Introduction

The relentless miniaturization of semiconductor devices pushes the boundaries of technology. At the heart of this process lies a hidden hero – the slip rings and rotary unions duo. These seemingly simple devices play a critical role in ensuring precise and efficient chip production by enabling uninterrupted transmission of power, data, and gases within equipment with rotating components.

Facilitating Continuous Rotation and Cleanliness

Traditional wiring methods for semiconductor manufacturing equipment, like steppers and etchers, become entangled and restrict movement during operations. This limitation can cause contamination and hinder yield rates. 

Slip rings and rotary unions offer a solution! Slip rings transfer electrical signals and control data, while rotary unions handle ultra-clean process gases – all while a component rotates freely. This ensures uninterrupted operation and maintains an ideal environment for delicate chip fabrication.

Diverse Applications in Chip Fabrication

The benefits of slip rings and rotary unions extend across various semiconductor manufacturing processes:

• Steppers: Facilitate continuous power, data, and cooling fluid transfer to the rotating wafer stage for precise photolithography processes.

• Etchers: Enable uninterrupted flow of control signals and etching gases to the rotating chamber for controlled etching of circuit patterns.

• Chemical Vapor Deposition (CVD): Ensure seamless transfer of control signals and precursor gases to the rotating susceptor for uniform deposition of thin films.

Key Considerations for Semiconductor Applications

• Ultra-Clean Design: Semiconductor manufacturing demands an immaculate environment. Senring F-Series, dustproof and waterproof slip rings and rotary unions are designed with minimal particle generation and high corrosion resistance to prevent contamination.

• High-Speed Performance: Modern chip fabrication equipment operates at high speeds. Senring high-speed slip rings are built for low friction and minimal signal distortion to maintain performance at these speeds.

• Vacuum Compatibility: Some processes occur in vacuum chambers. Senring offers vacuum-compatible slip rings and rotary unions to operate seamlessly within these environments.
