[0010] [Figure 1] FIG. 1 is a schematic diagram illustrating an example of a chemical mechanical polishing apparatus. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] (First embodiment: chemical mechanical polishing apparatus) The chemical mechanical polishing apparatus of the present disclosure includes one or more components having a surface treatment layer formed using a fluoropolyether group-containing compound.

[0012] According to the present disclosure, a new chemical mechanical polishing apparatus can be provided.

[0013] In the chemical mechanical polishing method, typically, a polishing slurry containing abrasive grains such as silicon dioxide and a basic compound is used. When such a polishing slurry adheres to the surface of the chemical mechanical polishing apparatus, it may solidify and affect the polishing performance. In a preferred embodiment, the chemical mechanical polishing apparatus of the present disclosure has good workability of the polishing slurry (e.g., resilience and / or removability of the polishing slurry), and in a more preferred embodiment, the workability is good even after a time has passed since the polishing slurry was adhered. Although the present disclosure should not be interpreted as being limited to a particular theory, the reason why such an effect is achieved in the chemical mechanical polishing apparatus of the present disclosure is considered to be as follows.

[0014] That is, in the chemical mechanical polishing apparatus of the present disclosure, one or more of the components have a surface treatment layer formed by using a compound containing fluoropolyether groups. Therefore, it is considered that the adhesion of polishing slurry can be suppressed, and the interaction with the solidified matter of polishing slurry can be suppressed, and the workability, especially the workability after time has passed, can be improved. On the other hand, in the conventional surface treatment layer, fluorinated products of fluorocarbon polymers and silicone rubber are used, and the components that can be surface treated may be limited, and it may be difficult to sufficiently suppress the adhesion of polishing slurry.

[0015] The chemical mechanical polishing apparatus disclosed herein typically comprises a rotatable platen, a polishing pad placed on the platen, a polishing head placed on the polishing pad, a polishing head arm portion that fixes the polishing head, a polishing slurry supply portion, a polishing portion cover, and a discharge groove.

[0016] The platen is typically formed in a disk shape and is connected to a rotating shaft disposed below the platen. The platen rotates as the rotating shaft rotates. A polishing pad is fixed to the top of the platen, and a polishing slurry is supplied onto the polishing pad from a polishing slurry supply unit.

[0017] The polishing head may be formed in a disk shape having a smaller diameter than the base plate and may be connected to an arm portion of the polishing head disposed above the polishing head. The arm portion may include a rotating shaft (not shown), and the rotating direction of the rotating shaft of the arm portion may be opposite to the rotating direction of the rotating shaft of the base plate.

[0018] The polishing head may be provided with a head body, a pressing member for pressing the object to be polished downward (to the polishing pad), and a buffer member disposed between the object to be polished and the pressing member.

[0019] The polishing unit cover may be disposed on the outer periphery of the surface plate, and a drain groove may be disposed between the polishing unit cover and the surface plate.

[0020] In one embodiment, in this chemical mechanical polishing apparatus, the object to be polished can be attached to the polishing head. The object to be polished rotates together with the polishing head, and the polishing head presses one side of the object to be polished onto the rotating platen with a predetermined pressure while rotating. In addition, a polishing slurry is supplied from a polishing slurry supply unit onto the platen (on the polishing pad), and the polishing slurry penetrates between the platen (polishing pad) and the object to be polished, so that one side of the object to be polished can be polished flat.

[0021] The polishing slurry supplied onto the rotating platen is delivered to the polishing head and can be discharged from a discharge groove disposed between the polishing section cover and the platen.

[0022] The chemical mechanical polishing apparatus may further include a conditioner disc disposed on the polishing pad, and a conditioner disc arm portion for fixing the conditioner disc.

[0023] The conditioner disc may be formed on a disk having a smaller diameter than the surface plate and may be connected to an arm portion of the conditioner disc disposed above the surface plate. The arm portion of the conditioner disc may have a rotating shaft (not shown), and the rotating direction of the rotating shaft of the arm portion may be opposite to the rotating direction of the rotating shaft of the surface plate.

[0024] In one embodiment, when such a conditioner disk is provided, the conditioner disk can grind (dress) the surface of the polishing pad, thereby suppressing clogging of the polishing pad that may occur due to abrasive grains of the polishing slurry entering the pores of the polishing pad, and maintaining the polishing performance.

[0025] One or more of the above components has a surface treatment layer formed using a fluoropolyether group-containing compound.

[0026] Such components preferably include one or more selected from a surface plate, a polishing head, and a polishing slurry supply unit, more preferably include one or more selected from a surface plate, a rotating shaft of the surface plate, a polishing head, an arm part of the polishing head, a polishing slurry supply unit, an arm part of the polishing slurry supply unit, a polishing unit cover, an exhaust groove, and an arm part of a conditioner disk, but are not limited thereto. In one embodiment, such components preferably do not include a polishing pad and a conditioner disk.

At this time, the polishing slurry supply unit 9 drops the polishing slurry onto the polishing pad 5 and starts to oscillate. This oscillation is a semicircular arc between the approximate center and the outer periphery of the platen 6a. When the polishing slurry is uniformly dropped onto the polishing pad 5 of the platen 6a and covers the entire surface of the polishing pad 5, the polishing head 3 to which the polished object 2 is fixed rotates and presses the surface of the polished object 2 against the polishing pad 5. At this time, the surface of the polished object 2 adsorbed to the polishing head 3 can oscillate in a direction horizontal to the upper surface of the polishing pad 5 and can be polished flat.
