Worldwide semiconductor revenue totaled $343.5 billion in 2016, a 2.6 percent increase from 2015 revenue of $334.9 billion, according to final results by Gartner.

The research firm said tha the top 25 semiconductor vendors' combined revenue increased 10.5 percent, a significantly better performance than the overall industry's growth; however, most of this growth resulted from merger and acquisition (M&A) activity.

"The semiconductor industry rebounded in 2016, with a weak start to the year, characterized by inventory correction, giving way to strengthening demand and an improving pricing environment in the second half," said James Hines research director at Gartner. "Worldwide semiconductor revenue growth was supported by increasing production in many electronic equipment segments, improving NAND flash memory pricing and relatively benign currency movements."

Intel retained its No. 1 position as the largest semiconductor manufacturer and grew its semiconductor revenue 4.6 percent in 2016. Samsung Electronics continued to maintain the No. 2 spot with 11.7 percent market share.
