South Korea's Exports Surge in August Driven by Semiconductors; SK Hynix Leads 1c DRAM Production, Samsung Confirms Investment for 2025 Launch; Both Giants to Adopt Next-Gen Photoresist Technologies

In the first 10 days of August 2024, South Korea's exports increased by 16.7% year-on-year, reaching $15.5 billion, driven primarily by a significant 42.1% surge in semiconductor exports. Other sectors like petroleum products and automobiles also saw growth, with automobile exports rising sharply by 63.9%. However, machinery product exports declined by 10.6%. Imports grew by 13.4% to $18.4 billion, resulting in a trade deficit of $2.9 billion. Notably, exports to major trading partners China and the United States increased by 10.7% and 27.7%, respectively. This continues a trend of export growth, marking the tenth consecutive month of gains as of July.



SK hynix has announced it will begin mass production of its 6th generation (1c) 10nm class DRAM in the third quarter of 2024, ahead of Samsung Electronics, which plans to start production by the end of the year. SK hynix has already established an internal road map to achieve customer certification and start production, potentially positioning itself to capture significant demand from major tech companies like Amazon and Microsoft once Intel certifies its DRAM for server use. The 6th generation DRAM, utilizing advanced Extreme Ultraviolet (EUV) lithography, promises higher chip yields and improved power efficiency compared to previous generations.

Samsung has confirmed its investment in the Pyeongtaek P4 plant for the production of 6th-generation 1c DRAM, with plans to begin mass production in June 2025. This next-generation DRAM, which uses 10nm-class technology, is still not commercialized globally, but Samsung and SK hynix are preparing for its mass production. Despite initial delays due to a downturn in the semiconductor market, Samsung is now expanding its P4 facility, initially installing NAND flash equipment and confirming plans for 1c DRAM production. The company also anticipates launching HBM4 using 1c DRAM by the second half of 2025, aligning with forecasts of significant growth in the memory industry's revenues.

Both Samsung and K Hynix plans to adopt Inpria's metal oxide resist (MOR) technology in the production of 1c DRAM, utilizing MOR to draw the finest lines on one of the five to six  EUV layers in the 1c DRAM. This adoption aims to enhance performance and reduce costs in future DRAMs. MOR is seen as a next-generation alternative to the chemically amplified resist (CAR) currently used in advanced chip lithography, addressing CAR's limitations in resolution, etching resistance, and line edge roughness. 

In 2021, JSR Corporation announced its acquisition of Inpria Corporation, the leading innovator in metal oxide photoresist technology for EUV lithography, solidifying its focus on advancing semiconductor materials.

Samsung is considering multiple suppliers for its EUV MOR photoresist needs beyond Inpria, including companies like Dupont, Dongjin Semichem, and Samsung SDI. These alternatives are currently being tested as the company explores the best options for its 1c DRAM production. 

Lam Research refers to its inorganic photoresist technology as "dry resist," which reportedly is expected to be supplied for Gen 7 10nm (1d) DRAM production, anticipated to launch next year. This dry resist is deposited by ALD and represents a further evolution in PR technology, potentially offering enhanced performance for the next generation of DRAM manufacturing.

Samsung Electronics Is Pushing Hard to Bring Monolithic 3D DRAM to HVM by 2025

Samsung Electronics has been enjoying its DRAM market leader position for about 30 years now. To retain the position further, it has intensified its R&D of monolithic 3D DRAMs to bring them to HVM by 2025.




DRAM’s performance boost based on scaling the cell size or pitch is approaching a physical limit for cramming more cells in a limited space. Additionally, the ultra-high aspect ratio capacitors may collapse leading to compromised device reliability. Therefore, switching from current 2D DRAMs to next-generation monolithic 3D DRAMs seems inevitable.

Samsung has reportedly intensified its R&D on stacking DRAM cells on top of each other in a monolithic fashion, unlike in the case of high-bandwidth memory (HBM), wherein multiple dies are stacked atop each other.

Besides High-k/Metal Gate transistor technology, Samsung is also considering adopting FinFET or gate-all-around (GAA) technology for the DRAM cell transistor to attain better electrostatic control of the charge flow within the channel with the gate electrode.

Micron Technology and SK Hynix are also reportedly developing monolithic 3D DRAMs. Micron recently filed a patent for a monolithic 3D DRAM that is different from that of Samsung. Micron’s approach is to change the shapes of the transistor and capacitor without laying down a cell. Major equipment manufacturers such as Applied Materials and Lam Research are also developing solutions for the monolithic 3D DRAMs.

