AMEC buys control of CMP specialist Sizone, backed by 1.5B yuan raise
What's the deal? Advanced Micro-Fabrication Equipment Inc. China (AMEC) is acquiring a 64.69% controlling stake in Hangzhou Sizone (Zhonggui) for 1.576 billion yuan, paid through a mix of share issuance and cash. On 7 July 2026, AMEC said it had completed the supporting financing phase, raising nearly 1.5 billion yuan.
The terms: Sizone's full equity was appraised at 2.501 billion yuan and set at 2.436 billion yuan after negotiation. AMEC bought the stake from 41 counterparties, including Hangzhou Zhongxingui and Lin'an Zhongxingui, and will fold Sizone into its consolidated accounts as a controlled subsidiary.
The financing: AMEC placed 5.1568 million new shares at 290.88 yuan each with four investors, raising about 1.499 billion yuan. The shares are restricted and unlock in batches. Funds go to Sizone's R&D and industrialization centre, the cash portion of the deal, and working capital.
What's the endgame? Sizone makes high-end chemical mechanical polishing (CMP) equipment and is one of the few Chinese firms to reach mass production of 12-inch high-end CMP tools. CMP is a core wet process in front-end chip manufacturing — and a gap in AMEC's line-up, which has centred on dry processes such as plasma etching and thin film deposition.
Why now? The deal marks AMEC's first controlling-stake acquisition via share issuance in over two decades, a step it framed as advancing its platform strategy. Sizone's tools span 8-inch and 12-inch wafers and address logic chips, memory, silicon wafers, and silicon carbide substrates.
The signal: The purchase reflects China's push to build a domestic semiconductor equipment stack and reduce reliance on overseas suppliers. By adding CMP to etching and deposition, AMEC widens its role across the front-end toolchain — consolidating homegrown capability under a single listed platform.
