A solvent remover communicable with the coating chamber is included to remove excess solvent that does not get transformed into the solvent vapor to prevent the excess solvent from dropping on the substrate.Type: GrantFiled: December 29, 2003Date of Patent: February 5, 2008Assignee: ASML Holding N.V.Inventor: Andrew Nguyen

Patent number: 7323060Abstract: A forward direction-only path (first substrate transport path) is formed for transporting substrates in a forward direction to pass the substrates on to an exposing apparatus. A separate, substrate transport path (second substrate transport path) is formed exclusively for post-exposure bake (PEB). Substrate transport along each path is carried out independently of substrate transport along the other. A fourth main transport mechanism is interposed as a predetermined substrate transport mechanism between transfer points consisting of a buffer acting as a temporary storage module for temporarily storing the substrates and a post-exposure bake (PEB) unit corresponding to a predetermined treating unit. This arrangement forms the path for transporting the substrates between the buffer and the PEB unit, to allow PEB treatment of the substrates to be performed smoothly. Similarly, the substrates are transported smoothly to the buffer.Type: GrantFiled: December 10, 2004Date of Patent: January 29, 2008Assignee: Dainippon Screen Mfg. Co., Ltd.Inventors: Yoshihisa Yamada, Masafumi Maeda, Takashi Taguchi

Patent number: 7311781Abstract: An apparatus causes a substrate to rotate and supplies a treatment liquid to a substrate surface to make a treatment, without concern that a mixed substance is eluted from a cup in the use for a long time, or a thin film comes off from an inside wall surface to be contamination-causing substances even if the cup made of a water-repellent material for collecting a treatment liquid becomes hydrophilic. A cup 16 disposed to surround the sides and underside of a substrate W rotating while being held by a spin chuck 10, and serving to collect a treatment liquid diffused from the substrate to the surroundings, is made of a plastic material. Further, an inside wall surface of an upper-side cup part 24 of the cup 16, being a portion on which the treatment liquid having been diffused from the substrate impinges, is roughened to be a hydrophilic surface.Type: GrantFiled: October 25, 2005Date of Patent: December 25, 2007Assignee: Dainippon Screen MGF, Co., LtdInventors: Kentaro Tokuri, Kenya Morinishi, Masaki Iwami

Patent number: 7288154Abstract: There is provided an apparatus for optical disc spin-coating, comprising a cap having a tapered protruding portion or a recess in its central lower portion; a turntable for rotation that has a tapered recess or protruding portion formed in an end of its central axis that is inserted into a center hole of an optical disc, wherein the tapered recess or protruding portion of the turntable is coupled with the tapered protruding portion or recess of the cap in a convexo-concave structure; and a vacuum hole formed in an optical disc support of the turntable. When the cap is eccentrically placed on the optical disc, the cap can be easily attached. In addition, the cap can be easily detached from the optical disc by using vacuum pressure. As a result, the operability and manufacturing efficiency can be increased.Type: GrantFiled: June 17, 2005Date of Patent: October 30, 2007Assignee: LG Chem.

Publication number: 20070231483Abstract: A liquid processing apparatus is arranged to planarize a film on a substrate by supplying onto the film a process liquid for dissolving the film while rotating the substrate. The apparatus includes a substrate holding member configured to rotatably hold the substrate in a horizontal state, a rotation mechanism configured to rotate the substrate holding member, and a liquid supply mechanism configured to supply the process liquid onto a surface of the substrate. The liquid supply mechanism includes first and second liquid delivery nozzles configured to deliver the same process liquid. The first liquid delivery nozzle has a smaller diameter and provides a smaller delivery flow rate, as compared to the second liquid delivery nozzle. The first liquid delivery nozzle is inclined to deliver the process liquid in a rotational direction of the substrate, and is movable between a center of the substrate and a peripheral edge thereof.Type: ApplicationFiled: March 27, 2007Publication date: October 4, 2007Inventors: Hiromitsu Nanba, Masahiro Yoshida, Yuji Murakami, Hiroshi Nagayasu
