If a group of silicon wafers is placed in front of you, they are all probably going to look very similar, if not exactly the same. However, what the naked eye might not be able to see are the nearly microscopic differences that can completely change their function. That’s why laser marking them is so important, as it can easily signify a millimeter’s worth of a difference.
The word “laser” isn’t just some normal word someone made up. It’s actually an acronym that stands for “Light Amplification by the Stimulated Emission of Radiation.” Quite the mouthful, isn’t it?
When you engrave something, you are cutting away or carving into the surface of an object. For the text or design to appear, you need to take away from the object. Since silicon wafers are so delicate and require extreme precision for them to function properly, engraving would not be a viable option. In fact, it would completely ruin the wafer!
During the silicon wafer manufacturing process, an automated machine is programmed to use lasers to mark the wafer without removing any portion of the surface level. Instead, the laser simply causes a slight color change below the surface, keeping everything in perfect condition.
