Semiconductor

In the ever-evolving world of semiconductors, precision isn’t a luxury it’s a necessity. The microelectronic components driving everything from smartphones to AI servers rely on ultra-precise mechanical parts and assemblies. Behind the scenes, Yicen Precision delivers the critical CNC-machined components that enable fabrication, testing, and packaging processes across the global semiconductor value chain.

Why CNC Machining Matters in the Semiconductor Industry

Semiconductor manufacturing operates on a microscopic scale, but it depends on high-precision macroscopic components chambers, fixtures, brackets, and tooling systems that must meet tight tolerances and endure harsh chemical, thermal, and vacuum environments.

At Yicen Precision, we specialize in CNC machining of high-purity materials and tight-tolerance parts used in front-end and back-end semiconductor production. Our capabilities help OEMs and fab equipment manufacturers maintain accuracy, repeatability, and uptime.

We manufacture components for:

• Wafer processing tools (etch, deposition, CMP)
• Backend assembly and test equipment
• Cleanroom-ready automation fixtures
• Thermal and vacuum systems
• Semiconductor-grade hardware assemblies

CNC-Machined Parts for Semiconductor Equipment

Yicen Precision provides custom components that meet the high cleanliness, material compatibility, and dimensional stability required for semiconductor-grade equipment. Key applications include:

Vacuum and Chamber Components

We machine precision components for ultra-clean, vacuum-sealed environments:

• Plasma etching chamber parts
• ALD/CVD/PECVD tool components
• Electropolished vacuum flanges and seals
• O-ring grooves and vacuum interface plates
• Quartz and ceramic-compatible hardware

Wafer Handling and Tooling Fixtures

Wafer processing relies on smooth, particle-free handling systems. We supply:

• Wafer chucks and carriers
• End effectors for robots
• Tool nests and alignment plates
• Substrate clamps and grippers
• High-precision locating pins and bushings

Thermal Management and Insulated Hardware

Heat control is critical for wafer uniformity and system reliability. We produce:

• Custom heat sinks and heat spreaders
• Cold plates with integrated channels
• Insulator brackets and thermal isolators
• Water-cooled enclosures and baseplates

Frame, Mounting, and Support Structures

Yicen Precision fabricates structural and alignment-critical parts for fab equipment:

• Structural brackets and CNC-milled frames
• Linear motion plates and rail mounts
• Aluminum machine bases and panels
• Cleanroom-friendly access covers

From Prototype to Production: Our Process

Yicen Precision supports semiconductor clients at all stages whether you’re prototyping a next-gen wafer handler or scaling up chamber components for mass production.

Rapid Prototyping

Fast CNC machining services allow for quick iteration during R&D, design validation, and pilot testing. We deliver prototype parts in as little as 5–7 business days.

DFM Support

We work directly with your engineering team to optimize parts for manufacturing. Our design-for-manufacturability (DFM) process reduces cost, improves fit, and accelerates production.

Cleanroom Packaging & Traceability

All parts can be cleaned, bagged, and packaged to cleanroom standards, with complete traceability and inspection reports for critical applications.

Production Machining

Whether you need a batch of 10 parts or 10,000, Yicen Precision delivers repeatable quality, tight tolerances, and consistent documentation for your supply chain.
