Patent number: 8080126Abstract: In the plasma processing apparatus of the present invention, a first electrode for connecting a high frequency electric power source in a chamber is arranged to be opposed to a second electrode. A substrate (W) to be processed is placed between the electrodes. There is provided a harmonic absorbing member for being able to absorb harmonics of the high frequency electric power source so as to come in contact with a peripheral portion or circumference of a face of the first electrode 21, which is opposite the second electrode. The harmonic absorbing member absorbs the reflected harmonic before the harmonic returns to the high frequency electric power source. By absorbing the harmonic in this manner, the standing wave due to the harmonic will be effectively prevented from being generated, and the density of plasma is made even.Type: GrantFiled: August 21, 2008Date of Patent: December 20, 2011Assignee: Tokyo Electron LimitedInventors: Akira Koshiishi, Keizo Hirose

Patent number: 7364626Abstract: Substrate cleaning apparatus and method capable of preventing adhesion of particles to a substrate irrespective of being hydrophilic or hydrophobic are provided. Although a cleaning liquid ejected from a two-fluid nozzle 36 rebounds from a cup CP and scatters in the form of mist toward the center side of a wafer W, a rinsing liquid is supplied from a rinse nozzle 35 to form a water film 51 on the wafer W. Owing to the presence of the water film 51, the surface of the wafer W is protected from adhesion of particles contained in the mist. It is possible to prevent the particles in the mist from adhering to the wafer W and also possible to prevent a bad influence on the wafer W.Type: GrantFiled: November 1, 2002Date of Patent: April 29, 2008Assignee: Tokyo Electron LimitedInventors: Keizo Hirose, Kenji Sekiguchi

Patent number: 7010826Abstract: A substrate cleaning tool having little particle sticking to the tool and a substrate cleaning apparatus having the substrate cleaning tool are provided. The substrate cleaning tool 23 has a plurality of thready brush members 46 in a bundle. The brush members 46 are capable of passing cleaning liquid through and ejecting the cleaning liquid through respective surfaces of the members 46. In operation, the substrate cleaning tool 23 is brought into contact with a substrate W in their relative movement in order to clean the substrate W. As the cleaning liquid is ejected from the surfaces of the brash members 46, particles are washed away from the surfaces of the brash members 46. Consequently, it is possible to eliminate a possibility that the particles etc. are transferred to the substrate W.Type: GrantFiled: September 24, 2001Date of Patent: March 14, 2006Assignee: Tokyo Electron LimitedInventors: Keizo Hirose, Kenji Sekiguchi

Patent number: 6554010Abstract: In a cleaning apparatus for substrates, such as semiconductor wafers, a permeable core member 68 made of a synthetic resin is supplied with distilled water from a distilled water supply path 60 within a head portion 66 of a cleaning tool 24. A planar portion 72 is provided on the lower surface of the core member 68 and a porous resin sheet 69 is attached to the outer surface of the core member 68, to cover it. The cleaning tool 24 is provided with an air bearing cylinder 30 that imparts a vertical driving force to a rod 31 that presses against the surface of a wafer W which is being rotated, and the distilled water supply path 60 is provided within the rod 31. The distilled water supplied from the distilled water supply path 60 permeates through the core member 68 and the porous resin sheet 69 and is sent out of the head 66 so that a flowing film of distilled water is formed on the surface of the wafer W. Thus contamination and damage of the substrate is prevented and the shape of the head is not destroyed.Type: GrantFiled: July 26, 2000Date of Patent: April 29, 2003Assignee: Tokyo Electron LimitedInventors: Keizo Hirose, Kenji Sekiguchi, Tomohide Inoue, Takanori Miyazaki, Kinya Ueno

Patent number: 6544380Abstract: An apparatus for treating a substrate which includes a chamber and an opening formed in the chamber allowing the substrate to be conveyed into the chamber or taken out thereof. The chamber, also, includes a detachable baffle plate that fits around an electrode. For treatment to commence, the substrate is placed on the electrode and the chamber is exhausted of or supplied with gases. The electrode is then vertically lifted together with the baffle plate and the baffle plate is moved either to a position that is higher in level than an upper end of the opening of the chamber or to a position that is lower in level than a lower end of the opening of the chamber. This allows the baffle plate to shield a region near the opening of the chamber from a treatment region and allows reaction products to be adhered to the baffle plate.Type: GrantFiled: February 19, 2002Date of Patent: April 8, 2003Assignee: Tokyo Electron LimitedInventors: Masayuki Tomoyasu, Akira Koshiishi, Kosuke Imafuku, Shosuke Endo, Kazuhiro Tahara, Yukio Naito, Kazuya Nagaseki, Keizo Hirose, Mitsuaki Komino, Hiroto Takenaka, Hiroshi Nishikawa, Yoshio Sakamoto
