3 Chip Stocks Set to Win TSMC’s Packaging Boom

• TSMC is expanding advanced-packaging capacity as demand from Nvidia and other chip designers continues to rise.
• KLA, Camtek, and Nova sell different types of inspection and metrology equipment used to protect manufacturing yields.
• KLA offers the broadest exposure, while Camtek and Nova provide greater leverage to specialized packaging applications.

Taiwan broke ground on a new advanced-packaging industrial park on September 21, with Taiwan Semiconductor Manufacturing Co. (NYSE: TSM) serving as its principal technology anchor. The project will include facilities where equipment and materials suppliers can test and validate technologies used in advanced packaging before they enter mass production.

For investors, the more important question is not whether TSMC will remain the dominant producer of advanced AI processors. It is which equipment companies benefit as TSMC and its customers increase the number, size, and complexity of the packages they manufacture.

Three companies stand out: KLA Corporation (NASDAQ: KLAC), Camtek Ltd. (NASDAQ: CAMT), and Nova Ltd. (NASDAQ: NVMI). All three sell process-control equipment, but each addresses a different part of the manufacturing problem. KLA provides the broadest inspection platform, Camtek is the most directly exposed to advanced-packaging inspection, and Nova supplies specialized dimensional, materials, and chemical metrology.

Packaging Demand Creates the Equipment Opportunity

Advanced packaging connects a high-performance processor with high-bandwidth memory and other components inside one integrated package. As more dies and connections are added, the financial cost of a defect increases. A defective component discovered late in production can result in the loss of several expensive dies rather than one unfinished chip.

This changes the economics of inspection. Semiconductor manufacturers cannot expand packaging output simply by installing more production equipment. They must also add inspection and metrology capacity to identify defects, verify alignment, measure critical dimensions, and control material composition. Higher packaging volume therefore creates demand for the equipment sold by KLA, Camtek, and Nova.

The equipment opportunity can grow faster than the number of packages produced because each new generation introduces additional points that must be inspected. A conventional chip is largely tested as a single device. An advanced package can combine a processor, several memory stacks, interposers, substrates, and thousands of microscopic connections. Inspection may be required before bonding, during assembly, and after the package is completed. The larger number of control points increases equipment demand even if the number of finished packages grows at a slower rate.

Yield also becomes more important as component values rise. If a low-cost chip is found defective near the end of production, the manufacturer loses one device. If a fault is discovered after an advanced processor and multiple HBM stacks have been combined, the loss can include several high-value components and the packaging work already performed. That makes process-control spending a form of economic protection. Manufacturers can postpone some capacity investments, but reducing inspection when package values are increasing can create a much larger financial loss.

According to Table 1, Nvidia-driven CoWoS demand is projected to increase from 360,000 wafers in 2024 to 810,000 in 2027. The forecast represents a 125% increase in three years. The largest annual increase occurs in 2026, when demand is expected to rise 40% to 678,000 wafers as Blackwell Ultra and Rubin CPX production increases.

The table is important because every additional CoWoS wafer must move through multiple inspection and measurement steps. The opportunity is not limited to Nvidia. Advanced Micro Devices (NASDAQ: AMD), Broadcom (NASDAQ: AVGO), and other designers also rely on TSMC’s packaging technologies for high-performance processors. Nvidia remains the largest demand driver, but the equipment investment is supported by a broader move toward multi-die designs.

The projected increase from 360,000 CoWoS wafers in 2024 to 810,000 in 2027 therefore understates the potential increase in inspection activity. New package generations are not merely increasing unit volume. They are becoming larger and more difficult to manufacture, requiring more measurements per package and tighter tolerances at each production step. This combination of higher volume and greater inspection intensity is what supports the revenue outlook for all three equipment companies.

KLA Offers the Broadest Exposure

KLA is the largest and most diversified of the three companies. Its systems inspect patterned wafers and reticles, measure critical dimensions and overlay, analyze defects, and inspect packages, substrates, printed circuit boards, and electronic components. It can benefit before a processor reaches the packaging stage and again when that processor is integrated with memory and other dies.

KLA reported fiscal fourth-quarter 2026 revenue of $3.66 billion, an increase of 15.2% from the prior year. Full-year revenue reached $13.58 billion, while free cash flow totaled $3.77 billion. Management guided to approximately $4.0 billion in revenue at the midpoint for the September quarter, representing an additional sequential increase of about 9%.

KLA’s main advantage is its breadth. Its results do not depend on one customer, one packaging format, or one part of the semiconductor market. The company benefits from leading-edge logic, DRAM, high-bandwidth memory, reticle inspection, and advanced packaging. That diversification makes KLA the strongest core holding of the three, although its larger size means it will not grow as rapidly as a smaller supplier during a packaging-capacity surge.

KLA also benefits after its systems are installed. Inspection tools operate in production environments where uptime and measurement consistency are critical, creating continuing demand for service, maintenance, software, and replacement parts. As customers install more tools, KLA expands an installed base that can produce recurring revenue beyond the original equipment sale. This reduces some of the volatility normally associated with semiconductor capital equipment and gives KLA a second way to benefit from packaging expansion.

