  • Patent number: 9620392
    Abstract: An apparatus for drying a substrate may include a spin chuck, a drying chamber and a drying fluid line. The spin chuck may be configured to support the substrate. The spin chuck may rotate the substrate. The drying chamber may be configured to receive the spin chuck. The drying chamber may have an inlet, an outlet and a vortex exhaust. A drying fluid may be supplied through the inlet into the drying chamber. The drying fluid may be drained through the outlet. A vortex of the drying fluid may be drained through the vortex exhaust. The drying fluid line may be connected to the inlet.

  • Patent number: 8882563
    Abstract: The invention relates to a chemical mechanical polishing system, comprising: at least one polishing platens rotatably installed with a platen pad mounted on its upper surface; a guide rail disposed along a predetermined path; a substrate carrier unit including a rotary union to downwardly press a substrate during a polishing process, the substrate carrier unit moving along the guide rail with loading the substrate; and a docking unit installed to be docked to the substrate carrier unit so as to supply air pressure to the rotary union which downwardly presses the substrate held by the substrate carrier unit, when the substrate carrier unit is positioned over the polishing platen, whereby even though the substrate carrier unit is moved to consecutively polish the substrate on the plural polishing platens, it substantially removes a phenomenon of the twisting of air pressure supply tubes due to the movement of the substrate carrier unit.

  • Patent number: 8662956
    Abstract: Provided are a conditioner of a chemical mechanical polishing apparatus for polishing a substrate over a platen pad that rotates and a method thereof. The conditioner includes a disk holder, a piston rod, a housing, and a load sensor. The disk holder secures a conditioning disk that finely cuts a surface of the platen pad. The piston rod delivers a normal force to the disk holder. The housing covers at least a portion of the piston rod. The load sensor is installed to receive the normal force that the piston rod delivers to the piston rod and measuring the normal force.

  • Patent number: 8597081
    Abstract: A pad conditioning disk, a pre-conditioning unit, and a CMP apparatus having the same are provided. The pad conditioning disk includes a base in which mountain-type tips and valley-type grooves are repeatedly connected to each other, and a cutting layer formed on the base layer. The cutting layer including conditioning particles deposited on surfaces of the tips and grooves. A surfaces roughness of conditioning particles deposited on the surfaces of the tips is less than a surface roughness of conditioning particles deposited on the surfaces of the grooves.
