Report for 2017

The CSR Report 2017 has been published to verify CSR activities in fiscal 2016 and promote communication with stakeholders. The report discloses information on efforts we consider particularly important among our various initiatives. This year, we include three special features to give readers a better understanding of TOK’s core technology of semiconductor microprocessing, and the related products of high purity chemicals. In addition, we have added as many Voice columns as possible to introduce the thoughts of people who are active at the forefront of our various activities.
