Japan Electronic Materials Corporation (JEM) was established in 1960 to manufacture cathode heaters for CRTs as its core products, and the corporation has been a pioneer in leading the industry including today's venture companies. In 1965, JEM developed the world's first fluorescent electron tube made of tungsten to display characters, and further developed a probe card for testing semiconductor wafers and started production of probe cards. Since then, JEM has expanded its business sites throughout Japan, America, Europe, and the Pacific Rim. JEM is deeply involved in the global electronic market, specifically in the field of semiconductors. With a diversified product line and the ability to deliver high-quality products, JEM became an industry leader in the worldwide probe card market. In August 1998, JEM became a publicly traded company in Japan and is listed on JASDAQ.