South Korean equipment makers recorded mixed results in the first quarter of 2021

출처 : THE ELEC, Korea Electronics Industry Media(http://thelec.net) - South Korean equipment makers recorded mixed results in the first quarter of 2021.

  • Fab equipment vendors posted high growth, while display equipment firms underperformed.
  • Fab equipment makers benefited from aggressive spending by semiconductor companies.
  • CVD/ALD equipment companies showed good growth, see below (Jusung, Wonik IPD, Eugene Technologies

Semes, Samsung Electronics’ fab equipment subsidiary, recorded 870.6 billion won in sales, an increase of 62.3% from a year prior. It recorded 112.8 billion won in operating income, an increase of 40.5% over the same time period. The growth likely stems from Samsung starting to put in equipment to its P2 chip line at its Pyeontaek plant during the quarter. Overheat transport accounted for 60% of the sales recorded by Semes during the quarter.

SFA recorded 355.6 billion won in sales and 42.3 billion won in operating income, a drop of 3.3% and 1.6%, respectively, a year prior. Non-display business accounted for 65.1% of its sales. SFA, which previously focused on display kits, managed to record level earnings to a year prior thanks to other business areas.


Wonik IPS recorded 254.5 billion won in revenue and 24.2 billion won in operating income, a surge of 39.9% and 68.1%, respectively, from a year prior. The firm previously focused on fab equipment for use in memory chip production. But it has begun supplying kits for foundry beginning last year, which helped growth.

Eugene Technology recorded 100.7 billion won in revenue and 30.7 billion won in operating income. The company recorded an operating margin rate of 30.5%. Its LPCVD equipment supplied to SK Hynix for the latter’s M16 DRAM fab led the growth.

Jusung Engineering posted 75.3 billion won in sales in the quarter, double that of the year prior. It turned a profit from a year prior and posted 16 billion won in operating income. The company won the order for atomic layer deposition kits from SK Hynix for use in next-generation DRAMs. Jusung is the sole supplier of the kits.

Hanmi Semiconductor recorded 70.9 billion won in sales, a jump of 79% from a year prior. Its operating income increased 160% year-on-year to 19.3 billion won. It won 22 orders during the quarter. It has signed supply deals with SK Hynix, Amkor Technology Korea, ASE, NXP, Nanya, SPIL and others for a combined worth of 87 billion won.

YIK recorded 67.5 billion won in sales and 9.7 billion won in operating income, a jump of 99.7% and 177.1%, respectively, from a year prior. The firm mainly provides electrical die sorting equipment. The firm is seeing more orders from Samsung, having signed a 155.3 billion won deal with the tech giant in the first quarter alone.

South Korean fab equipment makers are expected to post solid growth throughout 2021 from increased spending this year by Samsung and SK Hynix. SK Hynix had said in the conference call for the first quarter that it plans to execute some of its spending it planned for 2022 earlier to this year.

SEMI is expecting global fab equipment spending to increase 15.5% this year to US$70 billion. Meanwhile, South Korean display equipment makers underperformed during the first quarter.

Samsung Display and LG Display have been conservative with their spending due to uncertainties surrounding the display market. But increased spending in OLED from Chinese panel makers such as BOE and Tianma staved off a huge dip in profitability.

Only few companies recorded growth, such as AP Systems, which saw sales drop 6.9% year-on-year but operating income surge 53.2% over the same time period. The company benefited from laser annealing equipment supplied to BOE for the B12 line.

Youngwoo DSP saw a surge in its operating income from supplies to its Chinese customers. KC Tech saw sales jump 21.1% but operating income remained flat. Top Engineering saw 9.6 billion won in operating loss from the 6.1 billion won operating loss posted by subsidiary Powerlogics. Dong A Eltek recorded 2.3 billion won in operating loss, though sales doubled. The firm said increased cost from the pandemic stunted growth.

Charm Engineering continued to record loss. HB Technology, Toptec and Philoptics all turned to the red. 

Local display equipment makers are expected to see a turnaround starting in the fourth quarter when Samsung Display and LG Display decide on new spending plans around the same time.

Innovation and IP filing in Atomic Layer Deposition has moved from Memory to Logic

By studying the filing of IP world wide one can clearly see the trend how innovation in Atomic Layer Deposition (ALD) has moved from Memory to Logic. During the introduction of ALD (2003 to 2006) in high volume manufacturing of DRAM on 300 mm wafers most IP was filed by Samsung, Micron and SK Hynix. 10 years later (2013-2018) the IP filing lead has been taken over by Logic MPU manufacturers TSMC, Intel and Globalfoundries.
