Background
In April 2010. Piotech was founded by a group of returning international technology veterans from the United States along with the Chinese Academy of Sciences.

In 2015, Piotech announced that it had received a 270 billion yuan investment from a group that included the China Integrated Circuit Industry Investment Fund and Advanced Micro-Fabrication Equipment.
