Samsung downplays 'tech manipulation' By Baek Byung-yeul With the competition for chip refinement processes reaching a breaking point, market competition between memory chip king Samsung Electronics and U.S. chipmaker Micron seems to be heating up over how small they can make their DRAM memory chips. During a conference call for first-quarter earnings held April 26, a Samsung Electronics executive unveiled details about the production schedule of its 10-nanometer-level DRAM memory chip. "We are already using EUV, partially in the D1z process, but we will be starting EUV application for production starting from the D1a DRAM, which is the lower side of the 14-nano, in order to establish and further our technology leadership," the senior vice president said during the meeting.
