Biswamohan Pani was also sentenced Wednesday in Boston to two years of probation and fined $17,500. He pleaded guilty in April to five counts of wire fraud.
Prosecutors say the 36-year-old Pani downloaded secret documents from Intel in May 2008, shortly after he announced he was leaving his Hudson, Mass., job.
Santa Clara, Calif.-based Intel valued those documents at between $200 million and $400 million. The company detected and reported the theft.
Intel rival Advanced Micro Devices Inc. hired Pani and cooperated with investigators. The Sunnyvale, Calif., company didn’t know of Pani’s scheme.
