Abstract: A joint portion evaluating method for measuring and evaluating a joint state of a joint portion at which a first joint body and a second joint body are joined together, the joint portion evaluating method including the steps of: acquiring as a reference value a capacitance value of the joint portion in a reference measurement state serving as a reference for measurement conditions; changing a measurement state from the reference measurement state and acquiring as a measured value a capacitance value of the joint portion in a changed measurement state arising after the change of the measurement state; deriving as a measurement evaluation value a value obtained by referencing the measured value with the reference value; and performing an evaluation based on the derived measurement evaluation value.

Abstract: An object is to allow for simple measurement of a bump height. There is provided a device for measuring a bump height comprising: a light sensor provided with a light source and a light-receiving element and configured to irradiate a substrate including a seed layer, a resist layer formed on the seed layer and a bump formed in an opening of the resist layer, with light emitted from the light source and to detect reflected light that is reflected from the seed layer via the resist layer and reflected light that is reflected from the bump, by the light-receiving element; and a control device configured to calculate a height of the bump relative to the seed layer, based on the reflected light from the seed layer and the reflected light from the bump and to subtract an error caused by a refractive index of the resist layer from the height of the bump calculated based on the reflected lights, so as to correct the height of the bump.

Abstract: There is provided the substrate holder for holding a substrate comprising a first holding member, a second holding member, a sealing member, a pin, a ring, and a moving mechanism. The sealing member forms a sealed space inside the substrate holder. The pin is fixed to one of the first holding member and the second holding member. The ring is disposed on another of the first holding member and the second holding member. The ring engages with the pin. The moving mechanism circumferentially moves the ring. The pin and the ring are engaged with one another to fix the first holding member and the second holding member to one another. The pin and the ring are disposed inside the sealed space.

Abstract: A method capable of removing a liquid from a seal of a substrate holder so as to prevent contact between the liquid and an electrical contact of the substrate holder is provided. The method includes: immersing the substrate in a plating solution, with a seal and an electrical contact of the substrate holder in contact with the substrate; applying a voltage between the substrate and an anode in the presence of the plating solution to plate the substrate; pulling up the plated substrate from the plating solution; separating the seal from the plated substrate; and forming a flow of gas passing through a gap between the plated substrate and the seal, the flow of gas being directed from an inside to an outside of the substrate holder.

Abstract: The present invention relates to a substrate holding apparatus for holding and pressing a substrate against a polishing surface. The substrate holding apparatus includes a top ring body for holding the substrate, an elastic pad for contacting the substrate, and a support member for supporting the elastic pad. The substrate holding apparatus further includes a contact member mounted on a lower surface of the support member and disposed in a space formed by the elastic pad and the support member. The contact member has an elastic membrane for contacting the elastic pad. A first pressure chamber is defined in the contact member, and a second pressure chamber is defined outside of the contact member. The substrate holding apparatus also includes a fluid source for independently supplying a fluid into, or creating a vacuum in, the first pressure chamber and the second pressure chamber.
