Patent number: 8527314Abstract: A user terminal is connected through the Internet to a server. On the basis of the identification information of the client inputted from the client terminal, the server extracts an service selected by the client from a database for user management, further, extracts calculated maintenance contents for each service from a database for service management and sends them to the user terminal. Thus, the user can collect maintenance contents, such as the staff capable of providing service, the time until the user receives a service, and the charge, so that the user can utilize the information as indications to select an optimal service such as maintenance.Type: GrantFiled: July 14, 2004Date of Patent: September 3, 2013Assignee: Tokyo Electron LimitedInventors: Hiroshi Nishikawa, Youichi Araki, Kiichi Hama

Patent number: 8032629Abstract: A computer terminal connected to a manufacturing apparatus as an object of the maintenance management is connected to a server machine providing a maintenance management service by a network, enabling bi-directional communication. The computer terminal monitors whether or not the object apparatus is restarted and transmits restart information indicating restart completion due to maintenance performed on the object apparatus by the customer to the server machine upon determining that the object apparatus is restarted. The server machine generates a random number within the specific range when receiving the restart information from the computer terminal, retrieves points corresponding to the random number from the lottery point setting storage unit, and stores the retrieved points in the lottery point storage unit. This can encourage the customer to perform maintenance on the object apparatus in order to indicate said restart completion to obtain more points.Type: GrantFiled: February 18, 2010Date of Patent: October 4, 2011Assignee: Tokyo Electron LimitedInventors: Hiroshi Nishikawa, Youichi Araki, Kiichi Hama

Patent number: 7975049Abstract: A computer terminal connected to a manufacturing apparatus as an object of the maintenance management is connected to a server machine providing a maintenance management service by a network, enabling bi-directional communication. The computer terminal transmits maintenance information including a kind of a maintenance method executed at the customer side to the server machine. The server machine acquires the kind of the maintenance method from the maintenance information received from the computer terminal, retrieves points corresponding to the kind of the maintenance method, and stores the retrieved points in a maintenance point storage unit. More points are set for more time consuming maintenance. This can encourage the customer to perform more time consuming maintenance on the manufacturing apparatus in order to obtain more points.Type: GrantFiled: February 18, 2010Date of Patent: July 5, 2011Assignee: Tokyo Electron LimitedInventors: Hiroshi Nishikawa, Youichi Araki, Kiichi Hama

Publication number: 20100145780Abstract: A computer terminal 110 connected to a manufacturing apparatus 120 as an object of the maintenance management is connected to a server machine 210 providing a maintenance management service by a network 500, enabling bi-directional communication. The computer terminal transmits status information on an apparatus as an object of the maintenance management to the server machine in response to a status information transmission request received from a server at every predetermined interval. The server machine includes a status point information management database for storing status points generated according to status information and determines whether status information has been received at every predetermined interval. Each time it is determined that status information is received, a predetermined point is added so as to update the status points of the status point information management database. This can encourage a customer to perform maintenance by him/herself and reduce workload of a serviceman.Type: ApplicationFiled: February 18, 2010Publication date: June 10, 2010Applicant: TOKYO ELECTRON LIMITEDInventors: Hiroshi NISHIKAWA, Youichi Araki, Kiichi Hama

Patent number: 7109660Abstract: A plasma processing device is able to positively enhance a process-gas exhaust efficiency in a processing region and restrict plasma leaking. A processing container of a magnetron type parallel plate plasma processing device has a separator for separating the inside of the processing container into a processing region and an exhaust region. The separator has a plurality of gas passage holes to establish communication between the processing region and the exhaust region, and consists of a non-conductive member. A conductive member is disposed on a gas passage-side surface facing the gas passage holes. A voltage V is applied by a power supply to the conductive member so that the gas passage-side surface is at a potential higher than that of a processing-region surface.Type: GrantFiled: March 28, 2003Date of Patent: September 19, 2006Assignee: Tokyo Electron LimitedInventors: Hiroyuki Ishihara, Youichi Araki, Toshiki Takahashi, Takuya Kubo, Atsushi Ito, Yoko Ono
