Newly employed by Texas Instruments, Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958.[10] In his patent application of 6 February 1959,[11] Kilby described his new device as “a body of semiconductor material … wherein all the components of the electronic circuit are completely integrated.”[12] The first customer for the new invention was the US Air Force.[13]
Kilby won the 2000 Nobel Prize in Physics for his part of the invention of the integrated circuit.[14] Kilby's work was named an IEEE Milestone in 2009.[15]
