Patent number: 8225237Abstract: A method to determine a process window is disclosed. First, a pattern data is provided. Second, a bias set is determined. Then, a resizing procedure is performed on the pattern data in accordance with the bias set to obtain a usable final resized pattern to be a target pattern of changed area. The final resized pattern is consistent with a minimum spacing rule, a contact to poly rule and a contact to metal rule. Accordingly, the target pattern is output.Type: GrantFiled: November 27, 2008Date of Patent: July 17, 2012Assignee: United Microelectronics Corp.Inventors: Te-Hung Wu, Sheng-Yuan Huang, Cheng-Te Wang, Chia-Wei Huang, Ping-I Hsieh, Po-I Lee, Chuen Huei Yang, Pei-Ru Tsai

Patent number: 7913196Abstract: A method of verifying a layout pattern comprises separately steps of obtaining a simulated pattern at a lower portion of a film by using a layout pattern as a mask to transfer the layout pattern to the film, and obtaining a simulated pattern at an upper portion of the film by using the layout pattern as a mask to transfer the layout pattern to the film. The layout pattern is verified according to the upper and lower simulated patterns.Type: GrantFiled: May 23, 2007Date of Patent: March 22, 2011Assignee: United Microelectronics Corp.Inventors: Te-Hung Wu, Chia-Wei Huang, Chuen Huei Yang, Sheng-Yuan Huang, Pei-Ru Tsai, Chih-Hao Wu

Patent number: 7886254Abstract: A method for amending layout patterns is disclosed. First, a layout pattern after an optical proximity correction is provided, which is called an amended pattern. Later, a positive sizing procedure and a negative sizing procedure are respectively performed on the amended pattern to respectively obtain a positive sizing pattern and a negative sizing pattern. Then, the positive sizing pattern and the negative sizing pattern are respectively verified to know whether they are useable. Afterwards, the useable positive sizing pattern and the negative sizing pattern are output for the manufacture of a reticle when they are verified to be useable.Type: GrantFiled: May 27, 2008Date of Patent: February 8, 2011Assignee: United Microelectronics Corp.Inventors: Chia-Wei Huang, Te-Hung Wu, Pei-Ru Tsai, Ping-I Hsieh

Patent number: 7669153Abstract: A method for correcting a photomask pattern is provided. The correcting method performs a verification of a focus-exposure matrix (FEM) and an overlay variation on a layout area having contact holes or vias in a layout pattern so as to generate a hint information. The layout pattern of the photomask is corrected according to the hint information to prevent the contact holes or vias from being exposed in arrangement to corresponding metal layer, poly layer, or diffusion layer.Type: GrantFiled: April 30, 2007Date of Patent: February 23, 2010Assignee: United Microelectronics Corp.Inventors: Te-Hung Wu, Chuen-Huei Yang, Sheng-Yuan Huang, Chia-Wei Huang, Pei-Ru Tsai

Patent number: 7496359Abstract: The present invention is to provide a system for enabling a user to know whereabouts of his or her missing mobile phone, which comprises a mobile phone and a remote controller. The mobile phone comprises a control module including a wireless transceiver unit for receiving a wireless search signal transmitted from the remote controller and adapted to convert the received wireless search signal into an instruction for controlling an output unit of the mobile phone consisting of a light emitting unit, a drive unit, an audio unit, and/or a display unit to generate corresponding light, vibration, sound, and/or display characters for alerting the user. The remote controller comprises a button which, when pressed by the user, causes the remote controller to generate the wireless search signal and transmit the same to the mobile phone for executing the corresponding instruction.Type: GrantFiled: January 10, 2006Date of Patent: February 24, 2009Assignee: Inventec CorporationInventor: Pei-Ru Tsai

Patent number: 7447009Abstract: A portable electronic device including a first body, a second body, and at least one speaker is provided. The second body is pivotally connected to one side edge of the first body, such that the second body is selectively rotated to cover the first body, or to form an angle with respect to the first body. The speaker is movably disposed on an upper surface of the first body, and can be moved relative to the first body. Thus, the speaker can be moved and fixed to a predetermined position to achieve optimized output sound quality.Type: GrantFiled: January 30, 2007Date of Patent: November 4, 2008Assignee: Inventec CorporationInventors: Shih-Hsuan Wang, Pei-Ru Tsai
