SSEC Spin Motor Controller

Product Description

SSEC Solid State Equipment Spin Motor Controller – Vacuum Chamber Substrate Rotation Module

A specialized motor controller module manufactured by Solid State Equipment Corporation (SSEC), designed to precisely control substrate rotation (spinning) motors within semiconductor vacuum process chambers. This module is critical for achieving uniform thin-film deposition, etching, or coating in tools such as sputtering systems, PECVD reactors, and wafer coaters.

🔧 Key Specifications & Details:

• Manufacturer: Solid State Equipment Corporation (SSEC)

• Function: Controls brushless or stepper motors used for rotating substrate holders, planetary fixtures, or wafer carousels inside vacuum

• Typical Integration: Part of SSEC’s vacuum system control racks for cluster tools or standalone process modules

• Control Features: Likely includes speed regulation, directional control, start/stop sequencing, and interlock with vacuum/pressure states

• I/O: Interfaces with main tool controller (via RS-485, analog, or discrete I/O), connects to motor power and feedback (encoder/hall sensors)

• Connectors: Industrial multi-pin types (D-sub, circular, terminal blocks) for power, control, and motor phases

• Indicators: Status LEDs for power, fault, rotation activity, and system ready

• Environment: Designed for clean industrial use, often in 19″ rack mount configurations

🛠️ Potential Applications:

• Semiconductor Tool Repair: Direct replacement or donor board for SSEC-equipped deposition or etching systems

• Custom Vacuum System Integration: Adding substrate rotation to lab-scale sputter coaters, thermal evaporators, or research chambers

• Process Development: Prototyping uniform coating or etching systems in R&D environments

• Technical Training: Instructional tool for semiconductor equipment maintenance or vacuum technology courses

• Component Salvage: Source of high-quality motor drivers, optoisolators, power components, and industrial connectors
