Abstract:
A method of polishing a substrate having a film is provided. The method includes: performing polishing of the substrate in a polishing section; transporting the polished substrate to a wet-type film thickness measuring device prior to cleaning and drying of the substrate; measuring a thickness of the film by the wet-type film thickness measuring device; comparing the thickness with a predetermined target value; and if the thickness has not reached the predetermined target value, performing re-polishing of the substrate in the polishing section prior to cleaning and drying of the substrate.

Abstract:
The present invention relates to a polishing method and a polishing apparatus for polishing a substrate, such as a wafer. The present invention further relates to a computer-readable storage medium storing a program for causing the polishing apparatus to perform the polishing method. The polishing method includes: rotating a polishing table (3); and polishing a substrate (W) by pressing the substrate (W) against a polishing surface (2a). Polishing the substrate (W) includes a film-thickness profile adjustment process and a polishing-end-point detection process. The film-thickness profile adjustment process includes adjusting pressing forces on the substrate (W) against the polishing surface (2a) based on a plurality of film thicknesses, and determining a point in time at which a film-thickness index value has reached a film-thickness threshold value. The film-thickness index value is determined from at least one of the plurality of film thicknesses. The polishing-end-point detection process includes measuring a torque for rotating the polishing table (3) and determining a polishing end point based on the torque.
Abstract:
As an aspect of the present invention, a cleaning apparatus for cleaning member has a holding part 100 holding a cleaning member assembly 1 having a cleaning member 90; an inner cleaning liquid supply part 110; an outer cleaning liquid supply part 120; and a control part 350 controlling the substrate cleaning apparatus to perform a first process in which the cleaning member 90 is pressed against a dummy substrate Wd at a first pressure and the outer cleaning liquid supply part 120 supplies the cleaning liquid to the dummy substrate Wd, and to perform a second process in which the cleaning member 90 is separated from the dummy substrate Wd or is pressed against the dummy substrate Wd at a second pressure which is equal to or less than the first pressure and the inner cleaning liquid supply part 110 supplies the cleaning liquid.
Abstract:
A cleaning device includes: a substrate rotation mechanism that holds and rotates a substrate around center axis thereof; a first single-tube nozzle that discharges first cleaning liquid toward a top surface of the substrate; and a second single-tube nozzle that discharges second cleaning liquid toward the top surface of the substrate. The first single-tube nozzle and the second single-tube nozzle are disposed such that the second single-tube nozzle discharges the second cleaning liquid in a forward direction of a rotation direction of the substrate at a position farther away from the center of the substrate than a landing position of the first cleaning liquid, and a part is generated in which liquid flow on the top surface of the substrate after landing of the first cleaning liquid and liquid flow on the top surface of the substrate after landing of the second cleaning liquid are combined.
