High-Throughput 24-Position Automatic Spin Coating System – For Wafer, Glass, OLED Substrates – Customizable Dispensing
Product Overview
The 24-Station Spin Coater is a high-throughput thin-film coating system designed for uniform deposition of photoresist, polymers, sol-gel, and nanoparticles onto wafers, glass substrates, or discs. Each station can be independently programmed or run in batch mode.
The machine is fully customizable - station arrangement, spin speed profiles, dispensing method, bowl material, and exhaust design - to suit R&D, pilot line, or production environments.

Frequently Asked Questions
Q: Can all 24 stations run simultaneously at different speeds?
A: Yes and no - In independent motor version (higher cost), yes. In shared-drive version, all run same speed but can have different dispense timing - customizable to your need.
Q: What is the minimum substrate size the chuck can hold?
A: Standard chucks hold 2″ to 8″. For smaller pieces (1 cm × 1 cm), we can customize vacuum chucks with reduced vacuum zones.
Q: Can I use this coater for high-viscosity materials (like SU-8 or thick photoresist)?
A: Yes. We can customize the motor torque and dispense nozzle (larger gauge) for high-viscosity applications.
