Remembering Jack Kilby

Jack Kilby, the man who created revolution in microelectronics passed away on June 20 in Dallas, Texas. Kilby filed for a patent for the invention of monolithic IC in February 1959. I got to know about this man and his inventions when he was awarded Nobel Prize in the year 2000. I also got to know that the monolithic IC invented by Kilby used Germanium and not the Silicon that is used in today's chips. The first IC that used Silicon was invented by Robert Noyce, who filed for a patent 5 months after Kilby filed the patent. Kilby also invented the Pocket Calculator.
