Lam Research builds the machines that carve, coat and clean the thin silicon discs from which computer chips are made. Etching is the largest engine, while a substantial support business turns every installed machine into repeat demand for parts, upgrades and care. The company is leaning into more intricate memory and chip-packaging work, but its fortunes remain tied to a small group of giant chipmakers and rules governing where advanced equipment may be shipped.

Etch
Lam's biggest machine family carves the tiny channels and spaces that make modern chips work. The number of Akara machines in customer factories had doubled each year through July 2026; continued adoption is the key test.
Competes with Centris Sym3 Z Magnum (Applied Materials) · Tactras (Tokyo Electron)
In plain English
A computer chip begins as a thin silicon disc. Lam's etch machines use carefully controlled gas and electrical energy to remove selected material, carving microscopic paths through layer after layer. More elaborate chips require more carving steps, so complexity can matter as much as the number of discs factories process.
Chipmakers pay for each large machine and qualify it for a specific factory job, making a proven tool difficult to replace. Lam names Micron, Samsung, SK hynix and TSMC as significant buyers; four customers together supplied 55% of sales, without Lam matching names to individual shares.
Advanced Packaging
These tools carve, coat and clean the connections that join separate chips into one package. Management said sales in calendar 2026 were growing more than 70% from a smaller base; production take-up must follow development work.
Competes with Kinex hybrid bonding system (Applied Materials / Besi) · Synapse / Ulucus (Tokyo Electron)
In plain English
Once separate chips are made, they need short, fast connections to work together. Lam supplies machines that drill tiny vertical paths, fill them with metal, add insulating layers and wash away residue—jobs used to stack memory or place several chips side by side.
Contract chip factories and memory makers buy those machines as their package designs move from experiments into volume production. Lam has already shipped large square-panel systems to development programs, but the buyers are unnamed. Packaging money arrives through the carving, coating and cleaning machines used for these jobs, rather than through a separate checkout line.
Customer Support Business Group
Sales from parts, repairs, upgrades and factory-help services grew 20.2% in FY2026. Watch how heavily customers run their factories: quieter machines need fewer parts and less attention.
Competes with Applied Global Services (Applied Materials) · Engineering Services / TELeMetrics (Tokyo Electron)
In plain English
The unglamorous part that keeps the installed fleet earning. Each Lam machine contains sealed work areas called chambers; across customers, the fleet has roughly one hundred thousand of them. Lam sells replacement parts, technician visits, performance software, upgrades and additional systems for older chip factories.
It works like maintaining a huge fleet of delivery trucks: the more vehicles on the road and the harder they run, the more maintenance they need. Customers keep paying because downtime is costly and upgrades can squeeze more output from scarce factory space. When factories slow, however, this repeat business slows too.
Deposition
These machines lay down the conducting and insulating films from which a chip's stacked structure is built. Demand rises as chipmakers add more layers and introduce new materials; successful factory testing decides who gets paid.
Competes with Producer CVD (Applied Materials) · Eagle XP8 PEALD (ASM International)
In plain English
No advanced chip is made from a single slab. It is built from many extremely thin layers, some carrying electricity and others keeping signals apart. Lam's deposition machines lay those films onto silicon discs evenly, including metals used for tiny connections and insulating material that fills narrow gaps.
Chipmakers buy a machine after proving that its coating is uniform enough for a particular step. Think of applying dozens of flawless coats of paint, except a speck or uneven edge can spoil the finished piece. Taller memory stacks and more complicated structures create additional coating jobs, while material supply and factory testing govern how quickly a tool wins them.
Strip & Clean
A smaller tool line removes leftover light-sensitive coating, particles and chemical residue between manufacturing steps. Each added layer creates another chance for contamination, but near-term demand still follows factory activity.
Competes with CELLESTA (Tokyo Electron) · SU-3400 (SCREEN Semiconductor Solutions)
In plain English
Dust that would be harmless on a kitchen table can ruin a microscopic circuit. Between chipmaking steps, Lam's machines use liquids or electrically charged gas to strip away used coating, loose particles and residue, then prepare the silicon disc for whatever comes next. Some clean the flat surface; Coronus works around the outer edge.
Factories pay for dedicated cleaners because defects destroy valuable work already completed on a disc. The business grows when three-dimensional chips require more repeated steps, since more steps mean more cleaning. Sales can still swing with the number of discs moving through factories and with each machine's speed and cleaning quality.
Aether
Aether applies and develops a dry, metal-based light-sensitive coating for printing extremely small chip patterns. Lam once targeted about $1.5 billion of cumulative five-year revenue, but today's base remains small and later mentions have been sparse.
Competes with CLEAN TRACK LITHIUS Pro DICE (Tokyo Electron) · Inpria metal-oxide resist (JSR / Inpria)
In plain English
Instead of spreading a wet light-sensitive coating, Aether puts down a dry metal-based film. A very short-wavelength light beam then prints a pattern into that film, and the machine develops it for later carving. The aim is to use less light and remove some manufacturing steps.
An unnamed memory maker chose Aether as its standard production machine for advanced memory, giving the platform an important first foothold. That customer and future adopters pay for systems as each tightly controlled factory job is approved. Adoption still depends on costly light-producing machines, lower processing cost and proof that the method avoids tiny flaws.
