Bosch spins chips into own unit as memory costs and grid limits squeeze supply chains

Bosch announced the restructuring on 3 November, according to The Next Web. The unit will be called Semiconductors and will stay inside Bosch rather than becoming a separate company. Chip work currently sits in Mobility Electronics, which keeps making electronic control units for vehicles.

The €5bn target for 2030 is roughly a bet that Bosch can sell more silicon outside cars. The company plans to open its manufacturing to external clients and expand its foundry business, producing chips for other firms. Bosch lists robotics, factory automation and AI data centres as target markets, plus consumer devices such as phones and wearables.

"With the founding of a dedicated unit, we are opening a new chapter in our more than 60-year semiconductor history," said Erik Rein, who heads Bosch's chip business, in the announcement carried by The Next Web. Bosch deputy chairman Markus Heyn said the company's sensors are "the key" to its products and "the technological basis" for customers' innovations.

What Bosch actually makes

Bosch is a leading supplier of MEMS sensors, the miniature motion and pressure sensors used in smartphones and robots. It also produces silicon carbide chips and custom circuits for power systems. Its manufacturing footprint spans around 40 chip sites worldwide, The Next Web reported. Bosch has invested about €3bn in wafer plants in Dresden and Reutlingen. It is spending around $2bn to convert the Roseville, California site to silicon carbide production. The company also plans to expand its test centre in Penang, Malaysia, through the mid-2030s. It holds a 10% stake in ESMC, the TSMC-led joint venture building a factory in Dresden.

None of that is new capacity in the legacy sense: the pitch is specialised parts and foundry access, not commodity logic.

The timing is not accidental. European carmakers spent part of the autumn managing shortages during the Nexperia dispute, which exposed how few suppliers the industry depends on. Offering outside capacity could help diversify Europe's chip supply. It would also give Bosch new buyers for its own technology.

The memory squeeze behind the foundry push

Bosch's move lands in a market where the scarce component is memory, not automotive sensors. Apple chief executive John Ternus told analysts on Monday that memory pricing is "unprecedented", according to The Guardian. He said costs in the December quarter would be higher than in the previous three months. Apple's shares fell 2.75% in after-hours trading.

The numbers are stark. Apple's inventory rose from $11.09bn in its fiscal third quarter to $14.54bn in the fourth, a 31.1% jump. That was up 154.3% from $5.72bn a year earlier, TechCrunch reported, citing the earnings released on Monday. Apple guided to a 45% to 46% gross margin for the December quarter, down from 47.9% in the September quarter, largely because of memory costs. Ternus said manufacturing purchase obligations had increased by $33bn from June to the September quarter. Apple raised prices on Mac and iPad at the end of June and on iPhones in September, which it says partly offsets the cost. iPad revenue of $6.2bn missed analyst expectations of $6.7bn and fell 10% year on year, which Apple blamed on supply constraints.

"The grid is the hardest to fix because it is structural: new grid infrastructure takes five to 15 years to build, while a data center takes one to three," Martina Raveni, senior analyst at GlobalData, told Data Center Knowledge.

Supply is not loosening soon. Semiconductor Engineering's week in review, published on 30 October, reported that SK hynix expects memory constraints to persist through 2030. DRAM and HBM volumes are effectively sold out through 2029. Samsung expects tight supply through 2028 and says its 2027 HBM supply is already sold out. Advanced packaging is tight too: TSMC is reportedly considering a 20% price increase for CoWoS.

Black market prices and a Huawei workaround

The shortage has a grey edge inside China. Huawei is telling some customers to source memory for its AI chips themselves, according to The Information as cited by The Decoder. That effectively pushes buyers toward the black market. Huawei plans to launch the Ascend 960DT early next year and says it will double the performance of current chips. But Chinese suppliers cannot produce enough HBM, and U.S. rules block direct purchases from Samsung and SK hynix, which together control more than 80% of the global market.

Smugglers bundle HBM with cheap server processors that fall below export thresholds and ship the packages through Hong Kong, Tom's Hardware reported on 3 November, again citing The Information. In Shenzhen workshops, technicians heat the boards to soften solder and lift the memory chips off, discarding the rest. The failure rate is high, but the margins justify it.

A Shenzhen broker told The Information, as relayed by The Decoder, that smuggled HBM3E prices have jumped from a few hundred dollars to around $4,000 per unit in a year. Each AI chip needs six to eight units, so memory alone can cost up to $32,000. South Korea's customs authority had uncovered trade violations by May, already above the previous full-year record. A third of those involved strategic goods such as chips.

Power, not just wafers, sets the pace

Even where chips can be bought, data centres are waiting on electricity. Projects that broke ground between the third quarter of 2025 and the third quarter of 2026 waited an average of just over two years after being announced. That compares with about 18 months for projects started between early 2020 and mid-2025, according to GlobalData figures reported by Data Center Knowledge on 3 November.

Luis Fernandes, IDC senior research manager for cloud and data centres, told Data Center Knowledge that grid access is "by a long shot the biggest cause for delay in projects". GlobalData forecasts annual data centre electricity consumption rising from 590 terawatt-hours in 2025 to 1,520 TWh in 2030. Developers in Europe's main hubs can wait up to a decade for a connection, Raveni said. Skilled labour shortages push some schedules back by around a year.

That changes what fab expansion is for. Bosch's foundry pitch is aimed at robotics, automation and AI data centres. But those customers are themselves constrained by grid connections and memory allocations. Capacity announced today may not find a buyer at the price Bosch hopes until the bottlenecks clear.

China's alternative route

China is trying to route around the memory wall with a different DRAM architecture. CXMT plans to send customers samples of its first server-grade DRAM built on the 4F² design by the end of this year. That is according to a summary of its earnings briefing released on Saturday and reported by the South China Morning Post on 2 November. No mass production timeline was given; the company said commercial rollout depends on client validation and market demand.

The 4F² approach is one Micron has chosen to bypass, the SCMP noted. That puts CXMT on a separate technical path under cost and export pressure. Separately, Reuters reported via Semiconductor Engineering that CXMT plans limited HBM3E production despite yields of just 20% to 30%. Anthropic warned in its IPO filing that HBM shortages and limited TSMC capacity could constrain AI expansion.

Optical links are the other answer to cramped systems. Marvell agreed to acquire Lumentum in an all-stock deal with an implied enterprise value of $115bn, EE Times reported on 3 November. The deal combines Marvell's custom silicon, networking and interconnect work with Lumentum's lasers, transceivers and optical circuit switching. It is expected to close in the first half of 2028, subject to shareholder and regulatory approvals, per Semiconductor Engineering.

Marvell chief executive Matt Murphy said AI infrastructure is shifting toward optical connectivity, in comments carried by EE Times. Lumentum chief executive Michael Hurlston put the opportunity at "$550 billion". Analysts quoted by Reuters via EE Times questioned whether Marvell is paying too much. That is the standard reaction to any $115bn all-stock bet.

For Bosch, the contrast matters. Its new division sells sensors, power chips and foundry slots, not memory or optics. The €5bn goal by 2030 depends on customers outside autos arriving on schedule. Those customers face binding constraints: DRAM allocation, electricity connections and, in China, the willingness of buyers to source parts through informal channels.
