Toshitsugu Sakamoto

About

Toshitsugu Sakamoto is a leading figure in the development of advanced nonvolatile programmable logic devices, with a particular focus on NanoBridge technology and robust Cu atom switches. His research centers on creating novel resistive-change switches that can withstand extreme environments, making them ideal for high-temperature applications such as aerospace and industrial electronics. Sakamoto’s major contributions include the demonstration of a NanoBridge-based field-programmable gate array (FPGA) that operates reliably in high-temperature environments, featuring a high on/off conductance ratio and weak temperature dependence. He also developed a robust Cu atom switch with an over-400°C thermally tolerant polymer-solid electrolyte (TT-PSE), which selectively eliminates weak hydrocarbon bindings to enhance thermal stability. These innovations have garnered attention in the field, with his most-cited papers accumulating 9 and 6 citations, respectively. Sakamoto’s work is notable for pushing the boundaries of standard Cu-BEOL compatibility, enabling nonvolatile programmable logic that remains functional under extreme thermal stress. His achievements represent a significant step toward more resilient and versatile electronic systems for demanding applications.