The limitation is that advanced packaging represents only one part of a much larger company. A major increase in packaging-related sales can materially improve Camtek’s results because of its smaller revenue base, while the same dollar increase has less effect on KLA’s consolidated growth. Investors choosing KLA are therefore emphasizing competitive strength, cash generation, and diversification rather than the highest possible sensitivity to the packaging cycle.

Camtek Has the Greatest Packaging Leverage

Camtek provides the most direct exposure to advanced-packaging inspection. Approximately 75% of its second-quarter revenue came from advanced packaging, and management expects that proportion to approach 80% by the end of 2026.

The company reported second-quarter revenue of $133.2 million, increasing 10% sequentially and 8% from the prior year. Its third-quarter guidance of $158 million to $160 million implies approximately 20% sequential growth at the midpoint. Camtek also received more than $600 million in orders during the first seven months of 2026, with deliveries extending into 2027.

Camtek’s Eagle G5 and Hawk platforms inspect wafers, dies, interconnects, and other structures used in high-volume packaging. The company is also expanding into backside inspection, hybrid bonding, residue detection, and additional metrology applications. Its acquisition of Visual Layer adds software for image analysis and defect classification, which can improve inspection speed and reduce false alarms.

Camtek has the strongest near-term growth profile, but it also carries the greatest concentration risk. If advanced-packaging equipment orders slow or customers postpone capacity additions, Camtek has less diversification than KLA. Investors are therefore receiving greater growth potential in exchange for greater sensitivity to the packaging cycle.

The company’s order intake provides unusual visibility for a business of Camtek’s size. More than $600 million of orders received through the first seven months of 2026 exceeds a full year of revenue at its recent quarterly run rate. Because deliveries extend into 2027, Camtek enters the next year with a larger portion of expected demand already identified. The backlog does not eliminate execution risk, but it reduces dependence on orders that have not yet been placed.

Camtek must still convert those orders into shipments while maintaining gross margins and supporting a larger installed base. A rapid production ramp can pressure manufacturing, field service, and working capital. Customers may also alter delivery schedules even when the underlying projects remain active. These risks do not weaken the long-term packaging thesis, but they help explain why Camtek’s shares can be more volatile than KLA’s when investors question the timing of semiconductor capital spending.

Nova Extends Beyond Visible Defect Inspection

Nova occupies a different position. Its systems measure dimensions, film thickness, material composition, and chemical properties throughout semiconductor manufacturing. These measurements become more important as chip structures become smaller vertically and more complex in three dimensions.

Nova reported record second-quarter revenue of $255.0 million, increasing 16% year over year and 8% sequentially. Management guided to third-quarter revenue of $277 million to $287 million, which implies sequential growth of approximately 11% at the midpoint.

The company reported record revenue from advanced logic, advanced packaging, front-end chemical metrology, and its Sentronics dimensional-metrology systems. This gives Nova exposure to packaging growth without making the company entirely dependent on it. Nova also benefits from gate-all-around transistors, advanced DRAM, and new materials used in leading-edge semiconductor production.

Nova’s investment case rests on market-share gains and the expansion of its technology into additional process steps. It is less diversified than KLA but broader than Camtek’s packaging-heavy revenue mix. That makes Nova the middle choice for investors seeking above-market growth with less direct dependence on a single equipment segment.

The distinction between inspection and metrology is important to Nova’s positioning. Inspection determines whether a defect or abnormality is present. Metrology determines whether a structure, film, or material is within the precise limits required for the process to work. As manufacturing tolerances narrow, a structure can appear free of visible defects and still fail because its dimensions or material composition are outside specification. Nova’s tools address that second problem.

This gives Nova opportunities in both package assembly and the fabrication of the chips that enter the package. More advanced processors and memory devices require additional measurement steps before they reach TSMC’s packaging lines. Nova can therefore benefit from the same demand cycle at multiple production stages, although it lacks the broad inspection portfolio and installed-base scale that distinguish KLA.

What Investors Should Watch

TSMC’s packaging expansion provides the demand foundation, but the three equipment companies offer different ways to invest in it. KLA has the strongest market position and the broadest protection against a slowdown in any one segment. Camtek has the greatest direct leverage to rising packaging capacity and the strongest near-term revenue acceleration. Nova combines packaging exposure with dimensional, materials, and chemical metrology used elsewhere in advanced chip manufacturing.

For a core semiconductor-equipment position, KLA remains the most defensible choice. Camtek offers the greatest upside if current packaging orders translate into revenue through 2027, while Nova offers a more balanced growth alternative supported by share gains across several measurement categories.

Investors should monitor three different indicators. For KLA, the key question is whether rising process-control intensity continues to outpace overall wafer-fabrication-equipment growth. For Camtek, order conversion and the advanced-packaging percentage of revenue will show whether the current acceleration is durable. For Nova, continued share gains and adoption of new materials and chemical-metrology products will determine whether growth remains broader than the industry’s capital-spending cycle.

The common thesis is straightforward. As TSMC produces more complex packages for Nvidia and other chip designers, manufacturers must inspect more surfaces, measure more structures, and control more process steps. KLA, Camtek, and Nova sell the equipment required to accomplish those tasks, allowing investors to participate in the packaging expansion without relying exclusively on TSMC or a single processor company.
