Semiconductor Companies Explained: Designers, Foundries, Memory and Equipment

The company designing a processor need not own the factory that produces it. The factory, in turn, depends on equipment suppliers whose customers make investment decisions years before the finished chip reaches a server or a car.

That division of labour explains why semiconductor companies can respond differently to the same demand cycle. More spending on AI systems can raise orders for processors, memory and networking, but the revenue reaches each supplier on a different timetable.

This is a guide to those business models, not a size ranking. For a dated comparison of equity values, use GMR’s semiconductor market-cap ranking.

Fabless designers: product economics without owning every factory

Nvidia, AMD and Qualcomm are examples of companies that design chips while relying on external manufacturing. Their competitive position depends on architecture, software, customer relationships and the ability to bring products to market.

Contracting out fabrication avoids the need to finance the entire factory network. It does not remove supply risk. A design still needs access to manufacturing capacity, packaging, testing and components at the right cost and quality.

For analysis, start with the end market. Data-centre accelerators, smartphone processors and automotive chips serve different customers with different replacement cycles. A strong quarter in one category does not establish a broad recovery across all chip demand.

Foundries and integrated manufacturers

TSMC describes itself as a dedicated semiconductor foundry: it manufactures customers’ designs rather than selling branded end-market chips that compete with those customers. Its economics depend on manufacturing technology, yields, utilisation and the cost of maintaining capacity.

Integrated device manufacturers combine design and manufacturing. Texas Instruments, for example, designs and manufactures analogue and embedded-processing products. Intel operates product businesses as well as a foundry business. These models require separate analysis of product competitiveness and factory economics.

A new fabrication plant can take years to build and equip. The resulting fixed costs make utilisation important: the revenue earned at a busy factory can look very different from the economics of a plant running below capacity.

Memory: storage, working memory and changing supply

Micron, Samsung Electronics and SK hynix are prominent memory producers. DRAM provides working memory, while NAND flash supports persistent storage. High-bandwidth memory is a specialised form of DRAM used alongside demanding processors, including AI accelerators.

Memory analysis needs both product mix and industry supply. Higher demand does not guarantee stronger margins if capacity expands too quickly. Conversely, a change in supply discipline can improve pricing before unit demand accelerates.

Comparisons should distinguish the memory business from the whole group. Samsung Electronics has substantial activities outside semiconductors, so its consolidated financial results and stock-market value are not a pure measure of memory demand.

Equipment suppliers sell into manufacturers’ budgets

ASML supplies lithography systems used to pattern chips. Applied Materials and Lam Research provide equipment for other fabrication steps, while KLA supplies process-control and inspection systems. Their customers need many different technologies to turn a design into usable chips.

These suppliers depend on factory spending, technology transitions and servicing the installed equipment base. Chip demand matters, but the immediate sales decision is often a manufacturer’s equipment budget.

That creates timing differences. An equipment order may arrive before a factory contributes much chip revenue; a delayed factory project can affect suppliers even while demand for finished devices remains healthy.

IP licensing adds another business model

Arm licenses processor technology and earns royalties associated with products using its intellectual property. Licensing differs from selling a finished chip or operating a foundry. Adoption, contractual terms and royalty-bearing shipments matter alongside demand for computing.

The categories are useful starting points, not rigid boxes. Broadcom combines semiconductor operations with infrastructure software, and several manufacturers use both internal and external production.

Before comparing valuations, establish what each company sells, who pays for it and how much investment is needed to grow. GMR’s Nvidia, TSMC, ASML and Arm stock profiles connect those business models with company coverage.
