Samsung Electronics Co. announced on Tuesday it has bagged a 2-nanometer AI chip foundry and package turnkey order from Preferred Networks Inc., a Japanese AI application developer, a deal the world’s No. 1 memory chipmaker said would contribute to expanding South Korea’s foundry ecosystem.
Under the contract, Samsung will manufacture AI accelerators using the 2nm foundry process based on its proprietary Gate-All-Around (GAA) technology and the advanced 2.5-dimensional packaging service. It did not disclose the deal size.
Gaonchips Co., a domestic fabless company, designs the accelerator.
Samsung flagged the foundry and packaging service order as the outcome of its collaboration with domestic chip designers aimed at strengthening the country’s foundry market.
Other domestic fabless startups such as Telechips, ABOV Semiconductor and Rebellions Inc. have outsourced chip manufacturing to Samsung. They are expanding their partnership to develop next-generation AI chips.
“This order is pivotal as it validates Samsung’s 2nm GAA process technology and advanced package technology as an ideal solution for next-generation AI accelerators,” Song Taejoong, corporate vice president and the head of Samsung’s foundry business development team, said in a press release.
Last year, Samsung launched the package turnkey service that handles the entire chip packaging process from production to tests for fabless companies.
In 2022, it started mass production of chips based on the GAA foundry technology for the first time in the world

ONE-STOP AI SOLUTIONS
Last month, Samsung said it will introduce an all-in-one integrated turnkey AI platform by 2027 to provide customers with “one-stop AI solutions” during Samsung Foundry Forum 2024 held in San Jose, California.
Samsung will deepen collaboration with Preferred Networks to develop groundbreaking AI chiplets for use in next-generation data centers and generative AI computing systems, Samsung added.
Chiplet solution refers to assembling multiple chips into a single package.
The 2.5D advanced packaging is a heterogeneous integration package technology with different types of chips such as memory, logic and sensors packed in one package to enhance interconnection speed and reduce package size.
Samsung revealed the order received from Preferred Networks at Samsung Foundry Forum 2024 and Samsung Advanced Foundry Ecosystem (SAFE) forum 2024 held in COEX, Seoul on Tuesday.

SF2Z FOR CHIP MASS PRODUCTION IN 2027
Last month, Samsung reaffirmed its plan to mass production of the 2nm process for mobile applications in 2025 before expanding to other uses in later years.
It also showcased two upgraded process nodes, SF2Z and SF4U. Mass production using the new SF2Z tech is slated for 2027, Choi Siyoung, Samsung’s foundry chief, said at the foundry forum.
SF2Z incorporates optimized backside power delivery network (BSPDN) technology, which places power rails on the backside of the wafer to eliminate bottlenecks between the power and signal lines.
1.4 NANO PROCESS
Samsung will further advance its foundry process to the cutting-edge 1.4nm node by 2027, said Choi.
“We are breaking through the limits of miniaturization and preparing for new technological innovations through cooperation with various companies,” he added.
16-LAYER HBM4
Choi Jang-seok, executive director of Samsung’s memory division, said that it is developing 16-layer HBM4 chips according to its schedule. High-bandwidth memory (HBM) is essential for generative AI thanks to its fast processing of a vast amount of data.
Samsung will launch 3D packaging services for HBM this year for the HBM4 model due in 2025, according to the company and industry sources last month.
Rebellions is developing next-generation AI accelerators based on Samsung’s 4nm process shifting from the chipmaker’s 5nm node, said Oh Jinwook, Rebellion’s chief technology officer.
ABOVE Semiconductor is producing non-volatile memory, a core component of microcontroller units, using Samsung’s 65nm process, said its Vice President Park Ho-jin. This year, it will produce advanced chips based on Samsung’s 28nm process.
Samsung will host Samsung Foundry Forum 2024 in Japan and Europe in the second half.
