Signal Chain × Power Chain × Actuator — Mapping where profit truly flows across global semiconductors. From physics limits to scene integration, vertical integration is the means; ecosystem authority is the end.
Under the physical limits of 2026, single-point innovation is dead. True alpha exists only at the coupling points where three value chains intersect.
From high-precision ADC sampling of physical signals, through GPU/CPU massively parallel computation, to electro-optical high-speed interconnect. The signal chain determines how the world is digitally understood.
From SiC/GaN wide-bandgap material energy capacity, through multi-phase power management precision step-down, to isolated gate drivers' high-voltage pulses. The power chain determines how the physical world is precisely actuated.
Converting digital commands into physical-world displacement, torque, and photon flow. The actuator chain is the ultimate convergence of bits and watts — the moment algorithms become kinetic energy.
A "coupling point" emerges when physical requirements (800V high-voltage, 1.6T optical speed, AI thermal limits at 1,500W+) force previously isolated chips into vertical integration, thereby creating an entirely new market segment. The marginal returns of pure compute chips (Haiguang) or pure materials (SICC) are diminishing — the real premium flows to companies that collect tolls at the intersection of bits and watts.
A hidden law of human technological progress: the information bit chain and the energy watt chain develop in alternation, then couple together to meet market demand. Coupling points are new phenomena born at the intersection of energy and information chains — created when traditional industrial scenarios undergo digital transformation.
