a gas nozzle from which gas is discharged toward the surface peripheral area. The gas nozzle is placed upstream of a rotative direction of the substrate relative to the processing liquid nozzle.

Substrate processing apparatus and substrate processing method

A substrate processing apparatus includes: a spin base rotatable in a horizontal plane about a centered rotary axis; a holder to hold a substrate above the spin base; a lower surface processing unit to discharge a processing liquid toward a lower surface of the substrate held by the holder. The holder includes: a plurality of first abutting members that abut the substrate from a position obliquely below said substrate and that hold the substrate in a horizontal posture in a position spaced from an upper surface of said spin base; a plurality of second abutting members that abut the substrate from a position lateral to said substrate and that hold said substrate in a horizontal posture in a position spaced from the upper surface of said spin base. A switching mechanism switches between a first holding condition state where the first abutting members hold the substrate and a second holding condition state where the second abutting members hold the substrate; wherein, in the second holding condition state, the first abutting members are spaced from the substrate, and in the first holding condition state, an upper surface of the substrate is in a position above an upper end surface of each of the first and second abutting members are spaced from the substrate.

A data processing method includes a step of obtaining scores of time-series data by comparing the time-series data with reference data in order to process time-series data acquired in a substrate processing apparatus having one or more processing units, a step of classifying the scores into a plurality of levels, and a step of displaying an evaluation result screen including a graph showing an occurrence rate of each level of the scores, the number of occurrences of each level, and a graph showing temporal change in the number of occurrences of a worst level of the scores when substrates have been processed through a predetermined method with respect to the processing units. Accordingly, a data processing method through which a state of the substrate processing apparatus can be easily ascertained is provided.

A substrate processing apparatus includes: a substrate holder to hold a substrate in a horizontal posture while rotating the substrate about a vertical rotary axis passing through the center of a plane of the substrate; a guard member having a shape extending along at least part of a surface peripheral area of the substrate, the guard member being placed in a position close to the surface peripheral area of the substrate held by the substrate holder in a noncontact manner; a cup being a tubular member with an open top end, the cup being provided so as to surround the substrate held by the substrate holder and the guard member together; and a nozzle from which a processing liquid is discharged to the surface peripheral area of the substrate held by the substrate holder. The nozzle is placed on a side opposite the cup with respect to at least part of the guard member.
