Semiconductor Manufacturing — Custom Parts from China

Semiconductor equipment demands the tightest tolerances, the cleanest surfaces, and materials that survive plasma, chemistry, and vacuum. We make custom components for wafer handling, process chambers, and fab tooling — from first prototypes to repeat production.

CNC machining, 3D printing, injection molding, and sheet metal — four proven processes from one factory-direct supplier, with clean packaging and full inspection records.

How we help

Why Semiconductor Teams Choose YiguProto

Micron-Level Precision

We machine and measure to micron-level tolerances with CMM, optical tools, and surface profilometers. Tight flatness and fine finishes are standard work for us, not an exception.

Cleanroom-Grade Handling

Parts are ultrasonic-cleaned, passivated where needed, inspected, and double-bagged in clean packaging before they ship. No particles, no fingerprints, no surprises at your dock.

Materials for Harsh Processes

We work in PEEK, PTFE, alumina, fused quartz, 316L stainless, and high-grade aluminum — chosen for chemical resistance, vacuum compatibility, and low outgassing.

Engineering & DFM Support

Our engineers review your files before production. You get practical feedback on datums, tolerance chains, wall thickness, and stress relief — at no extra cost.

Speed That Protects Uptime

Most quotes come back within 24 business hours. Prototypes and spare parts ship in days — because a tool down in a fab cannot wait for a replacement part.

Your Designs Stay Yours

All files and ideas are treated as confidential. We sign NDAs whenever you need one — before you send a single drawing.

Four Ways We Build Semiconductor Equipment Parts

Not sure which process fits your part? Start here. Each card shows what the process does best and the semiconductor components we make with it.

CNC Machining

Parts cut from solid metal, plastic, or ceramic. The default choice for wafer handling, chamber internals, and anything that must hold a micron-level tolerance. No tooling needed for prototypes.

Typical parts:

  • End effectors and vacuum chucks
  • Showerheads and distribution plates
  • Precision mounts and alignment plates
  • Test sockets, contact pins, and connectors
See CNC details →

3D Printing

Parts built layer by layer from your CAD file. The fastest way to prove a design, build a production jig, or make ESD-safe fixtures — no molds, no cutting tools.

Typical uses:

  • ESD-safe assembly and handling fixtures
  • Wafer cassette and carrier prototypes
  • Manifolds with built-in cooling channels
  • Low-volume and one-off replacement parts
See 3D printing details →

Injection Molding

Plastic parts made in volume. The economical route for chemical-resistant parts, ESD-safe housings, and repeatable batches of identical components.

Typical parts:

  • ESD-safe chip trays and carriers
  • Cable glands, seals, and valve bodies
  • Insulator bushings and washers
  • Chemical-resistant PVDF / PTFE parts
See molding details →

Sheet Metal Fabrication

Flat metal cut, bent, and welded into parts. The go-to choice for cabinets, enclosures, and frames that house and protect fab equipment.

Typical parts:

  • FAB cabinets and electrical enclosures
  • Gas boxes and bezels
  • Cable trays and raceways
  • Cleanroom brackets and panels

Solution 01

CNC Machining for Semiconductor Equipment

CNC machining cuts a part out of a solid block of metal, plastic, or ceramic. A computer-controlled tool removes everything that is not the part. What stays is accurate down to a few microns — and identical every time.

This is the backbone process of semiconductor equipment. Wafer handling parts, chamber internals, and precision mounts almost always start here. In a fab, one particle or one misaligned mount can scrap a wafer worth thousands of dollars. Precision is not optional.

What we machine for semiconductor equipment

  • End effectors, robotic arms, and wafer carriers
  • Vacuum chucks and precision motion stages
  • Showerheads, distribution plates, and focus rings
  • Precision mounts, alignment plates, and optical holders
  • Test sockets, contact pins, and connectors

Common materials

6061 / 7075 aluminum316L stainless steelPEEKPTFEAlumina ceramicFused quartz

We hold tolerances to a few microns, verify with CMM and optical measurement, and control stress — roughing, stress relief, then finishing — so parts stay stable after machining. Every part is cleaned, passivated where needed, and packaged clean for shipment.

