INDUSTRIAL SINGLE-STATION SPIN COATER WITH ±1% UNIFORMITY – CUSTOMIZABLE ACCELERATION & DISPENSE CONTROL

INDUSTRIAL SINGLE-STATION SPIN COATER WITH ±1% UNIFORMITY – CUSTOMIZABLE ACCELERATION & DISPENSE CONTROL

Product Description

This single-station spin coater is designed for precise and uniform deposition of photoresist, polymers, sol-gel materials, nanoparticles, and other functional liquids onto substrates ranging from small fragments to 8-inch wafers. The system uses a high-stability brushless DC motor with programmable speed and acceleration profiles, ensuring repeatable thin-film coating results. Ideal for semiconductor R&D, MEMS fabrication, perovskite solar cells, and optical coating applications. The system is fully customizable in chuck size, bowl material, motor specifications, and optional heating or UV curing modules.

FAQ

Q1: Can you customize the chuck for a non-standard square substrate (100mm x 100mm)?
A: Yes. We fully customize any chuck shape and size, including square, rectangular, and irregular fragments up to 450mm.

Q2: What is the minimum and maximum coating thickness achievable?
A: Typically 0.1µm to 200µm depending on material viscosity and spin speed. We can customize spin profiles to optimize thickness for your specific coating material.

Q3: Does this spin coater work with high-viscosity materials like thick photoresist?
A: Yes. The servo motor option provides higher torque for thick materials. We can also customize the dispense nozzle and pre-spin delay.
