Patent number: 6652707Abstract: Demounting workpieces attached to an adhesive surface of an adhesive film with a workpiece demounting apparatus having a base and a plurality of substantially parallel blades mounted to the base. Each of the blades has a substantially linear blade edge, each blade edge lying within a blade-edge plane that is substantially perpendicular to the blades. The spacing between the blades is small enough to support said workpieces and large enough to permit the adhesive film to pass between the blades after being cut by said blade edges during a workpiece demounting operation. The plurality of blade edges thus provides a substantially planar blade-edge surface, in the blade-edge plane, for cutting the adhesive film and for supporting the workpieces while the adhesive film is pulled free from said workpieces.Type: GrantFiled: April 29, 2002Date of Patent: November 25, 2003Assignee: Applied Optoelectronics, Inc.Inventors: Brian Ishaug, Chung-Yung Wang, Hung-Lun Chang

Patent number: 6586146Abstract: A method of figuring an exposure energy. A required exposure energy is calculated according to a critical dimension (CD) of an exposing layer. A first CD deviation is obtained from a layer before the exposing layer. From the first CD deviation, a first energy compensation is calculated. Whether the deviation of photoresist sensitivity of two sequential batches is less than 1% is checked. If the deviation of photoresist sensitivity of two sequential batches is less than 1%, a sum of the required exposure energy and the first energy compensation is the exposure energy applied to the exposing layer. Otherwise, a second CD deviation is commutated according to the deviation of photoresist sensitivity of two sequential batches. A second energy compensation is then obtained from the second CD deviation, and a sum of the required exposure energy and the first/second energy compensation is the exposure energy applied to the exposing layer.Type: GrantFiled: August 31, 2001Date of Patent: July 1, 2003Assignee: United MicroelectronicsInventors: Kun-Yuan Chang, Wang-Hsiang Ho, Yu-Ping Huang, Li-Dar Tsai, Chung-Yung Wu

Publication number: 20020101428Abstract: The invention provides a graphic engine and a method that reduces the idle time of the graphic engine by validity test. The validity test is performed when the back buffer is full and the graphic engine continues to write a primitive into a front buffer. The validity test compares the maximum Y-coordinate of the primitive with the Y-coordinate of the current scan line. If the maximum Y-coordinate of the primitive is less than the Y-coordinate of the current scan line, the graphic engine keeps on executing the primitive processing procedure. On the other hand, if the maximum Y-coordinate of the primitive is greater than or equal to the Y-coordinate of the current scan line, the graphic engine halts the primitive processing procedure until the maximum Y-coordinate of the primitive is less than the Y-coordinate of the current scan line.Type: ApplicationFiled: January 28, 2002Publication date: August 1, 2002Applicant: Silicon Integrated Systems Corp.Inventors: Chien-chung Hsiao, Kwo-woei Yet, Chung-yung Lee
