Why Precision Matters in Semiconductor Manufacturing

In semiconductor manufacturing, even the tiniest speck of dust can ruin an entire wafer of chips. That’s why precision isn’t just important—it’s absolutely necessary.

Our 5-axis machining capabilities let us create complex shapes with perfect accuracy. When making parts for plasma etch chambers, we need to achieve tolerances of ±0.001mm—that’s about 1/50th the width of a human hair! These tight tolerances ensure:

• Perfect wafer alignment for nanoscale features
• Consistent gas flow in process chambers
• Reliable vacuum sealing to maintain ultra-pure environments
• Precise electrical testing of completed chips

Our Advanced Manufacturing Processes

At Istar Machining, we use multiple advanced processes to create semiconductor components:

5-Axis CNC Milling

Our 5-axis machines can create complex 3D shapes in a single setup, maintaining tight tolerances throughout. This is perfect for making electrostatic chuck components that need perfectly flat surfaces with intricate cooling channels underneath.

EDM Wire Cutting

For extremely precise cuts in hard materials, we use EDM machining (Electrical Discharge Machining). This process can cut through materials like tungsten with accuracy down to 0.0001 inches.

Precision Turning

Our CNC turning services create perfectly cylindrical parts used in vacuum systems and gas delivery components.

Surface Grinding

When components need perfect flatness, our surface grinding services can achieve surface variations of less than 0.0001 inches across an entire part.

Quality Assurance for Semiconductor Components

Every semiconductor part we make goes through strict quality checks:

• CMM measurement to verify all critical dimensions
• Surface roughness testing to ensure mirror-like finishes
• Particle detection to confirm cleanliness standards
• Material certification to verify chemical composition
• First Article Inspection for new part designs

Real-World Applications

Our semiconductor CNC machining work helps create:

• Microprocessors for computers, phones, and servers
• Memory chips for data storage devices
• Sensor components for cameras, touchscreens, and IoT devices
• RF chips for wireless communications
• Power management ICs for efficient energy use
