What Shanghai Simgui Technology Co., Ltd. does

Shanghai Simgui Technology Co., Ltd. (上海新傲科技股份有限公司) is a Chinese high-tech enterprise founded in 2001 that manufactures silicon-on-insulator (SOI) and epitaxial (EPI) wafers for the global semiconductor industry. Operating as a core subsidiary of National Silicon Industry Group (NSIG, Shanghai STAR Market ticker 688126), Simgui produces 150mm and 200mm SOI wafers using four process technologies — SIMOX, Bonding, Simbond (proprietary, patent ZL 200510028365.6), and SSS (licensed from France's Soitec under the 2014 strategic agreement) — alongside EPI wafers for IGBT, FRD, SGT, LVMOS, HVMOS, SBD, TVS discrete devices and CMOS/Bipolar ICs. Production runs from a single Shanghai headquarters in Jiading District, supported by Class 10 cleanrooms, MRL furnaces, EVG850 bonders, ion implanters, CMP polishers, and 130-ton/day ultra-pure water infrastructure, with SOI capacity at 40,000 wafers/month and EPI capacity exceeding 400,000 4-inch-equivalent wafers/month.

The company's commercial model is direct enterprise sales of physical wafers with quote-based pricing and multi-year contracts, supplemented by custom epitaxial processing services and collaborative R&D with customers. It serves foundries and IDMs across China, Taiwan, Japan, Korea, Singapore, the US, and Europe — including GlobalFoundries, Tower Semiconductor, STMicroelectronics, BYD (for EV IGBT supply), and Soitec's downstream customer base — through technical pre-sales engagement, joint process qualification, and dedicated after-sales support. The customer base spans 5G/RF front-end, automotive power electronics (NEV/IGBT), industrial power devices, MEMS, and consumer electronics. Intellectual property includes 131 authorized patents, and the firm holds IATF16949:2016 (automotive), ISO9001, ISO14001, ISO45001, ISO50001, and VDA6.3 certifications, enabling qualification for Tier-1 automotive supply chains. Marketing is anchored on industry events (SEMICON China, the annual International RF-SOI Forum co-organized with the SOI International Industry Alliance and SEMI China) and the annual Simgui Night customer gathering.

Scale indicators6 records

Recent moves2 records

Expansion highlights5 records

Direct peers

• Soitec: French global leader in SOI wafer manufacturing (SmartCut inventor). Soitec is Simgui's technology licensor and most direct global competitor, particularly in RF-SOI and FD-SOI — both companies target the same end-customer base of foundries and IDMs for SOI substrates.

Broad incumbents

• Shin-Etsu Chemical: Japan-based global silicon wafer leader across prime, epitaxial, and SOI wafers with vastly larger scale. Shin-Etsu is a broad incumbent in the same specialty silicon wafer category Simgui operates in, with a much wider product portfolio and customer base.
• SUMCO Corporation: Japan-based leading silicon wafer manufacturer producing prime wafers and epitaxial wafers for global semiconductor makers. SUMCO competes with Simgui in the silicon wafer substrate category, particularly for advanced and power device applications.
• GlobalWafers: Taiwan-headquartered global silicon wafer producer (acquired SunEdison Semiconductor). GlobalWafers is a major broad incumbent producing prime and epitaxial wafers across multiple node sizes, competing with Simgui across multiple wafer product categories.
• Siltronic AG: Germany-based hyperpure silicon wafer manufacturer serving global semiconductor industry. Siltronic operates at a much larger scale than Simgui and competes in the broader silicon wafer substrate market that Simgui participates in.
• SK Siltron: Korea-based silicon wafer producer owned by SK Group, manufacturing prime and epitaxial wafers including SiC substrates. SK Siltron is a regional incumbent overlapping with Simgui in epitaxial wafer manufacturing for power and logic semiconductor applications.
• Okmetic: Finland-based specialty silicon wafer manufacturer (also a subsidiary of NSIG, Simgui's parent group). Okmetic focuses on MEMS and RF silicon wafers, making it a sibling company and direct comp for specialty wafer manufacturing within the NSIG ecosystem.

Emerging players

• Episil Technologies: Taiwan-based silicon epitaxial wafer manufacturer serving power semiconductor and IC markets. Episil directly competes with Simgui's EPI product line for power device applications, particularly in the broader Asian semiconductor supply chain.

Regional players

• Wafer Works: Taiwan-based silicon wafer manufacturer producing prime, epitaxial, and SOI wafers for global semiconductor customers. Wafer Works is a regional player with similar specialty wafer portfolio to Simgui, primarily serving Asia-based customers.

Others

• IQE plc: UK-based compound semiconductor wafer foundry (GaAs, InP, GaN) supplying RF, photonics, and advanced electronics markets. IQE is adjacent to Simgui's specialty wafer business through shared semiconductor substrate manufacturing expertise and overlapping RF customer base.