Molded chip trays and chemical-resistant insulators

Solution 02

Injection Molding for Semiconductor Parts

Injection molding makes plastic parts in volume. Plastic pellets are melted and injected into a steel mold. The part cools, hardens, and pops out — identical every time.

Once the mold exists, each part costs little and comes out fast. If your design is stable and you need thousands of chemically resistant or ESD-safe parts, this is the most economical route.

What we mold for semiconductor

  • ESD-safe chip trays and wafer carriers
  • Cable glands, O-rings, and seals
  • Insulator bushings and washers
  • Valve bodies and fluid fittings
  • Chemical-resistant PVDF and PTFE parts

Common materials

PEEKPVDFPPSPFA / PTFEAntistatic PCPOM

Chip trays and carriers come in ESD-safe compounds so static never touches your devices. For chemical lines, PVDF and PFA stand up to acids and solvents that destroy ordinary plastics. We make the molds in-house and use hot runner systems for clean, consistent parts.

Fabricated FAB cabinet and gas box

Solution 03

Sheet Metal Fabrication for Semiconductor

Sheet metal fabrication cuts, bends, and welds flat metal into a finished part. No molds are needed, so it works well for prototypes and for parts that change often.

It is the natural choice for the structures around a fab tool — the cabinets, enclosures, and frames that protect electronics and keep equipment organized.

What we fabricate for semiconductor

  • FAB cabinets and electrical enclosures
  • Gas boxes and bezels
  • Cable trays and raceways
  • Equipment frames and support structures
  • Cleanroom brackets and mounting panels

Processes & finishes

Laser cuttingCNC bendingPunchingWeldingPowder coatingPassivation

Stainless and coated steel resist the humidity and chemicals of a fab floor. Burr-free edges and flat, square bends matter here — they keep doors aligned, gaskets sealing, and panels free of particle traps.

3D printed fixtures and wafer carriers

Solution 04

3D Printing & Rapid Prototyping for Semiconductor

3D printing builds a part layer by layer, straight from your CAD file. There are no molds and no cutting tools — just the file and the printer.

Equipment teams iterate constantly. Print a fixture on Monday, test the fit on Tuesday, change the design on Wednesday. 3D printing turns that loop into hours and days, not weeks.

What we print for semiconductor

  • ESD-safe assembly and handling fixtures
  • Wafer carriers and cassette prototypes
  • Manifolds with internal cooling channels
  • Tooling, jigs, and check gauges
  • Low-volume and one-off replacement parts

Processes we run

FDMSLASLS (nylon)MJFSLM (metal)

ESD-safe filaments keep static away from sensitive devices. PEEK and high-temperature polymers handle hot zones and chemical exposure. Metal printing makes strong, functional prototypes from real stainless or tool steel. When the design is final, we move to CNC or molding for volume.

For semiconductor parts, we support one-off prototypes and full production runs. There is no strict MOQ. Many customers order a handful of spare parts at a time — we handle that every week.
We routinely hold tolerances down to a few microns and surfaces down to Ra 0.4 µm or better. We verify with CMM, optical measurement, and surface profilometers, and we document the results in your inspection report.
Parts are ultrasonic-cleaned, passivated where required, handled with gloves, and double-bagged in clean packaging before shipment. Materials are selected for low outgassing so they stay safe in vacuum systems.
CNC machined, 3D printed, injection molded, and sheet metal parts — from prototypes to repeat production. Common examples include end effectors, vacuum chucks, showerheads, chamber internals, test sockets, chip trays, ESD-safe fixtures, and FAB cabinets.
We follow strict inspection and documentation processes, and we support the certifications and records your industry needs — including ISO 9001 quality management, first-article inspection (FAI) reports, material certificates, and full dimensional reports on request.
It depends on the job. Aluminum 6061 is light, cheap, and easy to machine — great for structures and mounts. PEEK is the choice when the part faces chemicals, plasma, high temperature, or must not shed metal particles. Fused quartz and alumina go further still for optical or extreme-heat parts. Send us the application and we will recommend the grade.
