Laser Marking in the Semiconductor Industry

Semiconductor manufacturing is the process used to create semiconductor devices, which are electronic components made from semiconductor materials. These materials are typically silicon-based, but can also be made from other materials such as germanium, gallium arsenide, or silicon-germanium. The parts are commonly used in computers, hand-held electronic devices such as mobile phones, tablets and electronic book readers, wearable devices and consumer electronics.

This manufacturing process starts with wafer fabrication, in which these materials are purified and shaped into thin disks called wafers. These wafers are then subjected to a series of complex processes that add electrical components such as transistors and other circuit elements. Also, many parts require laser marking before they are packaged and shipped to the customer.

Semiconductor manufacturing is a highly complex and precise process, and even small changes in the fabrication process can significantly impact the finished product's performance. That said, using precise and professional equipment is paramount, including the right semiconductor laser marking systems.

These laser marking machines are used to create semiconductor devices such as semiconductor chips, wafers, printed circuit boards (PCBs), integrated circuits (ICs), and other semiconductor devices.

Until recently, IC chips were only marked with lot codes. However, a growing need for encoded data has prompted many manufacturers to start using 2D codes.

KEYENCE’s 3-Axis laser markers can mark the top surface of IC chips and remove plating or coatings within the same process. Since the laser accurately scans only along the edges of the IC, flash burrs over the leads can be removed without causing damage to the inside of the package.

In the semiconductor industry, semiconductor laser marking is used extensively for part marking. This is because semiconductor laser marking machines offer many advantages over other types of machines. For example, semiconductor laser marking machines can mark very small parts with a high degree of accuracy. In addition, semiconductor laser marking machines are very fast, so they can mark large quantities of parts in a short period of time.

The process is also highly versatile, allowing for a wide range of semiconductor part designs and markings. Additionally, semiconductor laser marking is an environmentally friendly alternative to other part marking processes, such as etching or screen printing, because it does not use any consumables. As a result, semiconductor laser marking machines are an essential part of the semiconductor industry.
