Semicap is the front line of the technology war and the purest expression of China's import-substitution machine. Unlike optical modules, where Chinese firms won global markets, Chinese equipment makers sell almost entirely at home, into a protected and subsidized domestic market that happens to be the largest equipment market on earth. The result is the fastest localization ramp in the industry: domestic tools went from 7% of Chinese fab purchases in 2020 to 35% in 2025, beating Beijing's own 30% target. The investment question has accordingly shifted from "can they build the tools" to "what are these franchises worth once the subsidized land-grab phase ends," because margin compression is already visible across every major name.

The segment at a glance

Wafer fab equipment (WFE) spans lithography, etch, deposition (CVD/ALD/PVD/epitaxy), cleaning and stripping, CMP, ion implant, thermal processing, track (coat/develop), and metrology and inspection, plus fab-adjacent subsystems (RF power, vacuum, gas delivery, temperature control). Back-end equipment covers test (ATE, handlers, probers) and assembly and packaging (bonders, dicing, molding), with advanced packaging blurring the front/back boundary.
