Semiconductor Surface Treatment in Singapore

Contamination-controlled plating & anodizing for wafer-fab and equipment makers

Semiconductor Industry Overview

Singapore is one of the world's most important semiconductor manufacturing hubs, and the equipment that builds, handles, and tests wafers depends on flawless surface finishes. Active Treatment provides semiconductor surface treatment for chamber components, end-effectors, gas-line hardware, jigs, and precision tooling used across front-end and back-end processes.

Our finishes are engineered for cleanliness, dimensional precision, and resistance to aggressive process chemistries — from electroless nickel on aluminium handling parts to hard anodizing on vacuum-chamber fixtures.

Surface Treatment Challenges in Semiconductor

• Particle and ionic contamination must be kept to an absolute minimum to protect wafer yield.
• Components are exposed to corrosive process gases, plasmas, and wet chemistries that attack untreated metal.
• Tight dimensional tolerances leave very little room for coating build-up or stripping damage.
• Aluminium tooling needs hard, non-shedding surfaces that resist wear without generating particles.
• Traceability and repeatable finish quality are required across large production volumes.

Recommended Finishing Processes

We recommend the following finishes for semiconductor components, each selected for cleanliness, corrosion resistance, and dimensional control:

• Electroless Nickel Plating — Electroless nickel gives complex parts a hard, uniform, low-particle surface with even coverage in blind holes and threads; high-phosphorus grades add near-amorphous, highly corrosion-resistant protection for parts exposed to aggressive process chemistries.
• Gold Plating — Gold plating delivers stable low-resistance contact surfaces and excellent corrosion immunity for connectors, electrodes, and RF hardware.
• Aluminium Anodizing — Anodizing hardens aluminium fixtures and chambers, producing a dense, non-conductive oxide that resists wear and chemical attack.
• Hard Black Anodizing — Type III hard black anodizing provides a thick, abrasion-resistant, low-reflectance surface for high-wear and optical-sensitive tooling.

• Fast local turnaround from our Toa Payoh facility.

Semiconductor Surface Treatment FAQs

What surface treatments are used for semiconductor equipment?

The most common semiconductor surface treatments are electroless nickel plating, hard anodizing, and gold plating. Electroless nickel protects aluminium and steel handling parts, hard anodizing toughens aluminium chamber and fixture surfaces, and gold plating provides stable electrical contacts. The right choice depends on the process environment and the part's function.

Why is electroless nickel preferred for semiconductor parts?

Electroless nickel deposits a uniform, low-particle layer even on complex geometries, blind holes, and threads — without the thickness build-up at edges seen in electroplating. This dimensional consistency, combined with strong corrosion resistance, makes it ideal for handling hardware and tooling where cleanliness and tolerance control are critical.

Can you treat aluminium vacuum-chamber components?

Yes. We hard anodize aluminium chamber parts and fixtures to create a dense, wear-resistant oxide that withstands plasma and chemical exposure, and we can apply electroless nickel where a conductive, solderable, or repairable surface is required. Masking protects sealing faces and critical bores.

Do your finishes meet cleanliness requirements for wafer fabs?

Our processes emphasise thorough cleaning, controlled rinsing, and careful handling to minimise particle and ionic contamination. We work to customer specifications and can provide thickness and adhesion verification so finished parts integrate reliably into fab environments.

Where is your semiconductor surface treatment carried out?

All work is performed at our facility in Toa Payoh, Singapore, giving local semiconductor manufacturers and equipment makers fast turnaround, easy sample approval, and direct technical support.
