Patent number: 11391756Abstract: As a semiconductor device is miniaturized, a scribe area on a wafer also tends to decrease. Accordingly, it is necessary to reduce the size of a TEG arranged in the scribe area, and efficiently arrange an electrode pad for probe contact. Therefore, it is necessary to associate probes and the efficient layout of the electrode pad. The purpose of the present invention is to provide a technique for associating probes and the layout of an electrode pad of a TEG to facilitate the evaluation of electrical characteristics. According to the present invention, the above described problem can be solved by arranging a plurality of probes in a fan shape or manufacturing the probes with micro electro mechanical systems (MEMS) technology.Type: GrantFiled: February 6, 2018Date of Patent: July 19, 2022Assignee: Hitachi High-Tech CorporationInventors: Ryo Hirano, Takayuki Mizuno, Tomohisa Ohtaki, Toru Fujimura, Shigehiko Kato, Yasuhiko Nara, Katsuo Ohki, Akira Kageyama, Masaaki Komori

Publication number: 20110291692Abstract: Provided is an apparatus for automatically detecting a failure position on a specified wiring line. The apparatus and a method for automatically detecting the failure position even on a long wiring line by applying a probe and an electron beam onto a sample and using an image of the current absorbed by the sample are provided.
