Find out what laser marking is all about


Before manufacturing silicon wafers, marking them with a laser is essential. Using a laser machine, permanent marks are created on semiconductor packages with a concentrated light beam. There is no normal word for a laser; it is actually an acronym that stands for “Light Amplification by Stimulated Emission of Radiation”, a focusing and directing technique. Wafers are laser marked throughout the manufacturing process, allowing them to be tracked, using a laser marking machine that can be programmed to meet specifications. Wafers should be able to be detected by machines thanks to this laser marking. A very finely detailed mark must also be used since the marking can’t affect or damage underlying processes. High-precision lasers are necessary. For more information, visit

What is the source of silicon wafers?

How are silicon wafers identified by laser marks? Each type of electronic device uses wafers as a semiconductor. Silicon wafers resemble disks because they are rounded disks with a mirror-like surface. Because silicon wafers are impurity-free, extreme care must be taken when laser marking them.

Laser Marking: A Quick Overview

The marking of silicon wafers requires interaction with a computer. A map of the wafer appears on a marking document at this point in the process. It describes the parameter values, functions, and other attributes of the wafer.

Viewing your data from the other side of the screen will allow you to see how it is being translated into silicon. Once the laser marking machine is set up properly, the wafer can go into the laser marking machine. The wafer is brought to the marking station by a mechanical hand. Since the entire process will be automated, no human interaction will be required. A laser beam will be emitted onto the surface of the water once the machine locates the target location. After completing the process, the completed project is positioned in the receiving box, and it can be removed once the process has been completed.

A number of advantages are offered by laser marking



Manufacturing wafers with laser marking is a highly effective process due to its precision. Using the company’s advanced technology, the company captures even the tiniest details with great accuracy. Silicon wafers have markings a few millimeters thick that computers can read, so tracking silicon wafers is simple.


Laser marking is fast and precise as well as highly precise. Stacking, marking, and completing the laser marking of silicon wafers takes only minutes. Laser annealing leaves no marks on the surface, despite being somewhat slower than other marking methods.

Only the topmost layer

Surfaces do not actually lose silicon when laser marking is performed. Instead, the laser marks only change the color beneath the silicon surface. There is no damage to the silicon itself.

There is a long-term effect

Markings are permanently etched into silicon wafers. A warm mark is usually left beneath the surface, making it difficult for it to fade.

Automating a process to its fullest extent

Automated processes are used throughout. Users do not have to interact with the system. Silicon wafers are picked up by mechanical arms and transported within the machine in order to be marked by mechanical arms. Due to this, laser marking machines are completely safe to use, since once the surface color is changed, the lasers will not interact with the wafer. This considerably reduces the likelihood of costly errors occurring. Reducing human error is an important factor in reducing costly mistakes.

Environmentally friendly

As a chemical-free and inkless method of marking, laser marking is very environmentally friendly. In addition to being very efficient, lasers also consume very little energy, making them perfect for marking silicon wafers.
