Patent number: 7357846Abstract: In a resist-removing process system 1 for removing a resist film formed on a wafer W, the resist film is denatured so as to make the resist film soluble in water and, then, the resist film is removed from the wafer by applying a water-wash processing to the denatured resist film. A series of the denaturing processing and the water-wash processing are carried out such that the denaturing processing of the resist film, which requires a long processing time, is performed by alternately using batch type resist-denaturing process units 21a and 21b each permitting a plurality of wafers W to be processed simultaneously, and the water-wash processing requiring a processing time shorter than that of the denaturing processing of the resist film is carried out by simultaneously operating six water-wash process units 22a to 22f each applying a water-wash processing to the wafers W one by one.Type: GrantFiled: July 27, 2004Date of Patent: April 15, 2008Assignee: Tokyo Electron LimitedInventor: Sadayuki Fujishima

Publication number: 20070281448Abstract: Methods of filling a gap on a substrate with silicon oxide are described. The methods may include the steps of introducing an organo-silicon precursor and an oxygen precursor to a deposition chamber, reacting the precursors to form a first silicon oxide layer in the gap on the substrate, and etching the first silicon oxide layer to reduce the carbon content in the layer. The methods may also include forming a second silicon oxide layer on the first layer, and etching the second layer to reduce the carbon content in the second layer. The silicon oxide layers are annealed after the gap is filled.Type: ApplicationFiled: May 25, 2007Publication date: December 6, 2007Applicant: Applied Materials, Inc.Inventors: Xiaolin Chen, Srinivas D.

Patent number: 7285916Abstract: A multi-chamber plasma process system includes a plurality of process chambers, each of which has an inductively coupled plasma generator. The inductively coupled plasma generator is electrically connected to a main power supply through a first impedance matcher. The first impedance matcher has at least one variable inductor. Ignition electrodes of the inductively coupled plasma generators are connected in parallel with an ignition power supply configured as a variable transformer. The variable inductor of the first impedance matcher and the variable transformer of the ignition power supply are controlled by a controller. Each process chamber has a plasma density regulator. Power supply systems, including an ignition power source, a radio frequency (RF) power source, an impedance matcher, etc. can be effectively integrated. As a result, it is possible to decrease the area of facilities and the cost of the system, and to individually control the plasma density of each process chamber.Type: GrantFiled: July 29, 2005Date of Patent: October 23, 2007Assignee: New Power Plasma Co., Ltd.Inventor: Soon-Im Wi
