A Collection of Classifications to Understand Types of Domestic Semiconductor Companies

An industry map categorizing domestic semiconductor companies by their roles such as memory, foundry, fabless, equipment, materials, packaging, and testing.

The domestic semiconductor industry cannot be explained solely by large memory companies like Samsung Electronics and SK hynix. Foundry, fabless, design houses, equipment, materials, components, packaging, and testing companies together form the ecosystem. Some companies are sensitive to memory price cycles, some are affected by customer investment in facilities, and some are more closely connected to the demand for AI packaging and HBM. This list organizes classifications that help in understanding domestic semiconductor companies by their roles.

Memory Manufacturing Companies

Memory Manufacturers

The largest segment of the domestic semiconductor industry consists of memory manufacturers. DRAM and NAND are used in PCs, smartphones, servers, and data centers, while HBM is gaining attention alongside AI semiconductors. Memory companies are significantly affected by product prices and inventory cycles. When market conditions improve, profits can quickly increase, but if supply becomes excessive or customer inventories rise, performance fluctuations can grow. When evaluating memory companies, it’s essential to check HBM certification and supply, general DRAM prices, NAND profitability, and facility investment plans.

Foundry Companies

Foundry companies manufacture chips designed by fabless or system companies. In Korea, the foundry business is linked to various fields, including AI, mobile, automotive, and image sensors. The key to foundries is process technology, yield, customer trust, and long-term production capacity. Advanced processes involve significant development costs and facility investments, making it hard to achieve results in a short period. When evaluating foundry companies, it’s advisable not just to look at the process roadmap but also to check the actual mass production status of customer products, yield stabilization, and packaging capability.

Fabless Company

Fabless Companies

Fabless companies focus on chip design without manufacturing facilities. Domestic fabless companies may be smaller compared to large global firms, but they often develop specialized design capabilities in specific application areas. Demand and competition vary across fields such as AI inference chips, automotive semiconductors, power management chips, display driver chips, and communication chips. For fabless companies, strong design capabilities are vital, but securing foundry access, utilizing IP, providing software support, and customer adoption are also crucial. It may take time to transition to revenue, so one should closely observe mass production stages and customer validation.

Design House

Design Houses

Design houses assist fabless companies in ensuring that the chips they design can be produced through foundry processes. This includes design verification, physical design, process optimization, IP integration, and tape-out support. Advanced processes tend to have complex design rules, making collaboration with foundries essential; thus, the role of design houses can become more significant. For the domestic fabless ecosystem to grow, the collaboration structure between design houses and foundries must also develop together. This area may not be highly visible, but it can be viewed as a practical industry that connects design and manufacturing.

Semiconductor Equipment Company

Semiconductor Equipment Companies

Semiconductor equipment companies supply production facilities necessary for chip manufacturing. They cover various subfields such as etching, deposition, cleaning, inspection, measurement, and packaging equipment. Domestic equipment companies often have strengths in specific processes or customer companies, and they are influenced by customer investments in new fabs, process transitions, and localization trends. There can be differences between orders and deliveries, as well as perception timings for equipment companies, so it’s important to consider these time lapses when examining revenue flows. Additionally, if there are only a few customer companies, performance volatility can be significant.

Semiconductor Materials and Components Company

Semiconductor Materials and Components Companies

Materials and components companies support the stability of semiconductor processes. They include various items such as wafers, photoresists, specialty gases, slurries, cleaning agents, quartz/ceramic components, and substrates. Once materials and components enter a customer's process, they may be supplied for a long period, but obtaining certifications can take time. Quality issues can directly impact yield, making customer trust crucial. Domestic materials and components companies are often highlighted for issues related to localization and supply chain stability, but it’s essential to also consider their actual revenue scale and customer diversification.

Packaging and Post-Process Company

Packaging and Backend Process Companies

Packaging and backend process companies play a crucial role in turning chips from wafers into actual products. This includes cutting, bonding, molding, package assembly, and testing. In the past, they received relatively less attention compared to frontend processes, but with the spread of AI semiconductors, HBM, and chiplet structures, the importance of advanced packaging has significantly increased. When evaluating domestic backend process companies, checking what packaging technologies they possess, which customer demands they are exposed to among servers, AI, and mobile, and if they have capabilities in substrates and testing can be helpful.

Test Company

Testing Companies

Testing companies verify whether semiconductor products meet customer requirements. They filter out defects and verify performance and reliability through wafer testing and package testing. Products that are high in cost and require reliability, such as AI semiconductors, automotive semiconductors, and server chips, may have more stringent testing demands. Testing time and equipment utilization rates impact profitability, and performance can vary based on the customer product mix. Although testing companies will be increasingly necessary as the number of semiconductor finished products grows, one must also consider unit costs and facility investment burdens.

When looking at domestic semiconductor companies, it’s better to first check “where they are positioned” rather than just the company name. Memory companies are influenced by prices and supply, equipment companies by facility investments, materials and components companies by customer certifications and supply stability, and packaging and testing companies by downstream demand and product mix. Even within the same semiconductor theme, the timing of performance fluctuations and risks can differ. This list is for understanding the industrial structure, and individual company investment decisions should separately consider disclosures, performance, client companies, orders, and financial status.
