Final answer:
The 'traitorous eight' left Shockley Semiconductor to establish Fairchild Semiconductor, which played a critical role in developing the integrated circuit.
Step-by-step explanation:
The company founded by the 'traitorous eight' who left Shockley Semiconductor was Fairchild Semiconductor.
In 1957, eight key employees of Shockley Semiconductor, dissatisfied with management, departed to establish their venture. This group, famously known as 'the traitorous eight,' included notable figures such as Robert Noyce and Gordon Moore, who would later contribute significantly to the advancement of the electronics industry.
In 1958, shortly after founding Fairchild Semiconductor, Robert Noyce, alongside Jack Kilby at Texas Instruments, independently invented the integrated circuit, a vital development that enabled the miniaturization and improved functionality of electronic devices, propelling the electronics revolution forward.
