Laurell
EDC-650-8
The Laurell EDC-650-8 is a station-mounted spin processor. The Laurell EDC-650-8 accommodates up to 200mm wafers. The Laurell EDC-650-8 has a 12,000 RPM capability with vacuum hold-down.[1][2][3]
What it is
How it works
The Laurell EDC-650-8B uses a process chamber with adjustable down-flow exhaust and drain, wafer alignment tools, and a vacuum hold-down arrangement for chucks.[1]
The Laurell EDC-650-8B uses a 650-series process controller that supports real-time operator interaction, downloadable firmware revisions, and optional PC-based process management.[1]
Where it fits in the process flow
The Laurell EDC-650-8B is supported for etch, develop, and clean processes, typically followed by solvent or aqueous rinse and then dry.[1]

Frequently asked questions
What types of substrates can be processed on a spin processor of this class?General reference — not yet source-verified
Spin processors can accommodate a variety of substrate shapes and sizes, including round wafers, square panels, and irregular pieces, provided they can be safely secured on the chuck. Common materials include silicon, glass, quartz, and various polymers.
What materials can be spin-coated using such equipment?General reference — not yet source-verified
The equipment is suitable for a wide range of liquid materials, such as photoresists, dielectric polymers, polyimides, adhesives, and nanoparticle suspensions. The key requirement is that the material can form a continuous film that solidifies through solvent evaporation or thermal curing.
Is the process automated or manual?General reference — not yet source-verified
Most modern spin processors offer programmable automation for dispensing sequences, spin speed profiles, and cleaning cycles. However, some may allow manual operation for research or low-volume applications. Automation ensures repeatability and reduces operator intervention.
What factors affect film thickness and uniformity in spin processing?General reference — not yet source-verified
Thickness and uniformity are influenced by spin speed, acceleration rate, spin time, ambient temperature and humidity, as well as the viscosity and volatility of the liquid material. Proper optimization of these parameters is essential for achieving consistent results.
