According to foreign media reports, committed to diversifying the 3D NAND flash photoresist suppliers, Samsung Electronics has abandoned the plan due to the failure to find a supplier that meets the requirements.
From the Korean media reports, Samsung Electronics at least 4 potential suppliers with contact, all Japanese manufacturers, including the world’s largest photoresist supplier Tokyo should be chemical industry, but sources revealed that they have not met the requirements of Samsung Electronics.
In the report, the foreign media mentioned that Samsung Electronics has repeatedly contacted Japanese photoresist suppliers to find new suppliers, but they have not been able to meet the requirements in terms of thickness.
As a key material for the production of advanced 3D NAND flash memory, Samsung Electronics has been supplied by South Korea’s own Dongjin Shimeiken, in 2013 before they began producing 3D NAND flash memory, Samsung Electronics has worked with this company to develop photoresists.
Tokyo Chemical Industry and other manufacturers can not request, which means that Samsung Electronics in the future in the production of 3D NAND flash, will still use the photoresist of Dongjin Shimaken, has been the exclusive supply of nearly 10 years Dongjin Shimaken, the next period of time will remain the exclusive supplier.
