What is materials engineering in semiconductor manufacturing?

Traditional chip scaling (Moore's Law) shrinks transistors to pack more onto a chip. But below approximately 5nm, physical limits make further scaling increasingly difficult — quantum tunneling, thermal leakage, and manufacturing variability become limiting factors. Materials engineering addresses this by introducing new materials that improve performance at existing or larger sizes: new metals for contacts and interconnects with lower resistance (cobalt, ruthenium replacing copper/tungsten), new dielectrics with better electrical properties, 2D materials (MoS2, graphene) for ultra-thin channel transistors, and new ferroelectrics for memory. Applied Materials' thesis is that as geometric scaling slows, materials innovation becomes the primary driver of semiconductor improvement.

What is the 'process control intensity' debate in semiconductor equipment?

Process control intensity refers to the percentage of total wafer fabrication equipment spending that goes to inspection and metrology tools versus process equipment (deposition, etch, lithography). Historically this has been around 10-12% of WFE. KLA and its investors argue that increasing chip complexity will raise process control intensity — more defect sources and tighter tolerances mean chipmakers must inspect more frequently. If process control intensity rises to 13-14%, it would be a significant revenue tailwind for KLA above and beyond the overall WFE market growth. Skeptics argue chipmakers will resist higher inspection costs by using AI-based defect prediction to reduce physical inspection steps.

How do KLA's margins compare to the rest of the semiconductor equipment industry?

KLA consistently achieves gross margins around 58-62% — among the highest in the semiconductor equipment industry. For comparison, Applied Materials typically achieves 47-50% gross margins, Lam Research around 45-48%, and ASML around 50-55%. KLA's higher margins reflect its dominant market position in wafer inspection — as the only supplier capable of meeting leading-edge fabs' performance requirements, KLA can price its equipment based on the value it provides (avoiding costly yield excursions) rather than competitive price pressure. This pricing power, combined with high-margin service revenue from its inspection equipment installed base, sustains KLA's industry-leading margins.

Business comparison

Category	KLAC	AMAT
Company	KLA Corporation	Applied Materials, Inc.
Sector	Technology	Technology
Industry	Semiconductor Equipment & Materials	Semiconductor Equipment & Materials
Core business	KLA Corporation is the world's dominant provider of semiconductor process control equipment — inspection systems that detect defects on wafer surfaces, metrology systems that measure critical dimensions and film properties, and wafer-level data analytics. KLA's equipment is used after nearly every process step to verify that the previous step was performed correctly before proceeding.	Applied Materials is the world's largest semiconductor equipment company — providing materials deposition (CVD, PVD, ALD), etch, ion implant, thermal processing, and process control equipment for logic, memory, and display manufacturing. Applied Materials participates in more wafer fabrication steps than any other equipment company.
Investor focus	Investors track KLA's equipment orders, process control intensity (the share of fab spending on inspection/metrology versus deposition/etch), service revenue from its inspection equipment installed base, and China exposure under export restrictions. KLA is valued for its dominant ~50% market share in wafer inspection and high gross margins.	Investors track Applied Materials' bookings across its materials engineering, etch, and process control segments, service revenue growth, China export restriction impact on revenue, and the company's materials engineering narrative as new materials enable performance gains at each node when transistor scaling faces limits.

KLAC strengths

→Near-monopoly in wafer inspection — KLA has approximately 50% market share in wafer defect inspection, with the next competitor (Applied Materials' inspection unit) far behind. This near-monopoly reflects decades of instrument performance investment that makes competitors' products insufficient for leading-edge fabs
→Process control intensity increases with each node — more complex chips create more potential failure modes, requiring more inspection and metrology steps. KLA's content per wafer grows with complexity independent of volume
→Highest gross margins in semiconductor equipment (~60%) — KLA's process control monopoly position supports premium pricing impossible in more competitive equipment categories

AMAT strengths

→Revenue and product diversification across more process steps than any competitor — Applied Materials' exposure to CVD, PVD, ALD, etch, ion implant, and inspection reduces single-process concentration risk
→Materials engineering thesis — as traditional transistor size scaling slows, new materials (cobalt contacts, ruthenium interconnects, 2D materials) enable continued performance improvement, and Applied Materials is positioned as the leader in depositing and engineering these advanced materials
→Scale and customer relationships spanning every major logic, memory, and foundry manufacturer globally creates a formidable customer network that reinforces Applied Materials' ecosystem position

Risks to watch — KLAC

→Single-market concentration — KLA is more narrowly focused on inspection/metrology than Applied Materials' diversified portfolio; a slowdown in process control spending or breakthrough by competitors would have outsized impact
→China export restrictions — KLA's inspection and metrology equipment for advanced nodes is subject to U.S. export controls; China revenues represent a significant portion of historical sales
→Very high market share means limited upside from share gains; growth depends on industry capex levels and process control intensity increasing with each node

Risks to watch — AMAT

→Lower market share in any single equipment category versus specialists — KLA in inspection/metrology, Lam in etch, ASML in lithography each have stronger individual positions than Applied Materials in their respective niches
→Breadth creates organizational complexity — Applied Materials manages dozens of different product lines across multiple semiconductor process steps, which can diffuse engineering focus versus more specialized competitors
→China exposure to export restrictions is significant given the large China revenue base that has been constrained by U.S. export controls

Frequently asked questions

Wafer inspection uses optical or electron-beam systems to scan wafer surfaces and detect defects — particles, pattern defects, scratches, or process variations that deviate from specifications. After identifying defects, metrology tools measure critical dimensions (did the etch go to the right depth? is the film the correct thickness?) to verify process accuracy. KLA has invested for 50+ years building inspection systems with the optical performance, throughput, and sensitivity needed to detect nanometer-scale defects on wafers 300mm across. Competing at this performance level requires extraordinary capital investment in optical systems, algorithms, and calibration — creating enormous barriers to entry that have given KLA its dominant market share.
