Piotech to acquire Wuxi Shangji amid China chip consolidation push
Synopsis
State-backed Piotech is moving to absorb Wuxi Shangji Semiconductor in a deal that would fuse thin-film deposition, PVD, etching, and CVD capabilities under one roof — a direct response to US chip export curbs and a sign that China's semiconductor equipment sector is shifting from fragmented startups to scaled national champions.
Key Takeaways
Piotech (formally Tuojing Technology ), listed in Shanghai , filed plans on 29 June 2026 to acquire a controlling stake in Wuxi Shangji Semiconductor .
The deal will be funded via share issuance and cash; a final price has not been determined as the transaction is in early stages.
China 's National Integrated Circuit Industry Investment Fund (the Big Fund ) held a 16.5 per cent stake in Piotech as of late March , signalling state backing for the move.
Wuxi Shangji , founded in 2021 , makes PVD , etching, and CVD equipment serving power devices, advanced packaging, compound semiconductors, and integrated circuits.
The acquisition expands Piotech 's portfolio beyond PECVD and ALD equipment into a broader range of front-end chip manufacturing process steps.
The deal reflects a broader consolidation trend in China 's chip equipment sector as domestic toolmakers seek scale to counter US export restrictions.
Shanghai-listed chip equipment maker Piotech (formally known as Tuojing Technology) announced on Saturday, 29 June 2026 that it plans to acquire a controlling stake in Wuxi Shangji Semiconductor, marking one of the most significant consolidation moves yet in China's state-driven push for semiconductor self-sufficiency under intensifying US export curbs.
The deal structure
According to a filing submitted to the stock exchange, Piotech intends to fund the acquisition through a combination of share issuance and cash, alongside the raising of supporting funds. The transaction remains in its early stages, and a final price has not yet been determined, the company said. No timeline for completion was disclosed.
State backing and strategic rationale
Piotech's largest shareholder is China's state-backed National Integrated Circuit Industry Investment Fund — widely known as the Big Fund — which held a 16.5 per cent stake as of late March, according to the company's first-quarter report. The acquisition is designed to help Piotech expand beyond its core strength in thin-film deposition equipment — including PECVD (plasma-enhanced chemical vapour deposition) and ALD (atomic layer deposition) — as well as wafer-bonding technologies used in three-dimensional chip integration.
What Wuxi Shangji brings to the table
Founded in 2021, Wuxi Shangji Semiconductor develops PVD (physical vapour deposition), etching, and CVD (chemical vapour deposition) equipment, according to its annual report. Its products serve a broad range of sectors including power devices, advanced packaging, compound semiconductors, and integrated circuits — capabilities that complement rather than duplicate Piotech's existing portfolio.
Why it matters
China's semiconductor equipment sector is entering a consolidation phase, with state-backed toolmakers absorbing smaller domestic rivals to build scaled national champions capable of competing with — or circumventing — restrictions imposed by Washington. The Big Fund's presence on Piotech's cap table signals that this deal carries implicit state endorsement, accelerating the pace at which domestic toolmakers can offer a fuller equipment stack to Chinese chipmakers locked out of foreign suppliers.
What's next
With deal terms still being negotiated and a final price undisclosed, investors and industry observers will be watching for the formal valuation and any regulatory approvals required. The combined entity, if the deal closes, would cover a wider range of front-end semiconductor process steps — potentially positioning it as a more credible alternative to equipment from restricted foreign vendors. How quickly Piotech can integrate Wuxi Shangji's technology and scale production will be the critical test of this consolidation strategy.
Point of View
That company scales, then absorbs complementary startups to cover more process steps. What mainstream coverage often misses is that the real bottleneck for Chinese chipmakers is not any single piece of equipment but the absence of a full, integrated toolset — and deals like this directly target that gap. The combination of Piotech's deposition and bonding expertise with Wuxi Shangji's PVD, etching, and CVD capabilities moves the needle toward a more self-contained domestic supply chain. Investors should watch whether the combined entity can win qualifications at leading Chinese fabs, which would be the clearest signal that consolidation is translating into real manufacturing capability.

Frequently Asked Questions
What is Piotech's plan to acquire Wuxi Shangji Semiconductor?
Piotech plans to acquire a controlling stake in Wuxi Shangji Semiconductor through a combination of share issuance and cash, with supporting funds also to be raised. The transaction is at an early stage and a final price has not been set, according to the company's stock exchange filing dated 29 June 2026 .
What role does China's Big Fund play in the Piotech deal?
The Big Fund — formally the National Integrated Circuit Industry Investment Fund — is Piotech 's largest shareholder, holding a 16.5 per cent stake as of late March . Its presence signals implicit state endorsement of the acquisition as part of China 's broader semiconductor self-sufficiency drive.
What equipment does Wuxi Shangji Semiconductor make?
Founded in 2021 , Wuxi Shangji Semiconductor develops PVD (physical vapour deposition), etching, and CVD (chemical vapour deposition) equipment. Its products serve power devices, advanced packaging, compound semiconductors, and integrated circuits.
Why is China consolidating its chip equipment sector?
China 's semiconductor equipment sector is consolidating as state-backed toolmakers absorb smaller rivals to build scaled national champions capable of supplying a broader range of process tools. This is a direct response to US export curbs that restrict Chinese chipmakers' access to foreign equipment.
How does the Piotech-Wuxi Shangji deal affect China's semiconductor ambitions?
The deal would give Piotech a more complete equipment portfolio spanning thin-film deposition ( PECVD , ALD ), wafer bonding, PVD , etching, and CVD — covering more front-end chip manufacturing steps domestically. If the combined entity wins qualifications at major Chinese fabs, it would meaningfully reduce reliance on restricted foreign suppliers.
