Answer: Semiconductor Equipment

In the fictional alternate-timeline universe of the Terminator franchise, Cyberdyne Systems was a small manufacturing company founded in 1984 that specialized in processors and other computer related equipment. After a T-800 (Model 101) Terminator unit, sent from the future, was damaged in their factory, the company reverse engineered the salvaged components of the Terminator’s remains. Using that technology, they created powerful microprocessors for weapons systems and, as a result, became a major contractor for the U.S. military. One thing led to another and they ended up developing Skynet, which was the start of the massive war that resulted in the Terminators being sent back in the first place. The Cyberdyne Systems headquarters made an appearance in the film Terminator 2 as seen in the movie still here.

In real life, that building still exists in Fremont, California and is occupied by Mattson Technology. The company was founded in 1988 and specializes in semiconductor wafer processing equipment used in the fabrication of integrated circuits. Equipment, we’re sure, that is not at all based on technology scavenged from assassin robots sent from the future to alter the timeline and that it is purely, totally, and completely coincidental that the building is occupied by a company involved in the semiconductor industry. But seriously, we have nothing to worry about. Skynet went online in August of 1997 and here we are, two decades on with no global collapse or killer robots. Everything’s fine. Probably.
