Publication number: 20090212794Abstract: A test key for a semiconductor structure is provided for in-line defecting defects of the contact. The test key is disposed on a scribe line of a wafer substrate, and includes conductive structures and contacts under test. The conductive structures are electrically connected with the substrate and the contacts under test are not electrically connected with the substrate. The conductive structures and the contacts under test are regularly arranged in array. When an electronic beam is utilized to perform in-line monitoring, the normal contacts under test will be shown as bright dots and the bright dots are regularly arranged in the array; any contact under test with defect will be shown as a dark dot which results in an irregular arrangement of the bright dots.Type: ApplicationFiled: August 12, 2008Publication date: August 27, 2009Applicant: PROMOS TECHNOLOGIES INC.Inventors: Chung-I Chang, Hui-An Chang, Neng-Cheng Wang

Publication number: 20060098217Abstract: The present invention is suitable for a computer to (printing) plate to generate specific color accurately, applied data conversion modules included in Profile technique to generate specific color. Drafting software is developed for the pre-print designers adjust CMYK four colors process for printing in allowable proportion to meet the customer's color specification. A tour guide test table composed of 600 colorants is printed out by CMYK color printer, and a subsequent test table constructed by moving colorimeter or spectrophotometer through the colorants, first a forward module constructed by converting CMYK into CIEL*a*b*, and then a reverse module converting CIEL*a*b* into CMYK constructed by optimizing solutions of delta error convergence and error estimates methods. After measuring the CIEL*a*b* values of the specific color by colorimeter, applied the forward and reverse modules to predict CMYK color values in allowable proportion, achieve a better, speedy, and accurate drafting effects.Type: ApplicationFiled: January 19, 2005Publication date: May 11, 2006Inventors: Chung-I Chang, Shih-Chang Chang, Chia-Pin Chueh

Patent number: 6318196Abstract: The present invention relates to an improved structure of an automobile center lock driving apparatus, and in particular to an center lock driving apparatus having an inertia gear module. The driving apparatus comprises a driving pull-rod, a transmission gear, an inertia clutching gear, an active gear and a motor. The apparatus provides a solution to wear of the gears, dislocation of the gears, and “dead lock” of the driving pull-rod, and gear damages as a result of shock caused by dislocation of transmission gear modules. At instantaneous driving, the driving pull-rod can be driven more smoothly and stable as a result of the inertia gap between the gear modules.Type: GrantFiled: November 1, 1999Date of Patent: November 20, 2001Inventor: Chung-I Chang
