踊り場を迎えたトランジスタ技術

抄録

The transistor technology is one of the fundamental technologies that support the information society. The transistor has been developed according to Moore's law over the past several decades. The transistor technology has been confronted with limitation of technology in many times, but engineers have overcome these limitations by developing various technical methods.

"Physical limit" is approaching that the transistor's line width becomes the level of atomic size. Transistor technology is stepping into areas where Moore's law cannot be applied. Several technical methods have also been proposed to overcome the physical limit. This paper outlines the history of transistor technology, and also introduces the direction of current technology.
