Abstract:
A technology that can clean a bottom surface of a dresser while inhibiting a cleaning solution discharged from a cleaning nozzle from splashing in a direction of a polishing pad. A polishing apparatus 1 includes a polishing table 2, a top ring 3, a dresser 10, at least one cleaning nozzle 20, and a dresser rotation mechanism 32. The at least one cleaning nozzle discharges a cleaning solution Lq in a fan shape and in a direction away from a polishing pad Pd, and an intersection point IP where a discharge central axis XL2 of the cleaning solution intersects with a bottom surface 11 of the dresser is positioned closer to the at least one cleaning nozzle than a center line CL1 of the bottom surface of the dresser. The at least one cleaning nozzle discharges the cleaning solution such that a part of the cleaning solution discharged from the cleaning nozzle and contacting the bottom surface of the dresser moves and passes through the center C1 of the bottom surface of the dresser.
Abstract:
Provided is a substrate holder where an effect of a pressure of a plating solution can be suppressed. A substrate holder includes first and second holding members for sandwiching a substrate. The first holding member includes: a support base; a movable base for supporting the substrate; and a biasing mechanism disposed between the support base and the movable base, and biasing the movable base in a direction along which the movable base is separated from the support base. The second holding member includes a protruding portion brought into contact with the substrate so as to seal the substrate. A biasing force of the biasing mechanism which is applied to a region or a position of the movable base differs from a biasing force of the biasing mechanism which is applied to another region or at another position of the movable base.
Abstract:
A substrate holder capable of being used in both single-side plating and double-side plating is required. Disclosed is a substrate holder for holding a substrate to be plated. The substrate holder includes a first frame having a first opening for exposing one surface of the substrate and a second frame having a second opening for exposing the other surface of the substrate, and the substrate is sandwiched between the first frame and the second frame. The substrate holder further includes a dummy substrate which is detachably disposed between the first frame and the substrate and formed of a material that at least direct current does not substantially flow therein. At least a part of the dummy substrate is in contact with at least a part of the one surface of the substrate, and the dummy substrate protects the one surface of the substrate from a plating solution.
Abstract:
To provide a substrate holder having a new positioning structure, which does not use a plate spring, and a plating apparatus using this substrate holder. A substrate holder is provided. This substrate holder has a first holding member having a first surface configured to contact with a substrate, and a second holding member for sandwiching and holding the substrate together with the first holding member. The first holding member has a positioning member for positioning the substrate in contact with the first surface at a prescribed position of the first surface. The positioning member is configured to move between a first position where the substrate is to be positioned at the prescribed position of the first surface, in contact with a peripheral edge part of the substrate, and a second position not in contact with the substrate. The second holding member has a driving member configured to cause the positioning member to be positioned at the first position, at the time when holding the substrate by the first holding member and the second holding member.
Abstract:
One object of this application is to provide an advanced substrate holder including a clamper. A substrate holder for holding a substrate by interposing the substrate between frames is disclosed. The substrate holder includes a front frame, a rear frame, and one or a plurality of clampers. Each of the clampers includes a hook portion including a hook base and a hook main body, and a plate including at least one claw. At least one of the clampers includes the plate including a first claw for a lock and a second claw for a semi-lock.

Abstract:
A vacuum pump connecting apparatus has a first vibration absorbing portion and a second vibration absorbing portion which are connected to an evacuation connection portion so as to dispose the first vibration absorbing portion and the second vibration absorbing portion opposite each other via the evacuation connection portion. The first vibration absorbing portion is connected to an intake port of a vacuum pump at a second end of the first vibration absorbing portion opposite to a first end of the first vibration absorbing portion connected to the evacuation connection portion. The first vibration absorbing portion and the second vibration absorbing portion are elastic bellows. A vacuum pump connecting apparatus has a rigid coupling member is connected to a second end of the second vibration absorbing portion opposite to a first end of the second vibration absorbing portion connected to the evacuation connection portion.
Abstract:
Provided is a substrate holder including a first holding member and a second holding member configured to sandwich and fix a substrate, wherein the first holding member includes a first holding member body, and a clamp provided on the first holding member body, the clamp being rotatable about a shaft extending parallel to a surface of the first holding member body, or being reciprocable in a direction intersecting with the surface of the first holding member body, the second holding member includes a second holding member body, and the clamp is capable of engaging with the second holding member in a state where the first holding member body and the second holding member body are brought into contact with each other, to fix the second holding member to the first holding member.
