PSMC is now PDMC

Precision Semiconductor Mask Corporation (PSMC) was incorporated in Taiwan in 1997. I called on their maskshop in Hsinchu in the late 90's for DuPont Photomasks. In 2000, US-based Photronics acquired the majority share of PSMC, changed the name to Photronics Semiconductor Mask Corporation, and made the maskshop their foothold for expansion in Taiwan. In 2006 Photronics would build a second maskshop in Taichung focused on large area masks for flat panel displays that has proven to be a big success. As of this week, Japan-based Dai Nippon Printing (DNP) and Photronics have officially merged their PSMC and DPTT (DNP Photomask Technology Taiwan) assets in a joint venture. So PSMC changes names once again, this time to PDMC (Photronics DNP Mask Corporation), and becomes even stronger.
