WESEMiBAY Semiconductor Ecosystem Expo 2026Dates, Registration & Visitor Guide

What is WESEMiBAY Semiconductor Ecosystem Expo?

WESEMiBAY (湾芯展, "Bay Chip Expo") is Shenzhen's own semiconductor show. It was created under the city's "one industry cluster, one expo" policy. The Shenzhen Semiconductor and IC Industry Alliance and the state-owned Shenzhen Major Industry Investment Group organise it, Shenzhen Xinmeng Exhibition runs it, and China International Engineering Consulting Corporation provides guidance. It is held at the Futian Convention & Exhibition Center in central Shenzhen, not the Bao'an venue. The organizers pitch it as a way into the Greater Bay Area's planned wafer fabs and their equipment and materials budgets.

The show is organised around the chip-making chain. There are zones for wafer-fab equipment (etch, deposition, metrology), materials and components such as pumps, valves and vacuum parts; compound semiconductors (SiC, GaN, GaAs, gallium oxide, diamond); advanced packaging, including glass substrates and TGV; and, in 2026, IC design alongside AI infrastructure such as AI chips, servers, liquid cooling and green computing.

The 2025 edition had more than 600 exhibitors and over 112,300 visitors. Exhibitors included global toolmakers Applied Materials, Lam Research, KLA, TEL, DISCO, Nikon, Merck, ZEISS and Edwards. They showed alongside Chinese equipment and chip companies such as NAURA, SiCarrier, Piotech, SMEE, China Resources Microelectronics and Huatian. SiCarrier, a Shenzhen toolmaker, drew the biggest crowds with 16 process and metrology tools. Shenzhen's Wanliyan launched a 90 GHz real-time oscilloscope there. Exhibitors released around 2,500 new products, and the organizer said about 5,000 buyers from companies including SMIC, Samsung, SK hynix, YMTC, BYD, Foxconn and DJI took part in one-to-one matchmaking. By October 2025 Applied Materials, KLA, TEL, NAURA, Piotech and ACM Research had already rebooked for 2026.

The WESEMiBAY Semiconductor Conference runs alongside. In 2025 that meant the Chip Conference, the 9th International Advanced Lithography Technology Symposium and more than 30 forums on design, manufacturing, packaging, materials, equipment and investment, with speakers from ASML, Applied Materials and Canon. The annual WESEMiBAY awards are also presented. For people following China's push for home-grown chip equipment, it is the clearest single view of which Chinese toolmakers are competing with the global suppliers, and it sits next to Shenzhen's large IC-design and electronics customer base.
