Abstract: A contact is disposed to come into contact with a metal layer formed on a substrate being treated, the contact being in contact with a surface being treated from an opposite surface through a through hole present in a substrate. Alternatively, a contact is disposed to come into contact with a metal layer formed on a substrate, the contact coming into contact at an approximate center of the substrate. Alternatively, a plurality of needle bodies are disposed to be in electrical contact with a metal layer of a substrate being treated, thereby power supply for electrolytic polishing/plating to a substrate being treated being implemented, without restricting to a periphery of a substrate, from a plurality of points on a surface thereof. Due to any one of these, liquid treatment equipment enables to improve uniformity in plane of an electric current sent to a surface being treated and of liquid treatment.

Abstract: A thermal insulator can change a heat insulation characteristic partially with a simple structure. The thermal insulator is divided into a plurality of parts in accordance with a temperature of a heat source which is insulated by the thermal insulator. The plurality of parts are formed of different honeycomb structures, respectively, so as to provide different heat insulation characteristics. The plurality of parts may be formed by different materials, or a shape or dimension such as a cell pitch of the honeycomb structure may be varied. Heat is collected from air within the honeycomb cells, and is transferred to other parts for heating.

Abstract: Plating apparatus and plating method that can plate more uniformly on a processing surface of a workpiece are provided. The plating apparatus is comprised of a plating solution bathe which is provided with a first electrode held in a state soaked in a plating solution; a workpiece holding mechanism which holds a workpiece to contact its processing surface to the plating solution; and a contact member, disposed in the workpiece holding mechanism, that electrically contacts with the circumferential edge of the workpiece so to form a conductive layer on the workpiece surface as a second electrode. The contact member is divided along the circumferential direction of the workpiece with which they are electrically contacted. Thus, even if the contact resistance between each section of the contact member with the workpiece is variable, it is possible to adjust the plating electric current for each section of the contact member.

Abstract: A plating system is composed of a transfer device for performing transfer of a wafer, a plating unit and a washing/drying unit provided around the transfer device. Each unit is structured to be detachable from the plating system. The plating unit is divided into a wafer transfer section and a plating section by a separator, and atmosphere of each section is independently set.

Abstract: A mist trap mechanism and method for a plating apparatus, which can provide an improved mist removing effect by a simple structure, are provided. A gas discharge passage is formed to connect the space in a plating chamber and space outside of the plating chamber and provided with a liquid spouting portion and a solid wall. The discharge gas collides with the liquid spouted from the liquid spouting portion, and the discharge gas collides with the solid wall which has its surface wetted with the liquid spouted from the liquid spouting portion. Such a two-staged collision of the discharge gas effectively takes the mist contained in the discharge gas into the liquid. A liquid recovery portion is disposed in connection with the gas discharge passage to collectively catch the mist in a state captured by the liquid.

Abstract: Liquid treatment units are disposed in multi-tiers surrounding a main-arm 35. Among liquid treatment units, plating units M1 through M4 are disposed on a lower tier side, and a unit for post-treatment process such as a cleaning unit 70 where a cleaner atmosphere is necessary is disposed on an upper tier side. Thereby, an improvement in an area efficiency and the formation and maintenance of a clean atmosphere can be simultaneously obtained.

Abstract: Between a wafer and a holder holding a wafer, a seal member is disposed so that a contact surface is formed in an approximate plane, and an inner periphery surface is formed in an approximate plane and approximately vertical to a contact surface. The seal member, in a sealed state, has a brim portion of a radius of curvature of 0.5 mm or less at a boundary portion between an inner periphery surface of a seal member and a contact surface. Due to a brim portion, a gap between a contact surface of a seal member and a surface being plated of a wafer W can be made smaller, resulting in reducing bubbles entering in a gap.
