Custom Fabrication

Custom Semiconductor Fabrication & Machining

CAD design, precision machining, fabrication, welding, cutting, and finishing support for obsolete or application-specific semiconductor equipment parts.

Technical Support

A replacement path when standard parts are unavailable

Custom manufacturing may support a legacy tool when a component is obsolete, unavailable, or requires an application-specific change. Successful projects begin with complete dimensional, material, interface, process, and operating requirements.

01

CAD & Modeling

Drawings, samples, measurements, interface details, and functional requirements can be developed into a controlled manufacturing definition.

Capture the full requirement

Critical dimensions, tolerances, materials, finishes, and revision control should be established before production.

02

Precision Machining

Machining options may include complex multi-axis work and tight-tolerance components for semiconductor equipment applications.

Manufacturability review

Geometry, tolerance stack-up, material behavior, quantity, inspection needs, and cost influence the manufacturing approach.

03

Cutting & Welding

Water jet, laser cutting, TIG, MIG, and laser welding may support frames, brackets, panels, enclosures, fixtures, and equipment modifications.

Process selected by application

Material thickness, heat input, distortion, cleanliness, strength, and finish requirements guide process selection.

04

Finishing & Coatings

Potential finishing paths include electrostatic discharge coating, electroplating, powder coating, anodizing, and other application-specific treatments.

Consider the fab environment

Chemical exposure, vacuum compatibility, conductivity, corrosion, wear, cleanliness, and appearance requirements should be documented.

Controlled requirements

Dimensions, materials, tolerances, and finishes are defined before production.

FAQ

Frequently asked questions

Can you reproduce an obsolete semiconductor equipment part?

Potentially. A sample, drawing, measurements, material requirements, interfaces, and operating conditions are needed to evaluate feasibility.

Can custom parts be made from only a photo?

A photo is useful context but is rarely sufficient by itself. Accurate dimensions, tolerances, materials, finishes, and functional requirements are normally required.

What fabrication capabilities are available?

Potential capabilities include CAD, modeling, precision machining, water jet and laser cutting, welding, coatings, plating, powder coating, and anodizing.
