Morris Chang
Morris Chang is the founder of Taiwan Semiconductor Manufacturing Company, TSMC, and the person most associated with pioneering the pure-play foundry business model, in which a company manufactures chips exclusively for other companies' designs rather than designing and selling chips of its own. Founding TSMC in 1987 after a long career in the semiconductor industry, Chang bet that there was a large market for a dedicated manufacturer that would never compete with its customers, and that bet reshaped the structure of the entire industry. Chang matters as the architect of the foundry model and the leader of the company that made it the dominant way advanced chips are manufactured.
Chang's central insight was that chip design and chip manufacturing could be separated into distinct businesses, enabling a company to make chips purely for others who design them. Traditionally, a semiconductor company both designed and manufactured its own chips, which meant that any company wanting to make a chip either needed its own expensive fab or had to go to a competitor who did. Chang recognized that a manufacturer dedicated solely to producing other companies' designs — never competing with them — would unlock a large market of companies that wanted to design chips without owning fabs. This separation of design from manufacturing is the conceptual heart of the foundry model he pioneered.
The crucial feature of Chang's model is that the foundry does not compete with its customers, which is what makes design companies willing to entrust it with their chips. A manufacturer that also designed and sold its own chips would be a competitor to the very companies bringing it their designs, creating a conflict of interest. By building TSMC as a pure manufacturer with no competing products, Chang removed that conflict, so chip designers could rely on the foundry without fear it would use or compete against their designs. This trust is essential to the model's success, and it is a direct consequence of the deliberate choice to manufacture only, never to design and sell chips in competition.
Chang's foundry model enabled the rise of the fabless industry, in which companies design chips while owning no fabrication facilities of their own. Because a trustworthy dedicated manufacturer existed, companies could focus entirely on designing chips and have TSMC build them, without the enormous capital cost of owning and running a fab. This gave rise to a whole ecosystem of fabless design companies, dramatically lowering the barrier to creating chips and letting innovation in design flourish independently of manufacturing. The fabless-plus-foundry structure that Chang's model enabled became a dominant organizing principle of the modern semiconductor industry.
Chang exemplifies how a business-model innovation can be as transformative as a technical one, restructuring an entire industry by reorganizing who does what. He did not invent a new device or process; he reconceived how the industry was organized, separating design from manufacturing in a way that created new possibilities for both. The resulting restructuring was profound, shaping the competitive landscape and enabling the modern separation of design and fabrication. Chang's legacy is this reorganization of the industry's fundamental structure, demonstrating that rethinking business arrangements can reshape a field as deeply as any technical advance.
Read Morris Chang as the architect of the foundry model: the TSMC founder who saw that chip manufacturing could be a standalone business serving others' designs and never competing with them, a reorganization that created the fabless industry and restructured the entire semiconductor world around the separation of design from fabrication.
