TESTEQ Thermal Vacuum Cleaning System for High-Precision Semiconductor Components
Industry-Leading Contamination Removal for Lithography, Optics & Wafer Processing
This equipment adopts an innovative inclined sealing structure (patented design-Thermal Vacuum/Lithography/UHV).
Through the gravity-adaptive cover plate and double-ring sealing ring interlocking technology, it can maintain a stable vacuum level (≤10⁻⁶ Pa), solving the problem of reduced cleaning efficiency caused by sealing failure in traditional equipment.
It integrates a dual-fluid spray system (sodium hydroxide + deionized water), supporting non-destructive cleaning in a high-temperature (350℃) vacuum environment, avoiding thermal stress deformation.
It is suitable for the maintenance of high-precision components such as mask plates, lens groups, and vacuum pump components of lithography machines, significantly improving chip yield and equipment lifespan.
A fully automatic thermal vacuum cleaning equipment specially designed for components of lithography machines and mask plates. Through a high-temperature and low-pressure environment and non-contact dry cleaning technology, it can thoroughly remove nano-level contaminants (such as organic residues and particles), meeting the strict requirements for ultra-clean surfaces in semiconductor manufacturing, flat panel display, and integrated circuit fields. It supports multi-scenario cleaning of wafers, optical lenses, vacuum chambers, etc.
