Business Fields and Main Products

Semiconductor and Component Test System

ATE Business

Semiconductors are a core electronic component used in a variety of devices, such as smartphones, personal computers, household electrical appliances, and motor vehicles, which are indispensable to the lives of people. The types of semiconductors are broad from logic ICs and analog ICs to memory ICs. Each type of semiconductor has its own unique functionality and circuitry with performance rapidly advancing each day.

Automated Testing Equipment (ATE) verify the quality, performance and reliability of semiconductors by electrically testing these complex and multifarious functions of semiconductors with high accuracy. The automated testing technologies from Advantest at the top of the industry are contributing to higher efficiency in production on customer sites, technological innovations of the electronics industry, and greater safety, security and comfort for society.
