Samsung to use chip making tech favoured by SK Hynix

Samsung Electronics plans to make use of a chip making know-how championed by rival SK Hynix, 5 individuals stated, because the world’s high reminiscence chipmaker seeks to catch up within the race to provide high-end chips used to energy synthetic intelligence.

The demand for prime bandwidth reminiscence (HBM) chips has boomed with the rising recognition of generative AI. However Samsung, not like friends SK Hynix and Micron Expertise, has been conspicuous by its absence in any dealmaking with AI chip chief Nvidia to produce newest HBM chips.

One of many causes Samsung has fallen behind is its choice to stay with chip making know-how known as non-conductive movie (NCF) that causes some manufacturing points, whereas Hynix switched to the mass reflow molded underfill (MR-MUF) methodology to handle NCF’s weak point, based on analysts and trade watchers.

Samsung, nonetheless, has not too long ago issued buy orders for chipmaking gear designed to deal with MUF approach, three sources with direct information of the matter stated.

“Samsung needed to do one thing to ramp up its HBM (manufacturing) yields … adopting MUF approach is a little bit little bit of swallow-your-pride sort factor for Samsung, as a result of it ended up following the approach first utilized by SK Hynix,” one of many sources stated.

Samsung stated its NCF know-how is an “optimum answer” for HBM merchandise and could be utilized in its new HBM3E chips. “We’re finishing up our HBM3E product enterprise as deliberate,” Samsung stated in response to Reuters’ questions on the article.

After the article was printed, Samsung issued an announcement saying “rumours that Samsung will apply MR-MUF to its HBM manufacturing aren’t true”.

The HBM3 and HBM3E are the most recent variations of excessive bandwidth reminiscence chips which are bundled with core microprocessor chips to assist course of huge quantities of knowledge in generative AI.

Samsung’s HBM3 chip manufacturing yields stand at about 10-20%, lagging SK Hynix that has secured about 60-70% yield charges for its HBM3 manufacturing, based on a number of analysts.

Based on one of many sources, Samsung is already in talks with materials producers, together with Japan’s Nagase to supply MUF supplies. However mass manufacturing of the high-end chips utilizing MUF is unlikely to be prepared till subsequent yr on the earliest, as Samsung must run extra checks, the individual added.

The three sources, talked about above, additionally stated Samsung plans to make use of each NCF and MUF strategies for its newest HBM chip.

All sources spoke on situation of anonymity as the knowledge isn’t public.

Nvidia and Nagase declined to remark.

Any transfer by Samsung to make use of MUF would underscore the rising strain it faces within the AI chip race, with the HBM chip market, based on analysis agency TrendForce, anticipated to greater than double this yr to just about $9 billion amid AI-related demand.

NCF VERSUS MUF

The non-conductive movie chip manufacturing know-how has been broadly utilized by chipmakers to stack a number of layers of chips in a compact excessive bandwidth reminiscence chipset, as utilizing thermally compressed skinny movie helps minimise area between stacked chips.

However there are sometimes issues linked to adhesive supplies as manufacturing will get sophisticated as extra layers are added. Samsung says its newest HBM3E chip has 12 chip layers. Chipmakers have been in search of alternate options to handle such weaknesses.

SK Hynix efficiently switched to the mass reflow molded underfill approach forward of others, changing into the primary vendor to produce HBM3 chips to Nvidia.

SK Hynix’s market share in HBM3 and extra superior HBM merchandise for Nvidia is estimated at above 80% this yr, based on Jeff Kim, an analyst at KB Securities.

Micron joined the excessive bandwidth reminiscence chip race final month, asserting that its newest HBM3E chip shall be adopted by Nvidia to energy the latter’s H200 Tensor chips which is able to start delivery within the second quarter.

Samsung’s HBM3 sequence haven’t but handed Nvidia’s qualification for provide offers, based on one of many 4 sources and one other individual with information of the dialogue.

Its setback within the AI chip race has additionally been observed by traders, with its shares falling 7% this yr, lagging SK Hynix and Micron that are up 17% and 14%, respectively.

On Wednesday, SK Hynix shares fell 2%, whereas Samsung rose 1%, beating a 0.4% rise within the broader market.
