Samsung Chip Union Ratifies $26.6 Billion Bonus Deal With 74% Vote, Averting 18-Day Strike at World's Largest Memory Maker

74% Yes Vote Closes Out an 18-Day Strike Threat

Samsung Electronics' largest union ratified a 2026 wage agreement on May 27, with about 74% of voting members in favor, formally ending a labor standoff that was 90 minutes from triggering an 18-day general strike at the world's largest memory chipmaker. The vote ran from May 22 through Wednesday morning and drew 62,616 ballots, with 73.7% support, according to Bloomberg and The Korea Herald.

The same union rally in April had already pulled night-shift fab output down by 58%, according to internal figures reported by Tom's Hardware, giving customers and equipment suppliers a preview of what a full walkout would have done to the global memory supply chain.

The Math: 10.5% of Chip Profit, 10 Years, $26.6 Billion Pool

The agreement allocates 10.5% of Samsung's semiconductor division operating profit as stock-based bonuses, plus an additional 1.5% in cash and a 6.2% average wage increase. The program runs for 10 years and is contingent on the chip division clearing operating-profit thresholds: more than 200 trillion won (about $132 billion) per year from 2026 through 2028, and 100 trillion won per year from 2029 through 2035.

Bloomberg projects Samsung's 2026 operating profit at roughly 330 trillion won, which would translate to a bonus pool of about 40 trillion won — roughly $26.6 billion — spread across the chip division's 78,000 employees. Average payouts could land near $340,000, with top memory roles approaching 600 million won ($400,000), Tom's Hardware reports.

Memory Wins, Foundry and TSP Stew

The deal closes the strike risk but widens a pay gap inside Samsung. Memory-division staff stand to collect up to $400,000, while smartphone, TV, and appliance employees are looking at payouts closer to $4,000. Samsung's smaller, non-chip union approved the agreement with only about 21% support.

That resentment has already produced work slowdowns inside Samsung's foundry and TSP (Test & Package) divisions, with meetings canceled and major-project decisions stalled, according to Tom's Hardware. Samsung DX head TM Roh acknowledged in an internal memo that many employees feel "alienated" and pledged to review what needs to change "on the front lines."

HBM4 Ramp and the Nvidia Rubin Risk

The TSP division handles back-end packaging and test for high-bandwidth memory, including hybrid bonding and TSV (through-silicon via) operations. Disruptions there threaten Samsung's HBM4 ramp for Nvidia's Rubin AI accelerators, which is scheduled to ship in the second half of 2026.

The vote also landed on a milestone day for AI memory: SK hynix and Micron both crossed the $1 trillion market-cap mark on Wednesday, joining Samsung — a signal of how much value markets are pricing into uninterrupted HBM output, and how much downside a Samsung-side stumble would carry.

Why Equipment Vendors Were Watching

Samsung is one of the largest single buyers of wafer fab equipment globally, with 2026 worldwide WFE spending tracking to $135.2 billion, up 9% year over year, per SEMI. SEMI's April 2026 update separately projects 300mm fab equipment spending will climb 18% to $133 billion this year, with DRAM equipment up 15.1% and NAND equipment up 12.7%.

For Applied Materials, Lam Research, Tokyo Electron, ASML, and ASM International, an 18-day Samsung strike would have rippled into tool-acceptance schedules, wafer-out targets used in service contracts, and the timing of follow-on equipment orders tied to capacity utilization. The 10-year bonus framework locks in a labor cost structure for the chip division through 2035 — useful visibility for vendors planning long-cycle ALD and etch tool builds against Samsung's 2nm GAA and HBM4/4E roadmaps.

What This Means for Plasma Processing and Thin Film Deposition

Samsung memory and foundry fabs are anchor accounts for plasma etch (CCP, ICP, atomic layer etch), PECVD dielectric stacks, and ALD high-k and metal films used across DRAM capacitors, 3D NAND staircase and channel layers, and 2nm GAA nanosheet transistors. A multi-week strike would have idled the plasma sources, RF generators, and gas-delivery panels on hundreds of installed tools, with knock-on effects on consumables — sputtering targets, precursor canisters, vacuum pump service contracts — across the equipment supply chain.

The TSP slowdown is the more pointed risk now. HBM4 base-die manufacturing and 16-Hi stacking rely on advanced deposition and etch steps to thin wafers toward 30 micrometers and to land hybrid-bond pads at sub-micron pitch. Each delay there shifts when Nvidia Rubin accelerator memory ships, and when packaging tool vendors — Applied Materials, Lam Research, ASM International, BESI, and EV Group among them — book follow-on system orders against Samsung's hybrid-bonding capacity plan.

For NineScrolls and the broader plasma processing and thin film deposition supply chain — plasma sources, RF match networks, mass flow controllers, turbomolecular and dry pumps, process monitoring, and target/precursor suppliers — the May 27 vote removes the near-term cliff but leaves the slower problem: a chip-division pay structure tied to 200 trillion won profit targets means Samsung will keep WFE spending aggressive on memory and HBM through at least 2028, even as foundry-side morale issues stretch the qualification cycle on new deposition and etch tools.
