Semico Research publishes 2015 semiconductor companies Capex ranking. "In the top fifteen, the company with the largest increase is Sony, with a 207% increase to almost US$2 billion. The bulk of this increase is to expand image sensor production capacity, but some will also be spent on camera module production capacity, a relatively new market for Sony. Sony’s dollar increase is second only to Samsung’s, but this is partly due to the decline in value of the yen."
The ranking has been published on June 22, a week before the latest Sony announcement of the additional investment.
