Japanese English Share Tweet Google+ Skip The ever-accelerating evolution of semiconductors The key inventions that laid the foundation of today's information technology (IT) had already emerged by the end of the 19th century, including the light bulb by Thomas Alva Edison, telephone and telegraph by Alexander Graham Bell, wireless telegraphy by Guglielmo Marconi, and cathode ray tube by Karl Ferdinand Braun. These basic technologies have made remarkable progress since then, due in large part to the development of semiconductors. Let us trace the evolution of the semiconductor through the history of epoch-making discoveries and inventions, starting with the birth of the vacuum tube—a distant ancestor of semiconductor devices. 1904 1946 1948 1955 1957 1959 1965 1971 1977 1980 1983 1991 1993 1995 2002 2004 2007 2010 2011 2013 2015 2016 GRAPH Share Tweet Google+ PRESENTED BY TOKYO ELECTRON Terms of Use (for the website) Privacy Policy Sitemap Concept ©2011-2021 Tokyo Electron Limited.
