Patent number: 7815366Abstract: In the present invention, a heating plate is divided into a plurality of regions. Integrated values of temperature fluctuations in each of the regions when a substrate is mounted on the heating plate in a normal state without extraneous matter are collected. A Mahalanobis reference space in the discriminant analysis method is formed based on the integrated values at normal time. During actual heat processing, an integrated value of temperature fluctuation of each of the regions when the substrate is mounted on the heating plate is then detected, so that a Mahalanobis distance about the integrated value during the processing is calculated based on the integrated value during the processing and the Mahalanobis reference space obtained in advance. Whether or not there is extraneous matter on the heating plate is determined by comparing the calculated Mahalanobis distance to a predetermined threshold value.Type: GrantFiled: November 8, 2005Date of Patent: October 19, 2010Assignee: Tokyo Electron LimitedInventors: Kouji Okamura, Hiroshi Tomita, Shuji Iwanaga, Shinichiro Araki

Patent number: 7780344Abstract: The estimation method of the invention for estimating the deteriorations of a magneto-resistive effect device by heat shocks involves applying heat shocks by laser irradiation to a structure including a thin-film magnetic head comprising a magneto-resistive effect device to propagate them to the magneto-resistive effect device, thereby causing the deteriorations of the magneto-resistive effect device. Thus, (1) the deterioration mode phenomenon of “local overheating plus vibration” can be imitated in a simple yet very approximate state so that a device likely to undergo characteristics deteriorations due to the thermal asperity problem can be detected early at an initial fabrication process stage, and (2) what specifications a head device structure less likely to offer the thermal asperity problem is in can be judged at a product development stage.Type: GrantFiled: September 25, 2007Date of Patent: August 24, 2010Assignee: TDK CorporationInventors: Takumi Yanagisawa, Naoki Ohta, Yosuke Antoku

Patent number: 7654734Abstract: A method for evaluating the thermal exposure of a selected metal component which has been exposed to changing temperature conditions is described. The voltage distribution on a surface of the metal component, or on a metallic layer which lies over the component, is first obtained. The voltage distribution usually results from a compositional change in the metal component. The voltage distribution is then compared to a thermal exposure-voltage model which expresses voltage distribution as a function of exposure time and exposure temperature for a reference standard corresponding to the metal component. In this manner, the thermal exposure of the selected component can be obtained. A related device for evaluating the thermal exposure of a selected metal component is also described.Type: GrantFiled: May 10, 2005Date of Patent: February 2, 2010Assignee: General Electric CompanyInventors: Liang Jiang, Lawrence Bernard Kool, Melvin Robert Jackson, Canan Uslu Hardwicke, Ji-Cheng Zhao, Ann Melinda Ritter, Ching-Pang Lee
