Towards a prosperous future

JSW AFTY is working towards bringing the technological resources and latent capabilities we have developed and accumulated up until now to fruition. We are also focusing on improvements in these resources and the development of new technologies, to bring about a prosperous future for our customers, us, and society through these efforts.

Company History

Since AFTY Corporation, the predecessor of our company, it continued to develop on the base of ECR plasma deposition technology as the NTT Group company.
From September 2007, it started operation as a member of Mitsui Engineering and Shipbuilding (MES) Group, and the semiconductor and flat panel manufacturing equipment businesses of the MES Group that they had developed for each of their own products were incorporated into our businesses.
On April 2014, we make a new start as a member of the Japan Steel Works Group. It strengthens consistent services from development to manufacture, sales, and after-sales service, and we contribute to the creation of greater value for our customers.
