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

Patent number: 11047550Abstract: The electronic device provided includes a housing with two first through holes and two second through holes, a light guiding structure, and a light source. A first section is provided between the two first through holes, and a second section is provided between the two second through holes. The length of the first section is less than the length of the second section. The light guiding structure includes a light guiding layer, a diffusion layer, and a light adjusting layer. The light adjusting layer is disposed at the position of the first section. The light source is disposed at a position that corresponds to an intersection of the first section and the second section. Light emitted by the light source passes through the light transmitting portion and the intersection, and is separately emitted through the first through holes and the second through holes along the light transmitting portion.Type: GrantFiled: November 30, 2020Date of Patent: June 29, 2021Assignee: ASUSTEK COMPUTER INC.Inventors: Chun-Mao Tseng, Chien-Yi Huang, Chao-Shun Wang, Min-Che Kao, Min-Hung Chang, Lu-Chien Chen, Hui-Fang Yan, Yi-Nian Zou, Min-Yu Wu, Hao-Yen Chang, Li Ding, Chi Liu, Yu-Jen Chen
