The story
Aptina Imaging was created as a spin-off of Micron Technology's Image Sensor Division in March 2008. Aptina was still an independent division within Micron until July 2009, when Aptina became an independent, privately held company, being partially sold to a group including TPG and Riverwood Capital. ON Semiconductor Corporation completed the acquisition of Aptina Imaging in August 2014.
