To provide a device wafer polishing pad which improves uniformity of a device wafer conductive layer within a wafer surface and performs stable electrochemical mechanical polishing for a long period of time. All the electrolytic solution storage sections (F) from the inner diameter side to the outer diameter side are arranged on a polishing pad (60) so that a relational expression of 45/SQRT(R)
It is possible to provide a device wafer polishing pad, a polishing body, a polishing tool constituting body, and a polishing method which can polish a conductive layer for forming device wafer wiring without damaging the conductive layer. An electrolyte cell (C1) for electrical communication is formed by electro-chemically connecting a conductive layer (D1) to an anode electrode (63) via an electrolyte solution (E) so as to make the conductive layer (D1) an anode. An electrolyte cell (C2) for polishing is formed by electro-chemically connecting the conductive layer (D1) to a cathode electrode (65) via the electrolyte solution (E) independently of the electrolyte cell (C1) for electrical communication. Thus, the conductive layer (D1) is polished electro-chemical-mechanically.
An apparatus for substrate processing in which the step of removing a substance to be treated is not complicated, the temperatures of the substance to be treated and a wet ozonous gas are easily controlled, and even a photoresist having ions implanted in a high dose can be removed. An inert gas (2) is bubbled into a treating liquid (3) to produce a wet inert gas (4). The wet inert gas (4) is mixed with ozone gas (5) to produce a wet ozonous gas (6). The wet ozonous gas (6) is heated to 120-200°C and supplied to a photoresist (7a) heated to 180-350°C. Thus, the photoresist (7a) is ashed while instantly vaporizing the treating liquid (3) which has adhered to the photoresist (7a).
Provided are a substrate treatment apparatus (1) and a substrate manufacturing method by which process management is facilitated and the structure is simplified. A substrate (W) is stored in a treatment tank (2) to be impregnated with a treatment solution (F), the treatment solution (F) sucked from the inside of the treatment tank (2) is heated up to 55°C by a heater (6), then, an ozone bubble treatment solution (FB) is generated by mixing ozone gas. Then, the ozone bubble treatment solution (FB) is supplied to a film (Wa) (subject to be treated) in a high-speed water flow status by jetting the ozone bubble treatment solution by an ozone bubble jetting section (9).
Provided is a device wafer polishing pad by which uniformity of a device wafer conductor layer is improved within a wafer plane and stable electrochemical mechanical polishing can be performed for a long time. Electrolytic solution storing sections (F) are arranged on a polishing pad (60) so that the openings become smaller in width and deeper toward the one arranged on the outer circumference side. A conductor layer (D1) of a device wafer (D) is brought into contact with the liquid surface of an electrolytic solution (E) in the electrolytic solution storing section (F), an electrolysis cell (C) is formed by applying a voltage, and the conductor layer (D1) is electrochemically and mechanically polished by using the electrolysis cell (C) and a polishing member layer (62).
Disclosed is a contact conductor for wafer polishing which enables to polish a conductor layer of a device wafer without causing damages thereto. Also disclosed are a polishing pad for semiconductor device wafers and a method for producing a semiconductor. Specifically disclosed is a conduct conductor (610) which is brought into electrical and mechanical contact with a conductor layer (D1). The conduct conductor (610) is mainly composed of a flake graphite material while containing 5-40 wt% of a synthetic resin material. By forming the conduct conductor (610) in such a manner that the spaces between flake graphite fine particles are filled with the resin, permeation of the electrolyte solution is prevented, thereby reducing separation of the flake crystals caused by generation of a gas.
Disclosed is a polishing pad for device wafers which enables to electrochemically mechanically polish a conductor layer of a device wafer by using an electrolysis cell while improving planarity and in-plane uniformity of the wafer. Specifically, an electrochemical protective film (passivation film) formed on a conductor layer (D1) can be mechanically removed by fixing a polishing pad (60) to a polishing device (50) and relatively moving a polishing member layer (62) with respect to the conductor layer (D1), while pressing the polishing member layer (62) onto the conductor layer (D1). Meanwhile, an electrolysis cell is constituted of the conductor layer (D1), a conductive sheet layer (66) and an electrolyte solution (E), thereby electrochemically dissolving and removing the conductor layer (D1).
