Wafer Process

Exceptional Chemical Inertness: Fabricated from 100% high-purity PTFE, providing total resistance to concentrated HF, H2SO4, and BOE (Buffered Oxide Etch). Optimized Fluid Dynamics: Engineered with precision-milled slots and an open-frame design to ensure maximum chemical circulation and uniform rinsing. Surface Protection: The ultra-smooth, non-stick PTFE surface prevents wafer scratching and minimizes particle adhesion during processing. Thermal Stability: Maintains structural integrity in high-temperature chemical baths up to 250°C. Bespoke Customization: Fully tailorable slot pitch, pocket depth, and overall dimensions to accommodate any wafer size (2", 4", 6", 8") or non-standard substrate.

Chemical-Inert Armor: Fabricated from 100% high-purity PTFE, providing total resistance to aggressive lithography chemicals, including Piranha etch (H2SO4/H2O2), developers, and organic solvents. Precision-Slotted Design: Features CNC-machined grooves that secure masks by the edges, ensuring zero contact with the critical patterned surface. Maximized Fluid Dynamics: The open-frame architecture allows for high-velocity chemical flow and rapid, bubble-free rinsing across the entire mask face. Superior Surface Finish: The ultra-smooth, non-stick PTFE surface prevents particle entrapment and eliminates the risk of scratching sensitive quartz or glass substrates. Fully Customizable Architecture: Slot pitch, pocket depth, and overall dimensions can be bespoke-tailored to fit any mask size.
