Leading semiconductor test equipment supplier Advantest Corporation (TSE: 6857, NYSE: ATE) announced today that it has developed a technology utilizing short-pulse terahertz waves for analysis of electrical circuits. The technology has 2 major applications - analysis of the transmission characteristics (S parameters) of devices using the sub-terahertz band (100GHz~1THz), and characterization and location of failures in chip circuits (TDT/TDR). The new technology overcomes the technical obstacles and prohibitive cost of existing technologies, and will contribute significantly to the development and wider adoption of these leading-edge devices.
