How do you sputter gold? 5 Key Steps to Understand the Process

Gold sputtering is a technique used to deposit a thin layer of gold onto various surfaces such as circuit boards, metal jewelry, or medical implants.

This process is part of physical vapor deposition (PVD) and involves the ejection of gold atoms from a target material, typically a disc of solid gold or gold alloy, through the bombardment of high-energy ions in a vacuum chamber.

5 Key Steps to Understand the Process

How do you sputter gold? 5 Key Steps to Understand the Process

1. Vacuum Chamber Setup

The process begins in a vacuum chamber where the target material (gold or gold alloy) and the substrate (the surface to be coated) are placed.

The vacuum environment is crucial to prevent contamination and to allow the gold atoms to travel directly to the substrate without interference.

2. Bombardment with High-Energy Ions

High-energy ions are directed at the gold target.

This ion bombardment causes the gold atoms to be ejected from the target in a process known as sputtering.

The ions typically come from a gas like argon, which is ionized within the chamber to provide the necessary energy.

3. Deposition of Gold Atoms

The ejected gold atoms travel through the vacuum and deposit onto the substrate, forming a thin, uniform layer of gold.

This deposition process is carefully controlled to ensure the desired thickness and uniformity of the gold layer.

4. Types of Gold Sputtering

DC Sputtering

This is one of the simplest and least expensive methods where a direct current (DC) power source is used to excite the target material.

It is commonly used due to its simplicity and cost-effectiveness.

Thermal Evaporation Deposition

In this method, the gold is heated and evaporated using an electrical resistive heating element in a low-pressure environment.

The evaporated gold then condenses on the substrate.

Electron-beam Vapor Deposition

This technique uses an electron beam to heat the gold in a high vacuum environment.

The high-energy ions from the electron beam cause the gold to evaporate and subsequently condense on the substrate.

5. Applications and Advantages of Gold Sputtering

Durability and Corrosion Resistance

Sputtered gold films are exceptionally hard, durable, and resistant to corrosion and tarnishing.

This makes them ideal for applications in the watch and jewelry industry where durability and appearance are critical.

Fine-Grain Control

The process allows for precise control over the deposition of gold, enabling the creation of custom patterns and shades, such as rose gold, by controlling the mix of gold and copper and the oxidation of free metal atoms during sputtering.

All types of gold sputtering require specialized sputtering equipment and controlled conditions to ensure the quality and uniformity of the gold layer.

Manufacturers produce specific equipment for this purpose, and the process can be performed by private firms upon request.
