Patent number: 11060990Abstract: A semiconductor measurement device includes an electrode provided in a semiconductor sample, and a probe contactable with the semiconductor sample. A driver moves a contact position of the probe with respect to the semiconductor sample. A power supply applies electric power between the probe and the electrode. A measurement operation portion measures a current flowing via the semiconductor sample between the probe and the electrode as a voltage applied between the probe and the electrode is changed, the measurement operation portion measuring the current flowing for each of plural measurement points of a surface of the semiconductor sample while causing the probe to scan the measurement points, or while sequentially bringing the probe into contact with the measurement points. A display displays a relationship between the voltage and the current measured at each of the measurement points.Type: GrantFiled: August 27, 2018Date of Patent: July 13, 2021Assignee: TOSHIBA MEMORY CORPORATIONInventors: Jun Hirota, Tsukasa Nakai, Masako Kobayashi, Kazunori Harada
