What Kurt J. Lesker Company does

Kurt J. Lesker Company (KJLC) is a privately held, woman-owned manufacturer and global distributor of vacuum products and thin film deposition systems, founded in 1954 and headquartered at 1925 Route 51, Jefferson Hills, Pennsylvania. The company operates through four specialized divisions — Vacuum Mart (14,000+ standard vacuum components), Process Equipment (PVD, ALD, and evaporation systems plus TORUS magnetron sputtering cathodes and the OCTOS cluster tool), Materials (sputtering targets, evaporation materials, and target bonding with precious-metal reclaim), and Manufacturing (custom vacuum chambers via Chamber Builder and Nipple Builder). It maintains wholly-owned subsidiaries in the UK, Germany, Canada, and China to support regional direct sales across the Americas, EMEIA, and Asia.

The company's technology stack spans bench-top PVD systems (PVD 75), research-grade evaporation systems (SPECTROS 100), ALD platforms (ALD150LX, ALD150LE), precision substrate stages (EpiCentre, MultiCentre), and proprietary digital configurators (Chamber Builder, Nipple Builder, VacuCAD 2D/3D CAD service). Its 2026 peer-reviewed publication in Nature's Communications Materials on ferroelectric AlScN deposited by plasma-enhanced ALD under ultrahigh-purity conditions evidences advanced R&D capability at the leading edge of next-generation semiconductor materials.

KJLC runs a quote-based, direct-sales go-to-market with regional field sales, phone support, e-commerce storefront, and custom-configuration tools. Revenue is generated primarily through hardware sales across vacuum components, deposition equipment, and materials, supplemented by service and repair (pump repair, TORUS services, target bonding, precious metal reclaim) and training (Lesker U Live webinars, Vacuum Training System). End markets span semiconductor/electronics, medical devices, photovoltaics, R&D (including quantum/superconductor), displays, aerospace, data storage, optical, sensors, coatings/extrusion, and organic electronics. The company is led by Kurt J. Lesker IV as President & CEO and holds ISO 9001, ISO 14001, ISO 45001, OSHA SHARP, and EU WEEE certifications across its manufacturing and sales footprint.
