The Laurell EDC-650 is a spin processor, a class of equipment used for applying uniform thin films of photoresist or other liquids onto substrates by centrifugal force. The EDC-650 series is designed for solvent-based and aqueous-based processing, including etch-rinse-dry, develop-rinse-dry, and cleaning applications. The system features a zero-porosity Teflon fluid path with an onboard dispense valve manifold and a clear ECTFE domed lid for process visibility.[2]
Spin processors operate by holding a substrate on a rotating chuck, typically using vacuum hold-down, while a liquid is dispensed onto the center of the substrate. Centrifugal force spreads the liquid into a thin, uniform film. The EDC-650 series uses a digital process controller that can manage multiple dispense steps and spin speeds. The system includes a clear lid, safety interlocks, and an adjustable down-flow exhaust to control the process environment.[2]
The EDC-650-15B model is capable of 12,000 RPM with vacuum hold-down, but is recommended for operation at 3,000 RPM, especially with non-vacuum chucks. The system's 650-series controller allows real-time interaction, pausing, and process continuation. The controller can be used with PC software (Spin 3000) for remote operation and process recording, though programming can be done without a PC. The housing is typically made from a solid co-polymer blend or optionally from PTFE/Teflon for chemical resistance.[3]
The process chamber is designed with a labyrinth seal to protect the motor and electronics from chemical contamination, and a Nitrogen purge is available. The lid and internal bowl shape control liquid flow from dispense to drain, minimizing drips. The system includes a bowl-wash and dry routine that can be added to any process.[3]

The EDC-650-15B is capable of 12,000 RPM with vacuum hold-down, but is recommended for operation at 3,000 RPM, especially with non-vacuum chucks.[3]
The system has vacuum hold-down capability, but a non-vacuum chuck is always recommended for etch-rinse-dry, develop-rinse-dry, and cleaning processes. Non-vacuum chucks are available in English or metric sizes, as well as small fragment and high porosity versions for thin films.[2][3]
The fluid path is zero-porosity Teflon. The housing is typically made from a solid co-polymer blend or optionally from PTFE/Teflon (Hostaflon TFM-1600). The lid is made of clear ECTFE, and non-wetted areas use ECTFE-coated 316 stainless steel screws.[2][3]
The 650-series controller can be used with a PC running Laurell's Spin 3000 software for remote operation, process recording, and LAN/Internet communication. However, the equipment can be programmed and run without a PC, using the onboard controller.[3]
