Laser Marking in the Semi-conductor Industry

Laser marking is a highly versatile and adaptable process, offering numerous advantages to its users, so it’s unsurprising that it is used by so many industries around the world. One such area is the semiconductor industry; you’ll find more information below on how marking aids this sector.

More information about the semiconductor industry

A semiconductor is a material which, as its name may allude to, can semi conduct electricity. This means that it is made up of conductive materials, which are generally in the form of metals, and nonconductive materials. These act like insulators, and are typically materials such as ceramic.

You can get pure element semiconductors, such as silicon, or compound semiconductors like gallium arsenide. Whether pure or compound, semiconductors play a huge role in our lives. They are a key element to many of the electronic items that we use every single day.

Infact, without semiconductors, we wouldn’t have the kinds of TVs, computers, radios, or phones that we have today, and we’d have lower quality medical diagnostic equipment too. While semiconductors aren’t necessary for the construction of these electronic items, they have enabled them to be smaller, faster, more reliable and of a much higher quality.

Given this, it has grown to become a huge industry, and now totals around $335.2 billion in value. As our need for electronics continues to grow, and products continue to become smaller and faster, it is likely that the use of semiconductors will simply keep on rising.

How is laser marking used in this sector?

This technology is most commonly used to create identification markings on the objects and materials that they are working with. This also happens to be their primary use within the semiconductor industry too.

There are many marks that are made on a semiconductor, as can be seen in the image on the item on this page, and this is done through marking with lasers. These marks must be extremely clear, machine-readable and not affect the surrounding area of the semiconductor at all, or affect the manufacturing process in any way.

This is why laser marking is such an integral process in the semiconductor industry. It is able to work with micro components extremely accurately, helping to create very small and precise markings without damaging the rest of the material.

Furthermore, given the fast-paced nature of this industry, it’s important that efficient and quick processes are used. Marking is the perfect solution for this. While it works quickly, it sacrifices nothing when it comes to control, precision and quality.

How can SPI Lasers help?

Given the fact that many semiconductors will often need many markings, it’s crucial that you’re using a laser system that you can rely on. Gas lasers can be used, but a fiber laser will provide you with the level of control that you need. Alongside this, fiber lasers have no service or maintenance costs as they utilise ‘fit and forget’ technology, making them perfect for an industry which is about cost-effectiveness and efficiency.

If you want to know more about how our fiber lasers can help, then we recommend taking a look at our range of pulsed fiber lasers. The redENERGY® G4 Pulsed Fiber Laser is a popular and highly efficient choice for those wishing to laser mark semiconductors.

Offering a wide range of frequency pulsing outputs, a high level of peak power, and a great level of control for their user, it is the perfect solution for laser marking. Fiber lasers are the newest of the laser technologies, and the wider range of benefits that they bring to the market matches the ever-increasing needs of the electronics and semiconductor industries.
