Samsung begins mass production of 14 nm DRAM with EUV . technology

In an effort to cement its leadership position in the memory industry, Samsung Electronics Co., the world's largest memory chip maker, said on October 12 that it has begun mass production of 14-inch DRAM DRAMs. smallest nanometer (nm) used in EUV (Extreme Ultraviolet Litography) technology.

EUV technology commonly referred to as Ultraviolet lithography is a next generation lithography technology that utilizes a wide range of ultraviolet wavelengths, spanning about 2% of the FWHM bandwidth of approximately 13.5 nm, which produces chip generation built on 7nm process.

Samsung shipped 1 million 10nm (D1x) DDR4 (Double Date Rate 4) DRAM chips manufactured with this technology in March 2020 for the first time in the industry.

The Korean technology giant said that EUV technology helps to reduce repetitive steps in repeated engraving and improves the accuracy of chip patterns, resulting in better performance and higher productivity, as well as Shorten development time.

Samsung hopes this latest process will increase productivity by 20% and reduce power consumption by almost 20%. The company will also start producing DDR5. DDR5 is the next generation DRAM standard that is fast and dense with lower power consumption than the DDR4 model. DDR5 is optimized for use in data-intensive applications such as big data, artificial intelligence, and machine learning.

In a statement, Lee Joo-young, Senior Vice President and Head of Product and DRAM Technology at Samsung Electronics, said that Samsung is setting a new technological milestone with the multilayer EUV, which enables the collection of extremely small a semiconductor process to produce 14nm process chips, a feat not possible with the conventional argon fluoride process. The 14nm index is understood as the size of a transistor (transistor) in the number of hundreds of millions of transistors integrated into a processor chip.
