Photonic Integration Based On A Ferroelectric Thin-Film Platform

By Advantest - 11 Jan, 2021 - Comments: 0

Photonic-integrated circuits (PICs) using ferroelectric materials are expected to be used in many applications because of its unique optical properties such as large electrooptic coefficients. In this study, a novel PIC based on a ferroelectric thin-film platform was designed and fabricated, where high-speed optical modulator, spot-size converters (SSCs), and a variable optical attenuator (VOA)... » read more

Accurate Error Bit Mode Analysis Of STT-MRAM Chip With A Novel Current Measurement Module

By Advantest - 11 Jun, 2019 - Comments: 0

Authors: (Advantest) Ryo Tamura, Ibuki Mori Naoyoshi Watanabe; (Tohoku University) Hiroki Koike, Tetsuo Endoh. A novel memory test system is needed for future STT-MRAM mass production that supports error bit analysis and its mode categorization on STT-MRAM chip measurement, as STTMRAM cell’s switching is a probabilistic phenomenon based on quantum mechanics. In order to meet this requireme... » read more
