Patent number: 11841381Abstract: A wafer inspection method and inspection apparatus are provided. On a wafer having layout lines connecting electrode points of individual dies in series, the dies within a matrix range are inspected one after another in turn in a column/row control means by a first switch group and a second switch group of a probe card, so that each die is selectively configured in a test loop of a test process by turning on/off of a corresponding switch. Thus, after inspection of a die under inspection (a selected die) within the matrix range is complete, the column/row control means is used to switch to a next die to achieve fast switching. Accordingly, for the inspection procedure of each die within the matrix region, a conventional procedure of moving one after another in turn can be eliminated, significantly reducing the total test time needed and enhancing inspection efficiency.Type: GrantFiled: September 22, 2022Date of Patent: December 12, 2023Assignee: CHROMA ATE INC.Inventors: Tsun-I Wang, I-Shih Tseng, Min-Hung Chang, Tzu-Tu Chao

Publication number: 20230105201Abstract: A wafer inspection method and inspection apparatus that perform a voltage inspection of a die on a wafer by a probe module. The probe module includes a processing module, a first probe coupled to a first electrode point of the die, and a second probe coupled to a second electrode point of the die. The first probe is coupled to the processing module, and the second probe is grounded. The processing module provides the die with a driving current through the first probe, and obtains an inspection voltage corresponding to the die. The processing module generates an inspection result of the inspection voltage based on two reference voltages respectively representing a high critical threshold value and a low critical threshold value of the die under a normal operation. The inspection result indicates an operating status of the die. Thus, inspection costs are reduced and inspection efficiency is enhanced.Type: ApplicationFiled: September 29, 2022Publication date: April 6, 2023Inventors: TSUN-I WANG, I-SHIH TSENG, MIN-HUNG CHANG, TZU-TU CHAO

Publication number: 20090161311Abstract: It's a type of top mount surface airflow heatsink, utilizing the upper ceiling wall separated by an air gap, working together with the upper surface of a heating device (microprocessor) producing an air current. It's a simple device, with a low cost using the Reynolds Equation Re=(?umd)/??2,500; with ? being the fluid density, um being the free-stream fluid velocity, d being the pipe distance or diameter, ? being the fluid viscosity. Since the airflow produces air turbulence, it causes the frequent heat exchanges in the air. It also causes the obvious temperature changes within the different layers of air. Therefore, it increases tremendously, the efficiency of dissipating the heat. It requires only the input of the air. The operation is simple and it allows the usage of even higher heat generating devices. Thus it promotes the alternative usage of this top mount heatsink device within the installation of circuit board components.Type: ApplicationFiled: November 1, 2007Publication date: June 25, 2009Applicant: Chroma Ate, IncInventor: I-Shih Tseng
