Technology & Products
Key Products
Single crystal LaB6 (lanthanum hexaboride) electron sources; Thermal field emission (Schottky) electron sources (models 174C, 174J, M20); Scandium-containing high-emission electron sources
Technological Advantage
CLAIMED: Proprietary 'Novel Process' for high-purity monocrystal lanthanum growth. VERIFIED: Recognized as China's first high-tech enterprise in this specialized material segment, a critical position for domestic import substitution. DEFENSIBLE: High technical barriers associated with single-crystal growth and $19.3M in funding create significant capital and expertise moats against domestic entrants.
Differentiation
Value Proposition
Domestic high-brightness, long-life electron sources replacing imported cathodes (e.g. Denka Schottky, AP-TECH LaB6) for SEM, chip e-beam inspection, EBM, and e-beam lithography.
How They Differentiate
Specialized Chinese supplier of electron sources/cathodes for SEM, semiconductor e-beam inspection, EBM, and e-beam lithography. Performance: mono-crystal LaB6 (high brightness/long life vs tungsten); Schottky sources targeting 8000+ h life and ~1.21 nm@30 kV SEM resolution (Denka-class). Cost: domestic price advantage vs Kimball Physics and Denka. Range: microtip-to-planar LaB6 (Φ0.01–3 mm), Schottky (Φ0.6–4 μm), proprietary Sc-containing high-emission cathodes for lithography. Not a polymer extruder or filament equipment maker—prior text mixed in unrelated extrusion/PEEK/PLA content.
