$LRCX

🇺🇸

Leading semiconductor equipment company specializing in etch, deposition, and clean technologies for chip fabrication. ~$17B annual revenue company with dominant market share in plasma etch systems critical for advanced chip patterning. Benefits from increasing process complexity in AI chip manufacturing and growing demand for 3D NAND memory and advanced logic nodes.

Company Profile

Equipment

The etch specialist — dominates the critical chip carving process that gets harder with every new node.

Key Products & Platforms

Kiyo

Conductor Etch

Precision etching of metal and polysilicon

Flex

Dielectric Etch

Etching insulator layers on chips

SABRE

Electroplating

Copper and metal deposition

ALTUS

Thin Film Deposition

Atomic layer deposition (ALD) tools

Coronus

Bevel Etch

Edge cleaning for wafer yield improvement

Key Customers

TSMCSamsungIntelSK HynixMicron

Competitive Position

Market Share

#1 in plasma etch (~45%), #2 in deposition after Applied Materials

Competitive Moat

Dominant etch market share; etch complexity increases with each node (more steps = more tools sold)

Key Risk

Similar to AMAT — China restrictions, cyclical capex spending

Why This Company Matters

Etch is the process of carving patterns into chips, and it gets exponentially harder at smaller nodes. As chips shrink, the number of etch steps per wafer explodes — which means Lam sells more tools per fab. AI's demand for advanced chips is a structural tailwind for Lam.

Key Milestones

Aug 1980
Milestone

Founded by David K. Lam in Fremont, CA to commercialize plasma-based etch tools; the AutoEtch 480 released in 1982 became the industry's first dry-etch system, displacing wet chemistry.

May 1984
Milestone

IPO on NASDAQ; capital funded R&D for the Rainbow polysilicon etch system, which displaced wet chemistry on key transistor-gate steps.

Sep 1997
Milestone

Acquired OnTrak Systems for M, adding chemical-mechanical planarization (CMP) tools; the platform later evolved into industry-leading copper barrier-seed deposition.

Jan 2004
Milestone

James Bagley named chairman; reorganized strategy around dielectric and conductor etch leadership, doubling down on the 90nm and 65nm logic ramps.

Dec 2004
Milestone

Acquired Bullen Semiconductor for $30M, adding key etch IP for advanced shallow-trench-isolation processes that became standard on 90nm-and-below logic.

Mar 2008
Milestone

Acquired SEZ Group for M, gaining single-wafer wet-clean tools; Lam Clean platform became standard at every leading-edge fab through 28nm and below.

Jun 2012
Milestone

Closed .4B all-stock acquisition of Novellus Systems, adding metal deposition (PVD/CVD) and wafer-clean lines; created today’s integrated etch+deposition Lam Research.

Nov 2015
Milestone

Announced $10.6B all-stock merger with KLA-Tencor; deal would have created an etch+metrology powerhouse but was abandoned in October 2016 amid antitrust resistance from regulators.

Dec 2015
Launch

Began shipping ALTUS dielectric atomic layer deposition systems for 3D NAND vertical-channel layers; the equipment became central to every 3D NAND ramp from V-NAND to 232+ layers.

Aug 2018
Launch

Released Sense.i etch productivity platform with on-board AI for real-time process control; first major equipment line to use machine learning for chamber-matching.

Oct 2022
Regulatory

Pulled engineers from Chinese fabs and cut FY2023 revenue guide by $2-2.5B due to October 7 BIS controls; pivoted resources toward HBM-related etch/deposition equipment for memory makers.

Aug 2024
Partnership

Signed strategic technology pact with IBM and SK Hynix to scale dry-resist EUV photoresist for HBM and logic; technology promised lower defectivity and higher throughput than wet resist.

Dec 2024
Regulatory

Flagged additional China shipment halts (Hua Hong, others) under December 2 BIS expansion of equipment controls; pivoted to HBM bonding tools and 3D NAND retrofits to offset China loss.

Feb 2025
Paused

Flagged $700M+ FY revenue risk from China export controls; pivoted aggressively into HBM bonding and 3D NAND tools, with HBM-related equipment up 3x YoY.

Aug 2025
Commercial

Disclosed record HBM-related equipment bookings as TSV/bonding capacity ramped at SK Hynix and Micron; HBM-related revenue topped $1B/quarter for the first time.
