WebLe 10 mai 1954, Texas Instruments sort le premier transistor au silicium 8 . Pour la grande majorité des applications, on utilise le silicium alors que les matériaux plus exotiques tels que l'arséniure de gallium et le nitrure de gallium sont plutôt utilisés pour réaliser les transistors hyperfréquences . WebThe BJT was invented in 1947 by john Bardeen and Walter Brattain and in 1951 William Shockley made modern version of the transistor BJT. This invention completely revolutionized in electronic industry and transistor much wide spread application in computer chips, communication satellite, calculator etc.
